Aikyam-Lab/Synoptic-Bench huggingface dataset:
Temperatures in the southwest should get a degree or two warmer while being held back in the northeast by cloud cover.
112 PM EDT Fri Mar 19 2021 High pressure builds into the area today and remains through the weekend. Gusty winds still expected for much of the day as high pressure tries to building in from the north.
252 PM CDT Fri Mar 19 2021 Current surface analysis places high over the Great Lakes, with trough to the lee of the Rockies. Upper level analysis places ridge to the lee of the Rockies nudging into the plains, with trough/low pushing over the west coast. Tonight, aforementioned trough pushes east, with ridge departing to our east. On Saturday, aforementioned cool front gradually works its way through the area through the day into the evening, while upper trough continues its approach. This will bring cooler temperatures to the northwest behind the front, warmer ahead.
1016 AM CDT Fri Mar 19 2021 (Issued 1016 AM CDT Fri Mar 19 2021) High pressure continue to settle into the Great Lakes Region this morning. Patterson (Issued 416 AM CDT Fri Mar 19 2021) Today through Saturday: Fairly strong high pressure will dominate through Saturday, keeping us dry and our skies clear. Highs today will reach the low 50s as ample sunlight allows us to warm up nicely, although there will be the possibility for a lake breeze today, which may hamper highs along the lakeshore.
131 PM EDT Fri Mar 19 2021 High pressure slowly building south across the area bringing with it crystal clear skies to all of Michigan this morning. A large expanse of upper level ridging was across the Plains and moving into the western Great Lakes. Saturday, for the most part, will look a lot like Friday, the only difference will be that the return flow will begin during the afternoon as the ridge axes moves to the east.
A little bit warmer on Saturday as well, with increasing southerly winds.
High pressure is in control at the surface with H5 ridging moving overhead west to east. With high pressure at the surface and aloft in control the next 24 to 36 hours expect favorable flying conditions across the region with VFR and light winds prevailing. /issued 301 AM CDT Fri Mar 19 2021/ SHORT TERM (Now through Saturday): 500mb ridge over the Rockies and Desert Southwest to slowly move east over Texas through the weekend. At the surface re-enforcing high pressure noses into region today remaining along the coast and the Western Gulf of Mexico Saturday. Both ridges continue to provide a very dry and stable atmosphere with mean layer 1000-500mb relative humidity to range between 25-40 percent as the dry northerly surface flow keeps dew points well below Deep south Texas norms.
245 PM CDT Fri Mar 19 2021 WV imagery shows the upper ridge has developed a bit farther east over the past 24 hours, resulting in cloudless skies over West Texas and Southeast New Mexico, and a slightly warmer afternoon than yesterday's.
Upper low/trough has shifted east of the Appalachians late this morning with cold front that was to the northwest now moved through the region. Newfound Gap temperatures was in the lower 30s this morning with some light snow likely occurring there and an inch of snow overnight on Mount LeConte. Upper low has moved east this afternoon but lingering low level moisture is slowly being scoured out by north to northeast winds.
1239 PM CDT Fri Mar 19 2021 Pleasant weekend still on tap as high pressure meanders eastward across the region, trekking from eastern MN this morning to the eastern great lakes late Sat night. With gusts touching 30 mph at times (moreso wind prone areas west of the mississippi river), warmer air pulled northward will push temps into the low 60s for some. The main shot of forcing/lift will come with a trough/closed low coming out of the desert southwest, driving over the mid mississippi river valley on Tue, gradually lifting northeast into southeast Canada late Wed night. High pressure slides across the region today, shifting across the eastern great lakes by Sat night. A lot of dry air accompanies the high, with the potential to mix down even drier air a loft - per bufkit soundings.
SW flow aloft will be over the area, as a weak lee trough develops by aftn, along the I-25 Corridor. The upper level ridge axis will shift east of the forecast area Saturday with increasing southwest flow aloft. This will bring gusty winds to the mountains, Palmer Divide, and eastern plains, and warmer temperatures to the entire forecast area. The warm and dry weather will come to a fairly quick end as a cold front and short wave trough move in from the west Saturday night.
