day_1_date: 2014-04-11
day_1_weather_forecast: A major spring storm will affect the region from the Mississippi to the East Coast from Monday, April 14, 2014, to Tuesday, April 15, 2014, driven by a sharp frontal complex. Hazards include severe thunderstorms in the South, torrential rain showers, and heavy snow from the Central Plains to the Great Lakes. Significant snowfall is expected in the Central and Northern Appalachians, with lower elevations, including the Northern Piedmont to New England, possibly receiving snow as well. The second half of the forecast period will see widespread rain and snow as additional systems move across the Northwest and Northern Plains, while the Southwest remains dry.
day_1_temp: '68.0'

day_2_date: 2014-04-12
day_2_weather_forecast: A strong frontal system will move off the east coast, leading to a slowdown in the west-to-east progression of weather systems across the United States. This results in high variability and low confidence in forecasting individual weather systems after day 5. Cooler daytime temperatures are expected nationwide due to clouds and precipitation. Weaker systems are anticipated to impact pressure, wind, and temperature forecasts, with fairly uniform conditions predicted. Overall, clouds and precipitation are expected to contribute to the cooler daytime temperatures, while the Southwest remains sheltered from significant moisture and stronger weather systems.

day_2_weather_forecast: The forecast from April 19 to April 23 indicates a complex flow pattern across the eastern U.S. with increased uncertainty. A moderate spring cutoff system will amplify and move into the southern Great Basin and Colorado River Basin, enhancing precipitation. The southern stream jet will contribute to convective precipitation in the southern plains, Mississippi Valley, Ohio Valley, and Carolinas. By day 6-7, the Gulf of Alaska's energy will approach the West Coast, while a weak cold advection pattern will persist in the Pacific Northwest, with temperatures 10-15°F above normal across the West before a cooling trend as the eastern Pacific trough arrives. Light precipitation, with pockets of snow in northern areas, is expected in the Northeast and lingering clouds/rainfall in the Southeast. The northern plains may experience increased precipitation, potentially heavy in some regions.

day_2_weather_forecast: Overall flow pattern is resolved over the eastern Pacific, with agreement on large-scale features from the West Coast to East Coast. A negative-tilt trough aligns along 50°N latitude, bringing an associated upper-level trough/cold pool. Good clustering in model runs through Day 5, then a deep cyclone may cause strong northwesterly shear and uncertainty regarding the low's path through the Midwest on Day 6. Preference is for a weaker surface feature tied to occlusion, with increased isolated convection and thermal contrasts anticipated.
Post-frontal cooling expected across New England into early Day 6, with modest precipitation and stronger convection in advance. Mid-upper level trough energies will interact over the Eastern U.S., resulting in precipitation and cooling. Increased moisture and heavier precipitation potential, especially in the Northwestern U.S. and Northern Rockies, with isolated wintry precipitation in the Northwest’s highest elevations. A dynamic trough and surface system expected to impact the Northwestern U.S. in about a week.

day_2_weather_forecast: A stable wave pattern will create migratory systems across the lower 48 states. The forecast anticipates a transition from a multi-wave split-flow to higher-amplitude troughs and wide shortwave ridges, leading to a spring rain and high elevation snow pattern in the northwest after day 5. Early day 3 systems will impact the northern Rockies. Mainly dry and breezy Pacific cold fronts will occur along the I-80 corridor, while warm advection flows northward from the southern plains to the Midwest and Ohio Valley. A dryline convective pattern may generate hit-and-miss rainfall in West Texas, eastern New Mexico, western Oklahoma, eastern Colorado, and western Kansas. Temperatures are expected to rise quickly and potentially spread into the lower Missouri Valley, Ozarks, and western Ohio Valley by day 5.

