Aikyam-Lab/Synoptic-Bench huggingface dataset:
(Tonight through Wednesday night) Low level flow across South Central Texas is from the south to southeast bringing a warmer, moister airmass to the region. Temperatures this afternoon are three to seven degrees warmer and dewpoints are 10 to 18 degrees higher than 24 hours ago. Temperatures will be warmer with lows from the upper 50s to middle 60s. The low level flow will continue to be from the southeast and temperatures will continue to warm.
117 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.
113 PM EDT Tue Mar 12 2024 High pressure over the region will give way to a developing warm front on Wednesday.
Southerly warm and breezy conditions, and 850 mb temperatures in the mid teens will lead to a warm day with highs mainly in the low 80s.
131 PM EDT Tue Mar 12 2024 Through Wednesday, high pressure over the southeast United States will keep the weather dry over our region.
335 PM EDT Tue Mar 12 2024 Temperatures will warm well above normal late this week as high pressure shifts offshore.
Neutral advection means we won't get too much warmer than Tuesday.
927 PM EDT Tue Mar 12 2024 A warm front will move through the area on Wednesday, with a continuing warming trend.
A weakening cold front has pushed into Southern California, ending our last chance for rain for quite some time. Tonight, skies begin to clear as high pressure builds over the EPac with a deep upper low digging into the Great Basin/Mountain West, which will promote a drying trend through the next few days.
707 PM EDT Tue Mar 12 2024 Temperatures will warm well above normal late this week as high pressure shifts offshore.
Still some gusts over 20 KTS in the higher elevations. Neutral advection means we won't get too much warmer than Tuesday.
436 PM PDT Tue Mar 12 2024 A weakening cold front has pushed into Southern California, ending our last chance for rain for quite some time. Tonight, skies begin to clear as high pressure builds over the EPac with a deep upper low digging into the Great Basin/Mountain West, which will promote a drying trend through the next few days.
(Now through Wednesday) Dry conditions are expected through the period as a large ridge of high pressure over the western Atlantic maintains its hold over the southeast US. Upper level flow will turn southwest as a large trough develops across the western states and slides east, allowing even deeper layer moisture to move into the region through the period.
723 PM EDT Tue Mar 12 2024 High pressure remains in control through most of the week bringing warm and dry conditions.
730 PM EDT Tue Mar 12 2024 High pressure will linger off the Southeast coast through midweek.
High pressure persists over the local area, with mostly clear skies overnight.
Still some gusts over 20 KTS in the higher elevations. Neutral advection means we won't get too much warmer than Tuesday afternoon.
941 PM EDT Tue Mar 12 2024 High pressure over the Tennessee Valley builds eastward today, and moves offshore by Wednesday.
636 PM CDT Tue Mar 12 2024 (Tonight through Wednesday night) Low level flow across South Central Texas is from the south to southeast bringing a warmer, moister airmass to the region. Temperatures this afternoon are three to seven degrees warmer and dewpoints are 10 to 18 degrees higher than 24 hours ago. Temperatures will be warmer with lows from the upper 50s to middle 60s. The low level flow will continue to be from the southeast and temperatures will continue to warm.
613 PM CDT Tue Mar 12 2024 (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.
738 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.
633 PM EDT Tue Mar 12 2024 High pressure over the Tennessee Valley builds eastward today, and moves offshore by Wednesday.
Expecting a tranquil night under scattered to broken cirrus, with lows several degrees "warmer" than last night -- in the upper-30s to 40s. 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.
This high has shifted slightly east over the few hours, which has allowed for the gradient to relax across the region. Temperatures along the island chain generally remain in the lower to mid 70s, with dew points in the lower to mid 60s. Due to lower confidence, have kept lows in the lower to mid 70s. From synopsis, high pressure over the southeastern United States will drive east southeastward 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 high's trade wind belt will lift northward through the back half of the week resulting in modestly freshening breezes.
High pressure dome in control of the region is providing a tranquil early evening across SoFlo, with prevailing benign weather conditions and a moderate SE flow turning light overnight. Lows tonight will again be in the low-mid 60s inland, and upper 60s near the coasts.
307 AM EDT Wed Mar 13 2024 A warm front moving northward the region will sag southward and stall over the region through Thursday night.
Still some gusts over 20 KTS in the higher elevations.
