Aikyam-Lab/Synoptic-Bench huggingface dataset:
Low pressure off the Texas coast will be moving eastward and northeastward away from the area and will be replaced with high pressure building in from the north. For temperatures, expecting tonight's readings to bottom out into the mid to upper 30s north, around 40 central and in the low to mid 40s at the coast. With the clearing skies on Wednesday, look for high temperatures to reach the lower to mid 60s. Another cool night is in store for the area on Wednesday night with lows ranging from the upper 30s to lower 40s inland to the lower 50s at the beaches.
1201 PM CST Tue Mar 8 2022 (Today and tonight) Currently there is an upper level trough moving east into New Mexico. Ahead of this trough, subtropical moisture is streaming overhead in mid and upper level cloudiness, while at lower levels, moisture is also advecting northward into our area with low clouds developing and moving northward into our southern counties. As the upper level trough moves east, skies are expected to clear slowly from west to east. Tonight, with clear skies, and generally light and variable winds, freezing temperatures are expected area-wide with lows ranging from the mid 20s north of I-20 to near 30 degrees along our southern CWA border. Temperatures may drop into the low/mid 20s in some of our southern valley and low lying locations as well.
Lee trough will develop by tomorrow afternoon, with south to southeast winds returning, along with warmer temperatures. (Wednesday night through next Tuesday) All eyes still watching the next strong cold front and the chance for light wintry precipitation.
As we move into Wednesday evening and Wednesday night, large-scale forcing for ascent will increase as the mid/upper trough approaches bringing increasing chances for snow to northern and central KS. Our central KS counties are expected to be on the southern fringe of the higher snowfall totals where we could see 6-7 inches along and north of I-70.
The passage of the trough will shove a weak frontal boundary south tonight, shifting winds to the NNW for Wednesday. With plenty of sun, though, good mixing should allow temperatures to reach the low 50s for the southern part of the area despite weak cold advection.
219 PM CST Tue Mar 8 2022 Ample sunshine and southwest winds ahead of an approaching cold front have helped recover our temperatures quite impressively today. Overnight lows were in the single digits over portions of eastern Iowa, and mid teens in Illinois, and as of 2 PM, as snow cover melts away, temperatures range from the lower 30s north to around 40 in snow free areas. The cold front at 2 PM is located from near Sioux City Iowa to Minneapolis Minnesota.
Main cold front has pushed out of the FA leaving gusty winds out of the west- northwest in its wake. Moving into Wednesday, a cooler day is in store as CAA persists.
/Tonight through Wednesday Night/ The cold rain lingering across the Ark-La-Tex will gradually taper off after sunset, leaving dry but still cooler than average conditions in place through the middle of the week. Depending on where the cloud deck breaks up, temperatures will fall to at or below the freezing mark, especially north of the I-30 corridor. As troughing continues to shift east by Wednesday, northerly winds will gain a northeasterly component.
207 PM CST Tue Mar 8 2022 The northern portion of an upper level trough axis is currently centered over the Texas Panhandle and will continue to lift northeast overnight. Zonal flow aloft by early Wednesday morning will quickly evolve into another broadening trough across New Mexico and West Texas by early afternoon.
1042 AM MST Tue Mar 8 2022 The upper trough and associated surface cold front are swinging areas of light snow or flurries across the forecast area early this morning with northwest winds increasing behind the front. As the cooler air flows southward into the region today, the baroclinic zone will become enhanced as it stalls from Wyoming into Nebraska. The highest snow amounts are still expected in the convergence zone from the southern Black Hills into far southwestern South Dakota although the probability of >4 inches of snow in that area has greatly diminished.
Did go slighter cooler with this afternoons MaxT using the CONSRAW across all but northwest Oklahoma, where there is some sun between breaks in the clouds. Clear night skies combined with light to calm winds will enhance strong radiational cooling for one last night, as temperatures tonight drop to subfreezing (20s).
1152 AM CST Tue Mar 8 2022 High pressure will slowly slide southeast out of the region today with a weak trough pushing through northern Nebraska by late morning. This trough will bring the potential for some light snow to areas mainly along and north of a line from Alliance to Spencer.