Chilly weather is expected for the northern one-third of the country, with a surge of modified Arctic air establishing a stationary baroclinic zone between I-70 and I-40. Below or much below average temperatures are forecast for northern regions, leading to potential snow at lower elevations in MT, WY, SD, and ND. The WPC medium range product favors the ECMWF and EC ensemble mean due to better continuity. The operational GFS exhibits a fast bias, while the Canadian ensemble offers slower solutions for the central U.S. trough. Severe weather potential is highlighted in the warm sector by the Storm Prediction Center, with repeated rounds of moderate to heavy rain anticipated, particularly in the lower Ohio Valley.

day_2_weather_forecast: Models predict a decrease in the amplitude of the 500 mb trough in the east as a closed low progresses northeast into the Canadian Maritimes by May 5. Following this, a high amplitude ridge is anticipated to build across the Northern Plains and Mississippi Valley, while uncertainty remains regarding the West Coast trough's amplitude. The ECMWF ensemble shows less amplification compared to the GEFS members, which suggest higher amplitude development in California on May 6. An intermediate model solution has been used to address discrepancies. Additionally, predictions indicate that the resolution of the climate system will be influenced by Typhoon Tapah's extratropical transition. The latest ECMWF model indicates reduced likelihood of southern stream wave development near the Southeast Coast, with increased focus on a dominant northern stream low impacting Ontario and Quebec instead.

Models indicate an increased likelihood of a deeper western trough over the coming days, particularly by day 5 (Monday), though confidence wanes for days 6-7 (Tuesday-Wednesday). A broad area of precipitation is projected from northern-central parts of the west into the northern plains, and eventually the upper Mississippi Valley and Great Lakes, with snow levels decreasing as the upper trough settles. Light rainfall and possibly isolated snow are expected in northern regions, while Florida could experience locally moderate-heavy rainfall. Temperatures in the central-southern Rockies and plains may exceed normal by 15-20°F, possibly reaching daily record highs, but northern areas will see daytime highs 5-15°F below normal as the weekend progresses and the trough amplifies.

day_2_weather_forecast: Significant amplification of an eastern Pacific trough will move into the west, bringing height falls to the plains by mid-next week. A ridge is expected to build into the east-central/southeastern states, while the northeastern CONUS trough drifts into the western Atlantic. The most active weather will affect the Pacific Northwest and Great Lakes regions. Days 3-4 (Sunday-Monday) indicate a consensus approach favoring the GFS and ECMWF models. After Monday, confidence in details decreases, leading to a forecast for days 5-7 based on a blend of models. Key uncertainties involve the evolution of mid-level energy affecting the northeast and surface low pressure, with potential variations in the strength and track of the low pressure system in the central plains.
Precipitation is expected to be highest in favored terrains of the Northwest, northern high plains, eastern slopes of the Rockies, and the Upper Mississippi Valley due to warm advection. Temperatures in the central and southern plains may reach 15-20°F above normal from Sunday to Tuesday, with some locations approaching record highs. A vigorous surface low will cross New England Sunday night, generating varying intensities of rainfall. A stalled front may focus areas of rainfall next week, and convection may develop over the central-southern plains by Thursday.

day_1_weather_forecast: High amplitude and blocky flow patterns over North America, with a strong ridge supporting a broad trough over the eastern continent. The eastern U.S. will see a slow-moving frontal boundary bringing locally heavy rainfall from the southeastern plains eastward. Potential for surface reflection and enhanced precipitation due to deep moisture from the Gulf of Mexico and eastern Caribbean. The western U.S. will experience very warm to hot temperatures, with highs 10-20°F above normal, possibly reaching record values. A significant temperature contrast will occur, with central states seeing highs 10-20°F below normal and eastern locations remaining 10-15°F above normal. Overall, the central and eastern regions will trend towards near or below normal temperatures by late week, with extreme negative anomalies expected in the northern tier and Great Lakes regions. Persisting moisture and conditions may lead to rain and possibly high elevation snow in the northern-central Rockies.

