Aikyam-Lab/Synoptic-Bench huggingface dataset:
Despite plenty of sunshine, temperatures are currently in the upper 40s to lower 50s, around 20 degrees cooler than this time yesterday. Disturbances will round that trough and bring us a low chance of showers this afternoon along with an increase in cloud cover.
640 AM CDT Wed Apr 3 2024 (Today through Thursday) The line of storms has exited the area to the southeast, with a cold front stretching from near Anniston to Selma. A vertically stacked closed low system will spin over the Midwest today, with a secondary cold front arriving tonight over the Southeast.
Upper low continues to consolidate and deepen as it moves toward the Great Lakes. Trends will need to be closely watched and an upgrade to a High Wind Warning if confidence increases in the higher-end scenarios playing out. Winds begin to back off this evening but remain breezy through Thursday as the upper low is sluggish to kick east.
Otherwise, drier and much cooler weather will be in store for the forecast area as we go through the near term. A deep closed low is expected to shift east across the Great Lakes region, and strong subsidence and a fairly tight pressure gradient on the outer periphery of the low will support wind gusts just under wind advisory criteria later this morning and afternoon.
A cold front is currently in the process of moving through the area, bringing cooler temperatures and light snow above 2000-2500 feet Wednesday. As of 2AM Wednesday, a weak cold front is in the process of moving through the area, though QPF values look low for the initial passing of the front. 25" of QPF is expected in the lowlands through Wed midday, and less than 0.
641 AM CDT Wed Apr 3 2024 (Today through Thursday) A weakening upper level trough axis continues to move south of the region today as northwest flow aloft develops behind the trough axis. At the surface, high pressure to our west gradually weakens as a trough develops by late afternoon across eastern New Mexico.
A noticeable drop in high temperatures from yesterday as afternoon highs today only reach the low to mid 70s. Thursday morning temps, went with the NBM25 as most models and MOS data were running much cooler than the deterministic. High pressure builds in at the surface later today and parks itself for a few days, keeping conditions rather quiet and skies sunny.
Cool and windy conditions will prevail for the next few days as an upper level low pressure system churns over the OH River Valley.
349 PM EDT Wed Apr 3 2024 A cold front will bring rain chances to an end from west to east this afternoon and evening. Cooler and drier conditions arrive for Thursday through the weekend as dry high pressure builds in. A cold front is on our doorstep as dewpoints in the 40s and mainly clear skies lie not far to our northwest. Temperatures will be limited by cold advection tonight and subsidence tomorrow as the mid-level trough axis passes overhead, leading to overnight lows in the mid-40s to around 50F and daytime highs in the low-mid 60s.
Forecast soundings suggest the northwest to north BL winds will undercut the instability, although some anafrontal stratiform rains may linger into the afternoon behind the cold front.
High temperatures Thursday afternoon will be around twenty degrees cooler than this afternoon.
High pressure shifts east and winds will go light tonight and then switch around to the south.
337 PM EDT Wed Apr 3 2024 Strong low pressure near Chicago will move southeast into Ohio tonight and into the Northeast on Thursday as strong high pressure builds south from Canada into the Upper Mississippi River Valley.
With light winds & clear skies, seasonably cool conditions in the low 40s are expected.
- Warmer temperatures at the end of the week and into the weekend will melt much of the snow and lead to rises in area rivers. Another upper level disturbance will drop southwestward around the upper low late tonight, bringing another concentrated area of snow mixed with rain at times. Temperatures will be at or above freezing across the Fox Valley and lakeshore, thus think most of the accumulation will be on grassy surfaces. As you head north and west of the Fox Valley, temperatures will be around the freezing mark or slightly below across the north. On Thursday, the upper low continues to move away which should bring a diminishing trend in the precipitation. It will be warmer with highs in the middle 30s to lower 40s.
1152 AM CDT Wed Apr 3 2024 (Today through Thursday afternoon) An upper level ridge moves in overhead for today and the rising heights will lead to temperatures reaching into the 70s for most. Normal highs for the beginning of April sit in the mid to upper 70s (for KMAF it's 78F for the high and 48F for the low) and that is where most locations will end up. The warming trend continues on Thursday with highs reaching into the low 80s for most.
Low temperatures tonight will be about 10 degrees warmer than this morning, but still fairly chilly into the 40s. Ridging builds over the area Thursday with increasing heights and warming mid level temperatures.