231 PM EDT Fri Mar 19 2021 High pressure builds into the area today and remains through the weekend. Gusty winds still expected for much of the day as high pressure tries to building in from the north.
As low-lvl winds increase, could see some areas along the Buffalo Ridge gust up to 40 mph at times after midnight. Areas with deeper snowpack may drop below freezing.
Quiet weather is once again the highlight of the short term as high pressure dominates.
Continued sunshine and mixing into warmer mid-level temperatures will allow for highs to reach into the mid to upper 60s across much of the area tomorrow.
A cool and dreary day ahead, as current temperatures range from the low to upper 40s under gusty northerly winds. With the upper low now off the Atlantic Coast and a secondary cold front through much of northwest and north central AL, temperatures will remain a good 10 to 15 degrees below normal today, and thick cloud cover will limit diurnal heating. Look for highs in the low to mid 50s this afternoon. High pressure at the surface will continue to build into the area from the north tonight into Saturday. Dry air and strong subsidence from the area of high pressure should help to scour out cloud cover by Saturday morning. The end result will be a mostly sunny (and warmer) day, with winds veering to the SE, helping to push highs back into the 60s.
222 PM CDT Fri Mar 19 2021 222 PM CDT High pressure has established its presence across the entire Great Lakes region and into the northeast. Inland readings approach 50, though temperatures are some 10 degrees cooler lakeside.
/Today/ Clouds/moisture associated with a mid level trof axis continue to hold in over much of our region this morning. A low-level trough extending across much of the Deep South to maintain a 3-5kft cloud deck across southern Arkansas and north Louisiana through the late morning hours with gradual improvement expected this afternoon as weak ridging builds from the west. Otherwise, dry conditions to prevail through the short term period as an upper-level ridge across Texas and Oklahoma maintain subsident northwest flow aloft.
200 PM CDT Fri Mar 19 2021 An upper level ridge will continue to build over the area tonight with the ridge axis passing overhead early Saturday morning. Upper level winds will back to the west on Saturday with an upper level trough moving into the Intermountain West. The approach of the upper trough will allow for surface pressure troughing/cyclogenesis in lee of the Rockies on Saturday afternoon. The surface pressure gradient will tighten in response to this and will result in breezy southerly winds and warmer temperatures.
Initially, this has resulted in little change in diurnal temperatures which remain in the lower to mid 50s as we enter the afternoon hours.
1237 PM CDT Fri Mar 19 2021 (Today and tonight) As lower level ridge axis settles in over the region today and tonight, winds are expected to be much weaker than previous couple of days.
Lows tonight will be quite seasonable cold as high pressure influences to our north influence mid state weather pattern. Lows tonight will range low to mid 30s, and possibly even be below freezing across Upper Cumberland Region. It stills look like over this upcoming weekend that mid state will see an increase in temperatures as upper ridging works its way over our area.
Temperatures will be well-above average on Saturday with good mixing ahead of the front and a transitioning upper ridge.
313 PM CDT Fri Mar 19 2021 Plenty of sunshine is in store this weekend as high pressure slowly moves across the region.
141 PM EDT Fri Mar 19 2021 High pressure over the Great Lakes region will build south into our area tonight. The High center will wedge against the eastern face of the Appalachians for the weekend. High pressure over the Great Lake region this afternoon will slowly slide east tonight into Saturday. Low pressure will push further out into the Atlantic ocean. Gusty northeasterly winds in the wake of departing low pressure will diminish this evening into tonight. Saturday morning low temperatures will range from the mid 20s across the mountains to the lower 30s east of the Blue Ridge. The upper ridge builds over the Eastern CONUS Saturday. A classic strong wedge (1037mb ridge centered over the northeastern states) will wedge south into the panhandle of Florida Saturday night.
Pattern synopsis and forecast: Sprawling area of high pressure making slow progress south across the area this afternoon, as evident by sun-filled skies and relatively light winds. Of course, eastern upper and coastal areas will remain a bit cooler.
