Aikyam-Lab/Synoptic-Bench huggingface dataset:
1001 PM MDT Thu Oct 27 2022 Overview: A robust upper level low -- centered in north-central NM (per 20Z WV imagery and SPC Mesoanalysis data) -- will dig SSE into west TX late tonight. then meander /nearly stall/ over portions of the lower- central MS River Valley (Sat-Sat night). Through Tonight: Light precipitation over northwest KS (mainly east of Highway 83) -- associated with diffluent flow aloft and/or cyclonic shear vorticity on the northern periphery of a ~100 knot jet streak in Oklahoma -- will wane/dissipate late this afternoon and evening (00-06Z) as the aforementioned upper low progresses SSE from NM into west TX. While additional precipitation /convection/ directly associated with the upper low will rapidly develop this evening.
113 AM EDT Fri Oct 28 2022 High pressure will maintain dry weather through the weekend, with a a gradual warming trend. High pressure across the Ottawa Valley will slide into northern New England into Friday and maintain fair weather across the region. This will result in favorable radiational cooling conditions tonight, with temperatures falling to near or below freezing for most areas. It will remain locally warmer near the immediate lakeshores though. Patchy valley fog may develop overnight, but expect coverage to be limited due to the dry air mass and below freezing temperatures. Friday will be warmer with highs in the 50s and light winds less than 10 mph.
High pressure builds back into the region heading into the weekend, resulting in slightly warmer and dry conditions. Quiet night tonight as an upper low moves away from the state and a s/wv ridge moves in from the west. Expect a cool night tonight and and slightly warmer day tomorrow.
Mean layer ridging centered over Central America reaches northeast across Florida. Water vapor imagery highlights a potent mid- latitude cyclone near Texas, and a lengthy trough axis from Bermuda to the Greater Antilles. High pressure centered to the northeast of the Great Lakes covers the eastern half of the CONUS. Mean layer ridging will hold off mid-latitude assaults from the north, with the Pacific short wave energy spreading east and northeast across the CONUS.
118 AM MDT Fri Oct 28 2022 Current WV imagery and upper level analysis depicts a ridge building over the western CONUS, with a low down in Texas, and a trough beginning to dig over the Gulf of Alaska. At the surface, a trof extends through eastern Montana and central Wyoming. A split flow pattern will continue to develop at the upper levels as the low down in Texas splits from the northern flow, allowing the western ridge to collapse and the low in the Gulf of Alaska to deepen.
This marks a shift in the pattern with a longwave trough stretching from Canada into Mexico by week's end, yielding perhaps the next precip chances for the U. Lows will be responding accordingly, of course, with 30s (mostly above the freezing mark) and 40s prevailing.
222 AM EDT Fri Oct 28 2022 High pressure centered over lower Ontario/Quebec into upstate New York will drift to the east over the next several days, bringing a string of pleasant mid autumn days.
The ridge axis is building back in as another trough axis propagates eastward. This trough axis is already positively tilted and becoming vertically stacked. The trough is weakening and - as such - should be enveloped by the stronger background flow and broader longwave features. With the upper-level trough retracting northward and - despite amplification in the pattern across the CONUS - ridging stays in place.
329 AM EDT Fri Oct 28 2022 High pressure will maintain dry weather into the weekend.
112 AM MDT Fri Oct 28 2022 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.
209 AM CDT Fri Oct 28 2022 Non zero precipitation probabilities will linger along the KS/OK line early this morning as the large upper low digs into west Texas this morning, reaching east Texas late Tonight. The upper low moving across Texas will still spread a few spokes of mid level omega, keeping a lot of cloud cover across the southeast sections over the afternoon, limiting highs to the 60s. Sky ought to be completely clear by this evening, and with this clearing, the light winds overnight should aid temperatures to fall into the low 30s especially over the western sections of the area.
