Aikyam-Lab/Synoptic-Bench huggingface dataset:
1109 PM MDT Fri Oct 21 2022 Potent upper trough beginning to dig into the western CONUS as semi-active easterly flow continues over the Northern Plains. This will support breezy SW winds south of the warm front into NE WY and southern SD, along with mild and dry weather Sat. Long wave upper trough will slide east Sat night with the sfc cold front entering the western FA. Forecast models have started trending more toward a split wave as the southern end of the trough digs and the northern portion advances NE into southern Canada.
232 AM CDT Sat Oct 22 2022 The boundary which sank southward into our northern areas last evening, as become stationary and may already be lifting northward along the Highway 30 corridor early today.
(Today through Sunday) Early this Saturday morning, temps were much warmer than the past several mornings, with most locations in the 50s. Deep southwest flow and a building upper ridge will keep the warming trend going this weekend with highs mostly in the 70s and lows mostly in the 50s.
Wind speed will be a bit stronger today, and already seeing a few gusts near 40 mph at ridgetop level across SE OK.
Latest obs across the area are reporting temperatures in the low to mid 30s across the interior where there is sufficient radiational cooling, while temperatures near the lakeshore are trending in the upper 30s to 40s. Weak ridging and WAA will overspread the UP today ahead of a strengthening Pacific Northwest trough.
Snow levels approach lower valley floors across western Montana tonight into Sunday morning as a weak cold front pushes in from the north.
542 AM EDT Sat Oct 22 2022 The weekend will remain warm and dry under a ridge of east coast high pressure. A beautiful day for the Upper Ohio Valley and Allegheny Mountains is about to get underway as plenty of sunshine coupled with warm air advection will result in considerably warmer conditions. With another night of optimal radiational cooling expected, look for temps to quickly drop, eventually reaching the lower 40s and upper 30s before daybreak Sunday.
An upper ridge aloft will keep building over the area warming temperatures today into the upper 60s to as warm as mid 70s.
Baker (Today through Sunday) As the last lingering piece of upper trough energy cuts off to the east and phases with some Atlantic moisture, the low should stay off the coast tracking north near the mid-Atlantic region by Sunday and allow for a continued dry ridge dominated regime for the CWA through this weekend. Temps look to continue to moderate warmer and highs today should make it to about a degree or so below climo with many locations in the low 70s. Lows tonight will still have some decent radiational cooling but will be warmer than past days and should stay in the 40s without any frost/freeze concerns.
730 AM EDT Sat Oct 22 2022 (Today through Sunday) South Florida remains located between an area of high pressure centered over the Gulf and a trough over the Atlantic waters. The low being to the northeast of the area will allow drier air to be reinforced over the region as it wraps into the low aloft. On Sunday, the low will begin a northward progression towards the Carolinas and mid-Atlantic coast.
330 AM PDT Sat Oct 22 2022 A deep Great Basin trough will bring clouds and showers over and west of the mountains today and tonight.
Highs should reach the upper 70s in parts of southern Wisconsin with a chance for a few spots hitting the low 80s. Winds will be more from the south than southwest though, which will result in a chance for somewhat cooler temps in lakeshore areas. Temps will remain mild tonight with the low level jet sitting overhead, with lows 15-20 degrees above average values for the second half of October.
Temperatures are currently in the low to mid 60s are still expected to top out in the 70s.
Today while a trough of low pressure remains well offshore. A broad high pressure lays to the north and west while an inverted trough sits to the east.
The boundary which sank southward into our northern areas last evening, as become stationary and may already be lifting northward along the Highway 30 corridor early today.
549 AM CDT Sat Oct 22 2022 Today and Tonight: Continued dry with warmer than normal temperatures through the period. The gusty south wind along with near full insolation will help temperatures top out from the upper 70s east to the lower 80s west again. The increased moisture will help keep temperatures mild overnight with lows Sunday ranging from the lower 50s east to near 60 degrees west. /22/ Upper ridging will build across the region from the south for the end of the weekend and into the beginning of the work week.
410 AM CDT Sat Oct 22 2022 Today and Tonight: Continued dry with warmer than normal temperatures through the period. The gusty south wind along with near full insolation will help temperatures top out from the upper 70s east to the lower 80s west again. The increased moisture will help keep temperatures mild overnight with lows Sunday ranging from the lower 50s east to near 60 degrees west. /22/ Upper ridging will build across the region from the south for the end of the weekend and into the beginning of the work week.
Temperature observations showed morning lows ranging from the lower 40s north to the lower 60s south. The daytime maximum temperatures are forecast to peak into the lower 80s this afternoon. Minimum RH values will range from the lower 40s to the lower 50s today. Mostly clear skies and rain free over the coastal waters as an area of high pressure continues to stretch over the waters.
