Aikyam-Lab/Synoptic-Bench huggingface dataset:
In general, the next several days will be characterized by highs in the low to mid 70s, overnight lows in the 40s inland and 50s along the coast, and winds at or below 10 knots.
A dry cold front will move through tonight with the only noticable feature is a shift in winds. Overnight lows will range from the middle 30s for the Plateau to near 40 in the warmer heat island of Nashville. Highs tomorrow will be a bit cooler than today /remember cold front passage/ with near 40 for the Upper Cumberland Plateau to middle to upper 50s across the south near the Alabama state line. A dry cold front will move through the terminals after 09z tonight and winds will veer to the northwest and increase to around 10 kts.
603 PM CST Mon Nov 16 2020 Skies will be mostly clear tonight with the winds shifting from the southwest to the northwest overnight as a cold front moves through the region. High temperatures will be cooler on Tuesday, in the 40s.
645 PM EST Mon Nov 16 2020 A dry cold front will move through the area on Tuesday, bringing substantially cooler and windy conditions.
238 PM MST Mon Nov 16 2020 Very few clouds are visible across the CWA this afternoon, thanks to a ridge of high pressure and dry airmass building overhead. Tonight, a deepening low pressure system spinning along the Pacific Northwest will help amplify and shift the ridge eastward, pushing the high directly overhead.
/issued 253 PM CST Mon Nov 16 2020/ Skies remain sunny across the Mid-South this afternoon with temperatures in the low to mid 60s. High pressure will remain over the southern U. Temperatures will be cooler than normal tonight with lows Tuesday morning from the mid 30s to lower 40s. A cold front will drop south into the region on Tuesday. Temperatures will be a few degrees cooler on Tuesday with highs in the mid 50s to mid 60s. High pressure will build back into the region by Tuesday night with continued dry weather.
748 PM EST Mon Nov 16 2020 Overnight conditions will continue to be dominated by high pressure the high pressure air mass with clear skies and dropping temperatures. Low temperatures are still anticipated to be in the low to mid 40s over inland areas and in the upper 40s and 50s and long the coastline. Clear skies with much cooler temperatures for tonight as winds drop off over inland areas. Lows will range from the low/mid 40s over inland areas to the upper 40s to upper 50s coast where winds will stay up overnight. Highs on Tuesday will be mostly in the lower 70s.
Tuesday will be warmer and less windy as strong warm air advection develops with southerly return flow.
201 PM MST Mon Nov 16 2020 Warmer temperatures are expected tomorrow behind a warm front that will move through overnight tonight. Winds will accompany the warmer temperatures tomorrow, with gusts to 35 mph possible along the ridges of the southwest and around the Little Belt Mountains.
Given the building ridge, we can expect clear skies in the afternoon with highs ranging from 55 to 61 degrees. Mid-Week Warming Downsloping flow in the lee of the Rockies (contributing to positive 850 mb temperature anomalies of 10 to 20 degrees C), weak ridging aloft, and southerly surface flow will induce a warming trend during this period.
316 PM CST Mon Nov 16 2020 A backdoor cold front across MT and ND this afternoon will drift into wrn and ncntl Nebraska tonight and become stationary across ncntl Nebraska Tuesday. This frontal position is based on the WPC forecast and high temperatures Tuesday north of the front use the cooler short term model blend. The warmer guidance blend plus bias correction is in place south of the front.
Overnight lows are progged to reach the low to mid 30s.
524 PM CST Mon Nov 16 2020 Ridging aloft will slide eastward across the Plains during Tuesday.
645 PM EST Mon Nov 16 2020 High pressure will build east from the Midwest with cooler and drier air. A dry, cold front will move through the region Tuesday bringing cooler temperatures to the area through mid week. Clear skies will dominate the region tonight as high pressure continues to move into the area. Expect overnight lows to be in the upper 30s to near 40, possibly cooler in sheltered areas. High pressure will continue to ridge into the area with an approaching reinforcing cold front. Weak dry cold front will pass through the area late Tuesday. While radiational cooling will be limited with boundary layer winds remaining elevated, cold air advection will bring lows into the low to upper 30s.
