Aikyam-Lab/Synoptic-Bench huggingface dataset:
Surface analysis this morning places a ridge of high pressure over the Mid-Atlantic and Southeast United States while a cold front is located from the Great Lakes Region back through East Central Missouri, Northwest Arkansas and into the Red River Valley in Texas/Oklahoma. As of 4 AM CDT, temperatures across the Mid-South range from around 40 to the lower 40s near the Tennessee River and upper 40s to lower 50s mainly along and west of the Mississippi River.
526 AM EDT Thu Oct 24 2019 High pressure will push off the Mid Atlantic coast today, as a dying cold front pushes into northwest Pennsylvania. The weak cold front will stall over northwest Pennsylvania Friday, then push south of the state Friday night.
Weakly cyclonic flow lingers this morning with low level thermal trough in place. High pressure nudges into the area tonight and dominates into Friday. Medium Surface cold front has shifted off to the east with northwest winds bringing a weak cold advection regime. The low level thermal trough swings through today. Cooler 925 temps should knock temps for most back into the 40s. Medium to High Surface ridging builds into the area with quiet conditions. The high shifts slightly east on Friday so we start to see the beginnings of a return flow take shape.
Breezes are expected to rapidly ease later Friday night as they veer southeasterly in the wake of a westward moving trough.
A cold front will slowly move through the area today, reaching KABI and KSJT between 15Z and 16Z and the southern sites this afternoon. As the cold front and its associated system move across the region, during the next 24 hours, showers and thunderstorms may develop, across West Central Texas.
High pressure aloft will expand east across the western states through Friday.
An upper level ridge of high pressure will bring dry and warm weather to the region today.
642 AM EDT Thu Oct 24 2019 A weakening cold front will offer an increase in clouds, as it pushes southeast into the Ohio Valley today. This front will wash out on Friday, as high pressure builds into the Great Lakes.
Expect VFR conditions through the TAF period with just light southerly winds becoming easterly late this evening in advance of an approaching low pressure system.
524 AM MDT Thu Oct 24 2019 A broad trough covers the CONUS, as a ridge builds over the west coast. Satellite shows some mid/low clouds drifting into the CWA, as high pressure slides into the region. As the upper ridge shifts eastward, warmer air will advect into the region today and Friday.
429 AM MDT Thu Oct 24 2019 GOES-16 satellite imagery shows the base of the upper trough over the southern border between CO and NM continuing to move ESE. The cold frontal surge and upper level trough helped to bring snow to the mountains, foothills and portions of the eastern plains. Areas that are better favored in northeast surface flow had the highest amounts with less as you went north to Wyoming and ESE onto the plains. Prolonged northerly flow will hinder warm air advection and keep temperatures cooler in the 40s for the lower elevations and 20s to 30s for the mountains and foothills.
742 AM EDT Thu Oct 24 2019 High pressure will push off the Mid Atlantic coast today, as a dying cold front pushes into northwest Pennsylvania. The weak cold front will stall over northwest Pennsylvania Friday, then push south of the state Friday night.
Expect much cooler temperatures on Thursday with gusty northeast winds.
1039 AM EDT Thu Oct 24 2019 High pressure will push off the Mid Atlantic coast today, as a dying cold front pushes into northwest Pennsylvania. The weak cold front will stall over northwest Pennsylvania Friday, then push south of the state Friday night.
14Z or 9AM surface analysis has cold front through much of west Texas and entering the Big Country. Upper level trough lags behind the front and should push across Texas tomorrow. NHC did issue a special tropical weather outlook to increase the probability of tropical cyclone formation in the Gulf to 50 percent. This disturbance is expected to remain in the Gulf and overtaken by the cold front tomorrow. Saturation increases late this afternoon as a cold front approaches from the west.
/issued 408 AM EDT Thu Oct 24 2019/ A quiet start to the short term as high pressure has developed eastward and now resides over the Mid Atlantic states with ridging through North GA. Deese A wet and unsettled weekend is on tap for the area given strong moisture advection and some upglide east of closed upper trough energy progged to push from the Arklatex to the Ohio Valley.
