Aikyam-Lab/Synoptic-Bench huggingface dataset:
Cold front currently moving through northern portions of the state. Pre- frontal trough associated with an area of precipitation is exiting the CWA to the southeast. A cold front associated with the system is currently located over northern Alabama and should be entering Northwest GA over the next couple hours. The cold front should make it through the ATL metro by around 15Z with post frontal conditions significantly drier. Patchy fog may thicken north of I20 over the next several hours, particularly in the higher elevations of North GA. Highs will remain in the upper 50s to low 60s and lows will stay in the 30s and 40s (above freezing).
A weak cold front moves in after Midnight, bringing a northerly wind shift to most areas by sunrise Monday.
350 PM EST Sun Dec 3 2023 Low pressure moving through the Upper Ohio River valley will move into New York State tonight. The associated cold front will push this evening and bring cooler air for tonight and Monday.
710 PM EST Sun Dec 3 2023 Cooler and drier weather will arrive behind a cold front tonight.
Expect afternoon temperatures to peak in the low to mid 60s.
623 PM EST Sun Dec 3 2023 (Through Monday) A cold front moving slowly eastward across the area today will finally clear the region tonight. Light west to northwest winds are expected in the wake of the front, with slightly cooler and drier conditions expected.
- Diminishing Rain and Snow This Afternoon/Evening The area of low pressure over Southern Lower MI will pull off to the east tonight. With temperatures remaining above freezing to start the evening, the potential for impacts is low. We do fall below freezing overnight so there could be a few icy spots on untreated surfaces then. Forecast soundings support mainly snow and surface temperatures will be below freezing.
Low temperatures fall into the lower to upper 20s.
This cirrus deck will continue to gradually clear from NW to SE this evening through the overnight hours as a reinforcing cold front advances southward and ushers in some cooler and drier air. High temperatures will be a bit milder with upper 50s to lower and middle 60s due to the cooler air mass following tonight's frontal passage.
(This afternoon through Monday) Surface analysis shows a pre-frontal trough across far southeast GA this afternoon with a cold front across northern portions of the state. A secondary dry cold front is currently cross the Mississippi River. The secondary front will also bring much drier and cooler airmass to the area.
635 PM EST Sun Dec 3 2023 A cold front will pass through the area tonight.
529 PM CST Sun Dec 3 2023 (This evening through Monday) The cold front has cleared Central Alabama with westerly flow at the surface. A fast moving area of low pressure just to our north with a trailing cold front will move west to east across the region during the day on Monday. A reinforcing shot of cooler and drier air will move in behind the dry front with breezy westerly to northwesterly winds gusting between 20 and 25mph at times.
227 PM MST Sun Dec 3 2023 A strong ridge of high pressure will build over the region during the first part of this week leading to a steady warming trend.
Key Points: * Light rain or light snow expected tonight mainly focused between the highway 36 to I-70 corridors. * Warmer and drier conditions expected mid-week leading to a slightly elevated fire danger. 12Z models have trended south with this wave, and have focused the bulk of the accumulations between the highway 36 and I- 70 corridors through the evening hours.
542 PM CST Sun Dec 3 2023 (The rest of this afternoon ) Cold front currently into NW OK will sweep quickly eastward this evening with breezy northerly winds following.
However am not anticipating any travel impacts for the morning commute as surface temps remain above freezing where precip is occurring. Once the system departs, a return to cool/dry weather is expected by Monday afternoon with high temperatures topping out in the lower to middle 40s.
A series of cold fronts will move through the region over the next couple of days. The first cold front will move across the Mid- South late tonight.
558 PM CST Sun Dec 3 2023 (This evening through Monday) As of 3:15PM, a weak cold front was draped from Lahoma to near Butler with northwest winds gusting 35 mph to occasionally 40 mph. Tomorrow, mid-level heights rise and the center of high high pressure tracks across the Texas panhandle and then western north Texas.
133 PM PST Sun Dec 3 2023 Building high pressure will lead to warming through the first half of the week. A trough will move inland across the Pacific Northwest late week, leading to winds turning back onshore in Southern California, as well as cooler conditions and a brief rebuilding of the marine layer. The only impact this will have is on the sunset, so be sure to catch what is shaping up to be a colorful evening sky! A building ridge of high pressure is closing in on the western United States today.