day_2_weather_forecast: An amplified mid-upper level trough will dominate the eastern U.S. from May 14 to May 18, 2014. A significant trough from Canada will enhance stream phasing and surface responses. The western U.S. will experience very warm to hot temperatures, with the potential for record highs near the west coast. Cooling trends and increased moisture are expected in northern-central areas by next weekend as the ridge weakens. Locally heavy rainfall is likely from the Mississippi Valley to the East Coast starting Thursday, influenced by moisture from the northern Caribbean and strong Atlantic inflow. Much of the central-eastern U.S. will see below to well below normal daytime highs, with temperatures at least 10°F below normal from the Plains to the Ohio Valley/Great Lakes region. A moisture band will establish over the northern-central Rockies/High Plains.

day_2_weather_forecast: A deep mid-upper level trough will settle over the eastern U.S. and gradually weaken as it moves toward the east coast. Eastern Pacific energy will arrive in the west, displacing a strong ridge along the west coast. Very warm to hot conditions are expected in the west, with potential daily record highs on Thursday and Friday, anomalies of 10-20°F. Increased moisture and light to moderate precipitation are expected across the northern third of the west from the weekend into early next week, reaching the northern plains late in the period. Rainfall will occur ahead of the eastern trough due to a cold front pulling moisture from the eastern Gulf and western Atlantic, enhancing rainfall along the east coast late in the week. Below to well below normal temperatures in the central and eastern states are expected to moderate by Sunday-Monday as the trough weakens. Additional precipitation will develop over the northern-central Rockies and high plains, extending into the east in a more scattered form.

day_2_weather_forecast: The extended forecast shows an amplified flow across the lower 48 states, with troughs along both coasts and a broad ridge from the continental divide to the Great Lakes and southern regions. A system moving through the south central plains (Kansas/Oklahoma) is expected to continue its upper-level trough migration around 27/12Z, transitioning from an MCS to an MCV-type configuration, leading to pulsing convective activity and variability in heavy rainfall axes. Significant rainfall amounts are anticipated in the lower Arkansas River basin, the lower Mississippi River basin, and throughout central and northeast Texas. A positive-tilt trough is approaching the western U.S., causing a secondary system to develop along the California coast. Healthy height falls are expected along the north central California coast, with minimal continuity change in the cutoff low as a weaker cold front emerges downstream affecting the northern high plains, where cold advection is set to weaken. Additionally, a Canadian maritime trough will influence conditions from the Gulf of Maine to Cape May, with transitions in New England away from northwest flow patterns. The forecast indicates substantial wet conditions across the south central plains, with a pattern consistent with 'ring-of-fire' convection developing along the continental divide.

Significant rainfall is anticipated across eastern Oklahoma and Texas (I-35 eastward), the Southern Ozarks, and the lower third of the Mississippi Valley, with isolated clusters of showers and thunderstorms to the northeast and east of the dissipating system. Humidity levels will subtly increase with mid-level cloudiness and high-elevation convection as a Pacific trough moves inland. Broad ridging is expected in the Southeast and Great Lakes regions, with a notable focus shift from the Southern Plains to the Intermountain West and Desert Southwest in the latter half of the forecast period.

day_2_weather_forecast: The extended forecast indicates low confidence due to significant differences in model solutions. An upper ridge remains over northern Mexico with a mean trough extending northeast across the western US. Southwesterly flow affects the northern third of the country. The ECMWF model predicts a more pronounced shortwave trough moving east-northeast across the north central US by Tuesday, advancing toward Ontario and Quebec by Thursday. Other models suggest a flatter system. A blend of 70% ECMWF and 30% GEFS was used, as both models show relatively similar mean sea level pressure forecasts from days 3 to 7, with a stronger emphasis from days 5 to 7.