A 500 mb trough is traversing eastward across northern Texas today with some weak perturbations moving over the region. Temperatures will remain below normal through the period with overnight lows tonight in the low 40s out west to low 50s in the Lower Valley. Zapata, Starr and Jim Hogg counties will warm into upper 60s and even a few spots reaching 70 degrees by the afternoon, but cooler temperatures, in the low to mid 60s, are expected where cloud cover will be be slower to break. With this said, if cloud cover dissipates earlier than anticipated we could see warmer temperatures across eastern portions of the CWA in the afternoon.
353 PM EST Tue Mar 8 2022 High pressure sprawled across the Ohio valley drifts into New England while low pressure moves into northern Ontario tonight. This places SE MI between systems until a dry cold front slides through the region Wednesday afternoon.
A mid level baroclinic zone will develop Wednesday night well ahead of the upper level trough.
Clouds should continue to erode as the trough axis shifts east of the region later this evening.
712 PM EST Tue Mar 8 2022 Brief high pressure across the region will be replaced by an advancing low pressure system to our south.
Pleasant conditions are in store for Wednesday as ridging at the surface and mid-levels gives way to clearing skies and temperatures in the 60s to near 70.
Dry and cool weather today will give way to slightly warmer temperatures on Wednesday.
430 PM MST Tue Mar 8 2022 Current surface map places cold front across central Wyoming into southern/central Nebraska. Upper trof combined with diurnal instability is bringing snow shower activity across much of the forecast area.
Expect the precipitation to taper off after midnight as an area of low pressure moves south of the state.
/issued 207 PM CST Tue Mar 8 2022/ The northern portion of an upper level trough axis is currently centered over the Texas Panhandle and will continue to lift northeast overnight. Zonal flow aloft by early Wednesday morning will quickly evolve into another broadening trough across New Mexico and West Texas by early afternoon.
Readings could end up a bit cooler if clouds hold into the evening.
Temperatures will continue to be cooler than normal tonight and Wednesday. /22/ A series of short waves followed by a potent mid-upper level trough will be the main story for this forecast period.
509 PM CST Tue Mar 8 2022 Summary: colder conditions are expected for Wednesday through the end of the week as a cold front moves through the Northland today.
Model soundings show quite impressive low level lapse rates over a deep layer and some decent moisture in the low levels.
626 AM EST Mon Feb 13 2017 High pressure will build over the area through Tuesday.
The current satellite water vapor image is showing a low pressure system sliding across the Mexico US boarder this morning. This low is advecting moisture into Colorado. Short term high resolution models are indicating that wrap around moisture associated with the previously mentioned low pressure system will continue to support rain and snow showers over southern portions of the western slope through at least Tuesday morning. Weather conditions are anticipated to improve Tuesday as the low pressure system continues to track east into the Great Plains and high pressure builds over the Great Basin and Intermountain West.
MORNING UPDATE: Changes to the forecast for this morning were mainly to hourly temperatures which are warmer than predicted by about 2 to 4 degrees. An amplified upper-level ridge centered over the Pacific Northwest Coast will extend north into British Columbia and the Yukon Territory this morning. By Tuesday the ridge axis slides over the Northern Rockies turning local flow aloft to northerly.
423 AM MST Mon Feb 13 2017 Primary meteorological concern is amount of impact that closed upper low has over the forecast district during the next 24 hours. Recent PV analysis, real-time data, computer simulations and forecast model soundings suggest that closed upper low located approximately 125 miles to the south of Tucson, Arizona at 12Z this morning will move to southeastern New Mexico by 12Z Tuesday. Weather pattern will revert back to dry and unseasonably warm this week as yet another warm ridge of high pressure crosses the Rockies.
