Aikyam-Lab/Synoptic-Bench huggingface dataset:
(Today and tonight) The warming trend continues as initially zonal flow aloft transitions to a ridging pattern centered over the Gulf. Therefore, we are looking at above-normal temperatures with afternoon readings peaking into the low 80s at most inland locations. With a saturated boundary layer developing beneath a strong subsidence inversion from the aforementioned ridge, a foggy/low stratus pattern is anticipated the next 2-3 days.
1248 AM EDT Wed Mar 22 2023 Dry high pressure moves east and off the Carolina coast tonight and Wednesday as a warm front crosses Tennessee bringing small shower chances to the mountains and foothills on Wednesday.
356 AM CDT Wed Mar 22 2023 The potential for impacts are diminishing across the area this morning as an upper low continues to move to the east. Patchy freezing drizzle have been observed as the dry slot works into the area from the west-southwest. These type of waves could also bring cold frontal passages and brief periods of gusty winds (though there isn't a signal for any push of arctic air) which could bring drifting/blow ice impacts once again.
A trough of low pressure will begin deepening off the coast of the Pacific Northwest, and move inland during the day Thursday.
144 AM EDT Wed Mar 22 2023 Dry high pressure moves east and off the Carolina coast tonight and Wednesday as a warm front crosses Tennessee bringing small shower chances to the mountains and foothills on Wednesday.
This will inhibit radiational cooling overnight, keeping temperatures above freezing. Overnight, a warm front swinging across the ArkLaMiss Delta will increase rain chances along the Highway 82 corridor.
As of early this morning, a quasi-stationary warm front was sharpening up from Interstate 70 in eastern Kansas to central Missouri. Look for the warm front to shift slightly north and become better-defined by mid/late morning. As for temperatures, the warm front is expected to bisect W-E the CWA, including the KC Metro Area. This will provide a notable temperature gradient for highs on today, with maximum readings in the middle 50s near the Iowa border to the lower and middle 70s south of the warm front.
Upper level ridging will build over the Gulf of Mexico and Florida through the week while drifting east and eventually out into the western Atlantic Ocean this weekend as troughing moves across the central and eastern states.
Weak upper wave over MO will shear quickly newd tonight as wrn flank of departing polar ridge holds firm. Ramping LLJ ahead of this will yield fairly vigorous theta-e ridging aloft late evening and overnight with thunderstorms probable beneath steep mid level lapse rate plume. Leading wave and associated sfc reflection looks progressive on Thu with morning showers and perhaps a lingering thunderstorm along cold frontal zone.
High pressure sitting just off the eastern U. Temperatures did start out comfortable in the lower 70s this morning but have quickly risen into the mid to upper 70s with Marathon already reporting 81 degrees as of 10 AM. The aforementioned high pressure will build as it moves across the western North Atlantic. Lack of appreciable cloud cover will allow for temperatures to once again reach into the lower to mid 80s. From synopsis: High pressure centered just off the eastern United States continues moving eastward this afternoon.
Flooding will continue at the lower elevations, especially in eastern Yavapai and northern Gila counties. Convective cells, training cells, CSI banding, a cold front to our west, you name it, it's here! Moisture continues to stream into Arizona from the south, but saturation is much more shallow compared to yesterday and we are just not seeing the ice layer development so far this morning. This will change in the next few hours as the cold front approaches. The pattern becomes much more showery later today, but a mean trough will hang on across the western United States, bringing an unsettled and cool pattern for our area right on into the coming weekend.
A few locations across Cullman County may climb into the lower 70s.
530 AM CDT Wed Mar 22 2023 (Today through Thursday) Scattered SHRA continue to lift NE as moisture lifts north of the warm front. The warm front will lift north of AR by this afternoon. with much warmer conditions expected for this Wed afternoon. A cold front will approach the state from the north Thu afternoon.
702 AM EDT Wed Mar 22 2023 (Today and tonight) The warming trend continues as initially zonal flow aloft transitions to a ridging pattern centered over the Gulf. Therefore, we are looking at above-normal temperatures with afternoon readings peaking into the low 80s at most inland locations. With a saturated boundary layer developing beneath a strong subsidence inversion from the aforementioned ridge, a foggy/low stratus pattern is anticipated the next 2-3 days.
