Aikyam-Lab/Synoptic-Bench huggingface dataset:
Current temps have fallen into predom the lower 30s/near 30F for most spots, as a large dome of high pressure builds further east into the Great Lakes/upper Midwest states. With a continued influx of cooler air out of the north along with dew pts in the lower/mid 20s, lows into early Sun look to fall into the lower 20s/near 20F, under continued clear skies.
611 PM CST Sat Dec 21 2024 - Sunday will be warmer and dry with high temperatures ranging from the freezing mark near the Highway 14 corridor to the mid 40s along the Missouri River.
852 PM CST Sat Dec 21 2024 - There is a low (15-25%) chance of a light wintry mix of precipitation, including rain and freezing rain over north central South Dakota Sunday morning into early Sunday afternoon, and freezing rain/sleet, or snow over northeastern SD into west central MN Sunday afternoon through early Sunday night. Portions of the west-river counties in this CWA are nosing up into the low 40s. Everything hinges on surface temperatures Sunday morning through Sunday evening, whether or not anything reaches the ground as plain rain or freezing rain/sleet. Again, low forecaster confidence in anything hazardous coming from this lower-bound PoPs potential Sunday/Sunday night.
Temperatures have dropped off slightly this evening as the weak cold front pushes east this evening. There is a low chance (<15% chance) of freezing rain briefly near Caldwell-Ontario in the morning with the push of warm air in the late morning. Other than temperatures being updated to reflect cooler temperatures this evening, forecast is on track. Light valley rain/mountain snow along a cold front tomorrow morning.
534 PM CST Sat Dec 21 2024 - There is a low (15-25%) chance of a light wintry mix of precipitation, including rain and freezing rain over north central South Dakota Sunday morning into early Sunday afternoon, and freezing rain/sleet, or snow over northeastern SD into west central MN Sunday afternoon through early Sunday night. Portions of the west-river counties in this CWA are nosing up into the low 40s. Everything hinges on surface temperatures Sunday morning through Sunday evening, whether or not anything reaches the ground as plain rain or freezing rain/sleet. Again, low forecaster confidence in anything hazardous coming from this lower-bound PoPs potential Sunday/Sunday night.
(Today and tonight) High pressure over New England will promote northeasterly flow today with mainly sunny skies expected again. Highs will still be on the cool side, ranging from the mid-50s across southeast Alabama and southwest Georgia to the lower 60s in the southeast Big Bend. Thus, have trended a bit warmer for lows tonight with upper 30s to lower 40s east of the Flint and Apalachicola Rivers with lower to middle 30s farther west where winds may go calm and skies remain mainly clear for most of the night.
233 AM EST Sun Dec 22 2024 High pressure covered much of the eastern United States this morning along with below normal temperatures. This high will move east today and offshore tonight with slowly moderating temperatures.
Patchy freezing drizzle is also possible over mainly north central and central Wisconsin Sunday night. Tonight and Sunday High pressure has kept most of the area dry today, however north winds had created a few bands of light lake effect snow impacting mainly the Door peninsula, but some flurries were observed as far south as Green Bay. This snow will come to an end in the next couple hours as the high moves east and winds gradually shift to the south. With southerly return flow starting to kick in Sunday, highs will be a little warmer, in the mid 20s to low 30s.
With winds becoming southeast, temperatures to gradually warm areawide with highs today in the mid to upper 60s and above freezing overnight lows tonight in the mid 30s to mid 40s. On Monday, warming trend to continue with afternoon highs in the in the low to mid 60s areawide. Additionally, near zonal flow aloft ahead of an approaching trough across west Texas will allow for enough instability to support elevated isolated convection across southeast Oklahoma and northeast Texas by late Monday afternoon.
339 AM EST Sun Dec 22 2024 Arctic high pressure will build across the region today.
108 AM EST Sun Dec 22 2024 Dry through Monday under high pressure, with a milder afternoon on Monday.
1125 PM CST Sat Dec 21 2024 (Tonight through Monday night) High pressure to our north has given us clear skies, cool temperatures, and low relative humidities. Besides some prescribed burns, there have been several reports of small fires thanks to the low humidity today. Tomorrow, the high pressure to our north will shift to the east, and our winds will turn to come out of the east.
