Aikyam-Lab/Synoptic-Bench huggingface dataset:
(Today and tonight) Upper trough near the four corners area early this morning will continue to push east today. As the upper low tracks east/northeast tonight, a strong cold front will enter northwest Oklahoma and will move through much of the area overnight. Strong, gusty north winds will develop behind the front with much cooler airmass surging south as well.
1246 AM EDT Mon Mar 21 2022 High pressure moves across the Mid-Atlantic early this week bringing continued dry weather along with warming temperatures. The upper trough slides off the coast this evening, with clouds dissipating and diminishing winds over the next few hrs. Then, mstly clr overnite as high pressure builds in from the W. Dry and very pleasant Monday as high pressure builds over the region. High pressure remains near the coast Monday night. Mostly clear with low temperatures in the lower to mid 40s.
(Today) Upper level low currently moving through AZ/NM will eject into the plains today.
309 AM CDT Mon Mar 21 2022 As expected a mild night in progress with widespread cirrus clouds and southeast to south winds, with early morning temperatures in the lower 50s. Being such a warm start to the day and the brute force of the warm advection, afternoon temperatures should be able to soar into the lower to mid 70s (despite the high cloudiness). However, these readings are no where near record highs which are in the lower to mid 80s.
435 AM EDT Mon Mar 21 2022 High pressure will provide dry weather and warmer temperature before rain chances increase during the midweek period with approaching low pressure. Dry conditions, well above normal temperature, and plenty of sunshine can be expected today with high pressure in control.
Valleys have cooled a bit quicker while the ridges have stayed a bit warmer than expected. Have overall adjusted the valleys down and the ridges up to produce a slightly larger ridge to valley split of 8-12 degrees. This has brought plenty of sunshine to the area along with warmer temps on mainly west winds of 5 to 10 mph with occasional gusts to around 15 mph. They all depict mid level ridging building strongly over Kentucky tonight into Monday in advance of a deep full latitude trough moving east out of the Four Corners Region.
132 AM EDT Mon Mar 21 2022 High pressure nearby today and tonight. Cooler and showery by the weekend. High pressure southeast of the area brings fair weather, with plenty of sunshine today, and then increasing high cloudiness tonight, ahead of the next weather system approaching from the west. After a chilly morning, central guidance reflects low level warm advection propelling temperatures above normal today, with ridges even warming a bit before dawn enhancing a ridge valley split. With lowland highs in the lower 70s, and dew points in the lower to mid 30s, RH values will bottom out in the mid 20s this afternoon.
345 AM EDT Mon Mar 21 2022 Beautiful day ahead for Eastern KY as high pressure over the TN valley drift off towards the SE US this afternoon and off the coast this evening. Afternoon high temps will be in the lower 70s. High clouds continue to move in overnight, although it won't be enough to prevent a bit of a ridge/valley split. Overnight lows will be in the lower 40s in the deeper valleys, to mid and upper 40s elsewhere.
210 AM MDT Mon Mar 21 2022 The trough will continue to move east early this morning pushing any lingering precipitation outside out CWA.
As upper level flow turns northwesterly, moisture is riding over a ridge along the West Coast and into the Northern Rockies this morning. There is not quite enough moisture or lift to produce widespread precipitation, so most of the action will be over the higher terrain where the topography can provide some lifting of the incoming moisture. Even there, accumulations today will be small and limited to the peaks of northwest Montana including the Cabinet, Mission, and Swan ranges, where six inches of snow will be the high end.
349 AM CDT Mon Mar 21 2022 Key Points: - Widespread rainfall over the next few days as a deep upper low moves over the area - Several rounds of rain, with the heaviest this evening and tonight The main focus this morning remains on the deep upper low currently over the Four Corners region. With heights falling as this trough lifts northeast, lee cyclogenesis is occurring across eastern New Mexico. The strongest height falls and PVA will occur this evening and tonight with the approach of the main upper low.
Moisture levels within the lower and middle portions of the atmosphere will slowly begin to increase late in the day but the warm temperatures in the near surface will limit any formation.
