Aikyam-Lab/Synoptic-Bench huggingface dataset:
A closed low is currently situated across the north central Gulf and churning eastward. Going into Tuesday, mid-level ridging will become positioned across the Central CONUS, resulting in the return of dry northwest flow back into the region.
1107 AM CST Mon Feb 5 2024 (Rest of Today) Tranquil weather across the Tennessee Valley this morning in wake of a departing low pressure system. In response to the sunshine, expect highs to continue climbing back into the low to mid 60s by this afternoon.
207 PM EST Mon Feb 5 2024 High pressure will maintain dry weather and above average temperatures through much of the week.
Water vapor imagery highlights a potent mid-latitude cyclone stumbling southeast through the eastern Gulf of Mexico. Deep cyclonic flow, healthy boundary layer winds, and steep low and mid level lapse rates support scattered, low topped thunderstorms within the southeastern quadrant of the cyclone. However, a thundery squall just raced east-southeast through the Lower Keys this hour, and volumetric scans from KBYX radar suggest small hail and near-severe gusts are possible with this storm as well. The convection from this morning and the proximity of the low pressure system likely have delayed the gradient winds. The mid-latitude cyclone will pivot eastward tonight and Tuesday as higher heights spread east into the Mississippi River Valley. The low pressure system will broaden and deepen to near 990 mb as it nears Bermuda.
1148 AM CST Mon Feb 5 2024 - Medium confidence (50% chance) dense fog and freezing fog develop late tonight into Tuesday morning.
High pressure will strengthen across our area tonight. Aloft, heights will begin rise late at night as a final short wave rotates about he the upper low near the Canadian Maritimes as it moves eastward. Fair weather and moderating temperatures as high pressure dominates at the surface and aloft. While aloft ridging will build eastward and strengthen.
143 PM EST Mon Feb 5 2024 High pressure will maintain dry weather and above average temperatures through much of the week.
103 PM EST Mon Feb 5 2024 High pressure and a persistent ridge through most of this week will provide for fair weather and above normal temperatures that will top out at 20 degrees or more above average by mid to late week.
Winds will diminish later this afternoon as the gradient relaxes and the upper level ridge moves into south Texas. An upper- level ridge will begin moving into the region tonight with the ridge axis expected to be located across South Texas by tomorrow evening, which will allow for our winds to decrease. Cooler temperatures are expected today with highs struggling to break 70 degrees before warming back to more seasonal values tomorrow.
129 PM EST Mon Feb 5 2024 Dry and mild high pressure builds into the region, and dominates our weather through most of the work week.
This will be thanks to an expected mid to upper level ridge influencing the combined Panhandles through Wed and possibly the western fringe lingering through Fri.
1127 AM CST Mon Feb 5 2024 The nearly stacked low pressure system was noted on satellite imagery spinning over the northern Gulf just south of Pensacola Florida. The mid/upper level low responsible for this past weekend's rain, will continue to exit southeast and out of the region today. Breezy northerly winds now over the region will result in slightly cooler drier air advecting into the forecast area through the period. /19/ By Tuesday, drier air will filter into the region through mid-week as broad ridging allows for increased heights and above normal temperatures through the end of the week. Highs on Tuesday through the remainder of the period range from the lower 60s to lower 70s, while lows range from the upper 40s to middle 50s.
(Today through Tuesday) Both sfc and upper low are well off to our east early this morning over the northern Gulf Coast, but will continue to influence our weather locally through the morning with breezy northerly winds over portions of the area. Wrap-around moisture will keep some cloud cover over the east half of the area for much of today, and combined with the weak CAA we'll see high temperatures a touch cooler than average. Upper ridging to our west will amplify today and the axis should be overhead by sunrise Tuesday.
1112 AM CST Mon Feb 5 2024 Cool high pressure is building into the the region as the upper low near the Gulf Coast departs. It will be a bit cool for the next couple of mornings, especially Tuesday when much of the Midsouth will be in the low to middle 30s.
