Aikyam-Lab/Synoptic-Bench huggingface dataset:
Dry conditions and warmer temperatures are expected through the middle of the week. Another storm system will impact the area mid to late in the week with cooler temperatures and a chance of showers.
Temperatures along the Island Chain are currently in the lower to mid 70s with dew points in the lower to mid 60s.
The precip will transition to showers on Tuesday as instability arrives with an upper trough.
Passing cirrus continues to stream overhead, as high pressure persists over the area. Forecast lows in the lower 50s, with mid-50s along the coast and upper 40s across northern Lake and Volusia Counties.
While most of the area will see light snow, some of the higher terrain could see over 6 inches of fresh snowfall over the course of this system and brief periods of heavy snow will also be possible at lower elevations. Northwesterly flow aloft associated with an approaching upper level trough will begin to push into Southwestern Montana on Tuesday, bringing some snow and valley rain to areas mostly south of I-90. While most areas will only see a light coating of snowfall with this system (generally under 2â), some of the higher terrain in the Madison and Gallatin County Mountains will see accumulations pushing 8 to 10 inches between Tuesday and Wednesday, which prompted the issuance of a Winter Storm Warning from the previous shift.
(Today through Wednesday) Weak ridging will persist through this evening, bringing Pacific moisture into the area.
(Today through Wednesday) A large area of high pressure is in place across the area, with generally just some passing cirrus for the next two days along with dry conditions. By Wednesday, the high will be more centered over the Mid-Atlantic and we will have more of a southerly flow and begin to moisten up a touch aloft, at least in the west. Overnight tonight, most areas will be in the low 40s, with only the northeast in the upper 30s. A few of our locally cooler locations may still get into the mid 30s, but we should only see isolated frost potential in these areas, so will fore-go any additional advisories at this time.
This ridge shifts east into the Upper Great Lakes through tonight. Mixing has also brought down the drier air mass aloft, bringing dewpoints into the low to mid 20s save for near Lake Michigan/eastern U. Tuesday night, an associated cold front will sweep across Upper Michigan, but will continue toward a dry forecast without any precipitation chances in the CAMs. The dry weather will persist through Wednesday, too, but temperatures will be a bit cooler in the wake of the cold front (still well above normal though).
1200 AM EDT Tue Mar 12 2024 - Warming trend through the early week period, peaking in the low to mid 60s Tuesday and Wednesday.
354 AM EDT Tue Mar 12 2024 High pressure over the region will give way to a developing warm front on Wednesday.
A cutoff low pressure system will impact Arizona Wednesday into the weekend. Quiet evening across the state as winds have dropped off and skies are starting to clear out as a trough pushes off to the east. For tomorrow, another trough will start to approach the region. Looks like we keep mostly zonal, westerly flow across our area with the trough crossing just to the north. With this in mind, made some slight adjustments to the PoPs for Tuesday night as the higher res guidance is not as progressive with the precipitation. Renewed southwest flow ahead of an incoming longwave trough will bring another round of breezy, dry, and mild weather tomorrow. Noticeable changes will occur in the subsequent days as the trough rapidly deepens, sending the core of its upper level low pressure area into the Desert Southwest.
Ridging aloft builds over the E U. on Thu-Fri allowing temps locally to climb to above normal and potentially near-record values on Fri-Sun as surface ridging remains over the area south of a frontal boundary stalling to our north during the weekend. Ridging aloft weakens and gradually shifts E into the Atlantic over the weekend in response to an amplifying C U. trough, which then swings E across the E U. High pressure remains over the region with no headlines expected through the end of the work week.
410 AM EDT Tue Mar 12 2024 High pressure remains in control through most of the week bringing warm and dry conditions.
114 AM EDT Tue Mar 12 2024 Expect a warming trend through the week as high pressure shifts offshore.
The clouds along with a persistent west-southwest breeze has propped up temps holding in the low 40s while decoupled locations have dropped as low as the mid 30s. Expect the lower clouds to fade this morning giving way to plenty of sunshine. The big story today will be the noticeable warm up with 24hr max delta Ts on the order of +10-20F warmer vs.
246 AM CDT Tue Mar 12 2024 - 'Cooler' for Today and Wednesday, though highs are still some 15- 25 degrees above normal today and 10-20 degrees above for Wednesday.
(Today and tonight) High pressure at the surface and aloft will continue to control the weather in the short term, with fair and dry weather today and tonight. But this will all combine to make today a good 6 to 8 degrees warmer than yesterday. The warmer temps will help drop minimum RHs this afternoon to near 20% in places.
