Aikyam-Lab/Synoptic-Bench huggingface dataset:
(Today and tonight) Extensive mid and upper level cloud cover will stream across the area today, ahead of an approaching upper level low that is currently centered over northern Mexico/southern California. As the aforementioned upper level low approaches the region from the west overnight, a Pacific front will track across the region late tonight into Tuesday morning. The current track of the low should keep the heavier rainfall to our north and east, and the rapid movement of the aforementioned front should limit rainfall totals. The highest rain chances overnight will be from the Concho Valley north into the Big Country, with rain chances gradually decreasing as you head south. South winds are forecast to increase to 15 to 25 mph, with higher gusts, by mid to late this evening, ahead of the approaching upper level low.
Models have upper ridging over the CWA today. An upper closed low, now centered over southern California, is progged to move east- northeastward into the Oklahoma panhandle by 12Z Tuesday morning. The only non-alpine pops with this will be "slight chance"s for snow over the Palmer Ridge late evening and overnight. 0 C warmer than yesterday's readings. On Tuesday morning the closed upper low moves rapidly into Kansas with weak ridging aloft transitioning over Colorado. Some of the higher resolution models showing wind gusts 65-75kt per RUC/HRRR guidance but feel this may be a bit too high.
309 AM CST Mon Feb 13 2023 Weak upper level trough was moving through the dvn cwa early this morning. A weak cold front has also moved through the cwa with temperatures in the upper 20s to upper 30s, with light west to northwest winds. Details: Today: Wall-to-wall sunshine expected today with a very dry airmass in place, as a ridge of high pressure moves across the cwa. This due to the potent closed upper low in the Desert Southwest that will be ejected northeast into the southern Plains. With high pressure situated in the northern Gulf of Mexico this is blocking any gulf moisture from returning northward.
For today s/w ridge builds across the region with mild temperatures in tow.
935 AM EST Mon Feb 13 2023 We will see a break from the rain through mid-week with high pressure in control.
757 AM EST Mon Feb 13 2023 Dry conditions will continue before widespread rain chances return with passing low pressure late in the week.
Water vapor and upper air analysis shows spit flow over the western Conus, with ridging over the northwest and a closed low stagnant over California. Ridge in the northwest will slide over the northern plains today, coupled with southwesterly surface winds, resulting in highs in the upper 40s and 50s today, with potential for some areas to see low 60s. As we progress through today, the closed low over CA ejects towards the central plains, setting the stage for our active mid- week weather. Have opted for a Winter Weather Watch for the time being in the higher impact areas, with a winter advisory for northwest South Dakota.
Dry and cooler weather is expected behind the system mid to late week with a slow warming trend during the weekend. Short wave ridge remains over NoCal for one last day with mild high temperatures in the mid and upper 60's over the Valley. Short term ensembles are in good agreement with Pac NW trough "inside slider" dropping south into the Great Basin Region Tuesday. This will bring cooler conditions and the chance for some very light precipitation over the high Sierra and southern Cascades.
940 AM EST Mon Feb 13 2023 Dry weather is expected today and tonight as a weak trough pushes into high pressure.
451 AM PST Mon Feb 13 2023 Showers will end early this morning as a low pressure system over Arizona moves east today.