Issued 236 PM CDT Wed Apr 3 2024 Tonight through Thursday night: Low pressure centered just off the shore of Kenosha County will continue to slide south and east into tonight. Snow will then taper off towards noon as the upper low pulls east and PVA decreases.
Up to an inch and a half of snow is possible tonight in the highland areas of northern lower Michigan and this would be later tonight as the moisture moves in and temperatures cool to near freezing. Additional snow accumulations should be minimal with the higher terrain possibly picking up another half inch or less Thursday morning.
1217 PM CDT Wed Apr 3 2024 (Rest of today through Thursday) Much cooler and breezy conditions have developed across Middle Tennessee after last evening's cold frontal passage. The main system impacting our wx today through Thursday will be a large and deep low pressure system that will move from the Great Lakes to the northeast states. The upper level trough will be located further to the east on Thursday and that will bring a drier forecast, but a few showers will pop up again for the northeast half of our area. (Thursday Night through next Wednesday) The upper level trough will continue to move east Thursday night allowing more clearing with lighter winds.
146 PM EDT Wed Apr 3 2024 An upper level low pressure system will move slowly east across the Ohio Valley through the end of the work week, resulting in occasional showers and much cooler temperatures. Weak high pressure will lead to drier conditions and a bit of a warmup for the weekend. Very deep and anomalous H5 trough with height anomalies to -3. The upper level low will rotate east across the upper Ohio Valley tonight into Thursday. As some cooler air moves in from the northwest, some snow showers will mix in with the rain showers tonight into Thursday morning. Temperatures will remain seasonably cold with lows tonight in the low to mid 30s and highs on Thursday mostly in the mid 40s.
The exception will be along the Lower Texas beaches, where low temperatures will likely only fall into the low 60s. Temperatures will range from the mid 70s along the Lower Texas beaches to upper 80s across the Northern Ranchlands. Low temperatures Thursday night will be a few degrees warmer with the return of low level southerly flow, but will still be several degrees below normal for early April, ranging from the upper 50s across the Northern Ranchlands to low 60s across the Lower RGV and Texas beaches.
/Issued 1258 PM CDT Wed Apr 3 2024/ /Through Tomorrow Afternoon/ As weak ridging inches closer to North and Central Texas, quiet weather conditions will persist through tomorrow afternoon. The return of southwesterly winds will yield warmer conditions tomorrow.
1218 PM CDT Wed Apr 3 2024 (Today through Thursday) A weakening upper level trough axis continues to move south of the region today as northwest flow aloft develops behind the trough axis. At the surface, high pressure to our west gradually weakens as a trough develops by late afternoon across eastern New Mexico.
Radiative cooling tonight will result in another cool morning Thursday morning before temperatures warm up quickly during the day with the help of surface flow becoming southwesterly and upper level ridging beginning to build in from the west.
A deep upper-level low continues to propagate across the Great Lakes region as an associated trough axis and cold front move across the Florida peninsula. As this trough swings through and the attendant cold front pushes south, a cooler and drier airmass will then filter in as upper-level ridging builds back across the region.
/NEW/ /Through Tomorrow Afternoon/ As weak ridging inches closer to North and Central Texas, quiet weather conditions will persist through tomorrow afternoon. The return of southwesterly winds will yield warmer conditions tomorrow.
(Now through Thursday) Drier conditions have moved into the area in the wake of last nights system and cold front. The large upper trough that brought storms has slowly drifted eastward brining a more westerly to northwesterly wind a loft. Expect a temperature forecast with highs struggling to reach the low 70s tomorrow and lows in the 30s and 40s the next two night.
(This afternoon through Thursday) Most of Central Alabama is now observing mostly sunny skies in the wake of the strong cold frontal passage. Gradient winds will continue to gust from the northwest between 25 and 30mph at times with the very potent, stacked low pressure system remaining over Lake Michigan. A much cooler Continental Polar airmass is settling in over the Southeast as we approach the afternoon hours, with highs expected to be around 10 degrees below normal for this time of the year. Chilly temperatures in the low to mid 40s can be expected overnight tonight followed by another breezy and chilly day on Thursday as the vertically stacked low pressure system moves southeastward toward Ohio.