(This evening through Tuesday) A rather benign weather pattern is expected for this evening through tomorrow as an upper-level ridge is starting to build in across the region. A few low-lying locations could get close to freezing by sunrise. The high pressure center should move eastward by tomorrow afternoon and allow southeast winds to increase to 5 to 10 MPH. (Tuesday night through next Monday) The large upper trough currently aiding in the atmospheric river event over in California will continue to move east, with its axis moving onshore early Tuesday.
Guidance is advertising this low to continue to move south into mid afternoon, taking the clouds with it before moving in an eastward direction by tonight. Tonight as the system moves off, winds remain northerly, though the push of cooler air eases.
An inverted trough extends northeast from north Georgia across eastern Tennessee and into southwest Virginia. Highs in the lower 60s still look reasonable. Low afternoon RH due to the warmer temps and drier air. Temperatures are in the low/mid 30s where winds are calm and upper 40s where winds remain. This is due to drier air moving in from the north as a deep area of low pressure pushes further to our south. With above normal temps and drier air, expect afternoon min RH values to be on the low side and range from the mid 20s to mid 30s for most places.
(This evening through Tuesday) A rather benign weather pattern is expected for this evening through tomorrow as an upper-level ridge is starting to build in across the region. A few low-lying locations could get close to freezing by sunrise. The high pressure center should move eastward by tomorrow afternoon and allow southeast winds to increase to 5 to 10 MPH.
1148 AM CST Mon Feb 5 2024 (Today through Tuesday) The vertically stacked cold core upper low that brought thunder/hail to parts of the CWFA yesterday evening will continue to meander south and east today. That said, the frictional component of the cyclonic curvature in the low level pressure field should keep mostly overcast skies across the region. With the high pressure building in upstream, northerly or northeasterly winds will be breezy today and into the overnight. High pressure at the surface will begin to spread into the region, which should help lower winds and allow for the return of some sunshine. With the increase in insolation and increase in heights with the departing ULL, max temperatures on Tuesday should be roughly 10 degrees warmer than what is currently advertised for today for many locations.
320 PM EST Mon Feb 5 2024 High pressure will continue to provide fair weather with generally mild temperatures for early February.
1250 PM CST Mon Feb 5 2024 - Seasonally mild early week temperatures trend markedly warmer by the end of the week.
1030 AM EST Mon Feb 5 2024 High pressure will maintain dry weather and above average temperatures through much of the week.
/NEW/ /This afternoon through Tuesday night/ Subsidence associated with a building ridge aloft will continue to scatter out post-frontal stratus through the day, yielding a mostly sunny afternoon. Daytime heating will be offset by lingering low level cold air advection, keeping afternoon temperatures generally in the upper 50s to the lower 60s. The good news is that the fog should not be dense and temperatures will be above freezing so freezing fog is not expected.
215 PM EST Mon Feb 5 2024 High pressure and a persistent ridge through most of this week will provide for fair weather and above normal temperatures that will top out at 20 degrees or more above average by mid to late week.
1113 AM CST Mon Feb 5 2024 (Today and tonight) The stacked low pressure system that has produced wind across the forecast area the last couple of days has moved to the central Gulf Coast. However, a significant trough axis extends as far to the northwest as northwest Texas early this morning with significant low level cloud cover wrapping around the low in conjunction with the northwest extension of the trough. This is going to quickly change however, as the trough finally shifts well southward into the western Gulf of Mexico by noon and upper level ridging edges eastward across New Mexico. Cirrus will move in from the west as the mid/upper ridge axis moves eastward across the southern High Plains.
621 PM EST Mon Feb 5 2024 Dry and mild high pressure builds into the region, and dominates our weather through most of the work week.
A weakening area of low pressure will continue to bring light to moderate rainfall and high elevation snowfall through tonight.
635 PM EST Mon Feb 5 2024 (Through Tuesday) An upper low will continue sliding southeast through the near term resulting in northerly flow prevailing across the area. At the surface, low pressure will also slide southeast with northerly flow prevailing through the near term ushering in cool and dry continental air. As high pressure continues to fill in, drier air and subsidence aloft will erode the cloud deck tomorrow throughout the morning with clear skies in the forecast for the remainder of the day. Opted to side with MOS guidance this forecast cycle for the high temperatures tomorrow despite persistent cold air advection via northerly flow and nudged temperatures up a couple degrees across the board.