H5 analysis from earlier this evening had a closed low over southeastern North Carolina. A trough extended south of this feature toward northern portions of the Bahamas. Across the southwestern CONUS, a closed low was located south of San Diego California. North of this feature, a trough of low pressure was located along the west coast of British Columbia. At the surface tonight, weak high pressure was located over western Kansas. Some wet snow may mix in with the rainfall along the highway 83 corridor Tuesday.
540 AM CST Mon Feb 13 2023 (Today through Tuesday) High clouds have begun to push into S TX this morning as a low pressure system approaches the state from the SW CONUS. Expect cloud cover to increase through the afternoon and evening hours as the low gets closer to the area. In addition to increasing cloud cover, the approaching low pressure will cause the pressure gradient to tighten, resulting in gusty winds. There is a slight (~20%) chance of showers over the Victoria Crossroads Monday night ahead of an incoming Pacific front associated with the exiting low pressure. Highs for Tuesday will be warmer as temperatures reach into the upper 70s to low 80s further west.
635 AM EST Mon Feb 13 2023 Dry weather is expected today and tonight as a weak trough pushes into high pressure.
A cold front will move across the region this morning from northwest to southeast. Tuesday, the cooler air aloft will become unstable due to the day time heating causing some snow showers.
The deep upper low that tracked across the Gulf States the last few days is now over the Atlantic Ocean and riding up the East Coast.
324 AM CST Mon Feb 13 2023 H5 analysis from earlier this evening had a closed low over southeastern North Carolina. A trough extended south of this feature toward northern portions of the Bahamas. Across the southwestern CONUS, a closed low was located south of San Diego California. North of this feature, a trough of low pressure was located along the west coast of British Columbia. At the surface tonight, weak high pressure was located over western Kansas. Some wet snow may mix in with the rainfall along the highway 83 corridor Tuesday.
(Today through Tuesday) Yesterday's low pressure system has moved up the coast and is now offshore just east of the DELMARVA peninsula. A high pressure center is over the central GOMEX. This high pressure will be the main weather-maker for the CWA through the remainder of the short term period.
Weak upper level trough was moving through the dvn cwa early this morning. A weak cold front has also moved through the cwa with temperatures in the upper 20s to upper 30s, with light west to northwest winds. Details: Today: Wall-to-wall sunshine expected today with a very dry airmass in place, as a ridge of high pressure moves across the cwa. This due to the potent closed upper low in the Desert Southwest that will be ejected northeast into the southern Plains. With high pressure situated in the northern Gulf of Mexico this is blocking any gulf moisture from returning northward.
This has resulted in quite the range in predawn temps, with 30s/40s common, and a few lower 50s in the higher terrain.
High pressure continues to build into the region, leading to a sunny start to the work week. (Today and tonight) High pressure will build over the region today as the weekend system exits the Mid-Atlantic coast this morning.
A deep upper level low currently situated over Arizona, will continue to move east, impacting our area tonight and tomorrow. The higher end amounts are expected primarily in the northern Big Country. As the low continues to move northeast of us, we will see a tightening of the pressure gradient at the surface on Tuesday. Winds behind the front will be westerly/southwesterly, which will allow for downsloping winds and warmer and drier conditions on Tuesday. The drier and warmer conditions mixed with the increase in wind speeds, will cause fire weather concerns tomorrow.
123 PM EST Mon Feb 13 2023 Dry conditions will continue before widespread rain chances return with passing low pressure late in the week. High pressure will slowly slide off to the east through the day on Tuesday as a weakened trough advects from the the west with an increasing gradient in southwest flow. The lower levels will finally saturate by Tuesday night with scattered showers passing through.

(Tomorrow through Monday) Upper low quickly lifts from SW KS to Iowa during the day Tuesday with the attendant cold front sweeping quickly eastward across the forecast area.
A cold front is still on track to move through our area today. At 9 AM MST the surface cold front extended from southwest to northeast Oregon and into the Idaho Panhandle. The front will contain snow (mixed with rain initially at the lowest elevations) and gusty winds. Snow amounts through Tuesday morning of 2 to 4 inches are expected in mountain valleys, with higher amounts in favored upslope ridgelines. A few snow showers will continue in the lower elevations overnight, but accumulations should be minimal with less than an inch expected.

Key Message over the next 36 hours will be precipitation chances Tonight and Tuesday HREF and CAMS this morning agree with convection developing ahead of an upper level trough/low that will lift northeast from New Mexico into Central Kansas late today and Tuesday. Ahead of this upper level trough early tonight 700-500mb lapse rates are forecast to be greater than 7C/km with improving 850-700mb moisture transport developing. As this upper level low/trough crosses into Central Kansas on Tuesday the main area of widespread precipitation will end from west to east as gusty northwest winds at 20 to 30 mph develop. Some wrap around moisture/precipitation will also be possible near the 700-500mb deformation zone west/northwest of this upper low.
(This evening through Tuesday Night) Departing upper-level ridge to maintain dry conditions through tonight. Moisture trapped beneath the diurnal ridge tonight will allow for widespread low clouds areawide by daybreak and continuing through much of Tuesday. Overnight low temperatures forecast to average in the low to mid 50s.
1156 AM CST Mon Feb 13 2023 (Today through Tuesday) High clouds have begun to push into S TX this morning as a low pressure system approaches the state from the SW CONUS. Expect cloud cover to increase through the afternoon and evening hours as the low gets closer to the area. In addition to increasing cloud cover, the approaching low pressure will cause the pressure gradient to tighten, resulting in gusty winds. There is a slight (~20%) chance of showers over the Victoria Crossroads Monday night ahead of an incoming Pacific front associated with the exiting low pressure. Highs for Tuesday will be warmer as temperatures reach into the upper 70s to low 80s further west.