616 AM CST Mon Feb 13 2017 A rather highly amplified pattern will persist for the next 36 hours, with fast NW flow aloft continuing to prevail over the western Great Lakes region underneath the western periphery of the large-scale upper trof that remains in place across the eastern U. A couple of fast-moving disturbances will traverse the region today and tonight as the amplify while moving toward the mean large-scale trof axis, each bringing chances for precipitation. In between these two waves, weak low level lift is forecast to persist tonight, especially across northeast MN, and with the loss of deep-layer ice for a 6-12 hour period between waves, freezing drizzle may become a bit of nuisance tonight/early Tuesday morning. A deepening trough over the Great Lakes will result in meridional flow across the western Great Lakes on Tuesday night.
Expect highs in the low to mid 50s. Tuesday will again be warm with continued westerly flow and highs in the low to mid 50s.
The cold front has pushed south over the Northern Gulf. Northerly winds have followed in the front's wake and drier, cooler air is gradually filtering in behind it. Overnight low temperatures inland are forecasted to generally bottom out in the low to mid 40s with upper 40s to mid 50s expected closer to the coast.
Broken midlevel clouds with winds dropping off to near calm are expected tonight after 00Z as high pressure will be over the area.
925 mb temps are warmest in the higher terrain over western Manitoba and then along the west side of the Red River valley and are in the 6-8C range midday-aftn in E ND. Favorable southwest to west to northwest wind will bring warmer air to the sfc, esp over the higher terrain west side of the RRV and likely into the RRV valley floor. Far eastern fcst area not quite as warm, but some sun with the green pine trees aiding the heat will help them warm up to above freezing as well. Situation today may well be on where temps are a lot warmer than any guidance suggests in those two areas. Thus may be too cool though did go with warmer guidance values. Precipitation chances south of the upper low into far NW MN seem quite low.
Upper ridge seen early this morning along the BC/Pacific NW coast on water vapor imagery, will push inland today and slide gradually SE across the region through Tue. The ridge will bring dry and warmer weather, with windy conditions from KBIL W Tue.
1055 AM EST Mon Feb 13 2017 Scattered snow showers should end today as high pressure builds in. Snow shower chances return with a Tuesday night cold front. Snow showers and flurries should gradually end early this afternoon as high pressure builds in. trough. A cold front will dive through, returning cold advection and northwest flow.
While temperatures will certainly be cooler overall today, still a bit tricky given the variable cloudiness this morning. Elsewhere, temps around 70F can be expected, except for the immediate Volusia Coast where onshore flow will keep conditions a bit cooler.
900 AM EST Mon Feb 13 2017 Pre-frontal trough just north of Lake Okeechobee this morning is helping to spread some cloudiness across South-Central Florida. All in all, another nice day is in store with high temperatures near to a couple of degrees warmer than yesterday based on low level thickness values.
The highest snow accumulations will be found over the mountains and along the adjacent high plains to the central mountains.
Wind speeds in the 5-7 kt range overnight coupled with a drier airmass ushered in by yesterday's cold front should mitigate fog potential overnight.
High pressure will keep dry conditions across the area through this upcoming weekend.
506 AM CST Mon Feb 13 2017 Surface map this morning features high pressure centered over MO with ridge axis extending northward into the Upper Mississippi River Valley. High pressure pushes off to the east today and a cold front drops through the Dakotas into MN. For Tuesday afternoon into Tuesday night, a cold front will drop across the area into the Great Lakes region for a chance of snow showers.
A closed upper low over northwest Mexico will track to near far West Texas by this evening and then across west and northwest Texas Tuesday. Out ahead of the closed upper low, forecast soundings indicate temps may stay close or slightly above freezing through Tuesday across the southern Texas Panhandle. Backed off on total snowfall accumulations across all of the forecast area with the highest amounts over the south central and southwest Texas Panhandle where 1 to 3 inches will be possible although confidence very low on this occurrence. As the upper low pulls east away from the Panhandles Tuesday, the precip should likely end from west to east by Tuesday afternoon.
426 AM CST Mon Feb 13 2017 Today and Tonight: In the wake of yesterday's cold front, cooler weather forecast for the ArkLaMiss region today. Highs will be within a few degrees of normal for this time of year, with clearing skies and lighter winds beneath a ridge of high pressure making for a pleasant mid-February day.
A cold front will sink slowly south across the forecast area today and will stall across south Florida tonight as it becomes parallel to the U/L flow.