330 PM CST Mon Nov 16 2020 A cold front has dropped into northeast sd and west central mn this afternoon bringing falling temperatures along with stratocu/stratus. With the cooler air remaining in the northeast cwa through much of Tuesday along with the clouds, highs will only reach the upper 30s with upper 50s in the southwest under sunny skies. On Tuesday night, much warmer air will be riding over the cooler surface air through the night strengthening the inversion.
935 PM EST Mon Nov 16 2020 A dry cold front will move through the area on Tuesday, bringing substantially cooler and windy conditions.
946 PM EST Mon Nov 16 2020 Cold front crosses late tonight, with gusty winds and mountain snow showers through Tuesday night.
831 PM CST Mon Nov 16 2020 There's a back-door cold front hanging out (from northwest to southeast) across the CWA, barely moving now, but making the differences in airmasses apparent. A cold front has dropped into northeast sd and west central mn this afternoon bringing falling temperatures along with stratocu/stratus. With the cooler air remaining in the northeast cwa through much of Tuesday along with the clouds, highs will only reach the upper 30s with upper 50s in the southwest under sunny skies. On Tuesday night, much warmer air will be riding over the cooler surface air through the night strengthening the inversion.
/Issued 202 PM CST Mon Nov 16 2020/ Sunny skies and unseasonably warm temperatures are the rule across eastern Oklahoma and western Arkansas this afternoon as high pressure prevails.
Warmer temperatures are expected tomorrow behind a warm front that will move through overnight tonight. Winds will accompany the warmer temperatures tomorrow, with gusts to 35 mph possible along the ridges of the southwest and around the Little Belt Mountains.
Despite lingering pressure gradients last night, several valley locations completely decoupled and dropped into the low 30s. Nudged the lows tonight downward just a tad, leaning towards the colder (at least in the valley) MET and Canadian MOS guidance. Inbound cold front will sweep through the forecast area during the morning hours.

752 PM MST Mon Nov 16 2020 Warmer temperatures are expected tomorrow behind a warm front that will move through overnight tonight. Winds will accompany the warmer temperatures tomorrow, with gusts to 35 mph possible along the ridges of the southwest and around the Little Belt Mountains.
947 PM EST Mon Nov 16 2020 Isolated snow bands will bring 2 to 3 inches of snow to the ridges and areas north of I-80 tomorrow. A A coupled polar jet will continue to provide the necessary ascent for lake enhanced snow showers for northern PA in conjunction with upslope snow showers for the ridges. With a steady thermal profile and no warm air intrusion aloft, expect a transition back to rain during the day Tuesday in places where the high surface temperature surpasses around 34 degrees, namely south of I80 and west of the Laurel Highlands. Snow totals will be highest in Venango and Forest counties and in the ridges, where the moisture profile will reach through the dendritic growth zone via supported large scale forcing.
514 PM CST Mon Nov 16 2020 A backdoor cold front across MT and ND this afternoon will drift into wrn and ncntl Nebraska tonight and become stationary across ncntl Nebraska Tuesday. This frontal position is based on the WPC forecast and high temperatures Tuesday north of the front use the cooler short term model blend. The warmer guidance blend plus bias correction is in place south of the front.
849 PM CST Mon Nov 16 2020 (This evening through Tuesday) Generally mild temperatures, light variable to southerly winds, and clear skies will continue through the short term as the ridge gradually builds over the area.
500 PM CST Mon Nov 16 2020 At 130 PM, low pressure was located over western Wisconsin, with an area of snow located to the northeast of the low across north- central into northeast Wisconsin. As low pressure pushes farther southeast this afternoon, snow should taper off quickly over north-central Wisconsin. Winds will continue to be gusty across northeast Iowa and southeast Minnesota in the tight gradient behind the departing low-pressure system. High pressure will begin to nudge into the area later this evening, very gradually diminishing the cloud cover and allowing gusty west-northwest winds to die down. This high pressure remains in control for Tuesday, with a dry but cool day expected.
Temperatures will start off on the cool side today with northwest flow aloft and high pressure building in at the surface. Expect highs in the upper 40s north to middle 50s south, which is on the warmer side of guidance given the full sunshine expected.
