Aikyam-Lab/Synoptic-Bench huggingface dataset:
325 AM EDT Wed Apr 11 2018 Cool high pressure will extend across the middle Atlantic region Wednesday, before transitioning off of the North Carolina Coast into Thursday.
340 AM CDT Wed Apr 11 2018 Upper level ridging currently over the Rockies will continue to flatten and provide nearly zonal flow over the area today. Quite a few high clouds have been spilling down the ridge and over the Central Plains and despite these high clouds today, favorable winds for mixing should allow highs to reach into the 70s across our north to around 80 across our south. Another warm day is expected Thursday with slightly cooler highs over northeast Nebraska behind the above mentioned cool front. Meanwhile, a large upper level trough will be moving across the western states with a lee cyclone strengthening over the High Plains region.
The upper-level eastern CONUS trough will swing through the Tri- State region overnight, ushering in drier air aloft. Deep layer high pressure will build in behind today's departing system yielding dry conditions and seasonal temperatures across the tri-state region.
330 AM EDT Wed Apr 11 2018 Mostly cloudy, breezy and warmer conditions are expected today with highs in the upper 50s to near 60 degrees.
The above noted area of high pressure should move across the area during Wednesday. A southerly flow around this high, and a developing storm system east of the Rockies will progress eastward, and make for an unsettled upcoming weekend.
More widespread rain is forecast for Thursday as a warm front moves through the region. Highs will range from the lower 40s in the western Catskills to upper 40s in the valley areas of northeast Pennsylvania. Low pressure will track from southern Lake Michigan to northern New York State. The warm front associated with this system will lift up through the area bringing more widespread rainfall to central New York although the far southeast areas may see very little. Rainfall will be generally a half inch or less with the higher amounts in the northern areas. A cyclone will track through the Great Lakes and into Northern New York Thursday night, spreading showers across much of the region, especially north of the NY/PA border.
Under mostly to partly sunny skies, expect highs to reach the low to mid 60s over southern IN/central KY this afternoon. This strong southerly flow will push high temps into the low to mid 70s.
335 AM CDT Wed Apr 11 2018 A cold front will approach the Northland today with increasing clouds this afternoon. Meanwhile a developing low pressure system will approach southern WI ushering in a moisture feed from the south. That will be fleshed out a little better when the higher rez models latch on to this event. Impact-wise the timing is good for the most part, but the Thursday morning commute may be impacted by the freezing precip overnight tonight. The focus is on what continues to look like the potential for significant snow and freezing rain, and generally unseasonably winter-like weather, late this week.
120 AM EDT Wed Apr 11 2018 High pressure will bring dry weather to the region this evening, but cloudy skies will likely remain for many locations.
Today's highs will feel slightly warmer than yesterday with most places seeing the upper 60s.
Lows tonight are expected in the low 40s with temperatures on Wednesday warmer than today. Temperatures: A cold front will move through Wednesday night and lift back to the north during the day Thursday.
317 AM CDT Wed Apr 11 2018 Ridge of high pressure currently extending from the Ohio River Valley to Texas will continue to shift eastward today. Low pressure tracking from Nebraska this afternoon to northern Lake Michigan by Thursday morning will remain north of central Illinois. Due to continued strong southerly winds south of the low track, overnight lows will be considerably warmer than they have been in recent nights. with readings remaining in the lower to middle 50s. Breezy and even warmer weather will be on tap for Thursday, as high temperatures soar into the 70s.
VFR conditions to prevail tonight through Wednesday with mid level high pressure building over South Texas. Drier and more stable air will continue filtering into the RGV from the north as the cold front that moved through the region last night pushes to our south. This will allow the clds to clear out later this evening and tonight with more sunny skies prevail tomorrow and tomorrow night as surface and mid level ridging builds over the area. The surface ridging will be building to our east tomorrow which will allow the warmer and moister SE low level flow to return which in turn will combine with the increasing sunshine to allow the temps to warm steadily.
Cold front continues to move slowly east this evening. This cold front will move across the region in the afternoon and evening with a period of rain and mountain snow. Cold upper level trough overhead Thu with -32C temps at 500mb. Cold front moving through Wed with rain overspreading the taf sites mainly in the afternoon.