NE winds will increase tonight especially near the coast after 00z as strong high pressure to the north builds into the area. Mostly clear skies are expected Today with high temperatures ranging from the upper 60s across se GA to the lower 70s north-central FL. Cold front moves southeastward across the area Tonight. Cloudy and cool conditions are anticipated for the weekend with breezy winds from out of the north and northeast as high pressure presses southward from out of the north. A weak trough will move into the region from out of the northeast leading to slight chances for showers extending inland, with the highest chances for precipitation occurring along the coastline.
Previous forecast already trended high temperatures today on the cool side of guidance, and that still appears quite reasonable with hourly readings so far on track, if not starting to run a little cooler than forecast across Central LA. Other issue today will again be elevated nrly winds, but with CAA winding down and high pressure building over the region, speeds are not expected to be as strong as previous days. Areas inland with clear skies were the lower to mid 40s.
A weak upper level ridge over the southern Rockies into northern Mexico will move east into south Texas by Saturday night.
Winds stay up around 5 kts early Saturday, but sheltered valley locations may dip into the low to mid 20s. Ridging continues to build into the region on Saturday, and the weather looks beautiful.
237 PM MDT Fri Mar 19 2021 After a very warm and dry Friday, a dynamic weather system will bring wet conditions and cooler temperatures to the area Saturday, including some heavy wet snow to the high country.
At the surface, high pressure will dominate the region through Saturday, while aloft a ridge of high pressure will build over the region.
241 PM CDT Fri Mar 19 2021 A secondary cold front was located south of the forecast area, bringing a reinforcing shot of below normal temperatures and drier air to the Valley. High pressure will continue to move southeast over the Great Lakes region, but a wedge front could lead to isolated showers later this evening. A cool but very nice weekend will shape up over the Tennessee Valley, as high pressure and subsidence builds over much of the eastern US.
336 PM CDT Fri Mar 19 2021 High pressure has settled over the region today resulting in sunny skies, light winds, and mild temperatures.
An approaching trough of low pressure makes landfall on the Washington coast this evening, pushing moisture and cooler air ahead of it and into western Montana and central Idaho. Travel impacts for Saturday will be limited to wet roads in the lower elevations, and decreased visibility with some slush on mountain passes.
With clear skies and ridging, the forecast will lean toward the colder MOS, NBM (deterministic blend) and NBM ensemble probabilistic guidance.
High pressure over Oklahoma stretches down into the Big Bend and will be sliding east tonight and Saturday turning our winds more easterly.
As high pressure sets up to our north this weekend, an inverted trough will develop over the Gulf Stream off the east coast of Florida. Some upper-level energy will continue to progress across the state as upper-level troughing remains over the Southeast. Models respond by developing a weak low pressure area from the trough over the Gulf Stream and moving it slowly to the northeast. A plume of moisture between the high to our north and area of low pressure to our south will advect southwestward across the region on Saturday.
The region sits under broad troughing/northwest flow aloft and a tightened surface pressure gradient is in place helping keep northerly winds breezy. Models indicate some pocket of higher moisture(still not great) associated with this and given the presence of the upper trough nearby, won't rule out that there could be some drizzle/sprinkles/light rain.
227 PM CDT Fri Mar 19 2021 (Issued 227 PM CDT Fri Mar 19 2021) Tonight and Saturday: High pressure over the Great Lakes region will keep Wisconsin dry and skies clear through Saturday. If a lake breeze develops this will keep the lakeshore cooler than areas further inland. There will be some gusty southerly winds to accompany the lower RH values as well, which means if a fire starts it may spread quickly.
1219 PM EDT Fri Mar 19 2021 The center of large high pressure spread over the Great Lakes will settle slowly from northern lower Michigan across southern lower Michigan tonight. Winds will become light south southeasterly Saturday on the backside of the departing high pressure center. * None Area of high pressure will strengthen while building southeast across the region today running up against the trough of low pressure draped along the east coast. The axis of the high is elongated southwest to northeast and will be positioned over the straits this morning keeping a northeasterly wind going today. Mid level heights will be on the rise today as well as the longwave trough over the east coast shifts east.
337 PM EDT Fri Mar 19 2021 A cold front moved across the Florida Keys and a majority of our coastal waters today. Temperatures are currently in the upper 70s in the Lower and Middle Keys due to higher amounts of cloud cover, while the Upper Keys are seeing temperatures in the lower to mid 80s.