(Rest of today through Thursday) Much cooler and breezy conditions have developed across Middle Tennessee after last evening's cold frontal passage. The main system impacting our wx today through Thursday will be a large and deep low pressure system that will move from the Great Lakes to the northeast states. The upper level trough will be located further to the east on Thursday and that will bring a drier forecast, but a few showers will pop up again for the northeast half of our area. (Thursday Night through next Wednesday) The upper level trough will continue to move east Thursday night allowing more clearing with lighter winds.
(Rest of today through Thursday) Surface analysis and satellite imagery early this afternoon places a cold front over northern Florida, with a line of strong showers and thunderstorms extending from northeast to southwest across the peninsula. Shower activity could linger through the early morning hours before the front clears the area, ushering in drier, cooler continental air. Conditions will cool down once the front clears the area tonight, with minimum temperatures dropping to the low to mid 60s for much of the region.
Strong high pressure is sinking down south-central Canada, through the MS River Valley & into the Gulf Coast states. Otherwise, drier and much cooler weather will be in store for the forecast area as we go through the near term. A deep closed low is expected to shift east across the Great Lakes region, and strong subsidence and a fairly tight pressure gradient on the outer periphery of the low will support wind gusts just under wind advisory criteria later this morning and afternoon.
(This evening through Thursday) Current water vapor imagery depicts an upper level low spiraling eastward across the Great Lakes region and an upper level ridge over the western US. The upper level ridge is expected to shift west overnight into the South Plains region; therefore, allowing relatively warm and quiet weather to prevail over the FA. These light winds and clear skies will allow for another night of cooler temperatures in the 40s across the FA. These southwest winds in combination with increased thickness values and clear skies will help boost temperatures into the lower to mid 80s.
- Dry and warmer for at least the start of the weekend.
Across the lowlands, expect another dreary day Thursday with low stratus clouds and rounds of light showers, with potentially some light snow showers mixed in. A much cooler day is expected with highs only in the upper 40s.
There is still a 20-30% chance gusts could reach 45 mph, the highest chances west of I-55.
Areas in north central Oklahoma are showing a 30-40% chance of dropping to freezing.
BB/03 (Now through Thursday) The cold front continues to move east early this morning and is resulting in a wide range of temperatures across the area. A cooler and much drier airmass will continue to spread east in the wake of the front today. Winds ease overnight and low temperatures will be noticeably cooler with lower and middle 40s expected inland and lower 50s along the immediate coastal interface.
A few areas along the KS and Missouri borders may still approach freezing, but the vast majority will not quite reach it. (Tonight through Wednesday) Winds will shift to light northeasterly as cool air continues to move into the area Thursday around the periphery of the departing upper level low.
Showers continue today as a slow moving cold front approaches the Northern Rockies.
These northwesterly winds are making temperatures max out around 60 degrees today, about 20 degrees cooler than yesterday.
/19/ (Wednesday through Thursday) Northwest winds will continue to bring a very noticeably cooler and less humid airmass into the region today. This can already be felt, as current temperatures this morning have already dropped into the 40s areawide, which is about 25 degrees cooler than temperatures were at this time last night. Winds have taper down across the area this morning, but another longwave trough will push through the Southern Plains and Lower Mississippi Valley today, bringing more gusty conditions.
234 PM CDT Wed Apr 3 2024 - Trending warmer and dry for the rest of the work week.
628 PM CDT Wed Apr 3 2024 (Rest of today through Thursday) Much cooler and breezy conditions have developed across Middle Tennessee after last evening's cold frontal passage. The main system impacting our wx today through Thursday will be a large and deep low pressure system that will move from the Great Lakes to the northeast states. The upper level trough will be located further to the east on Thursday and that will bring a drier forecast, but a few showers will pop up again for the northeast half of our area. (Thursday Night through next Wednesday) The upper level trough will continue to move east Thursday night allowing more clearing with lighter winds.
629 PM CDT Wed Apr 3 2024 - Trending warmer and dry for the rest of the work week.
Mid evening satellite imagery/RAP analysis showed the circulation around a stacked low pressure system spinning over the Great Lakes region. Our CWA was just far enough south of the low that the associated stratocu will be just northeast of our northern zones. With light winds & clear skies, seasonably cool conditions in the low 40s are expected.
This is an indicator of the high pressure ridge overhead that is delivering clear skies, light winds, and warm temperatures.