1248 AM CDT Wed Mar 13 2024 (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.
358 AM CDT Wed Mar 13 2024 - There is a 20 percent chance for a light freezing rain leading to a light glaze of ice in the Devils Lake Basin and northern Red River Valley near the US/Canada border late tonight into Wednesday morning.
337 AM EDT Wed Mar 13 2024 Temperatures will warm well above normal late this week as high pressure shifts offshore.
No wholesale modifications to the existing forecast package were necessary, save for incorporating the latest CONSShort data to nudge tonight's lows by a margin of a degree or two, still looking to range from the upper 50s north and east to the lower 60s west, and ingesting the last several hours worth of temperature and dewpoint obs and interpolating through the 13Z hour. 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.
348 AM EDT Wed Mar 13 2024 High pressure remains in control today.
1241 AM EDT Wed Mar 13 2024 (Wednesday through Thursday night) High pressure over the area will keep most of the Gulf moisture mainly to the south of north central Florida on Wednesday, setting up another day of dry and warm weather. Daytime highs in the upper 70s from the Suwanee Valley region into SE GA, while highs in the lower 80s from north central Florida up into the JAX metro area. Cooler temperatures along the coast as a seabreeze will keep coastal locations in the lower 70s. The high pressure will start its shift towards the Atlantic coast on Thursday, leading to a switch of overall flow to be southeasterly. Daytime Highs in the lower to mid 80s for inland locations, while coastal locations will be in the lower 70s.
1257 AM EDT Wed Mar 13 2024 High pressure remains in control today.
(Today through Thursday) A short wave trough is sitting just to our northwest early this morning and will push east thru the morning hours. Skies will become mostly clear as the afternoon goes on and we will warm nicely into the low to mid 70s. Quiet and mild weather can be expected into Wednesday night with short wave ridging. As we head into Thursday a closed off upper level low will develop over the four corners region and we will see short waves spin off of this into the Plains. This will push a cold front into Middle TN and will bring widespread rain and thunderstorms. CAPE ahead of this front will range from 250-650 j/kg with the highest CAPE expected west of I-65. This will be plenty of shear to see a few isolated organized thunderstorms in the higher CAPE areas.
353 AM EDT Wed Mar 13 2024 A warm front moving northward the region will sag southward and stall over the region through Thursday night.
412 AM EDT Wed Mar 13 2024 High pressure and dry conditions will continue across the region today and tomorrow.

1233 AM CDT Wed Mar 13 2024 (Tonight through Wednesday night) Low level flow across South Central Texas is from the south to southeast bringing a warmer, moister airmass to the region. Temperatures this afternoon are three to seven degrees warmer and dewpoints are 10 to 18 degrees higher than 24 hours ago. Temperatures will be warmer with lows from the upper 50s to middle 60s. The low level flow will continue to be from the southeast and temperatures will continue to warm.
1110 PM MDT Tue Mar 12 2024 1254 PM MDT Tue Mar 12 2024 - Splitting upper trof brings precipitation as well as cooler and windy weather for Wednesday and Thursday - Some snow accumulation expected in the Black Hills and higher elevations of northeast Wyoming - Modified arctic front moves into the Northern Plains/Upper Midwest over the weekend with a glancing blow to our area Water vapor shows upper trof digging through the northwestern CONUS. Upper trof will continue to dig across the western CONUS tonight while splitting. Main upper low will gradually form over the Desert Southwest Wednesday and stall out for several days, while the northern stream trof works slowly through the Northern Plains late week.
Discussion: A weak wave will try to move into the Ohio and Tennessee valley today but persistent ridging and dry airmass will greatly limit any effects. For tonight, upper and surface ridging and continued dry air will allow temperatures to drop quickly.
A broad high pressure system remains over the Atlantic this morning and will remain there through Thursday.
Even with warmer afternoon temperatures, nights will still be cool (especially in valleys) with large diurnal ranges expected. - A cold front brings showers and thunderstorms to end the workweek. - Uncertainty remains in the forecast for the weekend concerning rain potential with another cold front.

1157 PM EDT Tue Mar 12 2024 High pressure builds in overnight and Wednesday. Weak low pressure crosses to the south of the area later Thursday into the weekend. Upper level low pressure continues to move slowly east of the Canadian Maritimes. Previous discussion: Surface and upper level ridging will be firmly in place by Wednesday. That said, what little instability that is provided by the low will not amount to much in the way of total snowfall.