655 AM EDT Wed Apr 11 2018 Mostly cloudy, breezy and warmer conditions are expected today with highs in the upper 50s to near 60 degrees.
422 AM CDT Wed Apr 11 2018 An area of low pressure will track southeastward across the region today through tonight.
1236 AM CDT Wed Apr 11 2018 VFR and gradually breezier through the period, as a low amplitude upper level ridge axis passes overhead early Wednesday with zonal westerly flow following. Still expect the low level jet to strengthen overnight - though delayed the start of LLWS remark at KCDS until 09Z. For Thursday we'll see winds increase further and warmer temperatures for many locations than what will be realized tomorrow.
340 AM CDT Wed Apr 11 2018 It's been a much warmer night than what we've experienced over the past 10+ days with temperatures in the 30s and 40s. Southerly winds and the advection of a more moist, spring air mass are responsible for the above freezing temperatures.
414 AM CDT Wed Apr 11 2018 System that will impact the area today is coming across the Rockies, with a broad area of moisture and cold cloud tops showing up on satellite imagery moving out across the High Plains.
615 AM EDT Wed Apr 11 2018 Cool high pressure will extend across the middle Atlantic region Wednesday, before transitioning off of the North Carolina Coast into Thursday.
148 AM EDT Wed Apr 11 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.
Low pressure from the Great Lakes region will approach from the west on Thursday and cross the region Thursday night.
414 AM MDT Wed Apr 11 2018 Current surface analysis shows low pressure over northwest MT, with warm front extending southeastward across MT into SD. A large trough sits off the Pacific NW coast. Another very mild day is on tap, especially from northeast WY to southern SD, as warm front remains across northwest through southeast SD through the early afternoon. Breezy west to northwest winds will develop toward the afternoon as the low passes over and east of the area.
422 AM CDT Wed Apr 11 2018 It's been a much warmer night than what we've experienced over the past 10+ days with temperatures in the 30s and 40s. Southerly winds and the advection of a more moist, spring air mass are responsible for the above freezing temperatures. Uttech Thursday A warm front is forecast to develop over southern Iowa into west- central Illinois in response to strong cyclogenesis in eastern Colorado (~982mb low). There is uncertainty as to how far north the warm front moves which will impact high temperatures.
456 AM EDT Wed Apr 11 2018 High pressure, warming, and drying into the weekend.
546 AM CDT Wed Apr 11 2018 Upper level ridging currently over the Rockies will continue to flatten and provide nearly zonal flow over the area today. Quite a few high clouds have been spilling down the ridge and over the Central Plains and despite these high clouds today, favorable winds for mixing should allow highs to reach into the 70s across our north to around 80 across our south. Another warm day is expected Thursday with slightly cooler highs over northeast Nebraska behind the above mentioned cool front. Meanwhile, a large upper level trough will be moving across the western states with a lee cyclone strengthening over the High Plains region.
High pressure during this afternoon should provide a short period with decreased cloud cover, but the next weather system arrives this evening. A cold front passage during Thursday morning is likely to quickly lower snow levels to around 2000-2500 feet, so rain will change to snow for most. Raised surfaces, such as bridges and overpasses, have the highest potential for slick surfaces during Thursday morning.
345 AM CDT Wed Apr 11 2018 A nearly picture perfect day in store across the region today as high pressure has become centered nearly directly overhead. The high will begin to shift off to the east by this afternoon, but with the exception of a few more clouds and slightly higher humidity, Thursday will be very pleasant as well.
As far as the light freezing rain threat, road temperatures both in real time and from the METRO forecast are to remain above freezing due west of Bismarck through Wednesday morning - so not really concerned with any freezing rain threat here. However, below freezing road surfaces are forecast from Ray to Newtown, and from Coleharbor to Washburn until 8AM-9AM CDT. It will be a close call as to whether or not the timing of precipitation and below freezing road surface temperatures coincide.
429 AM CDT Wed Apr 11 2018 Quiet weather expected for the next couple days as the upper trough to the east lifts out of the area and weak ridge passes overhead.