Wind speeds will also increase late this morning through this afternoon with increasing lee pressure falls ahead of a tightening mid level gradient over the Rockies and digging upper trough.
Drier air continues to inch eastward as a trough of low pressure slowly rotates over the Atlantic waters.
Today through tonight: Flow gradually tilts further southwest to south as the trough to the west amplifies. Freezing rain chances have quickly evaporated with this event, as surface layer and ground will not be cold enough to allow for contact freezing in the transition from rain to snow.
231 AM PDT Sat Oct 22 2022 Cooler temperatures and breezy conditions expected this weekend. Breezy west/northwest winds today in the Valley will gust to around 15 to 25 mph, and west/upslope mountain gusts upward to 40 to 60 mph (strongest at peaks/ridgetops). As the upper-level trough passes east, winds will become offshore (north/east) for the second half of the weekend, which will promote a downward trend in relative humidity values.
As a leeside trough takes shape to our west, the surface pressure gradient will continue to tighten. /DL/ Today and Tonight: Continued dry with warmer than normal temperatures through the period. The gusty south wind along with near full insolation will help temperatures top out from the upper 70s east to the lower 80s west again. The increased moisture will help keep temperatures mild overnight with lows Sunday ranging from the lower 50s east to near 60 degrees west. /22/ Upper ridging will build across the region from the south for the end of the weekend and into the beginning of the work week.
717 AM EDT Sat Oct 22 2022 Aviation -- Continued warm, sunny, and breezy into Sun -- A lee cyclone in the high plains will deepen today and tonight, then emerge into the northern plains on Sun. Southerly low-level flow within the broad/expanding warm sector east of this cyclone will maintain warmth over the region through the weekend. The emerging consensus--also shown in the deterministic ECMWF and GFS solutions--is that a deep trough over the southern Rockies will phase on Sun night with a trough that will cross the Baja Peninsula earlier Sun evening. On Fri, EPS/GEFS means suggest that another prominent trough will emerge from the Rockies, providing the next chance of precip for Fri and beyond.
614 AM CDT Sat Oct 22 2022 (Today through Sunday) Early this Saturday morning, temps were much warmer than the past several mornings, with most locations in the 50s. Deep southwest flow and a building upper ridge will keep the warming trend going this weekend with highs mostly in the 70s and lows mostly in the 50s.
621 AM CDT Sat Oct 22 2022 (Today and tonight) Above normal temperatures are expected again today across West Central Texas, as weak upper level ridging dominates the region.
618 AM CDT Sat Oct 22 2022 (Now through Sunday) The pressure gradient along the lower Texas coast tightens this weekend as a ridge of high pressure along the East Coast builds and low pressure across the Rockies and Plains deepens. Hurricane Roslyn is expected to make landfall along the west-central coast of Mexico late tonight or early Sunday, quickly losing steam as it runs into the higher terrain of Northern Mexico.
High pressure centered to the northeast of Bermuda reaches southwest into the northern Gulf of Mexico. A inverted trough near the northern Bahamas has carved out a divot in the high's southwestern flank.
1234 PM PDT Sat Oct 22 2022 A trough of low pressure entering the Great Basin will lead to significantly cooler temperatures today, along with gusty winds in wind-prone areas of Central California. A cold front dropping southward through the area will bring much cooler temperatures and gusty winds for our southern zones this afternoon. Precipitation will be very minimal for this passage with a light dusting of snow, if any for the higher peaks of Sequoia National Park and National Forest. Winds this morning have already reached 50-64 mph through some of the higher elevations of Sequoia National Forest with HIRES guidance showing winds to increase during the late afternoon hours as FROPA occurs. After this system pushes through things will quiet down a bit with dry conditions and cooler temperatures.
Cold front passed through the region this afternoon. Some light precipitation will arrive tonight and Sunday as closed upper low passes through east Idaho. Elevations above 5500 feet could see an additional 1 to 3 inches with up to 6 inches possible on the highest peaks in the Wasatch, along the Montana border near Island Park, and around the Big Holes. The Snake Plain could see some light snow amounts as the 700mb trough arrives late tonight with a weak convergence event possible into early Sunday morning.
303 PM CDT Sat Oct 22 2022 18Z surface data has a strong low pressure near KABR. A cold front ran south and west from the low into northern Nebraska. Dew points were in the 50s from the Ohio Valley into the lower Mississippi Valley with 40s from the Great Lakes into the Plains.
Rising heights and surface ridging will ensure abundant sunshine again today, with afternoon highs several degrees higher than Fri and in the mid to upper 60s.
This will help keep overnight lows in the low to mid 60s overnight.
(This afternoon through Sunday night) An upper trough is digging southward over the western part of the country with westerly upper winds over West Texas and Southeast New Mexico. The upper trough will move further east on Sunday with surface winds increasing out of the south to southwest. Winds will likely reach high wind criteria across the Guadalupe and Delaware mountains as the base of the trough moves over the area so a High Wind Warning is in effect Sunday morning through Sunday afternoon for these areas. Temperatures are expected to cool off a bit on Sunday as lower heights move over the area from the approaching upper trough. Rain chances will increase Sunday night as upper lift from the trough moves over the area.