The nice weather unfortunately comes to an end tomorrow as a deep upper trough currently digging into the southern Plains cuts off into an upper low over Texas and Oklahoma. As this occurs, a surge of deep moisture from the Gulf of Mexico will race northward late tonight and tomorrow atop the cooler and drier airmass in place over us.
Upper trough, currently over the four corners region, will slowly shift southeast into the southern Plains today into tonight. A cold front has been slowly sagging south overnight and is currently stretched across southeast Oklahoma into west-central Arkansas.
Local sfc analysis this morning shows an evolution to more of a coastal trough setup has occurred since last night with a wedge of lower dewpoint air residing inland roughly along and west of I-4. Low will remain quite mild in the low to mid 70s, with upper 70s possible along coastal area south of the Cape. A warm front will be stretching from west to east just south of the FL Panhandle on Friday, keeping east central FL warm (highs will reach the upper 80s across the interior and mid 80s along the coast). Maxs on Sat will be similar across the interior but a few degrees warmer along the coast than Fri. As a warm front lifts north and away from the FL peninsula on Fri and Sat, winds will shift from east to southeast.
Another cool day today before a brief warm-up, as elongated trough slides across the region. Highs today will be a little warmer than yesterday, but still only in the 40s.
445 AM MDT Thu Oct 24 2019 Patchy valley fog and freezing fog will be present across the Northern Rockies through this morning.
Issued by National Weather Service Huntsville AL 740 AM EDT Thu Oct 24 2019 High pressure will remain in place across the eastern TN Valley thru the valid TAF period, with VFR conditions and lgt/vrbl flow anticipated at both TRI/CHA.
/issued 321 AM EDT Thu Oct 24 2019/ A weak mid level ridge is holding over the Florida Peninsula today as a broad trough digs into the southern Plains.
621 AM EDT Thu Oct 24 2019 Dry high pressure will prevail today. As this occurs, the low level flow will begin to veer more onshore as moisture slowly spreads north and west into the area. High clouds are present along the coastal plain within the western periphery of an upper level ridge centered just off the southeast U. Temperatures should be near or slightly warmer than observed highs yesterday, but the late day cloud cover should prevent significant warming. The forecast will indicate highs in the lower to mid 70s as a result. Ridge centered over the Mid Atlantic and northeast extending into the Carolinas but weakening. Warmer temperatures at night than previous nights due to increasing moisture.
727 AM EDT Thu Oct 24 2019 Weak cold frontal boundary is currently pushing southward through Southeast Michigan easily noted in surface observations. The advertised mean longwave trough axis has become established from the 4-Corners into northeast Canada and will demonstrate only slight forward progress over the next 36 hours as energy consolidates and increasingly cuts off invof the panhandles of Texas and Oklahoma. The bulk of the forecast for the weekend is clear cut in that mostly- cut-off energy near the Arklatex region will be forced to lift through the Ohio Valley and the Lower Great Lakes in response to the next round of height falls over the West Coast.
Friday will be the warmest day through the extended as pre- frontal warming will occur ahead of a strong cold front that will sweep across the forecast area Friday night.
307 AM PDT Thu Oct 24 2019 High pressure will be in control of our weather for the first half of the weekend.
Expect dry conditions today and Friday with high pressure building in from the southwest. Expect cooler temperatures this morning behind an exiting cold front.
A low pressure system will continue to bring northerly winds to the region today.
541 AM CDT Thu Oct 24 2019 Northwest winds behind a cold front, will bring cooler conditions to the area today. High pressure will bring dry and cool weather for Friday. Cold front was located just west of the I-57 corridor at 2 AM. Some light overrunning rain is expected to develop this morning over MO, as low pressure develops well to our south. Cold advection behind the boundary will bring much cooler air today, with highs only reaching the low/mid 50s for most areas. High pressure builds across northern Illinois on Friday, allowing for dry but cool weather.
Westerly flow will lead to good mixing today, despite cooler temperatures aloft.