Upper low/trough has shifted east of the Appalachians late this morning with cold front that was to the northwest now moved through the region. Newfound Gap temperatures was in the lower 30s this morning with some light snow likely occurring there and an inch of snow overnight on Mount LeConte. An upper low continues to exit the region to the east this morning fostering light ra at TRI, with mainly MVFR levels at all sites, some scting at CHA. Meanwhile a cold front continues to approach from the north, set to sweep through the area this morning with gusty wly winds to veer nwly/nly behind the front.
There have been local variations in dew points, but the lowest readings have been across portions of northwest Minnesota (19F). Going into tonight, expect some of the higher end gusts to fall off, but sustained winds will stay up. Highs on Saturday should be a few degrees warmer than today, with 925mb temperatures a few degrees warmer.
most areas will drop below freezing after midnight with lows in the upper 20s.
129 PM EDT Fri Mar 19 2021 High pressure over the Great Lakes region will build south into our area tonight. The High center will wedge against the eastern face of the Appalachians for the weekend. High pressure over the Great Lake region this afternoon will slowly slide east tonight into Saturday. Low pressure will push further out into the Atlantic ocean. Gusty northeasterly winds in the wake of departing low pressure will diminish this evening into tonight. Saturday morning low temperatures will range from the mid 20s across the mountains to the lower 30s east of the Blue Ridge. The upper ridge builds over the Eastern CONUS Saturday. Quiet weather with temps just below normal through the start of Broad high pressure takes over the weather pattern this weekend, as a ridge forms over the eastern CONUS.
Dry weather is expected to continue Saturday and Saturday night as the latest run the HREF continues to show the upper ridge currently over High Plains will build into the area.
Tonight, a large 1035 mb surface pressure ridge eases eastward over the OH River Valley, Meanwhile, a weak wave of frontal low pressure begins to develop over the central FL Panhandle. There are indications in the short range guidance that a tap of Atlantic moisture in the evolving low level northeasterly flow will be forced by a southwestward propagating surface trof over the southeast US. This trof extends northwest, out from the FL frontal low. With a weak surface pressure trof slipping westward, a small chance of light rain will be introduced over the Gulf waters on Saturday with any rain amounts there being light as well.
1220 PM CDT Fri Mar 19 2021 (Today and tonight) Cool high pressure centered across much of the Great Plains and central Texas will continue to be the dominant feature for the next 24 hours.
An upper ridge will track eastward across the Panhandles tonight and Saturday and then move off to the east Saturday night. An upper trough will approach the Panhandles from the western states Saturday night. Warmer and dry conditions tonight through Saturday night.
SHORT TERM (Now through Saturday Night): High pressure is in control at the surface and H5 ridging will move overhead west to east in the short term. A return to near normal temperatures will have to wait until southeast winds become reestablished just after the short term period when high pressure reorients farther east.
Cloudy, cool and breezy conditions continue today as the affects of the upper trough linger over the area. Cyclonic flow on the western periphery of the upper level trough anchored to our east will maintain the cold advection pattern and associated stratus.
Lingering low to mid level moisture/lift in association with a low pressure center to our e has continued to hold clouds in over much of the area this aftn. Upper ridge axis bisecting extending up through the Great Plains will amplify ewd Saturday. The region will remain under the influence of sfc ridging to our ne, making for pleasant, albeit cooler than normal, early spring conditions through Saturday night.
321 PM CDT Fri Mar 19 2021 This afternoon an mid level ridge was present over the Rockies and into Montana while a mid level trough was over the eastern Pacific and approaching the northwest coast of Washington. On Saturday the mid level ridge will move over eastern Kansas while a deepening lee side trough develops a tight pressure gradient across western and into central Kansas. Expect highs in the low to mid 60s with afternoon RH dropping down to around 30 percent.
302 PM EDT Fri Mar 19 2021 A strong low to mid level anticyclone now centered over Wisconsin will move over srn Lower MI tonight before advancing to the Mid Atlantic and New England by the end of the weekend. The airmass circulating around the high will remain extremely dry. Broad upper level ridging across the Great Lakes will keep even high clouds at bay.