(Today through Sunday) As the last lingering piece of upper trough energy cuts off to the east and phases with some Atlantic moisture, the low should stay off the coast tracking north near the mid-Atlantic region by Sunday and allow for a continued dry ridge dominated regime for the CWA through this weekend. Temps look to continue to moderate warmer and highs today should make it to about a degree or so below climo with many locations in the low 70s. Lows tonight will still have some decent radiational cooling but will be warmer than past days and should stay in the 40s without any frost/freeze concerns.
346 PM EDT Sat Oct 22 2022 Low pressure off the coast will start to lift northeastward Sunday.
Dewpoints in the southwest are in the upper 50s, which is a welcomed change and we're seeing temperatures west of the Tennessee River already in the low 70s. (Today through Sunday) Early this Saturday morning, temps were much warmer than the past several mornings, with most locations in the 50s. Deep southwest flow and a building upper ridge will keep the warming trend going this weekend with highs mostly in the 70s and lows mostly in the 50s.
An upper level trough has dug into Northern California this morning. The axis, or coldest part of the trough, is expected to slide eastward over the Northern Rockies this afternoon. Later this evening, as flow turns northerly, this precipitation will be pushed south into southwest Montana by a weak cold front.
The clouds might win out and keep the highs today a little more subdued. Temperatures tonight through Sunday night will be several degrees warmer than normal and with RH values running just a little higher than they have been the last couple of weeks.
144 PM PDT Sat Oct 22 2022 Cooler temperatures and breezy conditions this weekend.
The tightening pressure gradient between this feature and a developing cyclone on the leeside of the Rockies will result in continued breezy conditions, with southerly wind gusts this afternoon and again during the daytime tomorrow up in the 25 to 30 mph range (especially for areas farther north and west). Similarly, highs on Sunday will be near or a few degrees warmer than today.
10" Sunday and Sunday night as moisture from Tropical Cyclone Roslyn moves into the area. Temperatures will be mild overnight tonight under clear skies but increasing cloud cover Sunday night will lead to slightly warmer low temperatures.
(This evening through Sunday) High pressure will continue developing over the southeast US today and slowly move east through Sunday.
Amplifying high pres, in response to wrn CONUS troughing, wl maintain dry, and seasonably cool weather tonight.
319 PM EDT Sat Oct 22 2022 Current surface analysis still has a 1025mb high off to our southeast and that will continue to provide mostly clear skies and warmer temperatures for today and tomorrow. However, as the more potent longwave trough situated over the Central Rockies ejects into the Plains, that weak maxima will be absorbed into the flow and track to the N/NE. Otherwise, Sunday will be very similar to today but with warmer temperatures due to a lack of plummeting overnight temperatures.
255 PM EDT Sat Oct 22 2022 High pressure remains in control along the East Coast today.
The cold front accompanying a Pacific storm system is making its way into eastern Idaho this morning. Tonight will be cold with freezing temperatures possible in the Snake Plain from Mountain Home eastward into the Magic Valley.
A modest axis of mid level northward moisture transport will fixate along an advancing elevated warm frontal zone Sunday night.
Mean layer ridging will persist to our west, with a semi-cutoff low to our east.
1238 PM CDT Sat Oct 22 2022 (Today through Sunday) Slight ridge building across the region while moving east.
203 PM MDT Sat Oct 22 2022 Potent upper trough is currently digging into the western CONUS with downstream pressure falls supporting cyclogenesis over WY. Sfc front struggling to mix back north as a warm front given thick cirrus and poor mechanical mixing. Forecast models have now supported a stronger northern stream counterpart to the splitting trough, with an uptick in forcing, jet dynamics over the region, and resultant QPF. Thermal fields become less supportive for heavy snow as one moves east into far western SD given warmer thermal fields, with the main area forcing below the DGZ.
The developing coastal low will remain east of the area with ridging dominating through the weekend. Sunday morning lows will remain below normal, though the moderating trend will keep temperatures sufficiently warm to preclude any freezing temperatures or frost concerns.
1212 PM CDT Sat Oct 22 2022 (Today and tonight) Above normal temperatures are expected again today across West Central Texas, as weak upper level ridging dominates the region.
H5 low pressure is currently analyzed roughly over Washington State, with deep troughing extending into Southern California. This is expected to slowly work eastward, with ensemble support for the development of a closed low by late this evening. The heaviest rain will occur as moisture wraps around the upper low, with the Devils Lake Basin looking to receive the highest amounts up to one inch.