1244 AM EST Sun Dec 22 2024 High pressure will lead to dry but cold conditions through the weekend. With the low level flow backing more westerly clouds to decrease overnight - leading to clearing skies. A low pressure system will move through the Great Lakes on Monday into Monday night. While the Ohio Valley is southeast of the low on Monday, breezy southwesterly flow will allow temperatures to moderate into the middle 40s south of I-70 to near 40 north of I-70. On Monday night, a cold front associated with the low moves through the Ohio Valley bringing a chance for rain. QPF remains on the low side since forcing is not lined up well with PWATs.
(Today through Monday) Broad upper trough along the Atlantic Coast, with ridging extending from Baja California to eastern Montana. At the surface, high pressure was centered over the Great Lakes with the axis of a southward extension of that high over the Lower Mississippi River Valley. As the axis of the high pressure shifts to the east of the area later today, winds will gradually become easterly by late in the day, and then southeasterly on Monday.
351 AM EST Sun Dec 22 2024 High pressure will continue to expand across the area today as the system drifts toward the East Coast. A low pressure system will enter the Great Lakes region for Monday and extend a weak cold front across the area on Monday night.
(Today) A clear/cold start early morning across the Tennessee Valley, with high pressure in control and a modified arctic air mass in place.
1052 PM CST Sat Dec 21 2024 - Sunday will be warmer and dry with high temperatures ranging from the freezing mark near the Highway 14 corridor to the mid 40s along the Missouri River.
1045 PM CST Sat Dec 21 2024 - Potential for light snow and/or freezing drizzle late Sunday night into Monday morning. Amounts look to be minimal, but the morning commute may be affected if freezing drizzle does occur.
Upper level forcing in advance of an upper trough will lead to precipitation chances of up to 80% across all except the southernmost part of the forecast area today, although individual showers will remain scattered. Things get quiet for a few hours this afternoon and evening before the trough itself passes to the north and kicks off a second round of showers into Monday morning. Precipitation from this round of showers remains further to the north, with the highest POPs (up to 80%) remaining north of I-80 and the southern half of the forecast area expected to remain almost entirely dry (POPs <15%). Precipitation looks to end by Monday morning as a brief ridging pattern sets up. QPF totals will be a tenth of an inch or less in the valleys and the highest elevations receiving up to half an inch.
206 AM CST Sun Dec 22 2024 - Low chance (20%) of freezing drizzle north and east late tonight into early Monday.
1056 PM CST Sat Dec 21 2024 (Tonight through Sunday night) Key Messages: - Increasing clouds and slightly warmer, but still pleasant temperatures. A weak easterly surface flow, and an increasing southerly low level flow overhead tonight, will usher moisture and warmer temperatures back across S TX.
With high pressure to our north, a notable MSLP gradient has also remained in place. Slightly warmer Sunday but still several degrees below normal. For tonight and Sunday the clouds should keep decreasing into the evening and then become mostly clear as high pressure builds southeast from the upper Midwest and western Great Lakes. Sunday highs will be a few degrees warmer and with lighter winds.
- A warming trend will occur this week with highs in the lower to mid 30s by Christmas. They will not fall much tonight, though, as WAA occurs ahead of an approaching mid-level trough. This precip advances east, ahead of the trough, into WI Monday morning before exiting our CWA by around noon. Examining GFS and NAM forecast soundings shows that at minimum we could see freezing drizzle, as the thermal profile is saturated from the surface to about 800 hPa within subfreezing temperatures. But, being this will occur Monday morning and at least some freezing drizzle seems possible, it will have a good chance at making a potentially hazardous commute.
High pressure will remain over the region tonight which will lead to good radiational cooling conditions, so have gone a little cooler than most guidance for min temps tonight. Temps Should bottom out near the freezing mark for roughly the NE half of the forecast area. The axis of the high pressure will move east of SE Texas tomorrow allowing for southeast flow to return with a gradual increase in low level moisture as well. Expect a few high clouds tomorrow and max temps about 5 degrees warmer as compared to today. Tomorrow night we will see min temps 10 to 15 degrees warmer with the potential of some patchy inland fog early Monday morning across west/southwest areas.
