Aikyam-Lab/Synoptic-Bench huggingface dataset:
247 PM MDT Fri Oct 28 2022 Overview: A robust upper level low -- centered invof Abilene, TX (per 19Z WV imagery and SPC Mesoanalysis data) -- will track east toward Ark-La-Tex (tonight). meander /nearly stall/ over the lower MS River Valley (Sat-Sat night). Through Saturday: Expect clear skies and a warming trend -- assoc/w synoptic subsidence on the western periphery of the slow- moving upper low invof the lower-central MS River Valley.
High pressure over the western Atlantic continues to strengthen as well, providing subsidence along with an abundance of dry air aloft primarily above 850mb. The ridging of high pressure looks to strengthen today and tomorrow, resulting in breezy ENE winds today and could become slightly more breezy tomorrow. Temperature-wise, the interior and west coast areas will be warmest in the short term likely in the mid to upper 80s with the east coast a little cooler. Overnight lows will be in the upper 60s to near 70 for most areas while the east coast should be slightly warmer in the low 70s.
These showers should continue to wane and dissipate by early afternoon as the main precip moves to the southeast with the upper level low. With the higher moisture and clearing skies, the chance of seeing patchy fog around the area is increasing with the southwest TX Panhandle most favored.
Early afternoon water vapor imagery/RAP analysis showed the circulation around a closed upper level low spinning over central Texas.
220 PM EDT Fri Oct 28 2022 High pressure centered near Montreal this midday hour will drift to the east over the next several days, bringing a string of pleasant mid autumn days.
131 PM EDT Fri Oct 28 2022 Dry and tranquil weather conditions will persist through the weekend with a strong high pressure system overhead.
At the surface, high pressure was centered near Montreal with ridging extending back across northern lower Michigan. Strong ridging and associated subsidence will keep us dry.
1145 AM EDT Fri Oct 28 2022 High pressure centered near Montreal this midday hour will drift to the east over the next several days, bringing a string of pleasant mid autumn days.
(Tonight through Saturday night) The cold front has moved offshore, resulting in drier air and the cessation of precipitation over the CWA. A strong upper level low pressure system is predicted to move slowly across the Texas tonight through Saturday morning, then lift northeastward toward the Mississippi Valley Saturday afternoon/Saturday night. Cooler temperatures are expected with lows tonight/Saturday night in the 50s, similar to the NBM and HREF/SREF ensemble mean temperature.
Moisture advection ahead of this approaching closed low will result in increasing cloud cover across the western portion of our area this evening and into tonight, helping to keep low temperatures warmer compared to last night. The aforementioned closed low over north central TX will gradually lift NE throughout the day on Saturday, eventually centering itself over northern AR by late day.
(This evening through Saturday) An upper low over the region will brings a scattered light showers, mainly over the Big Country this evening. Clearing conditions are expected from west to east late tonight into early Saturday morning, as the upper low moves into Northcentral Texas. Gusty north winds behind the cold front will subside late evening.
326 PM EDT Fri Oct 28 2022 Dry and tranquil weather conditions will persist through the weekend with a strong high pressure system overhead.
122 PM EDT Fri Oct 28 2022 Nice day today with high pressure and southwest flow aloft bringing some high clouds to the region. (Today and tonight) Key Message: Dry conditions persist along with above normal temperatures Discussion: The closed low over West Texas and associated trough over the southern Plains has produced southwesterly flow aloft over the forecast area. Southerly winds in the low levels will aid in bringing warmer and slightly more moisture back to the region(in the form of humidity rather than precipitation).
1217 PM CDT Fri Oct 28 2022 (Today through Saturday) Dewpoints and temperatures will be a few degrees higher than what we saw yesterday thanks to this weekend's approaching low pressure system.
The closed low to our south is forecast to begin lifting northeastward this evening, which will allow for the precipitation shield to shift back a bit further to the north for a time, perhaps as far north and west as the OKC metro. A few showers may stick around into Saturday morning for central/eastern sections with models now trending more pessimistic regarding how quickly things will clear out on the backside of the low. It still appears northern Oklahoma will clear out by Saturday afternoon with highs in the low to mid 60s there.
415 PM EDT Fri Oct 28 2022 High pressure will build across the region through the weekend.
1212 PM CDT Fri Oct 28 2022 A mid/upper trough over the Southern High Plains early this morning is progged to move eastward over the northern Texas today. This southern storm track should result in most of the precipitation remaining south of our area with increasing large-scale forcing for subsidence developing on the northern periphery of the mid upper trough as we move through the day.
240 PM CDT Fri Oct 28 2022 (Issued 240 PM CDT Fri Oct 28 2022) Tonight through Saturday night: The high cirrus will clear as the upper level short wave moves east. We'll remain under an axis of high pressure continuing light southerly winds with almost calm winds overnight.