This will then bring a cold front through much of our SRN and ERN portions of the forecast area with the SPC highlighting all of the I-84, I-86, and I-15 corridors south and east to Wyoming and Utah in the risk for general thunderstorms this afternoon and evening. Headed up into the mountains above 6500 feet MSL south and east of the Snake Plain, look for 5 to 10 inches through tonight with higher totals across the highest elevations of the SRN Highlands between 8 to 18 inches.
Key Messages: * Areas of fog and some light drizzle should clear from north to south over the next couple of hours as a cold front helps scour out the lower ceilings and visibilities. * Slightly cooler temperatures behind this front today, but continued seasonable temperatures, variably cloudy skies and east northeasterly breezes of 10 to 25 mph anticipated.
A low pressure system will move across the area today bringing gusty winds, mountain snow and valley rain.
This system combined with the next cold front approaching from the WNW could tighten the pressure gradient enough to produce patchy light rain or drizzle by late tomorrow afternoon and evening. Highs tomorrow should be a bit warmer (given a bit more sun and an increased SW flow at the lower/ mid levels) with temperatures climbing into the mid 80s across much of the region (upper 70s to lower 80s at the coast).
Mainly dry weather is expected this morning with a return of light showers this afternoon and evening over the inland areas as a weak trough passes across the area.
Still expecting the stationary boundary to begin lifting northward through the day with high temps in the low to mid 70s generally south of a line from Rome, to Norcross, to Watkinsville, with highs around 60 further north. Thiem (Today through Thursday) Our weather today and tomorrow will be mainly influenced by high pressure aloft parked over the Gulf of Mexico. Tonight southerly surface flow will help to continue to moisten the lower levels of the atmosphere and as temperatures and dewpoint meet patchy dense fog will be possible across the eastern portions of the CWA late tonight into tomorrow morning. Tomorrow south to southwesterly flow both aloft and at the surface will persist allowing for much warmer and dry conditions across north and central GA.
The cold closed upper low is still spinning near the Bay Area early this morning with numerous showers continuing to rotate up from the south across the southern half of the forecast area.
The potential for impacts are diminishing across the area this morning as an upper low continues to move to the east. Patchy freezing drizzle have been observed as the dry slot works into the area from the west-southwest. These type of waves could also bring cold frontal passages and brief periods of gusty winds (though there isn't a signal for any push of arctic air) which could bring drifting/blow ice impacts once again.
Temperatures currently in the low 70s will gradually warm up to the upper 70s along the East Coast and mid 80s across the southwest. Subsidence provided by the ridge will also inhibit shower development both days.
Current satellite imagery depicted a low pressure center progressing northeastward across Central MN. Given the cooler temperatures from advection to our north, p-type does include light snow potential near the MN/IA border. This weekend features a filling trough to our southwest and as this occurs, another system will develop in the central plains and track to the north northeast.
1040 AM EDT Wed Mar 22 2023 High pressure will pass off the Mid Atlantic coast today.
610 AM CDT Wed Mar 22 2023 Key Messages: - Minor snow accumulations anticipated tonight for areas along and south of I-90 mainly limited to cooler, grassy surfaces. Temperatures remain near seasonable with above freezing conditions during the day and below freezing at night. But heading into tonight, another trough on a more southerly stream compared to this preceding system will bring a return for precipitation chances across the region. However with ground surfaces holding some residual heat into tonight with the daytime temperatures rising well above freezing, accumulations could be drastically limited to only a couple of tenths and mainly on the cooler, elevated and grassy surfaces.
An upper trough will move across the region today resulting in showers continuing across our area through this evening. The trough will move out of our area by Thursday morning. Unsettled conditions will then continue through the weekend with cooler than normal temperatures and mountain showers.
Isentropic lift along the warm front is bringing heavy snow showers to portions of northeast Minnesota and northwest Wisconsin. As the associated warm front with this system moves northward, snow will transition to mix and then rain throughout the morning across our southern CWA as surface temperatures increase. As the main band of precipitation moves off and dry air aloft trails in behind, drizzle or freezing drizzle is possible across our area. Drizzle and freezing drizzle chances will last into the late morning, and, combined with previous snowfall, could cause conditions to be slippery for the morning commute.