The net result will be a thick blanket of low cloud cover which will remain in place through much of the day today with high temperatures consequently expected to remain stuck in the low 50s. Areal precip coverage is expected to be scattered to widespread especially along and east of the edge of the Caprock, however given the current and projected speed of the upper low, there may end up being a fairly sharp cutoff in precip coverage west of Hwy-385. Precipitation will quickly end from west to east by late afternoon as the upper low departs eastward and subsidence spreads overhead. Winds overnight will become fairly light as surface ridging rebuilds over the region, and this combined with clearing skies will result in a chilly night as temperatures fall into the 30s/40s.
The overall pattern remains in flux with another digging trough and deepening upper low now over the Four Corners region. An upstream ridge is over the Pacific northwest into the Intermountain West behind this upper low.
1218 AM MDT Fri Oct 28 2022 The High Wind Warning for the Rocky Mountain Front and adjoining plains zones was either cancelled early or allowed to expire at midnight (eastern Glacier/western Toole counties) as winds have diminished and bufkit forecast soundings indicate that wind gusts will remain below the 75/60 mph threshold.
Ridging today will transition to zonal flow Friday into the weekend. Slightly cooler than average weather this afternoon gives way to near normal conditions Friday, which translates to highs in the upper 40s to mid 50s.
139 AM EDT Fri Oct 28 2022 Drier and slightly cooler airmass will give way to more cloudiness across the area today and through the weekend. Surface front well offshore with weak area of low pressure along its boundary.
High temperatures Friday will range from the low to mid 60s (for areas under wedge influence) to mid 70s further south. Deterministic guidance indicates the wedge will continue to strengthen and stick around through much of the weekend at which point it begins to break down in response to an approaching closed upper low to our west.
Elsewhere, dry and benign weather has prevailed overnight and this trend will continue through the remainder of the day as a transitory ridge of high pressure slides overhead.
This should lead to very minimal rainfall accumulations, with the highest chance of measurable rain in Osage or Pawnee Counties over the next 1-2 hours. Overnight, a low end risk of showers will continue with the highest PoPs gradually shifting towards SE Oklahoma.
328 AM 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.
A strong upper low moving out of New Mexico into western Texas provided enough forcing to produce some light rain showers across the area late Thursday night.
Looking at water vapor imagery this morning, the main feature is a nearly cutoff upper trough moving southeast over western Texas. Across our area, moisture streaming northeast ahead of the mean trough axis had helped develop a band of light rain yesterday evening. These should be gone by sunrise as the upper low moves farther southward away from us and isentropic ascent continues to drop off. Skies will clear by afternoon as surface ridging moves in from the north.
303 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.
Some mid/high clouds persist this morning as a mid-level trough swings across 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).
In addition, ripples of gravity waves have formed downwind several ranges; an indication of stable conditions in the wake of the trough with waves oscillating above cold valley pools. Friday morning will be some of the coldest temperatures felt yet this Fall, with lows dipping into the mid twenties across desert floors and single digits to low teens for the high valleys and mountain towns. A ridge of high pressure builds overhead Friday, allowing for temperatures to rise under modest warm air advection. Despite a frigid morning temperatures are forecast to climb 5 to 10 degrees warmer tomorrow. Dry and tranquil weather continues into Friday night, while under the influence of the ridge.
1229 AM CDT Fri Oct 28 2022 (Rest of tonight) Tranquil weather across the Tennessee Valley this evening, with high pressure at the surface making for mostly clear and calm conditions. The one caveat will be the high cirrus clouds currently streaming into the area from convection well to the southeast across the ArkLaTex.
As a ball of low pressure stirs the pot well to our south, upper level zonal flow dominates in our neck of the woods.