This evening, the upper low over northern TX will lift into OK/KS with widespread precip underway over the region.
1259 AM EDT Mon Mar 21 2022 High pressure will the area dry through Monday night. High pressure and a dry airmass will be in place across the region tonight. Surface ridging will persist across the area on Monday and get nudged eastward Monday night.
Short-range guidance appears to be slowing down the timing of the cold front later tonight so have tweaked things a bit with slower trends in terms of the mention of VCSH/VCTS.
Cold front currently situated from central ND, through central SD to northeast CO. Associated upper trough strengthens as it slides east into the Plains through today, with cold front projected to push into western MN/northwest IA by early this evening. This should result in steady to slowly falling temperatures through the afternoon, after reaching midday highs around 50 west to the upper 60s along the Highway 71 corridor in the far eastern CWA. As the upper low strengthens and begins to lift northeast through the Plains late tonight/tonight, we see a strong narrow zone of mid level frontogenesis develop from western Kansas, through central and eastern Nebraska, into far southeast South Dakota/northwest Iowa.
1115 PM EDT Sun Mar 20 2022 An upper level ridge over the Mississippi Valley will shift east toward Pennsylvania early this week.
410 AM EDT Mon Mar 21 2022 High pressure over the SE U. Cold front moves E of the state on Fri with improving conditions as a cooler/drier air mass sinks into the peninsula into the weekend as high pressure builds into the area. Clouds and rain chances increase from NW to SE late Wed into Thu limiting afternoon highs on Thu to the mid 70s/lower 80s, followed by even cooler highs in the 70s area wide in the wake of the front on Fri and continuing into the weekend. High pressure over the SE U.
The showers will develop as a result of moderate isentropic upglide and rather strong 850-700 mb frontogenetical forcing to the north of the warm front over far southern MI.
104 AM EDT Mon Mar 21 2022 High pressure will prevail for the next few days. A storm system will then impact the area mid week before high pressure likely returns by the end of the week.
305 AM EDT Mon Mar 21 2022 High pressure will keep the area dry through tonight. High pressure remains centered over southern CONUS today. Southwesterly winds and partly/mostly sunny skies persist across the Ohio Valley northwest of the high. High pressure starts drifting off the Southeast Coast tonight ahead on an approaching low pressure system and upper level trough.
348 AM EDT Mon Mar 21 2022 Low pressure will exit across the Maritimes through today.
237 AM MDT Mon Mar 21 2022 Upper trof moving through the northern plains today, will stall in the upper midwest through midweek. Upper ridge will dominate over the west.
1031 PM MDT Sun Mar 20 2022 Water vapor shows upper ridge over the Plains with elongated trof moving into the Rockies. At the surface, cold front is moving into northeast WY early this afternoon, with warm/dry/breezy conditions ahead of the front. Cold front will move into far western SD early this evening, then sweep through the rest of the forecast area this evening and overnight.
/Issued 309 PM CDT Sun Mar 20 2022/ An elongated trough from the northern Gulf of California to northwest Arizona will continue to move east and it will pinch off into a closed low over southwest/south-central New Mexico by sunrise on Monday.
1031 PM MDT Sun Mar 20 2022 Satellite trends show the northern stream of an overall trough across the eastern Idaho. Convergent flow from the surface cold front to 700mb should result in scattered to possibly numerous rain/snow showers. In wake of the trough axis, a dry northwest flow is expected Monday and Monday night. Northerly flow will prevail as a sharp ridge builds along the west coast.
309 AM EDT Mon Mar 21 2022 Beautiful day ahead for Eastern KY as high pressure over the TN valley drift off towards the SE US this afternoon and off the coast this evening. Afternoon high temps will be in the lower 70s. High clouds continue to move in overnight, although it won't be enough to prevent a bit of a ridge/valley split. Overnight lows will be in the lower 40s in the deeper valleys, to mid and upper 40s elsewhere.
Temperatures varied across the region with the cooler valley and rural locations in the mid- upper 30s. On the ridges, temperatures were in the lower-mid 40s. Temperatures should be a bit warmer today with mid-level ridging and warmer mid-level temps overspreading the area. Highs should top out in the upper 60s to the lower 70s.