624 AM CDT Wed Mar 22 2023 (Today and tonight) Mid-level flow over the southern US was starting to become southwesterly this morning, thanks to a strong trough moving onto the west coast. In the lower levels, strong southerly flow remains steady, with some gulf moisture being fed into the region. Cloud-cover should increase and low temperatures will be in the low to mid 60s.
740 AM EDT Wed Mar 22 2023 Upper level ridging will build over the Gulf of Mexico and Florida through the week while drifting east and eventually out into the western Atlantic Ocean this weekend as troughing moves across the central and eastern states.
Showers will continue through the late night hours and into Wednesday morning as the low gradually moves southward off the Bay Area coastline.
As of early this morning, a quasi-stationary warm front was sharpening up from Interstate 70 in eastern Kansas to central Missouri. Look for the warm front to shift slightly north and become better-defined by mid/late morning. As for temperatures, the warm front is expected to bisect W-E the CWA, including the KC Metro Area. This will provide a notable temperature gradient for highs on today, with maximum readings in the middle 50s near the Iowa border to the lower and middle 70s south of the warm front. Wind direction then becomes difficult beyond this time a warm front will bisect the area in the VC of the TAF sites.
729 AM EDT Wed Mar 22 2023 High pressure will pass off the Mid Atlantic coast today.
715 AM EDT Wed Mar 22 2023 High pressure will pass off the Mid Atlantic coast today.
Temperatures this afternoon will reach the upper 70s at the coast with a sea breeze limitation, but climb to the low to mid 80s across the interior.
425 AM CDT Wed Mar 22 2023 Key Messages: * Areas of fog and some light drizzle should clear from north to south over the next couple of hours as a cold front helps scour out the lower ceilings and visibilities. * Slightly cooler temperatures behind this front today, but continued seasonable temperatures, variably cloudy skies and east northeasterly breezes of 10 to 25 mph anticipated.
615 AM CDT Wed Mar 22 2023 (Today through Thursday afternoon) Current satellite shows a large upper level low near the northern California coast with a strong jet stream located over the southwestern United States.
(Today and tonight) Mid-level flow over the southern US was starting to become southwesterly this morning, thanks to a strong trough moving onto the west coast. In the lower levels, strong southerly flow remains steady, with some gulf moisture being fed into the region. Cloud-cover should increase and low temperatures will be in the low to mid 60s.
Areas northwest of I-44 and west of Highway 75 have the best chance to break out of the clouds today, and along with a westerly component to the low level winds and the warm start to the day, should lead to highs that are 15 to 20 degrees above normal.
1238 PM CDT Wed Mar 22 2023 Key Messages: * Areas of fog and some light drizzle should clear from north to south over the next couple of hours as a cold front helps scour out the lower ceilings and visibilities. * Slightly cooler temperatures behind this front today, but continued seasonable temperatures, variably cloudy skies and east northeasterly breezes of 10 to 25 mph anticipated.
-- Rain, snow, or mix likely Fri night into Sat -- A mid/upper trough emerging from the SW CONUS will spur cyclogenesis over the Southern High Plains on Thu. This may support an area of freezing rain and/or sleet across Lower MI, but the placement of these p-types and related amounts are similarly uncertain. This will be a bit strange in that the low clouds will continue even though a few thunderstorms happen higher up in the atmosphere. On Thu, northerly winds will develop across the lake as high pressure builds across the Northern Plains.
Light winds and generally sunny to partly cloudy skies are expected during this time under brief high pressure.
Instability associated with an upper trough over the region will support scattered snow showers over the higher elevations this afternoon. Surface winds: E-SE 5-15 kt with gusts to 30 kt near the NV border and in the Lower Snake River Plain, becoming W-NW 5-15 kt after 22/17Z.
131 PM PDT Wed Mar 22 2023 The low pressure system off the coast of California will continue to bring rain showers and possibly thunderstorms to the area this afternoon and into this evening.