235 AM EDT Tue Mar 12 2024 High pressure brings sunshine and moderating temperatures through Wednesday. A high pressure system will provide dry weather today and tonight.
With high pressure over the area, will have another cool night, with low temperatures in the upper 30s to lower 40s across the area, except mid 40s coast and our southernmost counties in NE FL. (Tuesday through Wednesday night) Another day of dry and cool weather as high pressure remains over the area on Tuesday. Light winds from the south- southwest will see warmer air will trickle in, leading to warmer daytime highs from the mid to upper 70s for the area. Cooler temperatures along the coast as the seabreeze will allow for cool maritime air to move in. The rest of NE FL will see lows in the lower 50s. By the overnight hours, lows in the lower 50s over SE GA and the the mid to upper 50s for NE FL.
106 AM EDT Tue Mar 12 2024 Low pressure over the Canadian Maritimes departs tonight. High pressure over the Tennessee Valley builds eastward through Tuesday, and moves offshore by Wednesday.

1253 AM EDT Tue Mar 12 2024 High pressure brings sunshine and moderating temperatures through Wednesday. A high pressure system will provide dry weather today and tonight.
(Today through Wednesday) High pressure over the eastern seaboard will shift east into the Atlantic on Tuesday resulting in the low-lvl flow veering more easterly. Overnight lows tonight will generally be in the low to mid 60s. Otherwise slightly warmer temperatures can be expected relative to Tuesday with generally SErly winds prevailing.
132 AM EDT Tue Mar 12 2024 High pressure will allow for dry conditions through Tuesday night with rain chances starting to return mid week.
High pressure will push off the east coast throughout the day today, increasing our southerly return flow. As a result, our warming trend will continue this afternoon with high temperatures peaking in the high 60s and low 70s.
254 AM MDT Tue Mar 12 2024 Mountain snow showers will continue through Wednesday as a Pacific low pressure system passes. Snow levels will fall down around 2,000 feet tonight into Wednesday morning as a cold front passes.
357 AM EDT Tue Mar 12 2024 High pressure will provide dry weather through midweek, with a return of well above-normal temperatures.
143 AM EDT Tue Mar 12 2024 High pressure will build over and offshore the Southeast through midweek.
Expect the low clouds to eventually affect most of the area south of Interstate 20 this morning, before scattering out during the afternoon, with some areas along I-10 possibly not clearing out until mid to late afternoon. Would even go warmer with highs if it weren't for the expected cloud cover through the morning hours.
332 AM EDT Tue Mar 12 2024 High pressure over the Tennessee Valley builds eastward through Tuesday, and moves offshore by Wednesday.

1238 AM EDT Tue Mar 12 2024 High pressure will provide dry weather through midweek, with a return of well above-normal temperatures.
The warming trend will continue with inland temperatures in the lower to mid 80s today, while beach temps remain anchored in the mid 70s. Light southeast winds on Tuesday may become moderate to even breezy on Wednesday as Gulf of Mexico high pressure interacts with Southern Plains lower pressure. A weak short wave trough will move over the Upper Valley and RGV Plains Tuesday night.
1231 AM CDT Tue Mar 12 2024 - Cooler for Tuesday with highs 15-25 degrees above normal.
111 AM EDT Tue Mar 12 2024 High pressure will build into our region today, prevailing for most of the week.

CIMSS mean steering layer for 250 to 850 mb notes a zonal westerly flow over the state of Florida after deep layer ridging in the Caribbean shifted southeast. From synopsis, high pressure over the southeastern United States will drive east southeastwards into the Atlantic over the next couple of days. This high will meander northeast of the Bahamas through the remainder of the week, generally keeping gentle to moderate east to southeasterly breezes. The highs trade wind belt will lift northward through the back half of the week resulting in modestly freshening breezes.
1032 AM EDT Tue Mar 12 2024 High pressure over the Tennessee Valley builds eastward today, and moves offshore by Wednesday.
634 AM EDT Tue Mar 12 2024 Expect a warming trend through the week as high pressure shifts offshore.
(Now through Wednesday) Temperatures have settled into the upper 30s to low 40s across much of the area (slightly warmer at the beaches) as of 9z this morning. The high doesn't stick around for long as it treks into the western Atlantic by Wednesday. Onshore flow in the lower levels quickly becomes established later this afternoon and into this evening on the western periphery of the high. Dewpoints will likely still have an opportunity to plunge into the low 30s by early this afternoon, especially across the eastern half of the area, before the moisture levels begin to creep up. Most of the area should top out in the low 70s this afternoon and soar into the mid to upper 70s by Wednesday afternoon (slightly cooler at the beaches).