1011 AM EST Mon Feb 13 2017 High pressure will build over the area through Tuesday.
927 AM EST Mon Feb 13 2017 Aviation section updated High pressure will keep dry conditions across the area through this upcoming weekend.
Mid level low pressure is beginning to lift out of the southwest US. Despite the moisture and lift spreading over the area the low levels remain fairly dry therefore precip is struggling to reach the ground. Given the depth of the low level dry air a decent amount of lift would be needed to saturate this layer. Skies will clear from north to south tonight, which could set up a gradient in the low temperatures.
A cold front has stalled near a Columbus to Cotulla to El Indio line. An upper level low is centered over Sonora state in Northwestern Mexico. Upper level low moves across the international border region today to out across the Southern Plains on Tuesday while opening up into a weakening trough. As the low/trough approaches, a surface wave forms on the front near the Rio Grande forcing the front back north to near the Escarpment and quite possibly into the Hill Country later today into evening. As the low/trough moves across New Mexico and out into the Plains, the front will surge to the east across South Central Texas tonight into Tuesday.
/Issued 311 AM CST Mon Feb 13 2017/ An upper level low currently over northwestern Mexico is slated to be the next weather maker for eastern Oklahoma and western Arkansas. Rain showers associated with this feature are expected to begin to move into eastern Oklahoma late this afternoon with the best chances of rain showers Tonight into Tuesday as the upper level low weakens and moves out of the southwest and across the Southern Plains. It continues to look like the higher rainfall totals will occur south of Interstate 40. The remainder of the work week will be dry as high pressure controls at the surface and aloft.
and expect patchy dense freezing fog to continue through about 1100 MST this morning in that area where a Dense Fog Advisory is in effect. A low pressure system moving east across northern Mexico will maintain shower activity over southeast Utah through today. High pressure aloft will strengthen across the region during the midweek period.
Precip type should predominantly be rain based on current reports, but there is still indication by RAP of sub 0C cold layer just deep enough for refreezing below warm layer (2-4C Tw Max). The short wave trough rotating out of the upper low over the far southwest U. Tonight and Tuesday the upper low over the southwest travels east across the southern plains as the upper ridge over the intermountain west moves over the Rockies and northern high plains region.
High pressure will be the overwhelming surface feature through tonight, despite the passage of a weak low level trough axis through the region this evening. Otherwise, low level winds shifting from southwest to west today plus the lack of an incoming colder airmass with the trough features and northwest flow aloft will mean another highly abnormally warm day today. Highs today will hit some 15-20 degrees above normal, coming awfully close to record highs, reaching the lower 40s to lower 50s.
An upper level low will move along southern portions of New Mexico today, then into western Texas tonight. Highs today will only reach into the 40s with lows tonight falling to around freezing.
Used a blend of model guidance highs today with a slight preference towards the cooler numbers. The mid/upper low is forecast to move along the Red River, west to east, during the day. Still appears precipitation should remain as rain, though some model guidance including the 00 UTC ECMWF suggested there may be outside chance for some wet snow mixing with the rain near and directly beneath the mid/upper low over western north Texas and far southwestern Oklahoma Tuesday afternoon and evening. Went towards the cooler side of guidance highs due to clouds and rain. Increasing north winds to bring in cooler and drier air should prevent any fog formation.
945 AM EST Mon Feb 13 2017 High pressure will ridge across the region from southwest to northeast through the day.
/Issued 348 AM EST Mon Feb 13 2017/ Clear and breezy conditions are impacting the state this morning in the wake of a cold front sagging into south Georgia. Light radar returns have diminished entirely, and a dry forecast is in place through the short term with high pressure returning to the region. Gusty winds have already begun settling this morning, but will remain at or near Wind Advisory criteria in the higher elevations of northeast Georgia through approximately 18z today. Temperatures will be slightly cooler today with the influence of the colder air mass. High temperatures will be a few degrees warmer on Tuesday.
The short wave trough rotating out of the upper low over the far southwest U. Tonight and Tuesday the upper low over the southwest travels east across the southern plains as the upper ridge over the intermountain west moves over the Rockies and northern high plains region.