(This afternoon through Saturday night) Latest visible satellite imagery shows the eastern half of our area under low clouds as the backside of an upper level low slowly slides to the east. Light showers will gradually move to the east with the low and drier air will continue to filter across the region.
This will help keep temperatures on the warmer side overnight as lows only reach down into the mid to upper 30s.
This feature will continue to send some mainly high clouds toward the Lower Ohio Valley. Given this expect mostly clear and calm conditions tonight, with decent ridge/valley temperature splits, as temperatures drop into the mid to upper 30 in the valleys and low to mid 40s on the ridges. Saturday, this previously mentioned upper level low will move into the Middle Mississippi River Valley. This low will become more of an open wave, as it phases more with the northern stream.
317 PM EDT Fri Oct 28 2022 Western periphery of a strong 1035 mb high pressure system will maintain dry weather today under mostly sunny skies. Temperatures will push into the lower 60s given full solar insolation, barring any late dissipation of dense fog development.
Otherwise, weather will be quiet today underneath flat ridging and above normal heights. JKL Weak ridging this morning will break down this afternoon as a disturbance and jet energy push east across the northern Rockies and southern Canada. These features will drag a weak Pacific cold front through the region at the surface which will bring an end to the strong wind potential over the western foothills later this morning.
1255 PM EDT Fri Oct 28 2022 Dry and tranquil weather conditions will persist through the weekend with a strong high pressure system overhead.
254 PM CDT Fri Oct 28 2022 Eastern Iowa, northwest Illinois, and far northeast Missouri sit on the western edge of high pressure that is centered over northern New England.
129 PM EDT Fri Oct 28 2022 Aviation --Fog Possible Next Few Mornings-- High pressure will dominate the pattern through Saturday. With high pressure continuing to dominate tonight into Saturday, patchy fog will be possible again.
A few exceptions will be slightly cooler high temperatures in a few smaller valleys Saturday.
Today and Tomorrow: A compact trough stands out this afternoon in mid-level water vapor imagery over Texas/Oklahoma/Louisiana and generally zonal flow north of the system. Highs are going to shortly top out in the low-to-mid 60s area-wide while south to southwesterly winds continue at leisurely speeds.
For tonight, as the slightly cooler/drier air filters into the CWA, look for overcast skies to linger (especially across our northern counties) with some patchy areas of light rain/drizzle as the mid/ upper low lags the initial surface wind shift. Light NW winds will help to drop overnight lows into the mid and upper 50s tonight but lows should be a bit cooler tomorrow night given the clearer skies and lighter winds. Low tomorrow night should range from the lower 50s north to the mid and upper 50s south and coast. Skies expected to clear late tomorrow morning from the SW to NE as the low press- ure system moves out. Highs tomorrow will range from mid and upper 60s north to the lower 70s for the central, south and coast.
1017 AM CDT Fri Oct 28 2022 Skies are partly cloudy across the Mid-South this morning with temperatures in the lower 50s to mid 60s.
An upper low across central TX continues to produce rain showers across north TX and southern OK. As the upper low slowly progresses northeastward tonight into Saturday, a few showers cannot be ruled out for far southeast KS.
Transient high pressure is providing dry, slightly warmer conditions this afternoon.
204 PM MDT Fri Oct 28 2022 Fairly tight downslope gradients remain in place, and area-wide pressures continue to fall in advance of a weak cold front which is over western MT. Winds are gusting 30-40 mph along our western foothills, and gusts have reached the 30s along the Clarks Fork valley from Bridger to Laurel & Billings.
210 PM EDT Fri Oct 28 2022 Dry and tranquil weather conditions will persist through the weekend with a strong high pressure system overhead.
1212 PM CDT Fri Oct 28 2022 An expansive area of high pressure centered over New England will continue to keep central Illinois dry through Saturday afternoon.
Ahead of this system, upper-level ridging continues to amplify across the Appalachians with warming temperatures across the region.
1121 AM EDT Fri Oct 28 2022 High pressure will maintain dry weather through the weekend, with a a gradual warming trend. High pressure will slide into northern New England today and maintain fair weather across the region.
(Tonight) Areas of light to moderate to rain will begin to spread into southeast Oklahoma this evening and into west-central Arkansas late tonight as upper low shifts into far northeast Texas. (Saturday through Friday) Areas of mainly light rain will persist across southeast Oklahoma and northwest Arkansas on Saturday as upper low lifts into western Arkansas. With the expected cloud cover/precip, lowered high temperatures compared to the warmer NBM guidance, especially across northwest Arkansas. Rain will begin to taper off across far northwest Arkansas Saturday night as upper low lifts into the mid Mississippi River valley.
1253 PM CDT Fri Oct 28 2022 Skies are partly cloudy across the Mid-South this morning with temperatures in the lower 50s to mid 60s.