259 AM CST Sun Dec 22 2024 - Very light precipitation remains possible (<20%) near highway 14 and then into southwest MN near and east of the Buffalo Ridge tonight.
- A mix of light freezing drizzle and snow is possible later Sunday night into Monday morning, with a transition to light snow and rain by the afternoon. CMiller Issued 304 AM CST Sat Dec 21 2024 Tonight through Sunday: High pressure overhead this afternoon will continue to shift eastward tonight into Sunday, as low pressure approaches from the west.
316 AM EST Sun Dec 22 2024 Strong Canadian high pressure builds in through Monday, with dry and very cold conditions.
1243 AM EST Sun Dec 22 2024 Cold air will continue to filter into the area over the next couple of days high pressure remains in control of the area.
1206 AM EST Sun Dec 22 2024 (Through Sunday) A cool airmass will remain over the region tonight through tomorrow as a ridge of high pressure settles in across all levels. Another night of near or just below freezing appears quite likely as a favorable radiational cooling pattern persists, particularly across our SW GA and SE AL counties. Low temperatures this evening will generally remain in the upper 20s to low 30s inland with our usual cold spots across SE AL and SW GA seeing the lower end of that range. Chances aren't the greatest at only 10% to 20%, but it signifies the start of warmer weather returning as we head into Christmas.
Will keep the Min temp fcst as is, featuring zero to -5 north and east of GRR and 10 to 15 to the south and west but the location/movement of the stubborn lake strato-cu may lead to warmer readings. One other thing to watch out for is for a little bit of light icing, mainly across the far southern counties as the air aloft will be warm enough for some rain, but the sfc stays below freezing until mid-afternoon.
1130 PM CST Sat Dec 21 2024 - There is a low (15-25%) chance of a light wintry mix of precipitation, including rain and freezing rain over north central South Dakota Sunday morning into early Sunday afternoon, and freezing rain/sleet, or snow over northeastern SD into west central MN Sunday afternoon through early Sunday night.
1227 AM EST Sun Dec 22 2024 * Cold overnight with lows in the low 20s and teens Sunday morning.
(Today through Monday) Model consensus keeps broad high pressure in place across the region with relatively dry and cooler air persisting over SoFlo today. Meanwhile, ensembles and global solutions depict a trough/low complex moving away from the NE CONUS. But the more tangible difference will be felt tonight when overnight lows should remain 8-10 degrees warmer than the previous night (staying in the upper 50s to mid 60s).
Sunday will be sunny and cool with highs in the low to mid 40s. For those of you who are doing some last minute Christmas shopping (looking at myself), bundle up out there! (Rest of today through Sunday) An overcast morning will make way for a little sunshine this afternoon as low to mid level clouds push on out ahead of building high pressure to our NW. Temperatures fall into the low 20s tonight, upper teens across the Plateau, with the decreased cloud cover. Sunday will be a pretty quiet weather day with sunny and dry conditions and slightly warmer temperatures.
1013 PM EST Sat Dec 21 2024 High pressure will lead to dry but cold conditions through the weekend. With the low level flow backing more westerly clouds to decrease overnight - leading to clearing skies. A low pressure system will move through the Great Lakes on Monday into Monday night. While the Ohio Valley is southeast of the low on Monday, breezy southwesterly flow will allow temperatures to moderate into the middle 40s south of I-70 to near 40 north of I-70. On Monday night, a cold front associated with the low moves through the Ohio Valley bringing a chance for rain. QPF remains on the low side since forcing is not lined up well with PWATs.
High pressure is expected to remain over the Central CONUS tomorrow bringing dry conditions and above normal temperatures similar to what the western half of the forecast area saw today. Temperatures are expected to warm into the low to mid 60s with northwest winds around 10 mph. The north winds will help move a colder air mass over the region bringing Monday's high temperatures into the low to middle 50s.
302 AM EST Sun Dec 22 2024 Cold, dry air will remain into Monday as Arctic high pressure moves across the eastern U. The high will move offshore late Monday as a coastal trough develops off the Southeast Coast.