(Now through Monday) Drier and cooler conditions will return as the cold front moves through the area. Rain has cleared as the cold front slowly pushes east. A cooler and drier airmass will move into the area behind the front this afternoon and evening.
628 PM EST Sun Dec 3 2023 Aviation - Diminishing Rain and Snow This Afternoon/Evening The area of low pressure over Southern Lower MI will pull off to the east tonight. With temperatures remaining above freezing to start the evening, the potential for impacts is low. We do fall below freezing overnight so there could be a few icy spots on untreated surfaces then. Forecast soundings support mainly snow and surface temperatures will be below freezing.
549 PM CST Sun Dec 3 2023 A series of cold fronts will move through the region over the next couple of days. The first cold front will move across the Mid- South late tonight.
620 PM CST Sun Dec 3 2023 The main update to the grids was to insert sprinkle mention across NE OK into NW AR in association with upper low moving across KS into MO. Cold front/wind shift has entered NE OK early this evening and will progress east/south tonight. Lacy (The rest of this afternoon ) Cold front currently into NW OK will sweep quickly eastward this evening with breezy northerly winds following.
A strong ridge of high pressure will build over the region during the first part of this week leading to a steady warming trend.
953 PM EST Sun Dec 3 2023 Cooler and drier weather arrives behind a cold front tonight.
This extension is mainly for the highest elevations of the central mtns, mainly north of Cottonwood Pass. Valleys will fall into the 10s, Interestingly enough, temps at the higher elevations of the mtns tonight will be several degrees warmer than this mornings mins as warm air aloft pushes into the region.
818 PM CST Sun Dec 3 2023 A few showers may impact portions of northwest Tennessee overnight as a low pressure system and attendant cold front move over Kentucky. By midday, the front will be through the region with slightly cooler air settling over the Mid-South.
(This evening through Monday) As of 3:15PM, a weak cold front was draped from Lahoma to near Butler with northwest winds gusting 35 mph to occasionally 40 mph. Tomorrow, mid-level heights rise and the center of high high pressure tracks across the Texas panhandle and then western north Texas.
312 PM CST Sun Dec 3 2023 Key Points: * Light rain or light snow expected tonight mainly focused between the highway 36 to I-70 corridors. * Warmer and drier conditions expected mid-week leading to a slightly elevated fire danger. 12Z models have trended south with this wave, and have focused the bulk of the accumulations between the highway 36 and I- 70 corridors through the evening hours.
447 PM CST Sun Dec 3 2023 (This evening through Monday night) Upper level trough continues to swing across Kansas leaving a quick push of cold air in it's wake. The cold front is moving south about 35 mph will likely be through most of the Panhandles by 6 pm. Moving to overnight, light and variable winds with a gradual shift to the southwest tomorrow afternoon as some warmer air tries to briefly squeak into the area under the continued dominate northwest flow pattern. A secondary system with a positive tilt will push through Kansas Monday night with another weak cold front trailing, and that will shift winds out of the north again Monday night.
Not much motion eastward has occurred in the lowest level stratus deck over the last two hours so it may stick around longer than initially forecast. The primary impact as a result of this may be slightly warmer temperatures in the valley, but other than that no other impacts are expected. East of this trough, low clouds are contributing to aviation impacts (see Aviation Discussion for more information).
846 PM EST Sun Dec 3 2023 A cold front will move through the region this afternoon.
526 PM CST Sun Dec 3 2023 (Rest of Today and Tonight) Morning low clouds have begun to erode as yesterdays cold front continues to push east into the mid Atlantic. Under high pressure, mostly clear conditions will allow for temperatures to cool off quickly after sunset. High clouds filtering in from the NW around midnight is what will keep us well above freezing with lows in the low 40s and high 30s.