Scattered showers and isolated thunderstorms continue along a weakening cold front. The convection extends from Baker County east into the Lower Treasure Valley and west central Idaho mountains. Shower coverage will increase tonight ahead of a cold front and lagging upper trough. Showers will continue in the afternoon associated with the upper trough, along with a slight chance of thunderstorms. Winds will increase considerably on Thursday as much cooler air pushes into the area behind the front.
While convection allowing mesoscale models try to develop showers near the shore tonight, forecast soundings keep dry air in place in the low levels, so will keep land areas precipitation tonight. Mostly cloudy skies and milder temperatures are anticipated tomorrow ahead of a low pressure area that will pass through southern Wisconsin Wednesday night. On Thursday mid level ridging will set in bringing dry weather. Warm air advection will allow temps to get in the lower 60 to lower 70s, south.
459 AM EDT Wed Apr 11 2018 High pressure, warming, and drying into the weekend.
/Issued 637 PM CDT Tue Apr 10 2018/ For the 00Z TAFs, southwest winds will diminish early this evening, then ramp up again and become gusty by mid morning Wednesday as an area of low pressure develops across the central and southern high plains.
While parts of the northern zones could have a period of light mixed precipitation this morning with temperatures near freezing, the main band of rain will be across the southern zones this morning as most of the moisture stays to the south of the Missouri River. An upper trough moves inland from the Pacific tonight and Thursday. Upper trough moves into Montana and Wyoming Thursday Night with a closed upper low forming over Wyoming.
/issued 353 PM CDT Tue Apr 10 2018/ Pleasant temperatures today will give way to warmer conditions Wednesday and Thursday as west winds increase. This will occur as an upper level ridge currently over the western U. moves east and a low pressure system moves in from the eastern Pacific and into the Central Rockies.
SHORT TERM (Today through Thursday): The Atmosphere over Deep South Texas is very dry and stable with Surface and Mid level ridge overhead. Temperatures Thursday morning will be about 10 degrees warmer, mid 60s to near 70, with southeast winds becoming well established and the patchy low clouds keeping the low layers well mixed eliminating any radiational cooling affects.
218 AM EDT Wed Apr 11 2018 High pressure builds over the local area today, then becomes centered off the southeast coast through the weekend.
351 AM EDT Wed Apr 11 2018 A cold front is currently draped from Southwest Florida through the Space Coast into the Atlantic Ocean. Radar shows a line of showers that has developed along a trough ahead of the front stretching from the Treasure Coast into Naples.
324 AM EDT Wed Apr 11 2018 High pressure is centered over south central Kentucky this morning, with mainly clear skies being observed across most of the state. This has allowed temperatures to plummet into the low to mid 30s areawide. With high pressure in control today, expect a sunny day as temperatures climb into the 60s this afternoon. As the high exits east tonight into Thursday, return flow will set up across the region with heights on the increase. This will send much warmer weather northward across the Ohio river valley. Lows in the eastern valleys should still reach into the mid to upper 30s tonight with a nice ridge to valley split setting up. A strong ridge of high pressure is forecast to remain in place over the region for the next several days.
Temperatures will then warm to well above normal levels Thursday just ahead of a strong cold front that will sweep across the area late Thursday and Thursday night.
Afternoon temperatures were running at or slightly cooler than yesterday. Above normal high temperature will continue through the end of the week with upper high amplifying over the west coast. To our east an upper level trof will be deepening across the middle past of the CONUS. This will allow weak weather systems riding over top the west coast ridge to move down the back side of the ridge and gradually bring cooler temperatures to the region by the weekend.
A fast moving cold front will move southward through the region Wednesday night, producing some scattered rain and snow showers across Central Montana.
223 PM PDT Wed Oct 25 2017 On Thursday the high will weaken its grip and cool temperatures to above normal for the rest of the week. Expecting it to be about 5-10 degrees cooler at Dodger Stadium at first pitch this afternoon. As stated before, the heat is a result of the abnormally high pressure over the state coupled with the Santa Ana winds which effectively turn off the natural air conditioning from the sea breeze. The lowering heights will bring gradual cooling to the entire area and the weakening offshore flow will bring more cooling to the coastal sections.