Today Through Tuesday Night Drier and cooler airmass contd to advect into AR overnight following the passage of a CDFNT on Sun. An area of mid lvl clouds moved into SWRN AR early this mrng, keeping temps in the lower and mid 50s. Models have stayed in good agreement with the timing and track of the aforementioned storm sys, taking the low center to the S of AR late Tue and Tue ngt. Rainfall wl begin to taper off fm the NW late Tue ngt as the low center begins to shift E of the FA.
Light rain will develop over most terminals by noon becoming heavier by mid afternoon as an upper low approaches from the west. As an upper low west of El Paso approaches today, rainfall will become widespread from west to east. Much cooler otherwise today, with highs ranging from the mid 40s in the Big Country to upper 50s in the NW Hill Country, and lows tonight from the mid 30s in the Big Country to mid 40s from Junction to San Saba.
437 AM MST Mon Feb 13 2017 Ridge of high pressure will dominate the weather for the upcoming week with sunny skies and warming temperatures each day.
/issued 309 AM CST Mon Feb 13 2017/ High pressure over the Mid South today will move to the east by Tuesday as another storm system approaches from the west. An upper level low pressure system over northern Mexico today will move northeast over the next couple of days before becoming absorbed by a larger upper level trough digging across the eastern United States. As the upper low lifts northeast through Tuesday.
High pressure, that is currently building into north central Idaho and western Montana, is expected to reach its peak on Tuesday.
A broad ridge of high pressure was present across western Canada with a trough located from Hudson Bay south into the upper Ohio Valley. Disconnected from the northern stream, a closed low was located over Baja California. Guidance temperatures came in slightly warmer for this afternoon with the 00z forecast run earlier tonight and highs were trended upward from the upper 40s to lower 50s. Weak high pressure will build south into eastern Wyoming and Nebraska tonight. Clear skies and light winds will lead to lows in the lower 20s. This will drive a cold front south through the area. The airmass behind the front is mild Pacific air, and high temperatures will only be a couple of degrees cooler than today's highs.
As an upper low west of El Paso approaches today, rainfall will become widespread from west to east. Much cooler otherwise today, with highs ranging from the mid 40s in the Big Country to upper 50s in the NW Hill Country, and lows tonight from the mid 30s in the Big Country to mid 40s from Junction to San Saba.
604 AM EST Mon Feb 13 2017 High pressure moving into the forecast area from the west today will be over the area tonight and off the Southeast Coast Tuesday.
Will start out this morning with a persistent 500mb trough overhead, that will slide to our east Tuesday morning. trough Tuesday afternoon and evening.

/NF/ Today and Tonight: In the wake of yesterday's cold front, cooler weather forecast for the ArkLaMiss region today. Highs will be within a few degrees of normal for this time of year, with clearing skies and lighter winds beneath a ridge of high pressure making for a pleasant mid-February day.
Upper level ridge will continue to build today and remain in place through Tuesday.
744 AM EST Mon Feb 13 2017 Scattered snow showers should end today as high pressure builds in. Snow shower chances return with a Tuesday night cold front. The remaining scattered snow showers should taper off today under building high pressure. Winds have diminished in the ridges, but 12Z PIT sounding, and near term model data show a potential for some 40-50mph gusts in the ridges for a few hours this morning. The high wind warning was replaced with a wind advisory. trough. A cold front will dive through, returning cold advection and northwest flow.
352 AM PST Mon Feb 13 2017 Warmer today with weakening gusty north to northeast winds. A little cooler for Tuesday with a return of night and morning coastal low clouds and patchy fog.
Upper air analysis this morning showed a weak ridge extending from Texas to the northern plains. At the surface, high pressure extended down from the northeast and winds were generally light from the northeast. The upper level ridge will remain in place during this period.
While the profile was quite moist in the lowest levels, there was a considerable amount of dry air above 700 mb. We are on the west side of the cyclone and that implies subsidence. Highs Friday should reach into the low to mid 90s with low pops.
805 PM EDT Thu Sep 1 2016 Dry high pressure will maintain seasonably cool weather through the weekend.