405 PM CST Mon Feb 13 2023 (Issued 405 PM CST Mon Feb 13 2023) Tonight through Tuesday night: Low pressure tracking from the Plains to northwest WI tonight through Tuesday night. The closed upper low will be weakening as it lifts into the Upper Great Lakes. Total precip amounts are on the light side, around a quarter inch, due to mid level dry air moving into the area on a pseudo dry slot as the low passes to our north. There is a small possibility of a few rumbles of thunder Tuesday evening due to steep mid level lapse rates as the upper low goes overhead.
The short-term forecast has stayed the same over the past several days, with cyclonic flow slowly moving east of the Florida Keys and high pressure sliding in behind the departed cyclonic flow. The low stratus clouds, prevalent across the island chain community, have begun to dissipate this afternoon, leaving mostly clear skies. The clearing skies and decreasing breezes will set the stage for some radiational cooling tonight, with overnight night temperatures in the lower to middle 60s.
Several inches of snow will subsequently develop across ridges and mountains, while small hail showers and a few embedded thunderstorms occur mainly near the coast of Humboldt and Del Norte Counties.
553 PM CST Mon Feb 13 2023 Strong winds and rain return to the Mid-South tomorrow as a low pressure system moves across the region.
701 PM EST Mon Feb 13 2023 Quiet weather expected through the week as a high pressure system dominates.
A cold front continues to move through the Northern Rockies this afternoon, bringing scattered snow showers and gusty westerly winds to the region. Cooler air and insufficient solar heating should allow for snow to accumulate on paved surfaces. The second feature is a polar cold front moving into the region from the northeast tonight and Tuesday. The cooler air associated with this second front should help wet and slushy roads to freeze up overnight. This area of enhancement could bring significant snowfall over the higher terrain and around Gilmore Summit. A ridge of high pressure will be building over the Northern Rockies for the latter part of the work week.
Bands of precipitation have been rotating around this closed low during the day. Therefore, the current Winter Weather Advisory looks on track for the southern San Juan mountains with 4-8 inches of additional accumulations expected over the higher elevations. The next storm system will move southeast across the Great Basin as an elongated positively-tilted trough on Tuesday before closing off over southern Utah by Tuesday night.

A strong cold front has moved through the remainder of the CWA this evening, bringing wind gusts to 50 mph in some areas, and also bringing more snow than expected to some lower elevation areas.
The records for Feb 14 are at the lower end of the range compared to other dates during this week so are a little easier to achieve.
It will still be partly cloudy on Wednesday as the warm front waffles to the south. Went on the warmer side of guidance and expect BNA to be at least 74 degrees.
Water vapor movie loops show a potent trough in the southern Plains with excellent diffluence aloft. The gulf was starting to open with dewpoints in the lower 60s in se TX. Also the start of the high winds has been delayed to about noon which is when the advisory begins, and lasts to about 3 am Wed. Details: Today and tonight: Intense cyclone (985 mb) to track from the TX Panhandle to western IA to northern WI. As the cyclone lifts northeast away from our area, the rain will end from south to north tonight, along with gradually decreasing winds late tonight.
Stacked ridging over the region to keep the moderating trend going with temps warming to above normal this afternoon under mostly sunny skies but dew points will remain low today with pleasant afternoon RHs in the 20-30% range areawide.
Some strong to severe thunderstorms are possible tomorrow afternoon into the evening hours as an upper level low and attendant cold front moves across the region.
However any roads and walkways that are still wet will likely ice up as temperatures quickly drop below freezing shortly after dark. Even most areas at the coast will be below freezing. Wednesday will be dry with upper ridging building into the area.