day_2_weather_forecast: The weather forecast from June 4 to June 8, 2014, indicates the presence of a ridge over northern Mexico, a western North American mean trough, and a trough affecting southeastern Canada and the northeastern U.S. There is considerable uncertainty in forecast details, particularly for the eastern CONUS and Gulf of Mexico, with a favored blend of the 00Z ECMWF mean and recent ECMWF runs for guidance.
Key weather events include potential heavy convection along a wavering surface front from the central/south-central plains into the mid-Atlantic, with locally heavy rainfall expected due to midweek and weekend surface wave interactions. Northern plains may experience heavy rainfall from a cold front, and organized rainfall is likely in the northeast due to low-pressure consolidation.
Temperature-wise, areas west of the Rockies will likely see near to above normal readings, with anomalies of +10 to +15°F possible in central-northern California. In the southern high plains and south-central plains, temperatures may reach 10-15°F above normal midweek, with the northern high plains experiencing cooler highs relative to normal. The rainfall forecast for Florida remains uncertain, with expectations of lighter rainfall compared to GFS models, but more than recent ECMWF runs.

day_2_weather_forecast: The weather forecast from June 5 to June 9, 2014, indicates the influence of three primary longwave troughs across the US, leading to variable timing and intensity predictions. Above normal temperatures will occur in the southwest, southern Rockies, and plains, shifting to slightly below normal by days 6-7 due to a cold front moving through. A closed anticyclone over northern Mexico is contributing to temperature anomalies. A closed low is expected to move onshore in British Columbia by June 8, affecting the northern Rockies and high plains overnight into June 9. Confidence in the operational ECMWF model is low, particularly for predicting below normal temperatures in the northern Rockies. In the eastern US, a deep layer trough will bring higher pressure across the Great Lakes. Discrepancies arise as another longwave trough approaches the Upper Mississippi Valley and Great Lakes; GFS models are outliers with a stronger surface low inconsistent for this time of year. A blend of model outputs is used for more reliable forecasting.

day_1_weather_forecast: Blocking upper-level ridge near the Davis Strait will influence weather patterns, with models showing improving agreement. Expect precipitation from a mid-level disturbance moving from Kansas/Missouri to the Great Lakes by Thursday, separated from the northern stream. A secondary low pressure will develop from Eastern Montana to Northern Minnesota. Troughing in the Pacific Northwest will lead to cooler temperatures, generally 4-8°F below climatological averages, while southeastern regions may experience warmer conditions in the short term. Widespread but light precipitation is forecasted over the Southern Plains and Mississippi Valley, triggered by a front from the Great Lakes. Overall, lower heights are expected to shift into the Northeast and Mid-Atlantic.

day_2_weather_forecast: Progressive pattern favored over the CONUS with distinct features including blocking ridging at higher latitudes and a persistent ridge over west central Mexico. Variable temperatures expected with widespread precipitation chances outside the southwestern states. Three to four weather systems anticipated, with model uncertainty noted, particularly as GFS/GEFS diverge from ECMWF-led consensus. Initial closed low near Missouri expected to drift into the Great Lakes, weakening as it merges with a northern stream shortwave. Significant precipitation likely in southern plains and Mississippi Valley, though not heavy due to afternoon convection. Incoming upper low from the northeast Pacific will influence weather patterns with cooler temperatures in the Pacific Northwest, 4-8°F below normal. Final northern stream system to bring changes, but confidence in timing is average. Potential tropical or quasi-hybrid system moving northeast from the Yucatán, with some model support, though overall potential downplayed by NHC.

By day 5, notable differences emerge, particularly in east central Manitoba regarding the 500mb circulation cutoff. The GFS predicts an earlier cutoff compared to the Canadian model, while the ECMWF suggests a continuous wave pattern.
Weather impacts for days 6-7 will largely depend on convective initiation and propagation, with negligible Gulf of Mexico influences. A slower evolution of the cutoff system is forecasted for northern/central Florida. A lead system is organizing over southern central Canada, with broad southwest flow influencing the upper Midwest. The cold front will slowly progress over Minnesota and Iowa, creating a potential for heavy rain from Saturday to Monday due to high moisture and instability (CAPE values of 1000-2000 J/KG and PW values of +1 to +2 standard deviations).
Temperatures are expected to be near to above normal in the central Plains, with highs reaching 5-10°F above climatological norms in the southwestern states. Some areas may exceed 110°F, and Death Valley could see temperatures over 120°F by Wednesday. Meanwhile, Pacific Northwest and Northern Rockies temperatures are expected to remain cooler.