Currently - High pressure centered northeast of the Bahamas extends a ridge across Florida and into the northeastern Gulf of Mexico. Zonal flow prevails aloft with the lower to mid level ridge aligned across Cuba. Forecast - The ridge across Florida is expected to lift slightly northwards over the next couple of days. Expect day time highs to range in the lower to mid 80s and lows in the mid 70s. The low level inhibition is expected to hold. The ridge axis is expected to slip back south late in the week and the weekend.
Scattered showers will continue mainly over the higher terrain tonight, and taper off in the lower elevations with the loss of daytime heating. A strong pressure gradient will set up over the Snake Basin late tonight into Wednesday as a low pressure deepens over CO, bringing gusty north-northwest winds especially on Wednesday afternoon. After sunset the chance of showers retreats to the mountains where development will focus near a secondary upper low over the central ID. Wednesday is breezy and cool with northerly flow aloft as the trough digs into the Four Corners region. Wednesday night through Thursday night is dry as a ridge folds into the Pac NW.
127 AM EDT Wed Mar 13 2024 High pressure dome in control of the region is providing a tranquil early evening across SoFlo, with prevailing benign weather conditions and a moderate SE flow turning light overnight. Lows tonight will again be in the low-mid 60s inland, and upper 60s near the coasts.
(Today through Thursday) High pressure will dominate from the North Gulf to over South Texas, with a shallow short wave trough scooting across Texas and east by mid this morning. Deep troughing will initially develop over the Rockies and will then dip south over the Southwest United States as a cutoff low. Baby short wave troughs will ripple overhead through the broader flow, yet with nothing strong enough to generate significant weather locally in the short term. Moderate south southeast breezes will prevail in the short, with breezy conditions for the Lower RGV on Thursday.

935 AM EDT Wed Mar 13 2024 Benign weather conditions prevail across South Florida this morning as high pressure remains in control of the area. The ridge located to our north will keep drifting eastward and shift surface flow to the southeast throughout the day. (Today through Thursday) Stout upper ridging continues to dominate the eastern Gulf of Mexico and South Florida, fostering a benign weather regime. By Thursday, an expansion of upper ridging will be observed across the CWFA, maintaining warm and mostly dry conditions across the region. Afternoon temperatures may be a degree or two warmer on average.
Showers decrease northward today as an upper ridge continues to build into the Pacific Northwest. As the upper ridge builds eastward a thermal trough develops at the southern coast with offshore winds spreading across the east side by Thursday morning. This pattern will bring rapid warming across the region with high temperatures Thursday expected to be almost ten degrees warmer than today's anticipated highs.
445 AM CDT Wed Mar 13 2024 - 20 percent chance of light freezing rain this morning over far north central North Dakota.
729 AM EDT Wed Mar 13 2024 High pressure remains in control today.
Overall expect quiet weather today with temperatures warming up into the lower 70s across much of the valley. Discussion: A weak wave will try to move into the Ohio and Tennessee valley today but persistent ridging and dry airmass will greatly limit any effects. For tonight, upper and surface ridging and continued dry air will allow temperatures to drop quickly.

(This afternoon through Thursday) Benign weather conditions prevail across South Florida as the upper level ridging remains in control of the region. With the assistance of high pressure, the rest of the week is expected to with a dry and stable environment. There will be an expansion of the ridging on Thursday which will allow for a subtle wind shift.
An upper low will dive southward into Arizona by Thursday morning, setting up strong southwest flow aloft over west Texas, with the first of a series of weak disturbances set to move through Thursday afternoon. This will be due, in large part, to a rex blocking pattern over the Western US, leaving the Southern Plains in consistent west to southwest flow.
As the afternoon progresses, activity will continue to push south and west as the low moves quickly to our south.
Tomorrow will much of the same -- only warmer! Upper 70s with a few 80s will be common.
Upper level flow will shift to northerly on the heels of a departing trough of low pressure this afternoon. The atmosphere dries up by Thursday morning as a high amplitude ridge of high pressure builds over the West Coast.
Discussion: Currently mostly clear skies with high pressure over the region and a few passing mid to high level clouds traversing across the region. Temperatures this afternoon are once again warming up very quickly with the dry air in place, about 5 degrees warmer than what we experienced yesterday and about 10 degrees warmer than seasonal normals. Quiet weather will continue overnight and into tomorrow, with the main difference being an even warmer day ahead of the upcoming system.
