Aikyam-Lab/Synoptic-Bench huggingface dataset:
221 PM CDT Sun Mar 23 2025 - Wind gusts will increase into the 40-50mph range this evening after the passage of a cold front. - Quiet weather with seasonable temperatures will prevail for the next several days before a major pattern change brings unsettled weather and much warmer temperatures by the end of the week. 18z/1pm surface analysis shows a cold front just west of the Mississippi River. Gusty winds will continue into Monday, but will slowly subside by late afternoon as high pressure builds eastward toward the Mississippi River.
246 PM EDT Sun Mar 23 2025 A warm front will lift through the area overnight, followed by a cold front Monday afternoon.
1136 AM CDT Sun Mar 23 2025 - Warmer and more humid conditions expected today.
Temperatures will continue to increase through the first half of the week as strong high pressure builds over the region. Temperatures will gradually cool during the latter half of the week, but should remain warmer than normal. Flat ridging resulting in dry quasi-zonal flow persists over the region early this morning with H5 heights hovering around 575dm per objective analysis.
1253 PM MDT Sun Mar 23 2025 - Light snow showers return across the higher elevations of western and northern WY continuing through Monday morning. - Quiet and dry weather returns for much of the upcoming week as potent high pressure builds over the western CONUS.
This is all due to an approaching cold front that is currently stretched from north central Texas into southeast Oklahoma and then into the far northwest portion of Arkansas. Skies will generally clear from northwest to southeast behind the cold front with some lingering mid to high level clouds remaining.
724 PM EDT Sun Mar 23 2025 A cold front will move east across the region this evening into the early morning hours of Monday, bringing widespread showers and possibly a thunderstorm. It will be dry but windy on Monday as low pressure passes well north of the area.
Deeper moisture will continue to gradually spread into the area tonight as the low level flow veers to the west-southwest ahead of a frontal boundary sweeping across the Southeast on Monday. For the start of our work week high pressure will be pushed off in the Atlantic as a cold front start to push through the southeast. This will shift our winds to the south and bring some warmer and more humid air with some areas in the interior expected to get into the upper 80's Monday.
746 PM MDT Sun Mar 23 2025 - Light snow showers continue across the higher elevations of western and northern WY through Monday morning. - Quiet and dry weather returns for much of the upcoming week as potent high pressure builds over the western CONUS.
However, as the low level jet veers a bit more, the moisture and instability axes will also shift east. Deep layer bulk shear has been sufficient for supercells/strong mesocyclones which have aided in hail production tonight. The cold front remains in southern KY through west TN into southeast AR, so a few additional showers and thunderstorms will be possible over the next several hours.
A line of severe thunderstorms associated with a cold front has entered the area, and is set to slowly slide through the area tonight. Convergence in vicinity of the approaching cold front and with some more subtle boundaries of convergence will be the areas of focus for showers and storms into the overnight. The upper-level pattern through the remainder of the week will feature western ridging and eastern troughing with northwest flow between.
Light rain fell along a warm front in western ID late today and this evening.
High clouds associated with the approaching upper-level trough are moving into the region from the southwest. Main update is to gusts ahead of the surface warm front Monday late morning. New sounding guidance suggest deeper mixing which would bring slightly stronger gusts down to the surface from the low-level jet aloft. Surface and upper level ridging will remain over our region this afternoon into the first half of the overnight. Snowfall totals will range from a couple tenths of an inch up to three inches in the higher elevations of the southern Adirondacks and Greens.
602 PM CDT Sun Mar 23 2025 - Wind gusts will increase into the 40-50mph range this evening after the passage of a cold front. - Quiet weather with seasonable temperatures will prevail for the next several days before a major pattern change brings unsettled weather and much warmer temperatures by the end of the week. 18z/1pm surface analysis shows a cold front just west of the Mississippi River. Gusty winds will continue into Monday, but will slowly subside by late afternoon as high pressure builds eastward toward the Mississippi River.
345 PM MDT Sun Mar 23 2025 - Light snow showers return across the higher elevations of western and northern WY continuing through Monday morning. - Quiet and dry weather returns for much of the upcoming week as potent high pressure builds over the western CONUS.