137 PM EDT Wed Oct 25 2017 Cool temperatures and scattered shower chances will continue today under a broad upper low.
In spite the the cold conditions tonight, it appears that the area is in for a day of warmer temperatures on Thursday as southerly winds increase ahead of an area of low pressure shifting towards the Dakotas. This should allow a thermal ridge to advect east- northeastward over the area during the day. Therefore, high temperatures Thursday are likely to be several degrees warmer than they are today. Currently we expect temperatures on Thursday to top out in the upper 50s northeast, to the lower 60s southwest.
401 PM EDT Wed Oct 25 2017 High pressure is building in behind the first cold front of the season to clear South Florida.
Weak high pressure will be responsible for our dry weather today and tomorrow.
1107 AM MDT Wed Oct 25 2017 Upper air analysis shows deep trough continuing across the eastern CONUS. with strong ridging over the western half of the country. Warm air advection has begun at the low levels as a thermal ridge centered over the northern Rockies continues its eastward slide. Models continue to show a strong cold front pushing through the region tonight. Model runs from 00z have generally weakened winds slightly, but wondering how the 12z models will respond with the upcoming round of upper air launches and if the areal coverage of the High Wind headlines will need to be adjusted. Upper ridging will rebuild over the region bringing quieter weather to the CWA.
As surface ridging slides east tonight, light west to northwest winds 10 knots or less will gradually back to the southwest or south. Expect south to southwest winds to increase by tomorrow morning to 10-15 knots as the surface pressure gradient tightens ahead of a cold front.
A weak low pressure system diving southeastward across Minnesota this morning will bring warm temperatures into the CWA. Several locations this morning are reporting temps in the upper 40s to the lower 50s.
1134 AM MDT Wed Oct 25 2017 Active weather in the short term as a strong cold front moves through the area over the next 24 to 36 hours. Winds are picking up across our wind prone area with Arlington reporting wind gusts in the low 30mph range, Bordeaux around 30 mph and the south Laramie Range in the mid 30s this morning. Believe this will be the time for the strongest winds across our wind prone areas, so will keep the High Wind Warnings going. The front looks to sag southwestward across the area after 06Z with 700mb temperatures falling well below freezing by 09Z.
233 PM MDT Wed Oct 25 2017 Currently, a ridge aloft is pulling in warmer and drier air into the region.
328 PM EDT Wed Oct 25 2017 The low continues to shift E while weakening today. These showers will diminish through the day as surface ridging moves in, with only some light snow accumulations are expected over interior western Alger County. Low pressure system that brought strong winds and rain/snow to the area is well to the east now. Could see more snowfall late this week as another low pressure system impacts the Upper Great Lakes. Lake enhanced snow will continue at times later Fri night into Sat with sufficient over-water instability and persistent ENE-NNE low-level winds as the low weakens/fills while lifting toward Hudson Bay and northern Quebec.
Lows tonight will be much warmer than last night with the southwesterly winds, bottoming out in the middle 40s to lower 50s. Highs tomorrow will be back into the lower to middle 80s with mostly sunny skies continuing. The next system will move through the central plains Thursday and will send another cold front into the region Thursday night. This upper low will be much stronger and will send the coldest front of the winter season into Texas.
558 PM CDT Wed Oct 25 2017 A weak trof of low pressure is moving across the forecast area this afternoon. The surface reflection of this wave will move into Minnesota by late Thursday afternoon and the cold front associated with the system will push into northwest Missouri by 18Z and further into central and northeast Missouri and west central Illinois by late afternoon. Warm south-southwest flow and plenty of sunshine ahead of the cold front will produce a good warm up in the afternoon to well above normal temperatures in the low to mid 70s. Ridging builds in Wednesday in advance of the next trof that is diving south.
/issued 253 AM CDT Wed Oct 25 2017/ The upper trof currently over the Mid-South will move east today. The combination of the southerly winds, upper ridging, and strong warm air advection will allow temperatures to quickly rise on Thursday. Mild conditions will occur Thursday Night ahead of an approaching cold front. Lows will be in the lower to mid 50s.