As the cold front and its associated system move across the region, during the next 24 hours, showers and thunderstorms may develop, across West Central Texas.
513 AM EDT Thu Oct 24 2019 High pressure just south of the Keystone state this evening will move off the east coast on Thursday. A weak cold front will sag south across the area late Thursday and Friday.
Ahead of developing low pressure system in the Canadian prairies an axis of warmer 925mb temps lifts into the area. A rise of about 10C at 925MB from this afternoon will allow temps to reach into the low to mid 50s, possibly for the last time this year, with some breeze on 10 to 20 mph SW winds. Thermal axis and strong mixing will keep temps up ahead of the cold front Friday night lows around 40.
Latest water vapor imagery shows an upper ridge extending from the Pacific offshore waters by CA across the West Coast with an upper trough extending from the Upper Midwest to the Southern Rockies. This upper ridge will flatten and breakdown the next 24 hours as it shifts eastward over the Northern Plains early Friday as the next upper trough moves into the Pacific Northwest and Northern Intermountain West by late Friday. This will promote highs tomorrow to be 10-20 degrees warmer than today. A cold front will sweep across the region which will bring concerns to gusty winds and cold temperatures.
Morning surface analysis shows cold front has now pushed south of Tulsa and northwest Arkansas and extends through southeast Oklahoma. Snow is falling across the TX panhandle, northwest of Amarillo, evident of the cold air moving into the High Plains.
Quiet conditions continue today under the influence of high pressure. Dry conditions expected through Friday ahead of an approaching cold front.
332 PM CDT Thu Oct 24 2019 As of 20Z Thursday afternoon, an upper low continues to progress eastward across Southern Plains with its current position near the NM/TX border.
Blowing snow, with some accumulations, continue to occur in this band as temperatures across the western half of the Texas Panhandle has fallen below freezing. Otherwise, expectation continues to be that the upper low over New Mexico will continue to move south and eventually southeast as the day progresses. Once this low passes, drier arctic air should filter in behind this storm system and start to bring snow chances down from west to east.
258 PM EDT Thu Oct 24 2019 High pressure will push off the Mid Atlantic coast today, as a dying cold front pushes into northwest Pennsylvania. The weak cold front will stall over northwest Pennsylvania Friday, then push south of the state Friday night.
Positive tilt mid-level trof will continue to advect toward the southeast overnight, as mid-level s/w ridge builds across the forecast area out ahead of the next trof digging into the northwest CONUS. Friday night lows should be relatively mild as warmer airmass slides into the western CWA just ahead of progressive frontal boundary.
315 PM CDT Thu Oct 24 2019 An upper level positively tilted trough was continuing to dig across the Front Range of the Rockies into the Southern Plains at mid afternoon. A surface cold front was located from the Ohio River across the Missouri Bootheel into a low over north central Texas. The upper low will become cut off over the Southern Plains on Friday.
305 PM CDT Thu Oct 24 2019 Cool northerly surface flow continues in the wake of the cold front which moved through the area Thursday. Cloud cover will slowly erode late tonight, helping overnight lows to trend cooler, reaching the freezing mark across northern Missouri and down to the mid 30s further south.
Sct coverage will continue through daybreak as the winds in the lower layers increase into Friday. Highs Sat will be similar across the interior but a few degrees warmer along the coast than Fri. A low pressure with an attached cold front will be lifting to the northeast from the eastern states of the Midwest on Sun. This low will then reach the southeast US by Tue morning. After this, GFS and Euro don't agree on what this low will do. GFS shows the low lifting more towards the northeast and by Wed its associated front will push towards FL. However, the Euro develops a broad area of low pressure and instead builds a ridge across the local area from the northeast. Deep onshore flow with low-level ridge axis situated north of ECFL.
These two ingredients combined with the lift of the warm advection on the east side of the upper low will combine in the form of moderate to occasionally heavy precipitation at times through at least tomorrow early afternoon.
Friday will be the warmest day of the entire forecast period with highs in the lower 50s east to the lower to mid 60s west under a mostly sunny sky.