613 PM CDT Sun Mar 23 2025 - Much more seasonal temperatures today as afternoon highs will be in the low to mid 60s.
906 PM EDT Sun Mar 23 2025 Moisture increases tonight ahead of an approaching weak cold front which will bring showers to the region on Monday. increasing clouds are expected through the overnight as an upper trough moves eastward through the Ohio Valley pushing a weak cold front towards the region. Overnight lows expected to be mild with increasing clouds and boundary layer winds remaining elevated with lows in the lower 50s. A cold front will slowly move through the forecast area on Monday.
MOS guidance suggests some of the typically colder spots may briefly approach freezing for a time late tonight/ early tomorrow morning. However, any freezing precluding any freeze headlines. (The rest of today and tonight) Breezy and gusty northwest winds have developed behind a cold front that worked its way through the forecast area this morning and early afternoon. Latest probabilistic data from HREF and NBM continue to indicate temperatures remain above freezing and therefore freeze/frost headlines are not needed at this time, but will monitor trends closely.
Scattered convection has begun to develop across portions of Srn AR/N LA and Deep E TX, along and ahead of a cold front that extends from a JDD, to just S of an ATA to near ADF as of 2330Z.
625 PM CDT Sun Mar 23 2025 (Tonight through Monday night) A large 500mb trough works east across the CONUS, maintaining mostly zonal flow across Deep South Texas, turning a little northwesterly Monday night as the ridge sets up across the Desert SW.
855 PM CDT Sun Mar 23 2025 - Much more seasonal temperatures today as afternoon highs will be in the low to mid 60s.
At the surface, high pressure between Bermuda and the Bahamas had a westward extension into the eastern Gulf. Dew points were in the lower and middle 60s. While the main troughing should be east of the area by midday, if any isolated storms can develop, they will again bring a threat of hail.
135 AM EDT Mon Mar 24 2025 - Wind gusts of 30 to 40 mph overnight behind a cold front.
Tuesday evening opens the period with an upper level ridge moving towards the region from the west and high pressure moving in at the surface.
A cold front currently drapes southwestward into eastern Kentucky and along the Cumberland Plateau where a shift to northwesterly winds and cooler temperatures can be noted.
104 AM CDT Mon Mar 24 2025 - Much more seasonal temperatures today as afternoon highs will be in the low to mid 60s.
A closed upper low will become centered over the Eastern Great Lakes while the base of the mid-level broad trough will swing east of the area during the day on Monday. The surface cold front will decelerate as it continues moving southeast, barely clearing the forecast area by Monday evening. Winds will become northwest behind the surface cold front with speeds from 5-10 mph. High temperatures will range from around 70 far north and across the higher elevations east to the mid 70s south and southwest.
(Tonight through Tuesday Night) A cold front will push east of Middle TN early Monday morning with dry weather setting in.
251 AM EDT Mon Mar 24 2025 A cold front approaches and moves through the area today into tonight. - Cold front passes through this afternoon. This activity is ahead of an advancing cold front, and it should remain just west of the area for much of the night. Morning lows in the low to middle 50s still on track. Highs today outside of an rainfall should reach the lower 70s, with temperatures in rainfall dipping back into the 60s. On Tuesday, the front will have moved offshore, but upper level troffing will remain in place. Therefore, while dry air will move back in, the low level pressure gradient will remain a bit nebulous, keeping wind speeds down.
(Today through Tuesday night) It'll be a beautiful couple of spring days to start the work week, thanks to ridging and stagnant flow atop the southern Plains. A pair of weak cold fronts will encroach upon the Panhandles today and tomorrow, but will have little to no impacts on our weather.
Radar is filling in across central New York along a relative warm front associated with a mature low pressure centered over the Great Lakes that is beginning to lose its baroclinicity. Higher elevations could pick up additional snowfall, but the pattern and late March sun angle do not support much in the way of gain for the high elevation snowpack.
- Dry weather and warmer temperatures continue through the week. Mostly quiet and dry conditions will be the main weather story through the short term as upper level ridging builds to the west. Despite this, high temperatures will still rise into the mid 60s in the north to the low 70s south of I-80. Dry conditions continue through the remainder of the week as upper level ridging slowly shifts across the central Plains.
