Aikyam-Lab/Synoptic-Bench huggingface dataset:
This afternoon will be dry with a few breaks of sunshine as high pressure builds in from the Ohio valley. Tonight should be mostly clear as high pressure builds into the region with lows generally in the 20's. One wrinkle tonight that showed up in the modeling is potential for the low temperature to occur a few hours earlier than normal as a warm front passes to our northwest. Wednesday: High pressure will move east of our region with a cold frontal boundary staying northwest of our region. Opted to side with the slightly warmer ECMWF, which should allow most places to get into the 40's for highs.
307 PM CDT Tue Apr 10 2018 Short term concerns include the threat for freezing rain and snow late tonight and Wednesday. With the Metro model forecasting road surface temperatures only briefly below freezing late tonight and Wednesday morning. Believe the freezing rain hazards will be reduced and will not issue an advisory at this time. Otherwise the wintry mix of freezing rain and snow will become a mix of rain and snow Wednesday afternoon. For Wednesday night there will likely be some freezing drizzle across teh north central and east.
An upper level ridge will be over the area tonight, but will shift eastward as an upper level disturbance moves across the state on Wed. There is just a slight chance that a few showers could occur over the higher elevations along the Continental Divide Wed afternoon, otherwise the weather will remain dry. Highs across the southeast plains will be in the 80s, but a little cooler in portions of El Paso county, and close to 90 near the eastern border. Afternoon humidities Wed should drop below 15 percent across most of southeast and south central CO, with mainly just the high elevations remaining above 15 percent. Thus, the combination of the strong winds, the low humidities and dry fuels will lead to Red Flag conditions and will leave the current Red Flag Warning as is.
318 PM CDT Tue Apr 10 2018 High pressure continues to filter into the region today from the NW, resulting in clear skies over our region. Temperatures will begin to fall overnight as teh region of high pressure becomes centered over us. Temperature should reach the lower to mid 70's area wide under clear skies.
Surface analysis this morning places a 1029 mb ridge of high pressure over the Central and Southern Plains this morning while a weak cold front has passed through the Mid-South.
S upper ridge will be translating eastward into CO this afternoon. Surface lee trof will deepen in response and should see westerly winds increase across the high country and along the lee slopes overnight.
359 PM EDT Tue Apr 10 2018 High pressure will bring dry weather to the region this evening, but cloudy skies will likely remain for many locations.
Freezing Temperatures Possible Tonight. Readings ranged from the mid 40s in the north to the lower 50s in the south. This will slide east to TN tonight as the upper trough axis swings east. The much anticipated warmup begins on Wednesday! High pressure shifts east as a low pressure system develops over the northern Plains.
High pressure moves across the area tonight with another trough of low pressure crossing the region on Wednesday.
241 PM CDT Tue Apr 10 2018 High pressure is currently in control of our weather and will be shifting to the east later tonight.

Temperatures today should still warm in the lower to mid 70s across the forecast area.
241 PM EDT Tue Apr 10 2018 High pressure over the Mid Mississippi and Ohio Valley will move southeast tonight and off the southeast coast by late Wednesday.
Lows tonight are expected in the low 40s with temperatures on Wednesday warmer than today.
With a moderating airmass and enough low level winds, minimum temperatures will remain well above freezing at lower elevations. With even more rise in thicknesses and warmer 700 mb temperatures, anticipate maximum temperatures soaring into the mid 60s to mid 70s at lower elevations. Another relatively mild night again in the warmer than normal airmass and with decent mixing helping to keep low temperatures above freezing at lower elevations.
There will be a few clouds around tonight as a weak upper trough drifts east across the Southern Appalachian region. The scattered to broken layer and a bit of a surface pressure gradient may be enough to keep temperatures a few to several degrees above the freezing mark overnight. Wednesday should be another decent day with mostly sunny skies as low level ridging builds across the area. This high pressure will be centered off the Carolina coastline, yielding weak/improving sly waa across the southeast. Meanwhile to the west, a potent upper system will move onshore leading to amplification of the overall pattern, specifically a deepening trough across the Rockies through the remainder of the work week.
120 PM EDT Tue Apr 10 2018 High pressure builds over the area tonight and Wednesday, then becomes centered off the coast through the weekend.
Temperature recovery will continue to be limited today as the Upper Ohio Region remains under the influence of broad upper trough. Broad high pressure is expected to keep weather dry tonight and Wednesday.
Wet weather will continue Wednesday as another cold front moves onshore.
A mid-level trough will dig into the state by Wednesday, allowing the front to begin progressing back south and east across the peninsula of Florida.
For tonight, not as cold compared to recent nights, have lows in the lower to mid 30s on average. Uttech Active weather pattern for the extended as warmer air is finally forecast to overtake the area. North of the warm front, temperatures still remain cold, this will lead to high baroclinicity across the area. Wednesday morning, zonal H5 flow will bring warmer air to the area and a weak wave to the area. Overall momentum fields depict a strong H5 trof and wave moving across the CONUS through the end of the week.
319 PM EDT Tue Apr 10 2018 High pressure will keep dry weather over the region tonight through Wednesday. Low pressure crossing the Great Lakes is forecast to provide a chance of showers to northern locations Wednesday night.