1112 PM CST Mon Nov 16 2020 A backdoor cold front across MT and ND this afternoon will drift into wrn and ncntl Nebraska tonight and become stationary across ncntl Nebraska Tuesday. This frontal position is based on the WPC forecast and high temperatures Tuesday north of the front use the cooler short term model blend. The warmer guidance blend plus bias correction is in place south of the front. This allows for radiational cooling and is cooler than the short term model blend by a few degrees. The temperature forecast is blend of the record setting guidance and the cooler model blend.
/issued 253 PM CST Mon Nov 16 2020/ Skies remain sunny across the Mid-South this afternoon with temperatures in the low to mid 60s. High pressure will remain over the southern U. Temperatures will be cooler than normal tonight with lows Tuesday morning from the mid 30s to lower 40s. A cold front will drop south into the region on Tuesday. Temperatures will be a few degrees cooler on Tuesday with highs in the mid 50s to mid 60s. High pressure will build back into the region by Tuesday night with continued dry weather. High pressure will remain over much of the southeast U.
1143 PM CST Mon Nov 16 2020 Skies will be mostly clear tonight with the winds shifting from the southwest to the northwest overnight as a cold front moves through the region. High temperatures will be cooler on Tuesday, in the 40s.
1133 PM CST Mon Nov 16 2020 An upper level high pressure ridge will build overhead today and edge slightly east by this evening.
This is due to our area being sandwiched in between an area of high pressure to our southwest and a trough to the northeast. Temps will max out in the low to upper 50s. This yields RH values ranging from the low to upper 30s for most areas so it will feel quite dry today. Another thing to note, anyone with outdoor activities planned across the higher elevations need to plan accordingly.
BT Snow showers over the western mountains will decrease into the evening as a mid level warm front lifts north through the region. Otherwise, expect ridging to persist over the area through Tuesday bringing mainly dry conditions. Not a great deal to focus on for a strong chance of precipitation for the lower elevations.
Clear skies and much cooler temperatures can be expected through that time.
246 AM EST Tue Nov 17 2020 High pressure advancing from the mid-Mississippi to Wabash Valley today will provide us with brisk northwest breezes and cool temperatures. Tonight the high will strengthen and move right overhead with light winds and mostly clear skies. Went on the cool side of guidance because of this, and took our eastern sheltered valleys down into the lower 20s. After a cold start Wednesday morning, high temperatures in the afternoon will remain a bit below normal reaching the low/mid 50s with a few upper 40s across the Bluegrass.
This evening through Tuesday night Ridging will build across Wyoming this afternoon and Tuesday leading to a pleasant couple of days. The ridge and associated southwest flow will also bring in some warm air aloft. A Pacific trough and associated cold front will be on the doorstep of western Wyoming early Wednesday, with snow falling by sunrise.
400 AM EST Tue Nov 17 2020 A dry cold front will move through the area today, bringing substantially cooler and windy conditions.
Winds will be light and generally southeasterly though a weak cold front in the area may produce more easterly winds at MAF/HOB before becoming southeasterly again around 15Z. An upper level ridge over the CA/AZ will move eastward and will be centered over the southern High Plains by late tonight. High pressure and southerly return flow will maintain above normal temperatures helping temps reach the upper 70s area wide and 80s for the Rio Grande. Wednesday, southerly return flow and building high pressure will usher in above normal temperatures into the end of the week. An upper level trough will flatten the upper level ridge as it progress eastward this coming weekend.
Noticeably cooler and drier air is in place behind a cold front, with high temperatures generally in the 70s and lower dew points leading to very pleasant conditions each day through the rest of the week.
High pressure, centered just south of the area, will keep a ridge in place through tonight. As the high slides to the east tonight into Wednesday, expect winds to increase an shift to the south as the pressure gradient tightens across the area. Some moderation is expected with the south winds on Wednesdays as temperatures warm into the low 40s.