100 PM CDT Thu Oct 24 2019 /18Z TAFS/ Cold front extending from just north of Sonora and Brady at 1745Z was moving slowly south. A cold front will slowly move through the area today, reaching KABI and KSJT between 15Z and 16Z and the southern sites this afternoon. /issued 519 AM CDT Thu Oct 24 2019/ (Today and Tonight) As the cold front and its associated system move across the region, during the next 24 hours, showers and thunderstorms may develop, across West Central Texas.
Lows could possibly be in the low to mid 30s by Wed and Thu mornings.

901 AM MDT Thu Oct 24 2019 High pressure aloft will expand east across the western states through Friday.
Band of showers of thunderstorms along and behind the cold front from Ozona and Sonora to Eden. However isolated areas of light rain will continue to be possible overnight, especially over over the Big Country, closer to the upper low as it moves east from the Panhandle into Oklahoma. Kept high temperatures slightly cooler than guidance in the upper 40s in eastern zones from Brownwood to Abilene to Throckmorton, where skies will clear late afternoon.
A nice rebound by about 10 degrees should occur tomorrow as temps reach the low to mid 50s by late afternoon.
An upper level trough with axis extending from the eastern part of the Dakotas down to northeastern New Mexico will progress east through the rest of the day with northerly flow over the Tri-State area. Thursday night, the trough will continue to move out of the area with a ridge over the western CONUS nosing into the Tri-State area. Friday, the ridge will remain the western CONUS with an upper ridge pushing into the northwestern states through the day. Friday night, the upper trough over the northern states will push south into portions of northwestern Montana through northeastern Washington.
313 PM CDT Thu Oct 24 2019 A cold front has pushed through portions of Northeast Arkansas and the Missouri Bootheel this afternoon as winds have turned around to the north or northeast at Corning, Arkansas and Kennett, Missouri.
The forecast issue will be if the precipitation invading ht southern tier of KS counties might be intense enough to overcome warmer low to mid 40s surface temps and change over to snow. Temperatures will be even colder than the night before, from just sub freezing near Medicine Lodge to the mid 20s from Hays to Liberal and possible some upper teens in the far west as clear sky and light westerly winds develop. A very fall-like day expected on Friday with full sunshine through the day, light winds and temperatures varying from the mid 50 in the lower Plains central KS counties to closer to around 60 in west central Kansas where the drier air can heat more efficiently. Friday night looks only marginally warmer than tonight.
Northerly flow continues across East Idaho with upper ridge to the west. Flow becomes more zonal through the day with 700mb jet dropping south through the region ahead of cold front.
Issued by National Weather Service North Platte NE 1219 PM MDT Thu Oct 24 2019 A broad trough covers the CONUS, as a ridge builds over the west coast. Satellite shows some mid/low clouds drifting into the CWA, as high pressure slides into the region. As the upper ridge shifts eastward, warmer air will advect into the region today and Friday.
Moist flow from out of the south will continue to bring in warmer temps and higher dew points. Overnight low temperatures will be in the mid to upper 60s for most inland areas and can reach into the lower 70s for coastal areas and for counties south of the I-10 corridor.
Tonight will likely be the first time that La Crosse Regional Airport has fallen below freezing since April 15.
152 PM CDT Thu Oct 24 2019 An upper trough sits over most of the CONUS as ridging builds over the west cloast. This ridge pushing eastward will set up some WAA over the area, warming us up to near normal over the next 48 hours.
The warm front will start slowly lifting north, bringing the cloud cover currently along the Gulf of Mexico north into the Tennessee Valley. The low pressure system currently centered right near DFW will be our weather maker for the next couple days. As this low pressure system starts to pick up the boundary currently over the Gulf of Mexico, the inverted trough north of the front will bring rain into northern Alabama and southern Tennessee starting Friday morning. With the warm front finally lifting north of the area late Friday night, rain should start to decrease, and become more showery in nature.
Expect much cooler temperatures today with gusty northeast winds and very low relative humidity values.
Elsewhere winds will decouple to around 5 mph or so allowing temperatures to fall to around 20F or the lower 20s.