111 PM CDT Wed Mar 22 2023 Key Messages: - Minor snow accumulations anticipated tonight for areas along and south of I-90 mainly limited to cooler, grassy surfaces. Temperatures remain near seasonable with above freezing conditions during the day and below freezing at night. But heading into tonight, another trough on a more southerly stream compared to this preceding system will bring a return for precipitation chances across the region. However with ground surfaces holding some residual heat into tonight with the daytime temperatures rising well above freezing, accumulations could be drastically limited to only a couple of tenths and mainly on the cooler, elevated and grassy surfaces.
1251 PM CDT Wed Mar 22 2023 (Today through Thursday afternoon) Current satellite shows a large upper level low near the northern California coast with a strong jet stream located over the southwestern United States.
Should see rain transitioning to snow from northwest to southeast during the event as a cold front moves through. It will be a bit cooler Thursday behind the cold front, with lingering clouds into the afternoon.
(Tonight) A warm front lingering over the southeastern US is expected to continue northeast this evening, allowing precipitation to gradually conclude from southwest to northeast of our area. The low temperature tonight is expected to drop into the upper 40s/lower 50s with skies mostly clearing out with the rainfall.
1215 PM CDT Wed Mar 22 2023 (Today and tonight) Mid-level flow over the southern US was starting to become southwesterly this morning, thanks to a strong trough moving onto the west coast. In the lower levels, strong southerly flow remains steady, with some gulf moisture being fed into the region. Cloud-cover should increase and low temperatures will be in the low to mid 60s.
Inverted trough will push off to the northeast throughout today and tonight with high pressure ridging and dry weather settling in over the southeastern US. High temperatures this afternoon will reach up into the lower to mid 80s for inland areas and in the mid 70s along the coastline. Overnight low temperatures will drop down into the mid 50s for inland areas and in the lower 60s along the shoreline. High pressure ridging will maintain over the region through the end of the week resulting in dry weather, mild winds, and predominantly clear skies. Temperatures will warm to near record level highs for the end of the week with daily max temps reaching up into the upper 80s and lower 90s for inland areas and in the lower 80s along the coast.
1231 PM EDT Wed Mar 22 2023 High pressure will pass off the Mid Atlantic coast today.
114 PM MDT Wed Mar 22 2023 Current upper air analysis shows split for for the western NOAM, with ridging over west Canada and trough over the CA/NV region, converging near our area. At the surface, high pressure sits over eastern SD, while a warm frontal boundary sits west/east oriented over southern WY. Farther north and east precip will struggle to overcome the dry high pressure air.
349 PM EDT Wed Aug 16 2023 A cold front will linger over the region into Thursday.
Heat risk values continue to look marginal for Thursday, given that temperatures are not appreciably warmer and most of the area is cooling into the 50s or low 60s will likely hold off on heat headlines. The high resolution models are showing isolated development late Thursday afternoon across south Idaho spreading into east Idaho into Thursday evening.
That said, conditions will be much more comfortable than past weeks with dewpoints in the low 60s across much of GA.
1223 PM CDT Wed Aug 16 2023 Today through tonight: An upper level trough is helping to maintain a more comfortable, less humid airmass over the forecast area in the near term. /EC/ Thursday through this weekend: Temperatures will start to rise once again as the more comfortable airmass (which gave us some well needed relief from the heat) will start to get replaced by a strengthening ridge located across the southern Great Plains. The ridge will gradually make its way eastward throughout the weekend, keeping us mainly dry and hot.
202 PM EDT Wed Aug 16 2023 A cold front will linger across the area through Thursday, then move offshore as high pressure builds in from the west.
High temperatures will remain in the lower 80s with dew point temperatures remaining comfortable in the lower 60s. This period of warmer and humid conditions will be short-lived.
This low level moisture has allowed for cumulus to develop across the eastern portions of the area this afternoon. High pressure has moved off to the east and winds have turned southerly.
The low-level winds combined with warmer air aloft moving over the area from the ridge will cause an increase in high temperatures to upper 90s to low 100s Thursday. Due to the high temperatures and heat persisting into the evening, a heat advisory has been issued for Thursday from noon MDT to midnight MDT for much of south central MT.