625 AM EDT Tue Mar 12 2024 High pressure over the region will give way to a developing warm front on Wednesday.
The clouds along with a persistent west-southwest breeze propped up temps in most locations holding in the lower 40s while a few decoupled valley locations dropped into the lower 30s. The big story today will be the noticeable warm up with 24hr max delta Ts on the order of +10-20F warmer vs.
A cutoff low pressure system will impact Arizona from Wednesday and into the weekend. This low has not even formed yet and we do not know the extent that it will retrograde once it does. 00Z ECMWF runs really amplify the Pacific Northwest ridge later in the week, which then traps the low in a blocking position. The ECMWF now has the low over Arizona through next Tuesday, a curious development. Ahead of the low, a cold front and Pacific moisture will affect northern Arizona Tuesday night and Wednesday, with a frontal boundary dropping to the I-40 corridor before stalling out.
As an upper trough moves onshore this morning, current satellite imagery shows mid-level and high clouds filtering into Idaho through the upper-level southwesterly flow. With widespread overnight temperatures still in the upper 30s across the lower elevations, snow levels are generally above 5,000 feet areawide. A cold front will shift eastward through the region this afternoon, with hi-res models continuing to show convective enhancement associated with the frontal passage. Of greater impact could be a potential Snake Plain convergence setup, with strong signatures on hi-res models for surface winds to converge Wednesday afternoon as a closed low develops over Idaho and drops south into Nevada/Utah.
729 AM EDT Tue Mar 12 2024 (Today through Wednesday) High pressure over the eastern seaboard will shift east into the Atlantic on Tuesday resulting in the low-lvl flow veering more easterly. Overnight lows tonight will generally be in the low to mid 60s. Otherwise slightly warmer temperatures can be expected relative to Tuesday with generally SErly winds prevailing.
746 AM EDT Tue Mar 12 2024 High pressure brings sunshine and moderating temperatures through Wednesday. A high pressure system will provide dry weather today and tonight.
629 AM EDT Tue Mar 12 2024 High pressure over the Tennessee Valley builds eastward through Tuesday, and moves offshore by Wednesday.
(Rest of Today) With high pressure sitting overhead, expect another beautiful early Spring day with ample sunshine. The only concern today will be very dry conditions as dewpoints will hover in the low to mid 30s, bringing RH values into the low 20 percents this afternoon.
605 AM CDT Tue Mar 12 2024 (Today through Wednesday) Weak ridging will persist through this evening, bringing Pacific moisture into the area.

330 PM EDT Tue Mar 12 2024 High pressure remains in control through most of the week bringing warm and dry conditions.
An upper level ridge will continue to build over of the Eastern US helping to increase temperatures into the weekend.
300 PM EDT Tue Mar 12 2024 A warm front moves through Wednesday, bringing even warmer conditions. Conditions will slowly trend cooler through the second half of the week with a couple rounds of rain showers also expected. Quiet conditions continue through the near term period as high pressure remains in control. Overnight, moisture increases as a warm front begins to move through the region, so skies become at least partly cloudy. Tomorrow night will be slightly warmer for some as temperatures will range form the upper 30s to mid 40s.
140 PM EDT Tue Mar 12 2024 High pressure will continue to linger offshore the Southeast through midweek.
Meteorological Details: A mid-level trough with a speed max is forecast to lift into the Southern Plains with strengthening surface cyclogenesis in southwest Kansas. In response, the low- level thermal ridge (LLTR) across west Texas today will advance eastward with a sharpening dryline into western Oklahoma and western north Texas.
118 PM EDT Tue Mar 12 2024 (Today and tonight) High pressure at the surface and aloft will continue to control the weather in the short term, with fair and dry weather today and tonight. But this will all combine to make today a good 6 to 8 degrees warmer than yesterday. The warmer temps will help drop minimum RHs this afternoon to near 20% in places.
(This evening through Wednesday) The temporary mid/upper level ridge in place will move off to the east tonight ahead of a potent upper low situated in the desert southwest causing 1000-500 mb thicknesses to drop gradually. A weakening cold front will bring a northerly wind shift to the northern portions of our CWA tonight, however, westerly surface winds will recover by tomorrow morning. Adding to the low RH values and ample dry fuels already in place, critical fire conditions are expected for the entire forecasting area.
1217 PM CDT Tue Mar 12 2024 - 'Cooler' for Today and Wednesday, though highs are still some 15- 25 degrees above normal today and 10-20 degrees above for Wednesday.