1240 PM CDT Thu Oct 24 2019 Clouds keeping temps down across the Devils Lake basin with temps holding into the low 30s will lower highs there accordingly. To the east sun and light SW winds will help warm temps into the low to mid 40s. Upper level ridge over western Canada will shift east and flatten across southern Canada. Upper level jet on the northern periphery of ridge will nose into Ontario by 00Z Sat. Upper level trough will follow in tow and move over southwest Canada by Fri afternoon. For today, an upper trough will move across the area with warm advection.
It looks like the snow-free areas will get several degrees warmer than forecast today. GOES-16 satellite imagery shows the base of the upper trough over the southern border between CO and NM continuing to move ESE. The cold frontal surge and upper level trough helped to bring snow to the mountains, foothills and portions of the eastern plains. Areas that are better favored in northeast surface flow had the highest amounts with less as you went north to Wyoming and ESE onto the plains. Prolonged northerly flow will hinder warm air advection and keep temperatures cooler in the 40s for the lower elevations and 20s to 30s for the mountains and foothills.
The strongest winds are expected to occur in the high terrain and along the Divide. A cold front is set to move through north-central Idaho and western Montana during Friday evening, which will enhance wind gusts.
528 PM MDT Thu Oct 24 2019 Some cumulus clouds have developed over the higher terrain in northerly flow in the wake of yesterday's storm system. A few showers appeared on radar over the central high terrain mainly affecting the higher peaks with some light snow falling when looking at webcams. Still will remain under a dry northerly flow with high pressure building in to the west with temperatures getting closer to normal by Friday afternoon.
An upper trough sits over most of the CONUS as ridging builds over the west coast. This ridge pushing eastward will set up some WAA over the area, warming us up to near normal over the next 48 hours.
/issued 313 PM CDT Thu Oct 24 2019/ A cold front has pushed through portions of Northeast Arkansas and the Missouri Bootheel this afternoon as winds have turned around to the north or northeast at Corning, Arkansas and Kennett, Missouri.
Healthy lower through mid level ridging is stacked above this. Short Term Update - High pressure to our north will remain nearly stationary and begin to be reinforced overnight. Broad high pressure centered over the Mid Atlantic coast area is responsible for moderate to fresh east breezes across the Keys and surrounding waters.
703 PM CDT Thu Oct 24 2019 An upper level positively tilted trough was continuing to dig across the Front Range of the Rockies into the Southern Plains at mid afternoon. A surface cold front was located from the Ohio River across the Missouri Bootheel into a low over north central Texas. The upper low will become cut off over the Southern Plains on Friday.
High pressure over the will result in warm temperatures, light winds and dry conditions across the state for Friday.
Cold air remains in place in the Midwest today, as a broad upper trof remains positioned from the Great Lakes to near the 4-corners area of the South.
Lows could possibly be in the low to mid 30s by Wed and Thu mornings. high clouds overnight as high pressure continues to slide away.
High pressure to the north continues easterly flow across the area.
205 PM PDT Thu Oct 24 2019 High pressure will be in control of northeast California and western Nevada through the first half of the weekend.

1032 PM EDT Thu Oct 24 2019 A dying cold front will stall over northwest Pennsylvania Friday, then push south of the state Friday night.
349 PM MDT Thu Oct 24 2019 We'll have quiet weather through Friday as drier and warmer air aloft moves over in moderate northwest flow aloft. Strong winds will be limited to the higher mountains, though it still looks like there will be a period late tonight and early Friday of mountain wave winds that will likely drop into the US 285 corridor in South Park.
A high pressure ridge will shift east tonight followed by a dry northwest flow aloft on Friday.
Quiet night so far across the area as the strong upper low that will bring us heavy rain is out in the southern Plains.
909 PM EDT Thu Oct 24 2019 915 MHZ profilers show deepening and increasing onshore flow as the pressure gradient tightens with high pressure strengthening well to our north.
644 PM CDT Thu Oct 24 2019 Cool northerly surface flow continues in the wake of the cold front which moved through the area Thursday.