302 PM CDT Fri Mar 19 2021 222 PM CDT High pressure has established its presence across the entire Great Lakes region and into the northeast. Inland readings approach 50, though temperatures are some 10 degrees cooler lakeside.
1040 AM CDT Fri Mar 19 2021 The Mid-South remains underneath an upper trough this morning. Highs will only be in the low to mid 50s. High pressure will build into the region for the weekend and a warming trend will begin this weekend.
313 PM EDT Fri Mar 19 2021 The broad and vertically-stacked ridge of high pressure that has quickly built into Indiana today will continue to provide dry and clear conditions through Saturday night. before winds quickly diminish early this evening as the center of the ridge settles closer to the region.
/issued 1040 AM CDT Fri Mar 19 2021/ The Mid-South remains underneath an upper trough this morning. Highs will only be in the low to mid 50s. High pressure will build into the region for the weekend and a warming trend will begin this weekend.
1241 PM EDT Fri Mar 19 2021 High pressure builds into the area today and remains through the weekend. Gusty winds still expected for much of the day as high pressure tries to building in from the north.
Temperatures will be seasonably cooler through the weekend with the chance of showers over the Cascades and much of north Idaho.
459 PM CDT Fri Mar 19 2021 Low pressure system will move off the eastern seaboard through tonight. High pressure will build in over central Texas through the weekend. Mixing will begin to occur by Saturday afternoon as upper level ridging and subsidence will allow for a rapid decrease in clouds.
625 PM CDT Fri Mar 19 2021 High pressure will continue to build over Arkansas tonight with clear skies.
959 PM EDT Fri Mar 19 2021 Updated 955 PM EDT Fri Mar 19 2021 Temps falling slowly this evening with NE breezes still up around 10 mph, but still expect winds to continue to diminish and temps to drop to around freezing, if not a bit below. Winds stay up around 5 kts early Saturday, but sheltered valley locations may dip into the low to mid 20s. Ridging continues to build into the region on Saturday, and the weather looks beautiful.
SE TX is the exception where more sun has allowed readings to warm into the lower 60s. The upper trof responsible for the cloud cover is progged to only slowly sink off toward the SE over the next couple of days, though the MSTR envelope will largely be shoved out of the area by tomorrow night. High pressure at the SFC and aloft will prevail on SUN, with a modest warming trend in temperatures continuing. The trof is forecast to eject out across the Central Plain/Mid MS River Valley MON night into TUE, dragging a weak SFC front into the forecast area, and bringing a good chance of showers and thunderstorms MON night through TUE, with the boundary stalling over the NW Gulf TUE night. Otherwise, high pressure will continue to build across the area through Saturday.
/issued 459 PM CDT Fri Mar 19 2021/ Low pressure system will move off the eastern seaboard through tonight. High pressure will build in over central Texas through the weekend. Mixing will begin to occur by Saturday afternoon as upper level ridging and subsidence will allow for a rapid decrease in clouds.
933 PM CDT Fri Mar 19 2021 (Issued 933 PM CDT Fri Mar 19 2021) High pressure solidly over the region this evening with just ever so slight breezes. Clear skies and calm winds tonight will allow temps to drop pretty quickly tonight and have nudged lows down a tad putting values in the lower 20s. Not out of the question for a few teens to occur in a few of the favored cooler spots. Stumpf (Issued 227 PM CDT Fri Mar 19 2021) Tonight and Saturday: High pressure over the Great Lakes region will keep Wisconsin dry and skies clear through Saturday. If a lake breeze develops this will keep the lakeshore cooler than areas further inland. There will be some gusty southerly winds to accompany the lower RH values as well, which means if a fire starts it may spread quickly.
A moist cold front moves across Nevada tonight and Saturday.
601 PM CDT Fri Mar 19 2021 Plenty of sunshine is in store this weekend as high pressure slowly moves across the region.
Elsewhere, temperatures should fall only a few more degrees into the lower 40s. A cool but very nice weekend will shape up over the Tennessee Valley, as high pressure and subsidence builds over much of the eastern US.
600 PM CDT Fri Mar 19 2021 High pressure has settled over the region today resulting in sunny skies, light winds, and mild temperatures.
Cooler and windier weather return over the weekend.