151 PM MDT Fri Oct 28 2022 Current WV imagery and upper level analysis depicts split flow pattern with a closed upper low over TX/OK and more zonal flow to the north with weak ridging over the Northern Plains. Southerly winds at the sfc and subsidence are bringing about warmer temperatures and clear skies this afternoon. Temperatures are currently in the low to mid 60s.
723 PM EDT Fri Oct 28 2022 High pressure centered near Montreal will drift to the east over the next several days, continuing our string of pleasantly mild and dry mid-autumn days.
This evening, temperatures were near 80 with dewpoints in the lower 70s. East winds were 10 mph or less across much of the lower Keys, but a more northeasterly wind surge had begun across the middle upper Keys, with speeds near 17-18 knots along the reef. Aloft, a 500 mb ridge axis aligned southwest-to-northeast with heights near 590 Dm overhead the Keys will hold in place. 0 mb gradient from JAX to KEY, and as the insolation-created troughing fills off the southwest Florida Keys, the increase in northeasterly winds should spread down the remainder of the Keys over the next couple hours. The moderate to occasionally fresh northeast winds along the Upper Keys are expected to spread through the Lower Keys later this evening.
Discussion: Subsidence behind an upper low tracking eastward across the southern plains will continue to maintain dry conditions across the region through tonight. Moderation of this air mass will take place on Saturday, as modest quasi-zonal midlevel flow becomes established across the central Rockies, favoring weak lee troughing across the eastern Colorado plains.
Extensive high clouds over our CWA are followed by a weak cold front extending from nw Montana to the Oregon coast and into the Pacific. The weak cold front will cool the upper levels but will barely be felt at the surface.
603 PM CDT Fri Oct 28 2022 (This evening through Saturday) An upper low over the region will brings a scattered light showers, mainly over the Big Country this evening. Clearing conditions are expected from west to east late tonight into early Saturday morning, as the upper low moves into Northcentral Texas. Gusty north winds behind the cold front will subside late evening.
Although the lower atmosphere still remains quite dry north of about Interstate 40, short term CAM guidance suggests enough activity to lead to a few hundredths of an inch through this evening (highest amounts further south). (Saturday through Friday) Areas of mainly light rain will persist across southeast Oklahoma and northwest Arkansas on Saturday as upper low lifts into western Arkansas. With the expected cloud cover/precip, lowered high temperatures compared to the warmer NBM guidance, especially across northwest Arkansas. Rain will begin to taper off across far northwest Arkansas Saturday night as upper low lifts into the mid Mississippi River valley.
939 PM EDT Fri Oct 28 2022 High pressure will build across the region through the weekend.
629 PM CDT Fri Oct 28 2022 (This afternoon through Saturday night) Latest visible satellite imagery shows the eastern half of our area under low clouds as the backside of an upper level low slowly slides to the east. Light showers will gradually move to the east with the low and drier air will continue to filter across the region.
1034 PM EDT Fri Oct 28 2022 High pressure centered near Montreal will drift to the east over the next several days, continuing our string of pleasantly mild and dry mid-autumn days.
758 PM EDT Fri Oct 28 2022 High pressure centered near Montreal will drift to the east over the next several days, continuing our string of pleasantly mild and dry mid-autumn days.
614 PM CDT Fri Oct 28 2022 (This evening through Saturday) Rain was ending from NW-SE across the region with the slow departure of a stacked upper cyclone currently over the Concho Valley. Would expect the lingering deformation zone precip to finally wind down across our SE zones a little after sunset with stratus clearing the most aggressively on the Caprock, and likely hanging up somewhere near the Highway 83 corridor. Blustery north winds this afternoon will taper this evening as surface ridging builds south, yet these winds are still shaping up a bit too elevated for fog formation. Modest ridging unfolds on Saturday as the upper low drifts from North Texas to the Ozarks.
Eastern Iowa, northwest Illinois, and far northeast Missouri sit on the western edge of high pressure that is centered over northern New England.
Latest GOES East Water Vapor Satellite Imagery shows a compact upper low pressure system over north central Texas with broad cyclonic flow over much of the forecast area.

924 PM EDT Fri Oct 28 2022 High pressure will allow for dry conditions through Saturday night.
623 PM CDT Fri Oct 28 2022 (Tonight through Saturday night) The cold front has moved offshore, resulting in drier air and the cessation of precipitation over the CWA. A strong upper level low pressure system is predicted to move slowly across the Texas tonight through Saturday morning, then lift northeastward toward the Mississippi Valley Saturday afternoon/Saturday night. Cooler temperatures are expected with lows tonight/Saturday night in the 50s, similar to the NBM and HREF/SREF ensemble mean temperature.