538 PM CST Sun Dec 3 2023 (This evening through Monday) Breezy conditions will continue through early this evening in the wake of a weak upper-level disturbance tracking across the area this afternoon, and ahead of a trailing weak cold front that will make its way across the region tonight. Once the weak cold front passes through tonight, winds will briefly shift to north to northwesterly and become light and variable overnight. Overnight lows are likely to dip back down into lower 30s to lower 40s, with a few low lying areas falling below the freezing mark for a few hours during the overnight and early morning hours.
1059 PM CST Sun Dec 3 2023 (This evening through Monday) The cold front has cleared Central Alabama with westerly flow at the surface. A fast moving area of low pressure just to our north with a trailing cold front will move west to east across the region during the day on Monday. A reinforcing shot of cooler and drier air will move in behind the dry front with breezy westerly to northwesterly winds gusting between 20 and 25mph at times.
Still seeing light to moderate snow across the far SE along with difficult road conditions and thus we will allow the Winter Storm Warning to ridge there overnight. Across the higher terrain though, especially across the southern and eastern highlands, snowfall amounts of an additional 2-6 inches are likely through the evening. 6-15 inches across the highest terrain seems reasonable and Winter Storm Warnings remain in effect to account for this. Clouds will stick around tomorrow but temperatures continue to warm with highs ranging from the upper 30s to mid 40s for much of the area which should allow for some ample melting of the snowpack, especially in the lower valleys.
1055 PM CST Sun Dec 3 2023 (Rest of tonight) Dry weather will persist overnight with the cold front now positioned well to our south. A weak and moisture starved low will track east over the lower OH River Valley into tomorrow morning, but with the best moisture and forcing positioned well to our north, the only impact we will see from this is additional cloud cover and increasing winds overnight.
1047 PM CST Sun Dec 3 2023 (This evening through Monday) Breezy conditions will continue through early this evening in the wake of a weak upper-level disturbance tracking across the area this afternoon, and ahead of a trailing weak cold front that will make its way across the region tonight. Once the weak cold front passes through tonight, winds will briefly shift to north to northwesterly and become light and variable overnight. Overnight lows are likely to dip back down into lower 30s to lower 40s, with a few low lying areas falling below the freezing mark for a few hours during the overnight and early morning hours.
Primarily, the low spreads light rain chances along its track, mainly across our north the first half of the day, where we remain warm enough for all rain. This promotes another low's clipper-like drop into/across the area late tonight into early tmrw, but we're largely moisture starved so pops will be chance category and confined primarily to our far north and east along and nearest to the low's track.
A cold front has made its way southward through west central Texas overnight. Clear skies with fairly weak winds should allow temperatures to fall to the mid 30s for most areas while low-lying locations could drop below freezing.
Northwest winds will increase to 10 to 15 mph behind the front with temperatures forecast to fall into the mid 30s across the I-30 corridor to the low to mid 40s across north Louisiana and Deep East Texas. The warmer temperatures south of I-20 can be attributed to the later timing of cool air advection along with a lingering high cirrus deck that is forecast to erode through the early morning hours. This cirrus deck will continue to gradually clear from NW to SE this evening through the overnight hours as a reinforcing cold front advances southward and ushers in some cooler and drier air. High temperatures will be a bit milder with upper 50s to lower and middle 60s due to the cooler air mass following tonight's frontal passage.
A ridge of high pressure, currently off the California coast, builds into the southwestern CONUS over the next few days. A weak disturbance will push through the region on Monday, just ahead of the high and bring some gusty winds down the lower Colorado River Valley. As the high builds, we will see lighter winds along with increasing temperatures.
1235 AM EST Mon Dec 04 2023 A cold front will move southeast across eastern NC tonight.
Dry conditions are expected by noon with brief ridging.
Early morning IR and water vapor satellite imagery is showing a band of cirrus clouds streaming across northern Florida associated with a slow moving cold front.
The mean layer ridge which ruled the weather across the Florida Keys the past few days is under assault from lower heights to the northwest. A cold front bisects the northern Gulf Coast. NASA SPoRT SST data suggest SSTs are about five degrees cooler adjacent to Mainland Monroe and Collier County, where VIS sensors and webcams observe fog.
After above normal temperatures today, cooler weather in store for mid week. A cold front moved offshore several hours ago with westerly winds now bringing in drier and slightly cooler air. With drier air and clearer skies tonight lows should fall into the lower 40s inland and mid 40s near the coast.