530 PM CST Mon Feb 5 2024 - Areas of Fog redeveloping after midnight east of highway 23 - Windy and warmer Tuesday.
- There is a 30% chance in light icing from freezing drizzle late this evening into Tuesday morning.
526 PM CST Mon Feb 5 2024 (This afternoon through Tuesday night) Ridging will move off to the east tonight and a short wave trough will be approaching the area from the west on Tuesday. Southwest upper level flow in advance of this trough along with southeast surface winds beginning this evening and continuing into tomorrow night will bring in more moisture and high clouds.
517 PM CST Mon Feb 5 2024 - Seasonally mild early week temperatures trend markedly warmer by the end of the week.
Cloudiness wrapping around the low currently extends across portions of southeast LA and southern MS but is steadily breaking up.
538 PM CST Mon Feb 5 2024 (This evening through Tuesday) A rather benign weather pattern is expected for this evening through tomorrow as an upper-level ridge is starting to build in across the region. A few low-lying locations could get close to freezing by sunrise. The high pressure center should move eastward by tomorrow afternoon and allow southeast winds to increase to 5 to 10 MPH. (Tuesday night through next Monday) The large upper trough currently aiding in the atmospheric river event over in California will continue to move east, with its axis moving onshore early Tuesday.
643 PM EST Mon Feb 5 2024 High pressure and a persistent ridge through most of this week will provide for fair weather and above normal temperatures that will top out at 20 degrees or more above average by mid to late week.
For tonight, the low will slowly move over the Atlantic, with rainfall coming to an end as winds shift to northerly and drier air starts to fill in. Rather erratic winds this evening (due to low pressure overhead) will eventually increase out of the north, with wind gusts to 25 knots or so through the rest of the period. Low pressure over the area will slowly move over the Atlantic tonight, with winds becoming northerly and increasing.
403 PM EST Mon Feb 5 2024 High pressure and a persistent ridge through most of this week will provide for fair weather and above normal temperatures that will top out at 20 degrees or more above average by mid to late week.
515 PM CST Mon Feb 5 2024 (This afternoon through Tuesday Night) Amazing day across Middle Tennessee for early February with sunny skies, temperatures in the low to mid 60s, and low RH. Gusty north winds up to 25 mph combined with the low RH has led to marginal fire danger conditions across the area, but this will rapidly improve after 23Z. After a chilly night tonight with lows around the freezing mark, tomorrow will be another nice albeit slightly cooler day with highs in the mid 50s to around 60. Lows look to drop back to around freezing Tuesday night.
928 PM EST Mon Feb 5 2024 High pressure and a persistent ridge through most of this week will provide for fair weather and above normal temperatures that will top out at 20 degrees or more above average by mid to late week.
305 PM CST Mon Feb 5 2024 - Areas of Fog redeveloping after midnight east of highway 23 - Windy and warmer Tuesday.
A trough has become stagnant over the region and is bringing weak, scattered showers across most of SW Oregon and NorCal. This parked trough will allow a cooler airmass to settle into the region, bringing subfreezing temperatures to NorCal and areas east of the Cascades. For the Oregon Counties west of the Cascades, temperatures are expected to remain above freezing and should the small chance of freezing temperatures occur, it would likely be short enough that refreezing is not a widespread concern. Part of what is not allowing the temperature to really plummet is the instability that remains from the trough overhead.
935 PM EST Mon Feb 5 2024 Dry and mild high pressure builds into the region, and dominates our weather through most of the work week.
518 PM CST Mon Feb 5 2024 (This evening through Tuesday) The last little bit of low stratus has finally burned off over the region as the upper level ridging has moved to just the west of the FA.
649 PM EST Mon Feb 5 2024 High pressure will continue to provide fair weather with generally mild temperatures for early February.
612 PM CST Mon Feb 5 2024 (This Evening and Tonight) With the low pressure system that brought us dense cloud cover and rain yesterday departing the area, clear conditions are now prevailing in most locations. Ample sunshine is helping to warm temperatures into the low to mid 60s in most locations as of early/mid afternoon, in spite of the light northeast flow.