There have been no significant changes to the near term forecast this evening, as dry northwest flow aloft will prevail across the TN Valley, in the wake of a longwave trough moving slowly across the Eastern CONUS. At the surface, a reinforcing cold front (currently across southeastern MO/southern IL) will advance southeastward, sweeping across the local forecast area in the 07-11Z timeframe. Moderate cold air advection will keep temps noticeably cooler tomorrow afternoon with highs only in the upper 50s to around 60 (a few degrees cooler atop the Cumberland Plateau). High pressure will drop into the middle OH valley Tuesday night into early Wednesday. The high will shift into the mid Atlantic states Wednesday night. A few valley locations may dip into the lower 30s again in the typical cold pockets, while middle 30s are expected elsewhere.
(21Z Today through Wednesday) Currently a weak cold front sits just to the NW of the KC metro, cutting though SE Kansas, NW Missouri, and into SE Iowa. Temps are still expected to climb into the lower to mid 60s this afternoon. This front's main impact will come on Tuesday, knocking the morning low into the lower 30s and Tuesday's high into the 50s across the forecast area. An upper level ridge will gradually build over the western CONUS on Tuesday, making its way east throughout the course of the week.
1235 AM EST Tue Nov 17 2020 High pressure will build east from the Midwest with cooler and drier air. A dry, cold front will move through the region Tuesday bringing cooler temperatures to the area through mid week. Clear skies will dominate the region tonight as high pressure continues to move into the area. Expect overnight lows to be in the upper 30s to near 40, possibly cooler in sheltered areas. High pressure will continue to ridge into the area with an approaching reinforcing cold front. Weak dry cold front will pass through the area late Tuesday. While radiational cooling will be limited with boundary layer winds remaining elevated, cold air advection will bring lows into the low to upper 30s. A much cooler airmass will settle over the area Wednesday with highs likely remaining in the mid to upper 50s.
1008 PM MST Mon Nov 16 2020 Fast northwesterly flow aloft has developed over the forecast area today between an upper ridge over the western CONUS and an upper trough over the east. A tight surface pressure gradient associated with a low pressure center moving from the eastern Dakotas into southern Minnesota is producing gusty northwesterly winds this afternoon. For tonight through Wednesday, the upper level ridge will build eastward over the northern plains. The strongest warm air advection will be Tuesday night in association with the passage of a lee trough. High temperatures will range from 10 to 15 degrees warmer than average on Tuesday and even warmer on Wednesday.
1123 PM CST Mon Nov 16 2020 Ridging aloft will slide eastward across the Plains during Tuesday. On Wednesday, westerly component downslope warming off the high Plains will advect further eastward across central Kansas resulting in high temperatures approaching record levels. Stronger south to southwest surface winds will flirt with or exceed windy advisory criteria over much of the area, with the highest confidence along the turnpike corridor.
(Today and tonight) Upper ridge builds out across the Plains today with mild temperatures and another day with abundant sunshine. Winds will increase some today as pressure falls occur across the high Plains in advance of developing western trough. Winds will stay up some overnight and temperatures will remain several degrees warmer than the last several nights.
High pressure continues to dominate the weather with dry air the main subject.
330 AM EST Tue Nov 17 2020 A cold front will bring scattered rain and snow to region today with accumulating snow along and north of Interstate 80 corridor and in the ridges tonight. Dry conditions and warmer temperatures are expected during the second half of the week. Any accumulation will be minimal with air temperatures largely above freezing and ground temperatures in the lower 40s. Overall, snow totals by Wednesday morning will be highest in the aforementioned counties and in the ridges. Any remaining snow shower activity will come to an end Wednesday morning as ridging moves in from te west. Dry conditions and warmer temperatures will then prevail the remainder of the week with high pressure in control.
1031 PM MST Mon Nov 16 2020 Very few clouds are visible across the CWA this afternoon, thanks to a ridge of high pressure and dry airmass building overhead. Tonight, a deepening low pressure system spinning along the Pacific Northwest will help amplify and shift the ridge eastward, pushing the high directly overhead. The ridge axis will be well east of the Rockies by Wednesday morning, due to the expansive trough lifting into the Western CONUS.
High pressure continues to be the main influence over South Central Texas tonight. High pressure will remain in place through this period.
Temps look to be a little cooler tonight and Tuesday, but cold air advection very weak behind this system.
1145 PM CST Mon Nov 16 2020 High pressure, clear skies and VFR conditions will continue through the period. Tonight through Wednesday Benign weather will continue through the period as high pressure, both aloft and on the surface will continue to dominate.