252 AM CDT Fri Oct 28 2022 06Z surface data has high pressure over the Great Lakes with a storm system over Texas.
1211 AM EDT Fri Oct 28 2022 High pressure should maintain dry weather into the weekend.
Upper level geopotential height rises continue to evolve as an H500 ridge builds in from the SSW. By tomorrow, amplified upper level ridging will continue to build over the FL peninsula. This will result in a tightened geopotential height/pressure gradient as the upper ridge approaches an occluded cyclone over the Atlantic waters. Enhanced NE 1000-850 hPa winds around 10-15kt should develop, allowing for breezy and cooler/drier conditions near the immediate Atlantic coast. Maximum temperatures in the mid/upper 80s are expected across South Florida this afternoon, while tomorrow may be slightly cooler along the immediate Atlantic coast.
1153 PM MDT Thu Oct 27 2022 The closed upper low continues to dive into central New Mexico this evening with a drying and subsident airmass taking over across Northern Colorado. Upper level low that brought the rain and snow to the region will track southeast across the Southern Rockies tonight and across Texas Friday. Upper level ridging builds over Colorado for Friday. Sunny skies and mild temperatures will prevail under the ridge. Friday night, a deep closed upper low will be moving across Northeastern Texas with an upper level ridge of high pressure over Colorado. Over the weekend, a weak upper trough will move across the area with seasonable temperatures expected. Despite the passage of the trough, no precipitation is expected due to a lack of moisture.
Extensive cirrus on satellite imagery will help keep temperatures warmer tonight versus last night, despite the lower dewpoints and lighter winds. (This afternoon through Friday Night) Sprawling high pressure covered most of the eastern U. Fair wx will continue tonight through Friday with seasonable lows tonight and warmer highs for tomorrow. The next significant wx system coming our way is a low pressure over the Four Corners. The low will move out to Texas by Friday evening.
However this atmospheric river and cold front that accompanies it weakens as it slowly sags to the south. Snow levels will be quite high, above the high mountain passes, mainly around Crater Lake and above.
An upper-level ridge will quickly build in Friday, ushering in the return of positive 700 mb temperatures.
644 AM EDT Fri Oct 28 2022 High pressure will extend across the area into Saturday night.
With upper level ridge pushing across the area and strong mixing of blyr warmth on southwesterly SFC winds today highs will climb into the upper 50s and low to mid 60s. A bit cooler as a weak cool front moves across the area Saturday morning with 60s expected only in the far southern valley and west central MN and upper 50s elsewhere with more clouds expected Saturday compared to today. The trend for this period is generally for warmer temperatures and continued dry conditions.
A deep trough will dig into the southwest before lifting out across the central Plains.
640 AM EDT Fri Oct 28 2022 High pressure will build southward into New England today and persist through this weekend, bringing a return to more seasonable temperatures and dry weather conditions.
06Z surface data has high pressure over the Great Lakes with a storm system over Texas.
High pressure ridging will remain early this morning. This high pressure will bring clear skies and light winds. Thus, patchy freezing fog is possible this morning. By this afternoon a weak trough will break down the ridge bringing more zonal flow aloft later today into Saturday.
543 AM CDT Fri Oct 28 2022 (Today) Upper low will track across central Texas during the day today bringing some rain chances to the area, mostly south of 40. Off and on showers can be expected to increase in coverage somewhat across southeast OK heading into the afternoon as the upper low approaches. Temperatures will be cooler across the south and warmer across the north this afternoon, due to the thicker cloud cover and rain.
613 AM 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.
Quiet weather will persist through tonight as strong high pressure centered over Ontario this morning drifts slowly east into New England by Saturday. southwest flow dominated across much of the eastern U S ahead of an upper low diving into west Texas. gradually promoting an amplifying downstream ridge across the Ohio Valley. With surface ridging extending back across the lower Great Lakes and Ohio Valley. High clouds will continue to drift across the region as upper level moisture is pulled northeast from a surface wave tracking across Texas in tandem with the aforementioned upper low. These clouds will maintain a periodic milky look to the sky with filtered sunshine through the first half of the day but as the ridge aloft flexes later today. Low level thermals support highs warming into the lower and middle 60s.