607 PM EDT Fri Oct 28 2022 High pressure will build across the region through the weekend.
Overview: A robust upper level low -- centered invof Abilene, TX (per 19Z WV imagery and SPC Mesoanalysis data) -- will track east toward Ark-La-Tex (tonight). meander /nearly stall/ over the lower MS River Valley (Sat-Sat night). Through Saturday: Expect clear skies and a warming trend -- assoc/w synoptic subsidence on the western periphery of the slow- moving upper low invof the lower-central MS River Valley.
723 PM EDT Fri Oct 28 2022 Clear skies and light easterly winds for the overnight period as high pressure governs conditions. Western periphery of a strong 1035 mb high pressure system will maintain dry weather today under mostly sunny skies. Temperatures will push into the lower 60s given full solar insolation, barring any late dissipation of dense fog development.
650 PM CDT Fri Oct 28 2022 (Tonight) Areas of light to moderate to rain will begin to spread into southeast Oklahoma this evening and into west-central Arkansas late tonight as upper low shifts into far northeast Texas. (Saturday through Friday) Areas of mainly light rain will persist across southeast Oklahoma and northwest Arkansas on Saturday as upper low lifts into western Arkansas.

Water vapor imagery highlights a mid-latitude cyclone near the Arklatex, with a squall line jettisoned to its southeast into the Gulf of Mexico.
301 AM EDT Sat Oct 29 2022 High pressure will remain over New England through the rest of this weekend, bringing more seasonable temperatures and dry weather conditions.
The increase in sky cover overnight may result in slightly more mild overnight lows in the low 40s by Sunday morning.
340 AM EDT Sat Oct 29 2022 Dry and tranquil weather conditions will continue through the weekend with a high pressure system overhead.
(Today) A very slow moving upper low will continue to lift northeast across the ArkLaTex Region today. Persistent light showers with some embedded moderate or heavy showers will stay focused close to the center of the upper low, mainly across southeast Oklahoma and into west central Arkansas, during the day today. So, only widely scattered light showers are expected across most of northeast Oklahoma as the low tracks northward. Occasionally gusty northerly winds will make it feel even cooler, especially with a lack of sunshine.
105 AM EDT Sat Oct 29 2022 Dry and tranquil weather conditions will continue through the weekend with a strong high pressure system overhead.
(This evening through Saturday) An upper low over the region will brings a scattered light showers, mainly over the Big Country this evening. Clearing conditions are expected from west to east late tonight into early Saturday morning, as the upper low moves into North Central Texas. Gusty north winds behind the cold front will subside late evening.
1109 PM EDT Fri Oct 28 2022 High pressure centered near Montreal will drift to the east over the next several days, continuing our string of pleasantly mild and dry mid-autumn days. The lower clouds along the MD border have shrunk back into the Virginias for the most part. Expect another morning of fairly widespread frost with mins around sunrise in the low to mid 30s.
Expect the weekend weather to be fairly uneventful as a weak upper level trough moves through the longer wave ridge that is currently over the southwest. A deep low is forecast to develop over the Pacific Northwest, diving south and pushing a strong cold front through the southwest. The latest NBM forecast precipitation amounts are near the high end of the ensemble distribution's range of possibilities. The greatest uncertainty in the forecast is timing of the trough/cold front.
(Today through Sunday) A closed upper low is moving across the Arklatex region this morning. The limited instability will probably keep actual rainfall amounts on the lighter side of what we could see, but the path of the upper low will keep the deeper moisture and showers over us for a prolonged period of time. (Sunday Night through next Saturday) By Sunday night the closed low will open up into a broad wave and slowly push east.
An U/L subtropical ridge will build over Florida through mid week. High pressure will hold over the waters through the period with a relatively weak gradient which will create rather benign conditions with winds less than 15 knots and seas less than 3 feet through the period.
1251 AM CDT Sat Oct 29 2022 (This evening through Saturday) An upper low over the region will brings a scattered light showers, mainly over the Big Country this evening. Clearing conditions are expected from west to east late tonight into early Saturday morning, as the upper low moves into North Central Texas. Gusty north winds behind the cold front will subside late evening.
1246 AM EDT Sat Oct 29 2022 Dry and tranquil weather conditions will continue through the weekend with a strong high pressure system overhead.
850mb temperatures will be slightly cooler than yesterday, but still allow for above normal surface temperatures. Forecast highs range from the upper 50s to the lower 60s.
and Sunday Through Sunday, Wisconsin will reside on the western periphery of a large high pressure ridge that extends from the Great Lakes through the northeast United States. Light southerly winds will continue to pull warmer air into the region, leading to much above normal temperatures. Under mostly sunny skies, temperatures should rise into the lower to middle 60s, expect middle to upper 50s near lake Michigan. Low pressure over the Central Plains will drift north into MO/IL on Sunday, with associated mid/high clouds spreading into GRB CWA during the day.