day_2_weather_forecast: A broad subtropical ridge will dominate the Gulf Coast and Desert Southwest. An active weather pattern is anticipated in the eastern parts of the Northern and Central Continental Divide due to two Pacific systems bringing cold fronts across the US/Canadian border. A defined 500mb closed low is expected to form over Southern Canada by Sunday, leading to cooler temperatures in the Upper Midwest next week and a heavy rainfall threat due to a lingering frontal boundary over MN/IA/NE.
The Southern Plains, Southwest, and Southeast will experience rising temperatures with triple-digit heat, especially in the Rio Grande Valley and mid to upper 90s in the Lower Mississippi Valley and Alabama/Florida Panhandle, contributing to oppressive heat indices. Precipitation is likely across most Northern Tier states with the possibility of deep convection in the Central Plains, Ozarks, and Upper Portions of the Missouri and Mississippi Valleys.
A significant cooldown is forecasted for the Dakotas and Great Lakes regions due to a secondary cold front moving southeast into the St. Lawrence Valley and Northern New England by late in the period. Humidity levels will be elevated in the Lower Mississippi Valley and Alabama/Florida Panhandle, exacerbating heat conditions, while the Desert Southwest will experience a notable heat event with dangerous heat indices.

day_2_weather_forecast: An active summer weather pattern is developing over Canada, with a stable subtropical ridge influencing warmer temperatures in the southern regions. A mid-level/upper-level Pacific trough and associated surface fronts will bring variable weather conditions across the lower 48 states from June 30 to July 4, 2014. Very hot conditions are expected, especially under the upper-level ridge in the Southwest, with temperatures 5-10°F above normal, particularly in California due to thermal trough effects. Precipitation predictability is low across the Midwest, Mid-Mississippi Valley, Ohio Valley, and Appalachia due to warm-sector convection.
The GFS model indicates temperatures in the Great Lakes region will be 2-2.5 standard deviations below normal, migrating eastward, while the ECMWF suggests temperatures 1 standard deviation below normal over Lake Superior. A deep cyclone will move through Southern Canada and the Great Lakes, generating two cold fronts. The first front will advance toward the Ohio Valley and Ozarks, decaying along the subtropical ridge, while a secondary Canadian airmass will deliver drier air to the Northeast by the end of the forecast period. Isolated convective activity is expected due to terrain influences. Overall, warm and dry conditions will prevail as the warm dome of high-desert air migrates northward.

day_2_weather_forecast: A warming trend is expected over the western-central continent, leading to a significant weather pattern. A mid-upper level ridge will build, resulting in cooling and drying conditions downstream. A cooling surface front will move from the northeast Pacific to the western and northwestern US, dropping temperatures in these areas. Heavy convection is anticipated between the north-central and eastern US from Tuesday to Saturday, increasing precipitation levels due to deep moisture. Humidity levels will rise where heavy convection occurs. Limited rainfall is expected in favored terrains, with potential moisture influx into the southwest and south-central Rocky Mountains. Guidance shows mixed predictions for a possible hybrid low off the southeastern US, impacting convection with limited predictability. A mid-level trough will influence the eastern US later next week, with no substantial changes forecasted for the lower 48 states. A disturbance near the southeastern coast at coordinates 30N 78W will be monitored, influenced by mid-latitude troughs and an amplifying ridge near 110W. Details for late day 4 will rely on deterministic models including ECMWF, GFS, and UKMET.

day_2_weather_forecast: Amplified high-latitude flow across Canada brings several mid-level trough migrations through the Lower 48. Fresh Canadian air mass intrusions will affect the Missouri Valley, Great Lakes, and Northeast, resulting in drier conditions. A stable upper-level ridge will adjust eastward, with a temporary onshore flow in the Northwest as the ridge recovers over the Great Basin. A frontal passage is expected through the Northeast and Mid-Atlantic, likely leading to precipitation in those areas. Drier air from the northwest will decrease humidity levels, particularly along the I-95 corridor. Day 5 and Day 6 forecast a transition to drier weather in the eastern third of the U.S., with high pressure settling in. Meanwhile, the western region may experience little change as the Pacific front dissipates. Warm to hot temperatures will return to the Great Basin as high pressure builds, leading to a return of normal temperatures in that region.