814 PM EST Mon Feb 5 2024 A low pressure system off the east coast of Florida will track to the northeast. A period of dry weather follows with warmer temperatures expected towards the end of the week and into the weekend. Scattered showers are also possible this weekend as a cold front stalls across the region. Deep upper low centered near the west coast of FL this evening. Pressure ridge to the north and west of the region will slowly build southeast. A fairly tranquil short term is expected as the offshore weather system continues to move away from the region and is replaced by ridging currently over the Central CONUS.
644 PM EST Mon Feb 5 2024 A large ocean low pressure system will stay well east of the Gulf of Maine through tonight while high pressure settles across the Saint Lawrence River Valley. High pressure will then build toward the region Tuesday.
503 PM CST Mon Feb 5 2024 (This evening through Tuesday) With light winds and mostly clear skies tonight, radiational cooling will likely result in areas of fog toward morning (CAMs show the highest chances in parts of western Oklahoma).
A backdoor cold front continues to slowly sink south and eastward through northern and eastern New England this evening with GOES16 IR and water vapor both showing signs of its progression. Otherwise, somewhat breezy winds this evening will weaken under 5kts after 06 UTC or so and the incoming cooler air mass in the wake of the front will support temperatures becoming quite chilly by Tuesday A. High pressure will strengthen across our area tonight. Aloft, heights will begin rise late at night as a final short wave rotates about he the upper low near the Canadian Maritimes as it moves eastward. Fair weather and moderating temperatures as high pressure dominates at the surface and aloft. While aloft ridging will build eastward and strengthen.
612 PM EST Mon Feb 5 2024 High pressure will continue to provide fair weather with generally mild temperatures for early February.
949 PM EST Mon Feb 5 2024 A large low pressure system will stay well east of the Gulf of Maine through tonight while high pressure settles across the Saint Lawrence River Valley. High pressure will then build toward the region Tuesday.
147 AM MST Tue Feb 6 2024 146 AM MST Tue Feb 6 2024 - Unseasonably warm temperatures today - Fog returns tonight - System entering the plains Wednesday will bring cooler temperatures and chance for accumulating snow over portions of northeastern WY, northwestern SD, and the Black Hills. Current upper air analysis depicts messy central US ridge over the Northern Plains with southwesterly flow over the CWA. To our west, an upper level trough sits just off the Pacific coast. We'll stay under the influence of the ridge through today with temperatures well above average for this time of year. Longwave trough over the western US will continue to move eastward, bringing cooler weather into the region by Wednesday. At the sfc, leeside cyclone will deepen over WY/western NE through Wednesday afternoon.
1114 PM CST Mon Feb 5 2024 Today and Tonight: Mid afternoon water vapor imagery/RAP analysis showed the circulation around a nearly stacked low pressure system over the northeast Gulf of Mexico. This low pressure system will continue tracking southeast tonight across the Florida peninsula and over the western Atlantic ocean Tuesday. In addition, ridging surface and aloft will begin building into the region tonight and continue Tuesday. This will result in slightly cooler than normal temperatures tonight with morning lows back in the 30s at most locations and near 40F in the southeast. Despite the continued caa Tuesday, near full insolation Tuesday will help afternoon temperatures top out above normal in the low to mid 60s.
1255 AM EST Tue Feb 6 2024 A large low pressure system will stay well east of the Gulf of Maine through tonight while high pressure settles across the Saint Lawrence River Valley. High pressure will then build toward the region Tuesday.
320 AM EST Tue Feb 6 2024 High pressure over the region will linger through Wednesday night.
High temperatures under mostly clear skies will be around the low to mid 60s. Winds back off some tonight and with high pressure and clear skies filling into the region, we'll see cooler overnight lows in the mid to upper 30s.
1130 PM CST Mon Feb 5 2024 Skies are clear across the Mid-South this evening with temperatures ranging from the lower 40s to lower 50s. With clear skies, fairly light winds and a dry atmosphere; temperatures will fall into the low to mid 30s by Tuesday morning. ARS High pressure will bring quiet weather to the Mid-South through Wednesday.