154 AM EDT Mon Mar 21 2022 High pressure moves across the Mid-Atlantic region early this week bringing dry weather along with warming temperatures. Dry and very pleasant Monday as high pressure builds over the region. High pressure remains near the coast Monday night. Mostly clear with low temperatures in the lower to mid 40s.
347 AM EDT Mon Mar 21 2022 High pressure over the southern Appalachains this morning will move off the East Coast by tonight.
1235 AM EDT Mon Mar 21 2022 An upper level ridge over the Mississippi Valley will shift east toward Pennsylvania early this week.
726 AM EDT Mon Mar 21 2022 High pressure will provide dry weather and warmer temperature before rain chances increase during the midweek period with approaching low pressure. A deepening trough over the central CONUS will bring a modest moisture increase on Tuesday. The day should remain mostly dry, but increased cloud coverage will keep daytime highs slightly cooler than today.
604 AM EDT Mon Mar 21 2022 A weak and dry cold front will drift south across the Commonwealth this afternoon and evening. An upper level ridge over the Mississippi Valley will shift east toward Pennsylvania early this week.
Strong, gusty winds out of the north remain Monday with cool temperatures following the cold front passage.
/issued 450 AM CDT Mon Mar 21 2022/ Early morning GOES water vapor imagery showed a deepening upper low lifting east into western NM. Downstream, diffluent flow aloft was evident over the southern plains, and ridging further downstream over the lower MS River valley. The upper low will lift into southern high plains by this evening, with diffluent flow aloft and tightening low level pressure gradient spreading into the Midsouth. With impressive kinematics a near sure bet, severe weather chances will ride almost entirely on how far north the low level instability axis can build into north MS. By Tuesday evening, a midlevel dry slot will wrap into the Midsouth, as the upper low lifts into the mid-MS River valley.
915 AM CDT Mon Mar 21 2022 (Issued 915 AM CDT Mon Mar 21 2022) A warm front is progged to stall across central/southern Wisconsin this afternoon. Will need to keep an eye on how dew points and temperatures behave south of the warm front day. Latest RAP guidance hints at the potential for RHs to fall lower than forecast, if the low-level inversion can mix out this afternoon. Anderson (Issued 408 AM CDT Mon Mar 21 2022) Today through Tuesday: Low pressure currently over eastern SD will weaken as it tracks into southern WI tonight. A warm frontal boundary will sharpen over central WI as the low approaches. This front is expected to end up a little farther south than the forecast suggested yesterday, so cooler temps can be expected toward east central WI, enhanced by cold air off the lake.
517 AM MDT Mon Mar 21 2022 08z surface analysis had low over eastern SD with cold front into northeast CO, almost through KICR. Water vapour loop showed upper trough from southern SK to AZ/NM. Main energy at bottom of trough. Evolution of upper trough still main weather maker this week. Today/tonight, -SN ends this morning as drier air pushes into the CWA and synoptic forcing associated with upper trough moves northeast.
1035 AM EDT Mon Mar 21 2022 High pressure will keep the area dry through tonight. High pressure centered over the southern Appalachians will keep south to southwesterly flow across the region. High pressure starts drifting off the Southeast Coast tonight ahead on an approaching low pressure system and upper level trough. Highly amplified mid level flow with a long wave trof tracking slowly from Plains into the Great Lakes by the end of the week.
A spring weather system will maintain gusty winds and cooler temperatures through today.
This low should continue to move east along with an attendant cold front into MN later this morning. More lift/moisture from the southern stream upper low will bring post- frontal rain/snow to the far eastern CWA later today and tonight, potentially lingering into Tuesday.
High pressure continues to build into the region throughout the week, providing warm and dry conditions.
Most will be lucky to receive more than a hundredth or two of qpf along and west of the Highway 83 corridor. Presently, a narrow corridor of very gusty winds is occurring as well with initial pressure rises behind the passing trough. Winds have shifted to the northwest and have become breezy on the backside of the trough. To start the period, a west CONUS ridge will amplify as upper low pressure over the southern Plains gradually churns to the northeast.