Aloft, a cut off low pressure off to our east over the southwest Atlantic will continue to lift off to the north towards the South Carolina coastline through early this evening. Off to our west, weak ridging aloft begins to build into our region behind this feature. At the surface, high pressure continues to meander over the eastern CONUS through the period, with surface ridging extending into the region from the northeast putting us on the southwest periphery of this feature.
Very quiet and stable conditions over land areas will prevail as we are under the influence of the high pressure ridge. The daytime maximum temperatures are on track, as temperature observations are already into the lower 80s this afternoon.
On the backside of the trof Sunday night, light snow looks possible over NC SD as departing deformation zone grazes the region.
113 PM EDT Sat Oct 22 2022 The region remains between high pressure over the Mid Atlantic and low pressure moving from the Rockies toward the Upper Midwest into the start of the week.

1003 PM EDT Sat Oct 22 2022 The region remains between high pressure over the Mid Atlantic and low pressure moving from the Rockies toward the Upper Midwest into the start of the week.
655 PM CDT Sat Oct 22 2022 (This afternoon through Sunday night) An upper trough is digging southward over the western part of the country with westerly upper winds over West Texas and Southeast New Mexico. The upper trough will move further east on Sunday with surface winds increasing out of the south to southwest. Winds will likely reach high wind criteria across the Guadalupe and Delaware mountains as the base of the trough moves over the area so a High Wind Warning is in effect Sunday morning through Sunday afternoon for these areas. Temperatures are expected to cool off a bit on Sunday as lower heights move over the area from the approaching upper trough. Rain chances will increase Sunday night as upper lift from the trough moves over the area.
Reports of snow accumulating on road surfaces at the higher elevations have come in today with several inches on the rim road at Crater Lake, and sticking to the road surfaces down from there to highway 62. The upper trough will gradually move to the east tonight. Showers are forecast to taper off late Sunday morning and early Sunday afternoon as a weak upper ridge builds into the area. With the continued showers and cloud cover temperatures west of the Cascades low temperatures are expected to remain in the upper 30s and warmer and frost is not expected on the west side tonight into Sunday morning. East of the Cascades temperatures are expected to drop well below freezing with road temperatures continuing to drop from the 60s and higher from yesterday, to possibly seeing some spots of freezing road surfaces by Sunday morning.
859 PM CDT Sat Oct 22 2022 00Z upper air analysis places an upper level low off the Northeast Florida coast, an upper level low in the Pacific Ocean near Southern California and zonal to southwest flow aloft over the Southern Plains and Lower Mississippi Valley. Meanwhile, at the surface southerly winds on the back side of high pressure are present across the region.
The ridges will continue to see breezy conditions.
High pressure will hold over the region with mostly clear skies overnight and tomorrow. and around 60 to the lower 60s central and south. Highs on Sunday will be in the lower to mid 80s across all of west central and southwest Florida. Very quiet and stable conditions over land areas will prevail as we are under the influence of the high pressure ridge. The daytime maximum temperatures are on track, as temperature observations are already into the lower 80s this afternoon.
Even warmer yet tomorrow -- maybe a few spots in the low 80s -- but we're still a few days away from getting some rain in here. The clouds might win out and keep the highs today a little more subdued. Temperatures tonight through Sunday night will be several degrees warmer than normal and with RH values running just a little higher than they have been the last couple of weeks.
851 PM EDT Sat Oct 22 2022 High pressure remains in control along the East Coast this evening.

Thermal fields become less supportive for heavy snow as one moves east into far western SD given warmer thermal fields, with the main area forcing below the DGZ.
A coastal low pressure system will bring a chance for light rain showers Sunday night across areas east of Interstate 81.
740 PM EDT Sat Oct 22 2022 The region remains between high pressure over the Mid Atlantic and low pressure moving from the Rockies toward the Upper Midwest into the start of the week.
723 PM EDT Sat Oct 22 2022 Low pressure off the coast will start to lift northeastward Sunday.
(Tonight) Upper level ridging will slowly build over the eastern CONUS for the later half of the weekend, and thus have seen an increase in tropical moisture across areas just to our west. The southerly fetch will keep warmer conditions in place overnight compared to a few nights previous, with lows only dropping to the low 50s and upper 40s.
A few other features visible are a low pressure off of the Carolina coast and the associated parent longwave trough extending down eastern Cuba.
926 PM EDT Sat Oct 22 2022 Low pressure off the coast will start to lift northeastward Sunday.
Lows will vary based on clouds and where calm/clear skies persist some locations may drop to the lower 30s (currently mid 30s favored for clear areas based on NBM). H5 low pressure is currently analyzed roughly over Washington State, with deep troughing extending into Southern California. This is expected to slowly work eastward, with ensemble support for the development of a closed low by late this evening. The heaviest rain will occur as moisture wraps around the upper low, with the Devils Lake Basin looking to receive the highest amounts up to one inch.