736 PM EDT Wed Apr 3 2024 Strong low pressure near Chicago will move southeast into Ohio tonight and into the Northeast on Thursday as strong high pressure builds south from Canada into the Upper Mississippi River Valley.
Another beautiful spring day is in store for Thursday, but will be a little warmer than today. The lows Thursday night will warm up a few degrees as well, generally ranging in the low to upper 50s inland and in the low to mid 60s along the coasts.
Temperatures are currently trending approximately 5 to 20 degrees cooler than this time yesterday afternoon, valid at 230 PM PDT.
550 PM CDT Wed Apr 3 2024 Cool and windy conditions will prevail for the next few days as an upper level low pressure system churns over the OH River Valley.

839 PM EDT Wed Apr 3 2024 A cold front will bring rain chances to an end from west to east this afternoon and evening. Cooler and drier conditions arrive for Thursday through the weekend as dry high pressure builds in. A cold front is on our doorstep as dewpoints in the 40s and mainly clear skies lie not far to our northwest. Temperatures will be limited by cold advection tonight and subsidence tomorrow as the mid-level trough axis passes overhead, leading to overnight lows in the mid-40s to around 50F and daytime highs in the low-mid 60s.
857 PM CDT Wed Apr 3 2024 Clouds associated with an upper level low over the Ohio Valley continue to rotate across eastern Missouri into West Tennessee. Clouds should also lift out of the area as the upper level low tracks off to the east.
1001 PM EDT Wed Apr 3 2024 A strong cold front will push across the area tonight. Transition to a cooler/much drier pattern. Have therefore sided with higher guidance for temps, and lower guidance for TD's in the low 30s. A few iso showers will be possible, especially across the northern half of the forecast area, courtesy of the upper low pushing through the Mid-Atlantic. Another ridge of high pressure building in from the west with cooler, drier and breezy weather forecast to end the week through the weekend.
With the clear skies, expect overnight lows in the lower to mid 40s north of I-10, upper 40s to lower 50s further south.
646 PM CDT Wed Apr 3 2024 (This evening through Thursday) Current water vapor imagery depicts an upper level low spiraling eastward across the Great Lakes region and an upper level ridge over the western US. The upper level ridge is expected to shift west overnight into the South Plains region; therefore, allowing relatively warm and quiet weather to prevail over the FA. These light winds and clear skies will allow for another night of cooler temperatures in the 40s across the FA. These southwest winds in combination with increased thickness values and clear skies will help boost temperatures into the lower to mid 80s.
745 PM EDT Wed Apr 3 2024 A cold front will move offshore this evening and tonight.
Weather pattern has changed a lot behind surface cold frontal passage with upper level low positioned to our north main weather player through tonight. (Rest of today through Thursday) Much cooler and breezy conditions have developed across Middle Tennessee after last evening's cold frontal passage. The main system impacting our wx today through Thursday will be a large and deep low pressure system that will move from the Great Lakes to the northeast states. The upper level trough will be located further to the east on Thursday and that will bring a drier forecast, but a few showers will pop up again for the northeast half of our area. (Thursday Night through next Wednesday) The upper level trough will continue to move east Thursday night allowing more clearing with lighter winds.
The lighter winds overnight, along with clear skies, will allow temps to radiate down to just above freezing by Thursday morning across far NE OK into NW AR, with upper 30s elsewhere. A few areas along the KS and Missouri borders may still approach freezing, but the vast majority will not quite reach it. (Tonight through Wednesday) Winds will shift to light northeasterly as cool air continues to move into the area Thursday around the periphery of the departing upper level low.
655 PM EDT Wed Apr 3 2024 A strong cold front will push across the area tonight. Transition to a cooler/much drier pattern. Have therefore sided with higher guidance for temps, and lower guidance for TD's in the low 30s. Another ridge of high pressure building in from the west with cooler, drier and breezy weather forecast to end the week through the weekend.
(Rest of tonight) Lingering cloud cover continues to spread into the area from the NW this late Wed evening, as a low pressure system at the sfc and aloft tracks eastward across the OH Valley. Current temps are mainly in the lower 50s/near 50F, but with the continued influx of cooler air, lows into early Thu look to fall more into the upper 30s/near 40F for most spots. Given some lingering moisture below H7 remaining in place coupled with weak dynamic lift from the upper trough axis to the north, a few sprinkles cannot be ruled out as well heading into Thu morning.