Cloudiness wrapping around the low currently extends across portions of southeast LA and southern MS but is steadily breaking up. Global models depict a very amplified ridge extending from the Gulf of Mexico to Canada to track east across the mid section of the country. Glancing at MEX and ECX as well as just how expansive the ridge looks to be, decided to go with the 90th percentile NBM, which still may be too cool.
1026 PM EST Mon Feb 5 2024 High pressure will continue to provide fair weather with generally mild temperatures for early February.
1255 AM EST Tue Feb 6 2024 High pressure will continue to provide fair weather with generally mild temperatures for early February.
Lows will dip below freezing for many areas along and north of I-40 overnight tonight, with more scattered freezing temps south of I-40. Locations along and west of Highway 75 in northeast Oklahoma have the highest chances nearer the ridge axis and as temperatures cool well below crossover temps from dewpoints this afternoon.
1029 PM CST Mon Feb 5 2024 (This afternoon through Tuesday Night) Amazing day across Middle Tennessee for early February with sunny skies, temperatures in the low to mid 60s, and low RH. Gusty north winds up to 25 mph combined with the low RH has led to marginal fire danger conditions across the area, but this will rapidly improve after 23Z. After a chilly night tonight with lows around the freezing mark, tomorrow will be another nice albeit slightly cooler day with highs in the mid 50s to around 60. Lows look to drop back to around freezing Tuesday night.
1224 AM EST Tue Feb 6 2024 Dry and mild high pressure builds into the region, and dominates our weather through most of the work week.
Clear across the region as high pressure continues to build south out of Canada.
Winds are expected to strengthen into Tuesday as low pressure over the western Atlantic works to tighten the local pressure gradient.
1002 PM EST Mon Feb 5 2024 High pressure will continue to provide fair weather with generally mild temperatures for early February.
(Tonight) As high pressure continues to expand across the Midwest an into the Southeast, drier air will continue filtering into the region.
1032 PM CST Mon Feb 5 2024 (This afternoon through Tuesday night) Ridging will move off to the east tonight and a short wave trough will be approaching the area from the west on Tuesday. Southwest upper level flow in advance of this trough along with southeast surface winds beginning this evening and continuing into tomorrow night will bring in more moisture and high clouds.
951 PM MST Mon Feb 5 2024 1239 PM MST Mon Feb 5 2024 - Warm temperatures continue through mid-week - A system entering the northern plains Wednesday will bring cooler temperatures with chances for precipitation. Current Water Vapor and upper air models show long wave trough over the west coast, while upper ridge sits over the Northern Plains and Great Lakes regions, with northwest flow over our region. Ridging will continue to keep our highs well above normal for today and Tuesday. Temperatures begin to cool on Wednesday as the upper trough nears our region. Light south to southeasterly flow on Wednesday morning, may allow for some fog or freezing fog to develop out ahead of the system, however most models keep our temps around or just above freezing.
(Today through Wednesday) An upper level ridge extends from northeastern Mexico to the Great Lakes region and a deep trough is moving onto the west coast this morning. Temperatures are 5 to 15 degrees cooler than 24 hours ago in the upper 30s to middle 40s. The upper ridge will move slowly toward the east as the west coast trough pushes inland. Temperatures will warm today with highs around three to five degrees warmer than yesterday reaching near to above normal. High temperatures Wednesday will be another couple of degrees warmer.
909 PM CST Mon Feb 5 2024 Skies are clear across the Mid-South this evening with temperatures ranging from the lower 40s to lower 50s. With clear skies, fairly light winds and a dry atmosphere; temperatures will fall into the low to mid 30s by Tuesday morning. ARS High pressure will bring quiet weather to the Mid-South through Wednesday.
This feature is producing stratiform rain that is just barely reaching the Lower Keys.
- Windy and warmer Tuesday. More sun has been seen in the Garden City and Scott City area and west and southwest â seemingly reflected in the temperatures getting into the low 50s in those areas early this afternoon. The HREF mean visibility and HRRR are both showing potential for dense fog starting out around the DDC-Meade areas and spreading northeast after midnight basically to most of the highway 183 corridor (Hays and south) corridor before being eroded on south winds early Tuesday. The coming day Tuesday will be warmer than Today with more sun and southerly winds factoring into afternoon warming into the 60s.