150 AM EST Sun Dec 22 2024 Arctic high pressure centered over southern Ontario will extend southward into North Carolina as it drifts over the Northeast and Mid Atlantic states through early Monday. The high will weaken and push offshore late Monday, allowing for gradually warming temperatures through mid week. As of Monday morning, high pressure is forecast to be sitting over New York with a ridge extending southwest into the Carolinas.
1101 PM CST Sat Dec 21 2024 High pressure remains dominate across the CWA tonight. Temperatures are quickly falling with many already approaching freezing. Given the enhanced cooling in play, elected to make temperatures a few degrees cooler across the CWA overnight, with many expected to fall into the mid to upper 20's, and low 30's. Sunday will remain mostly cool across the region, with temperatures ranging from the lower to upper 50s, perhaps some lower 60s across some of our southern zones. Sunday night will be slightly warmer than tonight, with lows ranging from the mid 30s to mid 40s.
This high cloud cover will persist through the day today with a fairly large blanket of high clouds still incoming well offshore.
- Slightly cooler, with considerable clouds Monday.
1111 PM CST Sat Dec 21 2024 Latest surface analysis places a 1036 mb ridge of high pressure over Ontario.
1224 AM EST Sun Dec 22 2024 Dry through Monday under high pressure, with a milder afternoon on Monday.
149 AM MST Sun Dec 22 2024 KEY MESSAGES: - Freezing rain expected through this afternoon. WEATHER PATTERN OVERVIEW: A warm upper ridge will be the main weather player through early this week making for warm temperatures (especially just off the surface). This temperature profile, colder sub freezing temps at the surface with warm temps aloft (close to 5C at ~2k feet agl) will set the stage for a freezing rain event starting in the west around 09z this morning as a disturbance passes through the upper ridge. The threat for FZRA tapers as temps warm above freezing in the mid-afternoon. High pressure ridging will return tonight, resulting in a warm and dry day Monday. The upper ridge flattens somewhat on Christmas Day with another disturbance pushing through, however with this disturbance most of the energy stays well to the south.
1022 PM CST Sat Dec 21 2024 High pressure remains dominate across the CWA tonight. Temperatures are quickly falling with many already approaching freezing. Given the enhanced cooling in play, elected to make temperatures a few degrees cooler across the CWA overnight, with many expected to fall into the mid to upper 20's, and low 30's. Sunday will remain mostly cool across the region, with temperatures ranging from the lower to upper 50s, perhaps some lower 60s across some of our southern zones. Sunday night will be slightly warmer than tonight, with lows ranging from the mid 30s to mid 40s.
Lastly, temperatures are about 3 to 7 degrees cooler than this hour last night.
Temperatures will rebound nicely this afternoon with highs warming into the middle 60s for the Nature Coast and into the lower 70s south of I-4. Moving forward into the holiday week, as high pressure builds over the region temperatures will continue to tick upward, with above average temperatures expected to begin the week once again.
506 AM CST Sun Dec 22 2024 (Today) A clear/cold start early morning across the Tennessee Valley, with high pressure in control and a modified arctic air mass in place.
932 AM EST Sun Dec 22 2024 Dry through Monday under high pressure, with a milder afternoon on Monday.
431 AM EST Sun Dec 22 2024 High pressure will build in from the west today and tonight and crest over the area Monday.
622 AM EST Sun Dec 22 2024 Cold, dry air will remain into Monday as Arctic high pressure moves across the eastern U. The high will move offshore late Monday as a coastal trough develops off the Southeast Coast.
709 AM EST Sun Dec 22 2024 High pressure covered much of the eastern United States this morning along with below normal temperatures. This high will move east today and offshore tonight with slowly moderating temperatures.
633 AM EST Sun Dec 22 2024 High pressure covered much of the eastern United States this morning along with below normal temperatures. This high will move east today and offshore tonight with slowly moderating temperatures.
There will be a chance for periods of light freezing rain on Monday morning, primarily focused on the Bitterroot and Flathead valleys.
(This evening through Wednesday) Expect warm and dry conditions during the next 24 hours as a strong upper level ridge continues to the dominate our weather.
Updated at 135 AM EDT Wed Oct 15 2025 - Dry weather and seasonal temperatures will continue for the rest of the week with Thursday night being cooler than what has been seen the past several nights.