/21 (Now through Thursday) A much drier airmass will continue to filter into the region today as an upper level trough moves across the area. Dewpoints will fall into the low to mid 60s inland to low 70s along the coast. High temps will also be cooler today with upper 80s and low 90s. A large upper ridge begins to build eastward from the southern plains into the southeast on Thursday with temps warming back into the mid 90s.
Otherwise, hotter Thursday with highs of 105 to 110, as high pressure aloft intensifies over the region. (Thursday night through next Wednesday) Excessive heat will be firmed entrenched across West Central Texas through the weekend, as the upper level high re-establishes itself over the Plains.
219 PM CDT Wed Aug 16 2023 (Today through Thursday afternoon) Following the slightly cooler airmass we saw the last couple days temperatures will be on the way back up. Upper ridging centered to our northwest will remain in control of our weather. Highs will return to the 100s for most this afternoon with low to mid 90s into the higher terrain. Isolated storms are once again possible for the higher terrain and portions of southeast New Mexico.
(This evening through Thursday) Mid/upper-level ridging continues to drift eastward over the southern Rocky Mountains this afternoon with subsident air present over the TX PH and South Plains. The contribution of adiabatic compression from the southwesterly breeze will result in a warm night with temperatures in the lower 70s across most of the Caprock while running a few degrees warmer in the Rolling Plains. The weakening cold front will move through the CWA by tomorrow afternoon, and with the lee cyclone nearby, winds will veer throughout the course of the day. Increasing geopotential heights from the core of the ridge moving overhead, in addition to very deep mixing in the boundary-layer (i.
1136 AM EDT Wed Aug 16 2023 A cold front will stall over the area through mid week bringing widespread showers and thunderstorms and cooler temperatures. A cold front should progress into SE NC and NE SC early this AM before stalling out as heating commences after daybreak. Low temperatures should fall back mainly into the lower to mid 70s.
1248 PM CDT Wed Aug 16 2023 (Today through Thursday) Early this morning, an upper trough extended from Lake Ontario to near Memphis, southwestward into east Texas. Upper ridging was centered near the Four Corners area. At the surface, the frontal boundary associated with last night's thunderstorms was noted over the lower portions of the southeast Louisiana coastal parishes. Dew points were in the lower and middle 60s west of a line from Bogalusa to Metairie, and in the lower and middle 70s to the east of that line. The upper trough axis is only shifting slowly to the east of the area, and may not get fully east of the area until the daytime hours on Thursday. Highs on Thursday should be 3-5F warmer with mid and upper 90s expected.
1024 AM CDT Wed Aug 16 2023 Skies are mostly sunny across the Mid-South this morning with temperatures in the low to mid 70s. Upper level ridging will allow for dry weather to continue for the coming days. As the ridge intensifies, heat and humidity will return and heat headlines are likely to make their return this weekend.
227 PM CDT Wed Aug 16 2023 Fair weather is expected this evening through tonight under the influence of high pressure along the Ohio Valley. A cold front will sweep across central Illinois Thursday morning and afternoon. Expect highs in the lower to mid 80s.
High pressure continues to sit to our NW resulting in mostly clear skies.
Fair weather conditions are in place under the influence of high pressure in place along the lower/mid Mississippi Valley into the Midwest. As it propagates eastward, drier and cooler weather continues for central Illinois today. Tomorrow, a low pressure system is expected to track far north of central Illinois up across Canada. A cold front will extend southward and traverse across the central Illinois area through the day.
(This afternoon through Thursday) 1000-500mb mean RH has fallen to around 30% in the wake of the cold front which is now situated generally east to west along the Gulf Coast. Temperatures will begin to gradually rise again by the end of the week, but for now, we'll gratefully accept dewpoints in the low/mid 60s, highs in the mid 80s to lower 90s with mostly sunny skies, and overnight lows in the 60s.
(This afternoon through Thursday night) There isn't very much to talk about in the short term as the upper ridge builds and thickness increases today and tomorrow.
226 PM EDT Wed Aug 16 2023 Dry high pressure will maintain milder temperatures and lower humidity to the end of the week.