251 AM CST Tue Nov 17 2020 Today will feel a bit cooler than yesterday as a weak backdoor cold front pushes through the area tonight. The northerly winds and cooler airmass will be more noticeable over norther central Missouri with highs in the upper 40s to lower 50s, but the KC Metro will feel the effects too with highs in the mid to upper 50s. This cool down will be brief as upper level ridging and strong southerly return flow in the low levels builds into the region Wednesday. This higher wind combined with lower relative humidity will increase fire danger along the KS/MO border and burning is not recommended. The higher winds will come with WAA though as our high temps get into the upper 60s with some pockets of 70s in NW Missouri.
249 AM CST Tue Nov 17 2020 A weak cold front currently sitting just to the north will slip south of the mid-state this morning and bring us a shot of cooler dry air. Aloft an upper ridge starts to build early Wed as well. Upper ridging and SFC/LL high pressure hold right on into late weekend as later on Sun a cold front ahead of an approaching trough moves into the MS river valley. Behind this upper trough, another fast mover is right on its heels, and it will move over the area Tues night. It will be accompanied by a weak SFC/LL trough axis and another shot of moisture so that will keep at least a chance for showers running Sun night through Tue.
The upper level ridge axis currently over the Rockies will slide east and be over the Upper Midwest by late tonight. At the surface, an area of high pressure centered over the Missouri River Valley will slide southeast into the Ohio River Valley overnight. As the area of high pressure moves off to the southeast tonight, the low level flow will turn around to the southwest and start to increase pretty quickly. This is roughly 5 to 10 degrees warmer than normal.
Another clear night with a calm wind will lead to cooler than normal temperatures by morning. On Tuesday, high pressure ridging will strengthen over the area once again, from a high centered over the Ohio Valley. /15/ Quiet weather will prevail through the week as the region will remain under high pressure at the surface and upper ridging aloft.
Despite lingering pressure gradients last night, several valley locations completely decoupled and dropped into the low 30s. Nudged the lows tonight downward just a tad, leaning towards the colder (at least in the valley) MET and Canadian MOS guidance. Inbound cold front will sweep through the forecast area during the morning hours. SR Chattanooga Airport, TN 60 35 57 36 62 / 0 0 0 0 0 Knoxville McGhee Tyson Airport, TN 55 31 54 32 61 / 0 0 0 0 0 Oak Ridge, TN 55 30 54 33 61 / 0 0 0 0 0 Tri Cities Airport, TN 51 25 50 28 61 / 0 0 0 0 0.
Mostly clear skies also continuing behind the boundary should aid in overnight low temps to fall into the 30s over the CWA with the normal cool locations possibly reaching at/just below freezing. With most of these locations having already recorded freezing temperatures will not go with any headlines at this time.
1013 PM MST Mon Nov 16 2020 The main concern with this forecast is the high wind potential again early Wednesday morning through Wednesday evening. The upper level ridge will continue to build over the area tonight into Tuesday.
Mid level ridging extends across the Intermountain region this evening, resulting in a dry and mild airmass across the forecast area. This ridge axis will shift east Tuesday, allowing for an increase in southerly winds through midweek. As such breezy to windy conditions are expected across the western valleys during the day Tuesday, with stronger winds expected Wednesday as an upstream trough begins to move inland.
1001 PM PST Mon Nov 16 2020 A warm front will continue to move north spreading valley rain and high mountain snow through this evening. Tuesday will be warmer and breezy. A cold front brings temperatures back down closer to near normal in the lower 40s by the end of the week.
134 AM MST Tue Nov 17 2020 19Z Water vapor imagery and RAP analysis indicated CWA in broad northwesterly flow aloft with large H5 ridge to the west of the area, centered over the northern Rockies. Weather across the Tri State area will be quiet through the period as aforementioned H5 ridge amplifies and moves over the region. Temperatures will continue to warm and based on how fast todays temperatures reached or exceeded the expected values today, think the warmer solutions pushing into the lower 70s looks reasonable. Strong lee trough will develop Tuesday morning leading to increased southerly winds into the afternoon.