1040 AM EDT Mon Mar 21 2022 High pressure builds in today, then a weak cold front moves through tonight.
Marine platforms along the reef with winds slightly more elevated across our eastern waters, resulting in a swath of speed convergence across the Hawk Channel and Straits of Florida, with the highest concentration in our western waters. Temperatures have slowly started climbing, however with a blanket of partly cloudy skies, temperatures are only expected to get into the lower 70s this afternoon. A strong high pressure building off of the Carolina coast has allowed northeast to east breezes to become fresh to strong.
600 AM EDT Mon Mar 21 2022 Low pressure will exit across the Maritimes through today.
513 AM EDT Mon Mar 21 2022 A weak and dry cold front will drift south across the Commonwealth this afternoon and evening. An upper level ridge over the Mississippi Valley will shift east toward Pennsylvania early this week.

as a pair of upper-level troughs pivot across the Rockies this morning. The surface pressure gradient will continue to tighten today in between departing high pressure and developing low pressure over the Plains. Model soundings suggest that the troposphere will become saturated from the top-down as parcels overrun a surface warm front that'll be displaced well south of the region. Overnight lows will hold steadily in the lower 50s.
635 AM EDT Mon Mar 21 2022 High pressure over the southern Appalachains this morning will move off the East Coast by tonight.
Beautiful day ahead for Eastern KY as high pressure over the TN valley drift off towards the SE US this afternoon and off the coast this evening. Afternoon high temps will be in the lower 70s. High clouds continue to move in overnight, although it won't be enough to prevent a bit of a ridge/valley split. Overnight lows will be in the lower 40s in the deeper valleys, to mid and upper 40s elsewhere. On Tuesday a surface and upper level low will move from the southwest states into the middle of the country during the day. Starting off, a deep trough will dominate much of the Central CONUS, with northern stream influence largely cut-off as a stacked low sits across the Mid Mississippi Valley.
618 AM EDT Mon Mar 21 2022 High pressure will keep the area dry through tonight. High pressure remains centered over southern CONUS today. Southwesterly winds and partly/mostly sunny skies persist across the Ohio Valley northwest of the high. High pressure starts drifting off the Southeast Coast tonight ahead on an approaching low pressure system and upper level trough. Highly amplified mid level flow with a long wave trof tracking slowly from Plains into the Great Lakes by the end of the week.
408 AM CDT Mon Mar 21 2022 (Issued 408 AM CDT Mon Mar 21 2022) Today through Tuesday: Low pressure currently over eastern SD will weaken as it tracks into southern WI tonight. A warm frontal boundary will sharpen over central WI as the low approaches. This front is expected to end up a little farther south than the forecast suggested yesterday, so cooler temps can be expected toward east central WI, enhanced by cold air off the lake.
634 AM EDT Mon Mar 21 2022 High pressure moves across the Mid-Atlantic region early this week bringing dry weather along with warming temperatures. There is a weak backdoor boundary that tries to drop into the Lower MD Eastern Shore in the afternoon. Increasing clouds and milder Tues night as hi pres shifts farther E away from the coast lo pres and a warm front approach from the SW. primarily from W-E INVOF of the warm front.
Presently, a narrow corridor of very gusty winds is occurring as well with initial pressure rises behind the passing trough. Winds have shifted to the northwest and have become breezy on the backside of the trough. To start the period, a west CONUS ridge will amplify as upper low pressure over the southern Plains gradually churns to the northeast.
626 AM CDT Mon Mar 21 2022 (Today and tonight) Upper trough near the four corners area early this morning will continue to push east today. As the upper low tracks east/northeast tonight, a strong cold front will enter northwest Oklahoma and will move through much of the area overnight. Strong, gusty north winds will develop behind the front with much cooler airmass surging south as well.
Upper ridge continues to build today, but will already be breaking down tonight. In addition to a deep closed upper low, this system also has a deep SFC/LL which will pass west/north of the mid-state Tues night/Wed. This system is so dynamic that the southern stream will either spin up another closed low or just deepen the ML/LL trough once again Thu/Thu night, and bring a secondary front across the area Thu afternoon. Our upper trough however not done just yet.