A cold front will enter northwest Oklahoma midday tomorrow and could cause winds to shift to the northwest before 18z at GAG/WWR. Southwest winds will continue into Thursday ahead of a strong cold front. The strong cold front will bring colder and drier air to the region.
Much drier air has advected into the area behind cold front with dew points now in the upper 30s-40s and mostly clear skies across much of EC FL at mid afternoon. With clear skies and relatively light northerly winds, overnight mins will drop into the upper 40s-lower 50s across much of EC FL, with a few normally cooler interior spots falling into the mid 40s. High pressure will remain over the region, with continuation of dry and relatively cool air mass.
The amplified upper level trough over the region today will lift northeast and away from us overnight. This ridge will build eastward overnight with highest pressure over our forecast area by daybreak.
Main story through the weekend will be the continuation of dry weather and above normal temperatures as high pressure remains in control over the region. Daytime temperatures will cool a few degrees from Thursday to the weekend as ridge weakens slightly, but will still be on the warm side with highs in the 80s in the valley and 60s to 70s across higher elevations.
A highly amplified pattern exists across North America this morning with a deep trough axis just west of the forecast area. This is a chilly air mass that allowed temps to plunge into the lower to mid 40s across many inland areas for the first time this season.
As the base of the deep upper level trough parked overhead continues to shift east of the area this evening, northwest flow will prevail across the area. Lows tonight will range from freezing to the upper 30s; 5-10 degrees below normal for this time of year. Combined with higher heights aloft, temperatures will be slightly warmer tomorrow; topping out in the lower 60s across the valley and the mid to upper 50s elsewhere.
the main story of the forecast is the upper trough bringing spokes of energy thru the Ohio Valley. Another vort max will dive south along the back side of the upper level low over Lake Gitche Gumee.
An upper level trough and associated surface frontal system is moving down the PacNW coast this afternoon.
This will lead to a nice warm up with highs in the low to mid 70s over much of the region.
A weak cold front is moving east through the CWA with temperatures in the 70s out ahead of it, with 60s behind it.
The combination of ridging along the Lower Texas Coast and a low center in Eastern Colorado will persist through tonight, enabling a light southwesterly wind flow overnight. Aside from some weak warm advection, this should create enough stir to keep temperatures a good 8-10 degrees warmer than this morning's readings. Bradshaw /Thursday through next Wednesday/ The brief warm-up will be in full swing on Thursday ahead of the next cold front. A deepening trough across the middle part of the CONUS will send a strong cold front south of the Red River Thursday evening and through the rest of North and Central Texas Thursday night.
215 PM MDT Wed Oct 25 2017 Upper ridge covers the western CONUS, and a deep trough continues to dig into the east coast. Strong upper wave will push into the northern plains tonight with a cold front, bringing strong winds and some rain/snow showers.
254 PM EDT Wed Oct 25 2017 As the upper level trough shifts into the Mid-Atlantic coast, dry northwest flow aloft will set up tonight with nearly zonal flow tomorrow and tomorrow night.
The TN Valley will remain on the western periphery of a fairly amplified upper trough, with high pressure at the surface. On Thursday, with the ridge and southerly flow across the region, warmer temps return! Looking at daytime highs in the upper 60s/lower 70s and overnight lows around 50. The ridge is quickly pushed east by a large trough swinging across the Midwest, however you are still able to end the work week with daytime temps in the 70s too.
234 PM EDT Wed Oct 25 2017 A strong upper level trough will move across the region with clouds and some showers, especially west of the Blue Ridge, through tonight. High pressure will then build over the southeastern part of the country with fair weather and moderating temperatures expected through the end of the workweek.
328 PM CDT Wed Oct 25 2017 Strong winds still on target to arrive across central South Dakota Thursday morning, then spread east through the CWA through mid to late morning as the strong cold front moves through. Low pressure track is fairly similar to previous model runs, bringing the bulk of snowfall to eastern ND and MN. Decided to include the entire CWA in a Wind Advisory, but left a portion of the High Wind Watch in place over the Coteau region into west central MN, where 925/850 mb winds, along with 0.