A low pressure system off the southeast coast has an 80% chance of development and may deepen as it moves toward South Carolina and North Carolina, creating variability in weather conditions along the east coast, particularly around the 4th of July. The eastern trough is expected to bring precipitation, especially in the I-95 corridor from Virginia to New York. Central U.S. will experience a cooling trend with fall-like temperatures due to a high-pressure system, while southern regions will see a later warming trend as summer returns. The western U.S. will remain active, with light to moderate rain expected due to an anomalous jet impacting Washington and convection affecting conditions.

day_2_weather_forecast: Tropical Storm Arthur is expected to strengthen to hurricane status as it tracks near the southeast coast, leading to heavy rainfall and strong winds in the vicinity. A trough will transition the storm to extratropical status as it approaches the Canadian Maritimes. The weather pattern will shift to low amplitude flow typical for summer, with westerlies in the northern US and ridging in the southwest. A cold front will cross the northern tier, creating varying temperatures, initially up to 10°F below normal, but trending towards normal as drier conditions develop. Cooler and drier conditions are expected following Arthur, with warmer and more humid weather anticipated in the eastern regions early next week. Significant rainfall is possible due to frontal activity over the northern tier. Overall, near to above normal temperatures are expected in most of the west, with variations in the northern tier depending on frontal progression.

An extratropical transition is anticipated as it moves into the Canadian Maritimes. The flow pattern is stabilizing into a mean trough over Eastern Canada and the Northern/Central Eastern CONUS, with guidance indicating uncertainty in the Northwestern Canada/Alaska and Great Basin regions due to incoming Eastern Pacific energy. A cold front will cross the Northern Tier, bringing potential strong winds and heavy rainfall near the East Coast from Arthur. A brief period of below normal temperatures, with minimums around -10°F, is expected early Saturday, followed by a return to warmer air after the weekend. The cold front may lead to several days of convection with locally heavy rainfall in the Northern Tier, Central Plains, Ohio Valley, and Northeast. Very warm to hot conditions are likely in the Northern High Plains on Saturday and the North-Central Plains on Sunday, with overall above normal temperatures for the Western CONUS.

The latest models suggest a moderation of amplitude extremes, indicating a persistent mean pattern. Typhoon Neoguri's impact remains uncertain, while a compact upper low over the Alaska Peninsula shows discrepancies among models.
From Wednesday to Friday, expect the highest rainfall totals across the Mid-Atlantic and South, especially with diurnal convection in Florida bringing locally heavy rainfall. Cool high pressure will provide pleasant weather in the Midwest and Northeast before the front lifts northward. A southeastern-moving front from the northern plains may bring showers and thunderstorms.

day_2_weather_forecast: Heat wave conditions expected across much of the interior Northwest, with highs ranging from the 90s to over 100 degrees in Idaho and neighboring states. Monsoonal moisture, with precipitable water values of 1.0-1.25 inches, will bring an increased likelihood of thunderstorms and dry lightning in the Great Basin and Northwest. A series of reinforcing fronts will provide a mild airmass over the northern and eastern U.S., with temperatures at 850 mb potentially dropping to 2-3 degrees Celsius over the Great Lakes. This may lead to a notable cool outbreak mid-July, with clusters of ensemble members suggesting possible record low temperatures. Days 4-5 expect concentrated thunderstorms across the central plains due to low-level moisture transport and mid-level ascent.