1246 PM EDT Tue Mar 12 2024 High pressure over the region will give way to a developing warm front on Wednesday.
For most of the region (excluding the higher elevations in north Georgia) this should translate into highs in the mid 70s. Tonight's low temperatures should be in the lower 40s, while mid to upper 40s are anticipated Wednesday night.
1211 PM EDT Tue Mar 12 2024 Today and Wednesday high pressure over the southeast United States will keep the weather dry over our region.
224 PM EDT Tue Mar 12 2024 High pressure will linger off the Southeast coast through midweek.
Light rain showers this morning will give way to a prolonged dry period across the region as high pressure builds across the eastern Pacific.
1123 AM CDT Tue Mar 12 2024 (Rest of Today) With high pressure sitting overhead, expect another beautiful early Spring day with ample sunshine. The only concern today will be very dry conditions as dewpoints will hover in the low to mid 30s, bringing RH values into the low 20 percents this afternoon.
352 PM EDT Tue Mar 12 2024 A warm front moves through Wednesday, bringing even warmer conditions. Conditions will slowly trend cooler through the second half of the week with a couple rounds of rain showers also expected. Quiet conditions continue through the near term period as high pressure remains in control. Overnight, moisture increases as a warm front begins to move through the region, so skies become at least partly cloudy. Tomorrow night will be slightly warmer for some as temperatures will range form the upper 30s to mid 40s.
These clouds are steered by high pressure sitting just off the southeast coast of CONUS. This high also continues to promote gentle to moderate easterly breezes along our Reef observation stations. The previously mentioned high pressure will continue to meander east into the western North Atlantic into tonight. Above average temperatures will remain in the forecast into this weekend as deep layer ridging establishes itself along the Eastern Seaboard.
Tonight into Wednesday expect light winds and quiet weather to prevail ahead of the next cold front.
Satellite and radar imagery showing the upper trough axis in central Oregon this morning, with a leading area of precipitation pushing into SW Idaho. As the trough moves overhead, daytime heating and cooling aloft will feed widespread shower and isolated thunderstorm development.
128 PM EDT Tue Mar 12 2024 High pressure over the Tennessee Valley builds eastward today, and moves offshore by Wednesday.
Temperatures are expected to warm into the lower 70s later today.
144 PM EDT Tue Mar 12 2024 High pressure brings sunshine and moderating temperatures through Wednesday. Quiet weather in the near term period with high pressure in control. High clouds will cross the area late tonight and early Wednesday from a weak passing disturbance, along with another ridge/valley temperature split expected overnight. Wednesday looks to be continued dry, and slightly warmer with upper heights building across the area out ahead of approaching system. An area of low pressure will build over the Midwest.
The lower dew point values are pushing relative humidity values into the mid 20th percentile, and it will remain dry through the afternoon/evening hours. Mostly clear skies and dry atmosphere will help drop temperatures down into the upper 30s or lower 40s overnight, but this is several degrees warmer than last night and widespread frost looks much less likely overnight. Quiet weather will continue into tomorrow with daytime highs expected to be about 5 degrees warmer than today.
The high doesn't stick around for long as it treks into the western Atlantic by Wednesday. Onshore flow in the lower levels quickly becomes established later this afternoon and into this evening on the western periphery of the high. Dewpoints will likely still have an opportunity to plunge into the low 30s by early this afternoon, especially across the eastern half of the area, before the moisture levels begin to creep up. Most of the area should top out in the low 70s this afternoon and soar into the mid to upper 70s by Wednesday afternoon (slightly cooler at the beaches).
This is due to ridging across the southeastern US that will slowly shift eastward, allowing for some prolonged southerly flow in the process. Overnight into tomorrow morning, that southerly flow will boost the moisture in the atmosphere enough for some increased fog potential across Deep East Texas/Central Louisiana, moderating temperature minimums into the lower 60s tonight and upper 60s tomorrow night.
125 PM EDT Tue Mar 12 2024 Expect a warming trend through the week as high pressure shifts offshore.
An upper trough will begin to take shape across the Desert Southwest Wednesday as a Rex blocking pattern sets up. The 850 mb thermal ridge will continue to build across the area tomorrow with temperatures increasing 3-4 deg C from where they are today.
The Northern Rockies is currently in the center of a low pressure trough which is allowing for unstable conditions this afternoon.
Temperatures and snow levels will drop overnight to valley floors tonight as a trough sinks across eastern Idaho with a closed upper-low developing during the day Wednesday.