The amount of effective radiation cooling will be dependent how much the stratus deck clears out to drop temperatures below freezing. Temperatures are expected to drop down to the low-30s to the upper 20s, with colder temps expected in the Ellensburg region along with any other low lying sheltered valley's. A mid-level low pressure system situated in California, will continue to push eastwards leaving minimal weather impacts as is makes it way through the Nevada/Idaho/Wyoming region. Our next weather maker will be through the weekend, as a trough digs through the Gulf of Alaska, into the PacNW region.
Road and surface air temperatures are likely to stay near or above freezing in areas where drizzle occurs overnight, but this will also need to be monitored.
232 AM MDT Wed Oct 15 2025 - Dense fog/patchy drizzle this morning, but patchy/areas of fog will linger through tonight - Unsettled through Thursday - Isolated strong/severe thunderstorms tonight parts of northeastern WY/southwestern SD - Drying out this weekend with seasonal weather 08z surface analysis had high over the Great Lakes and trough from eastern MT into central CO. Forecast concern continues to be upper low. Today/tonight, upper low ejects into the central Rockies. Thursday, upper low moves into southern MB with dry slot over the eastern half of the area.
(Today and tonight) High pressure will continue across the region today.
133 AM EDT Wed Oct 15 2025 Weak high pressure will extend across the southern Appalachians and Carolinas ahead of a moisture-starved, backdoor cold front that will move south through the area tonight.
450 AM EDT Wed Oct 15 2025 A cold front will pass today, with high pressure then in control through the weekend.
It won't take much for temperatures to fall into the low 40s (lows tonight). The low will move over our north central SD counties by 18Z Thursday and exit across ND while dragging a cold front over the rest of the forecast area during the afternoon and evening hours. Temperatures Thursday remain tricky with the cold front nearby, but we still have highs in the 70s over eastern SD/western MN with around a 5F spread in the 25- 75th percentiles off the NBM. The timing of the cold front and exiting low remains pretty consistent.
An area of low pressure that has been along the eastern seaboard the past few days has shifted farther east north of Bermuda. The associated cold front extends southwest over the Bahamas and across Cuba.
- Fog possible tonight ahead of a warm frontal passage, could be locally dense especially along and north of I-80. - A cold front moves through the area Thursday night bringing the next chance (20-50%) for showers and thunderstorms.
353 AM EDT Wed Oct 15 2025 High pressure builds in today and will anchor over the Eastern Seaboard into this weekend.
Cooler temperatures will be in place through the end of the week and the next chance for rainfall will be this weekend, as a strong system moves through the Ohio Valley region.
114 AM CDT Wed Oct 15 2025 - High pressure keeps us dry and seasonally mild for the rest of the work week.
The primary driver of our forecast through the rest of the week will be a ridge of high pressure. This will keep us generally quiet, though an inverted trough will ride along the south periphery of the ridge and into the lower to mid Texas coast. Unfortunately, moisture associated with this inverted trough remains minimal into South Texas and confined to the near surface layer and will not give us much in the way of rain chances. By the end of the week the ridge shifts eastward as a larger trough moves into the central part of the country. This will allow a cold front to at least approach the area late in the weekend.
Another quiet day expected across the region with just some scattered to possibly broken clouds later this morning and afternoon as a weak backdoor cold front moves in from the northeast. An area of low pressure that has been along the eastern seaboard the past few days has shifted farther east north of Bermuda. The associated cold front extends southwest over the Bahamas and across Cuba.
1050 AM EDT Wed Oct 15 2025 High pressure will build through Wednesday leading to a warming trend. A passing dry cold front Wednesday night will usher in the coolest air since Spring.
- Scattered showers/storms possible (20-60%) Thursday evening- night as a cold front moves through the area.
- Meteorological Overview: An elongated mid-level trough is now approaching the Northern Rockies from the west/southwest while local observations log another morning with low stratus, patchy fog, and scattered areas of light rain/snow. A closed low over the Great Basin is still expected to trek northeastward into eastern MT by Thursday evening.
1029 AM EDT Wed Oct 15 2025 A cold front will pass today followed by high pressure in control through the weekend.