335 PM EDT Tue Apr 10 2018 High pressure builds over the area tonight and Wednesday, then becomes centered off the coast through the weekend.
255 PM EDT Tue Apr 10 2018 Low pressure will continue to move away from the North Carolina coast tonight.
On the backside of the high. Some scattered cumulus were developing on the eastern side of the high. shifting southeast with some scattered alto-cumulus/cirrus on the western side of the high.
The pesky front will shift south overnight as weak low pressure pushing into the Atlantic forces it down the peninsula. It will be noticeably cooler when heading out the door Wednesday morning with overnight lows in the upper 50s/low 60s expected. Highs will be slightly cooler than normal in the 70s for most areas, with overnight lows in the mid to upper 50s, except low 60s along coastal areas south of the Cape.
Remaining mid cloud deck should clear out of area by 18z as area of WAA ahead of short wave trough moves to the east. There will be weak lee side troughing.
Highs today with good insolation and downslope flow as the upper ridge builds east will be in the upper 60s to around 70.
A thermal ridge, at 850 mb, will expand, from the west, into West Central Texas today. This will help produce afternoon highs warmer than yesterday, especially with lots of afternoon sunshine.
The combination of westerly winds, warmer air, and partly sunny conditions will yield highs from the mid 30s in the Turtle Mountains, to mid 40s south central, and lower 50s southwest. BUFKIT soundings show a potpourri of precipitation types possible - light freezing rain, snow, and rain. Metro model road temperature forecasts indicate a few hour period for sub freezing temperatures late tonight into mid morning Wednesday. A wintry mix of light freezing rain and snow from the short term Wednesday morning will transition to rain along and west of the Missouri River, while rain/snow mix will exist east of the Missouri River. Before the precipitation exits the Turtle Mountains and northern James River Valley late Wednesday night, expect a transition back to light freezing rain potential as the column begins to lose ice aloft.
With continued northwesterly flow aloft and high pressure ridge not arriving until afternoon, forecast soundings suggest SCT-BKN diurnal cloud development from late morning into the afternoon. As the high shifts east of the region, mid/high clouds will quickly increase from west to east this evening. Thanks to the cloud cover and winds backing to the south, overnight lows will be warmer than in recent nights. ranging from the lower 30s near the Indiana border to the upper 30s across the southwest around Jacksonville.
It could be a little warmer, but we'll get that over the next 3 days. Winds will be light and generally out of the north as high pressure starts to move into the region.

Cooler and Cloudy Today. The combination of deep moisture in place and the formation of a weak coastal trough will continue to produce isolated to scattered showers for today, mainly along the coast. Rain chances will linger tonight and Thursday due to the weak coastal trough and low to mid level moisture. Temperatures will be below normal today due to abundant cloud cover and slightly cooler air filtering into the region. The cooler temperatures today will be short lived as above normal temperatures return for Thursday.
719 AM EDT Wed Oct 11 2017 High pressure will build south from Canada today. Low pressure will pass well south of New England tonight as high pressure continues to build over the region.