(Rest of tonight) Dry weather will persist overnight with the cold front now positioned well to our south. A weak and moisture starved low will track east over the lower OH River Valley into tomorrow morning, but with the best moisture and forcing positioned well to our north, the only impact we will see from this is additional cloud cover and increasing winds overnight.
1244 AM EST Mon Dec 4 2023 Drier air will arrive as a cold frontal passes across the area late tonight.
1035 PM CST Sun Dec 3 2023 (This evening through Monday night) Upper level trough continues to swing across Kansas leaving a quick push of cold air in it's wake. The cold front is moving south about 35 mph will likely be through most of the Panhandles by 6 pm. Moving to overnight, light and variable winds with a gradual shift to the southwest tomorrow afternoon as some warmer air tries to briefly squeak into the area under the continued dominate northwest flow pattern. A secondary system with a positive tilt will push through Kansas Monday night with another weak cold front trailing, and that will shift winds out of the north again Monday night.
1038 PM CST Sun Dec 3 2023 (This evening through Monday) As of 3:15PM, a weak cold front was draped from Lahoma to near Butler with northwest winds gusting 35 mph to occasionally 40 mph. Tomorrow, mid-level heights rise and the center of high high pressure tracks across the Texas panhandle and then western north Texas.
Lows tonight will be in the lower to middle 30s. Highs on Monday will range form the lower 40s north to the mid and upper 40s in the south. Short wave ridging will shift quickly east across our area Monday night before yet another mid level short wave approaches from the west late. Lows Monday night will be in the low to mid 30s.
325 AM EST Mon Dec 4 2023 A cold front will move offshore later today, with high pressure building in for tonight.
1139 PM CST Sun Dec 3 2023 Key Points: * Light rain or light snow expected tonight mainly focused between the highway 36 to I-70 corridors. * Warmer and drier conditions expected mid-week leading to a slightly elevated fire danger. 12Z models have trended south with this wave, and have focused the bulk of the accumulations between the highway 36 and I- 70 corridors through the evening hours.
1050 PM CST Sun Dec 3 2023 The main update to the grids was to insert sprinkle mention across NE OK into NW AR in association with upper low moving across KS into MO. Cold front/wind shift has entered NE OK early this evening and will progress east/south tonight. Lacy (The rest of this afternoon ) Cold front currently into NW OK will sweep quickly eastward this evening with breezy northerly winds following.
Western NOAM ridge will shift east in the period and offer mild and dry weather for most of the week. Upper ridge will shift east supporting increasingly warmer weather the next couple days. Upper trough will then advect into the western CONUS by the end of the week, with this system expected to support a return back to progressive NW flow, supporting cooler conds, along with some low chances for snow showers with passing impulses.
(Today and tonight) Water vapor imagery currently shows the upper level trough over the central Midwest where it is expected to track into the eastern region by Monday afternoon. Tonight as the next upper level system digs southward an associated cold front will quickly sweep through the FA.
1139 PM EST Sun Dec 3 2023 Low level troughing will sustain areas of IFR based clouds, mainly from PTK northward through at least 08 or 09Z. This low level troughing will weaken during the course of the morning and will allow ceilings to be predominately MVFR after 09 or 10Z. A slightly cooler air mass will build into the area in the wake of this disturbance with highs in the upper 30s to around 40 on Monday and lows down into the 20s Monday night.
1126 PM CST Sun Dec 3 2023 A few showers may impact portions of northwest Tennessee overnight as a low pressure system and attendant cold front move over Kentucky. By midday, the front will be through the region with slightly cooler air settling over the Mid-South.
Temperatures will be warmer on Monday with highs 5 to 10 degrees above normal.
1230 AM EST Mon Dec 4 2023 Cooler and drier weather arrives behind a cold front tonight.
The High Wind Warning is still on track to start for SW Phillips at 11 PM MST. However, temperatures will be steady or slightly warmer Monday given a lack of cold air advection and chinook warming effect.