High pressure will become established through the remainder of the week, bringing dry conditions along with a warming trend.
627 AM CDT Mon Mar 21 2022 (Today) Upper level low currently moving through AZ/NM will eject into the plains today.
Gusty north winds will linger Tuesday along the Colorado River Valley then a strong ridge builds over the western states providing tranquil weather and well above average temperatures by the weekend. Temperatures will be near normal today with highs in the lower 70s in Vegas and will climb 5 or so degrees Tuesday.
Key Points: - Widespread rainfall over the next few days as a deep upper low moves over the area - Several rounds of rain, with the heaviest this evening and tonight The main focus this morning remains on the deep upper low currently over the Four Corners region. With heights falling as this trough lifts northeast, lee cyclogenesis is occurring across eastern New Mexico. The strongest height falls and PVA will occur this evening and tonight with the approach of the main upper low. The initial area of rain will move off to the northeast, with a secondary band of precipitation over central Kansas behind the low. On the east side of the low, across east-central Kansas, there could be a brief break in the precipitation as the dry slot works in.
1001 AM EDT Mon Mar 21 2022 High pressure will shift to the NC coast this evening.
924 AM EDT Mon Mar 21 2022 High pressure moves across the Mid-Atlantic region early this week bringing dry weather along with warming temperatures. There is a weak backdoor boundary that tries to drop into the Lower MD Eastern Shore in the afternoon. Increasing clouds and milder Tues night as hi pres shifts farther E away from the coast lo pres and a warm front approach from the SW. primarily from W-E INVOF of the warm front.
An upper trough currently sits over the region with split flow to our west. With the northern split, an upper trough moves into the western part of the Dakotas today. A closed, upper low will move across New Mexico and Texas through the day, before lifting to the northeast across Central and Eastern Kansas overnight. Temperatures for this afternoon were raised slightly due to an expected delay in the arrival of a cold front and consequently warming resultant from southerly winds. With windy conditions expected and minimum relative humidity values falling into the low to mid-20s in the northwestern portion of the area, near-critical fire weather conditions are expected.
As expected a mild night in progress with widespread cirrus clouds and southeast to south winds, with early morning temperatures in the lower 50s. Being such a warm start to the day and the brute force of the warm advection, afternoon temperatures should be able to soar into the lower to mid 70s (despite the high cloudiness). However, these readings are no where near record highs which are in the lower to mid 80s.
Strong southerly flow out ahead of the trough will allow for moisture to shoot northward into central Kansas. Tuesday will be cooler with lingering rain as the system progresses eastward, should see rain clear out from west to east during the afternoon.
A weather system was moving through a ridge of high pressure and into our region this morning spreading showers across the area. A challenge is how much of the pcpn will develop with the ridge in place and the latest radar was showing the showers progressing and expanding in coverage with rain being reported at a number of locations including snow in meh. As the weather system moves away the high pressure ridge re-establishes across our area on Tuesday with mostly drier conditions and warmer temperatures expected with afternoon highs climbing into the 60s across portions of the area.
305 AM MDT Mon Mar 21 2022 Trough axis currently divides the state, with light snow continuing across central WY. The trough will continue to drift east today,switching winds aloft more from the northwest. Northerly flow will continue into Tuesday as the trough only slowly drift across the central US. Models are picking up on a vort max sweeping southward across eastern WY off the backside of the trough. Most of the period will feature upper-level ridging and pleasant spring weather.
607 AM EDT Mon Mar 21 2022 High pressure moves across the Mid-Atlantic region early this week bringing dry weather along with warming temperatures. There is a weak backdoor boundary that tries to drop into the Lower MD Eastern Shore in the afternoon. Increasing clouds and milder Tues night as hi pres shifts farther E away from the coast lo pres and a warm front approach from the SW. primarily from W-E INVOF of the warm front.
425 AM PDT Mon Mar 21 2022 High pressure aloft and offshore flow will bring much warmer weather through the middle of the weak with gusty northeast winds near the coastal slopes of the mountains.