Meanwhile, mid level ridging over the area will strengthen and keeps overall subsidence in place during the short term. At the surface, high pressure over the west Atlantic will increase pressure gradients against the stalled front, with winds across the Atlantic waters and coast increasing this afternoon. Thus, expect period of cooler breezes along SoFloâs east coast. Expect afternoon high temperatures to be in the mid to upper 80s, warmer over the western interior sections and slightly cooler along the east coast.
1030 AM 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).
841 AM EDT Fri Oct 28 2022 High pressure will extend across the area into Saturday night.
As the trough and upper low move eastward, areas in the the northwest quadrant will have less thunder than areas to the east.
632 AM 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.
Non zero precipitation probabilities will linger along the KS/OK line early this morning as the large upper low digs into west Texas this morning, reaching east Texas late Tonight. The upper low moving across Texas will still spread a few spokes of mid level omega, keeping a lot of cloud cover across the southeast sections over the afternoon, limiting highs to the 60s. Sky ought to be completely clear by this evening, and with this clearing, the light winds overnight should aid temperatures to fall into the low 30s especially over the western sections of the area.
Afternoon high temperatures will range from the lower 80s for far northern counties to the upper 80s further south.
(Today through Saturday afternoon) An upper level low/trough is centered over the Permian Basin. This upper low/trough will become centered over Central Texas by this evening and will lift northeastward over Arkansas by Saturday evening. Temperatures today will be much cooler behind the cold front with highs only expected to be in the 50s and 60s across most of the area.
747 AM EDT Fri Oct 28 2022 High pressure will maintain dry weather into the weekend.
710 AM EDT Fri Oct 28 2022 (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.

943 AM EDT Fri Oct 28 2022 High pressure will build southward into New England today and persist through this weekend, bringing a return to more seasonable temperatures and dry weather conditions.
and Saturday Through Saturday, Wisconsin will reside on the western periphery of a large high pressure system that spans the Great Lakes and far northeast United States. South winds will gradually bring a warmer air mass into the region, with temperatures rising well above normal. Based on yesterdays highs, it appears that the warmer guidance sets will verify better over the next few days. Highs should be in the middle 50s to around 60 range today, and upper 50s and lower 60s on Saturday, with slightly cooler readings lakeside.
640 AM EDT Fri Oct 28 2022 High pressure centered over lower Ontario/Quebec into upstate New York will drift to the east over the next several days, bringing a string of pleasant mid autumn days.

1131 AM MDT Fri Oct 28 2022 Relatively quiet and warmer conditions expected this forecast period. The upper low which moved across the area yesterday will continue southeast today as upper ridging occurs and as much drier air filters in.
(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.
With the aformentioned short-lived ridge overhead today, light winds, full sun, and slightly warmer temperatures are well in place across the entire forecast area.
A few exceptions will be high temperatures in smaller valleys where weak cold pools have developed, highs in the lower 40s will be present Friday and Saturday.
1227 PM CDT Fri Oct 28 2022 (Today through Saturday afternoon) An upper level low/trough is centered over the Permian Basin. This upper low/trough will become centered over Central Texas by this evening and will lift northeastward over Arkansas by Saturday evening. Temperatures today will be much cooler behind the cold front with highs only expected to be in the 50s and 60s across most of the area.
Readings are ranging from the low 30s where skies have been able to clear to around 50 degrees closer to the lakefront and where high clouds are more plentiful. Sprawling high pressure centered over southern Quebec will dominate our weather regime through Saturday. Lows in the lower 30s are expected, a few degrees warmer along the lake front. Saturday will yet again be a few degrees warmer than today under a partly cloudy sky.
Models show the upper ridge now in place to transition into weak upper troughing through the day Saturday. The low level winds should adhere to normal diurnal patters.
232 PM EDT Fri Oct 28 2022 Dry and tranquil weather conditions will persist through the weekend with a strong high pressure system overhead.