310 AM MST Mon Dec 4 2023 A cold front will move SE across the forecast area early this morning. A warm front moves through the area tonight and models are hinting at some light mixed precipiation in some areas.
Cold front over west central Montana through southern Washington State.
633 AM EST Mon Dec 4 2023 Early morning IR and water vapor satellite imagery is showing a band of cirrus clouds streaming across northern Florida associated with a slow moving cold front.
The result of a cold front which will move south through the region and produce windy conditions with gusts of 35 to 45 mph.
421 AM CST Mon Dec 4 2023 Current surface analysis places low over southeast Saskatchewan, with cold front sweeping from central into eastern Montana. There may be a spot or two of a little bit of an attempt to transition to rain over parts of southwest North Dakota as some warmer air aloft tries to work into the system. Although the cold air advection in the wake of the cold front is quite modest at best, model soundings over far southwest North Dakota still show the potential for ~45kt winds mixing down, so will leave going wind advisory intact.
Continued dry weather with cooler, near normal, temps Tuesday.
528 AM CST Mon Dec 4 2023 (Today through Tuesday) A comfortable start to the week is expected across Deep South Texas with high pressure in control. Highs top off a couple of degrees warmer than yesterday into the upper 70s both today and Tuesday, with lows also gaining a degree or two into the upper 50s or low 60s across the RGV and low 50s across the ranchlands.
212 AM MST Mon Dec 4 2023 A strong ridge of high pressure will build across the region over the next couple days leading to a noticeable warming trend. By Tuesday, afternoon high temperatures across the lower deserts will top out in the mid to upper 70s to possibly as high as 80 degrees.
545 AM CST Mon Dec 4 2023 (Monday through Tuesday) Another cold front is moving across the area this morning and should exit to the southeast near or shortly after daybreak. I wouldn't be surprised to see a couple of overnight lows near or just below freezing in Southeast Oklahoma and adjacent portions of Southwest Arkansas. Yet another cold front should begin to move across the region around midday Tuesday. This should keep daytime high temperatures limited to the lower 60s across Southeast Oklahoma and much of Southwest Arkansas.
Low pressure will bring more widespread rain and snow to the region Tuesday and Tuesday night.
Due to the scale of the feature and the mixing involved, dew points will likely be even lower than many of the high res models are indicating.
West edge of low clouds naer the trough boundary as well within the west edge of the valley. As system departs tonight a north wind 5-10 kts takes over and should be enough to get rid of the low level moisture and bring clearing to many areas overnight into Tuesday. With more sun Tuesday and limited cooling behind the system did lean toward slightly warmer temps for highs on Tuesday.
With sfc temperatures near to above freezing, am not seeing much in the way of accumulations, probably less than an inch. At that time a ridge aloft builds strongly across the Rockies and into the Norther Plains. The initial upper flow pattern in this period will feature a significant upper ridge over the Plains and central CONUS during the mid-week time frame.
(Today through Tuesday) Surface obs, regional radar, and infrared satellite imagery show a cold front rapidly pushing southward early this morning into the Hill Country. Temperatures should dip into the 30s for most of the Hill Country and the lower to middle 40s for the rest of us.
5 inches across the area, even in advance of a reinforcing cold front pushing through at the surface today. With clear skies tonight and high pressure moving in behind the cold front to bring calmer winds, parts of the area have a good chance to see temps fall to near freezing Tuesday morning with frost. /NF/ By Tuesday, an upper trough is progged to exit the Lower Mississippi Valley and have brought a cold front through the ArkLaMiss region.
For early morning update, have advanced timing of the higher snow chances by an hour or two from previous forecast, and increased chances to likely down to the South Dakota border. Current surface analysis places low over southeast Saskatchewan, with cold front sweeping from central into eastern Montana. There may be a spot or two of a little bit of an attempt to transition to rain over parts of southwest North Dakota as some warmer air aloft tries to work into the system. Although the cold air advection in the wake of the cold front is quite modest at best, model soundings over far southwest North Dakota still show the potential for ~45kt winds mixing down, so will leave going wind advisory intact.
Highs today and Tuesday in the low to mid 70s with lows tonight from the mid 40s inland to the mid 50s along the coast.