930 PM PDT Sun Mar 23 2025 Warmer weather will prevail Monday as high pressure aloft continues to build. Tuesday will continue the warming trend in the mountains and deserts, but slight cooling will occur west of the mountains as the ridge shifts east.
115 AM EDT Mon Mar 24 2025 A cold front will move east across the region this evening into the early morning hours of Monday, bringing widespread showers and possibly a thunderstorm. It will be dry but windy on Monday as low pressure passes well north of the area.
The cold front itself is just now moving across far northwest Alabama with an outflow boundary racing south and east ahead of the front. Continued dry weather on Tuesday with generally sunny skies as a brief high pressure zone builds in.
Strong high pressure over the region will keep the active weather at bay with temperatures well above normal.
Up to 4" of snow is possible on the highest peaks. An upper-level ridge continues to build in from the west over the next 36 hours leading to warm and predominately dry conditons. Accumulation will mainly occur on the highest peaks where up to 4" is expected. High pressure will be in control Tuesday, with clear skies and sunshine dominating.
Weak surface ridging will reside across the Northern Plains on Monday. Temperatures will continue to warm through the rest of the week as upper level ridging slides eastwards from the western CONUS.
- Turning cooler and unsettled late in the week. Under the increasing influence of a broad ridge of high pressure building northeast across the NRN Rockies, temperatures will continue on a warming trend through midweek as conditions trend very dry outside of a few isolated mountain showers today. This strong ridge of high pressure will support the warmest temperatures we have seen so far this year with well above normal temperatures expected early this week.
(Today through Tuesday) Cold front sagging south this morning and will stall by mid morning around 9-10am.
NW flow aloft as 500 mb ridge builds into British Columbia into Tuesday, then flow flattens some as next 500 mb low moves east to just west of Oregon/Washington.
Thunder is out of the question with the parent cyclone displaced so far to the north (over the northeast states by Tuesday morning).
1220 AM CDT Mon Mar 24 2025 - Wind gusts will increase into the 40-50mph range this evening after the passage of a cold front. - Quiet weather with seasonable temperatures will prevail for the next several days before a major pattern change brings unsettled weather and much warmer temperatures by the end of the week. 18z/1pm surface analysis shows a cold front just west of the Mississippi River. Gusty winds will continue into Monday, but will slowly subside by late afternoon as high pressure builds eastward toward the Mississippi River. Barnes As high pressure shifts away from the region, a weak disturbance will bring clouds and perhaps a few light showers Monday night into Tuesday.
A cold front over Central Texas, the Hill Country, Edwards Plateau, and Val Verde County will continue to move to the south across much of the rest of South Central Texas today. The front dissipates or lifts back north later tonight into Tuesday allowing a southerly flow to return along with a warmer airmass. Forcing is minimal and weak upper level ridging eases over our area.
1236 AM CDT Mon Mar 24 2025 Cleared some of SVR watch #63 across the northern fridge of previously included Counties and Parishes. (Tonight through Tuesday Night) The cold front continues to make good progress into the ArkLaTex stretching from Tyler to Longview and Marshall and is currently knocking on the door in the SHV/BO metro area.
As of 19z/2 PM this afternoon, we continue to see a few areas of light to moderate rain showers as a weak surface cold front continues to sweep through the area. The cold front is currently located along a line from Memphis, MO to Manchester, IA and will continue to sweep eastward with time. In the wake of the cold front, low-level lapse rates are progged to steepen per the 23. As we go into late tonight through the day Monday, drier air will filter into the region, along with an area of high pressure building across the southern Mississippi River valley for Monday.
343 AM EDT Mon Mar 24 2025 It will be dry but windy today as low pressure passes well north of the area.
Cleared some of SVR watch #63 across the northern fridge of previously included Counties and Parishes. (Tonight through Tuesday Night) The cold front continues to make good progress into the ArkLaTex stretching from Tyler to Longview and Marshall and is currently knocking on the door in the SHV/BO metro area.
1050 PM MDT Sun Mar 23 2025 - Light snow showers continue across the higher elevations of western and northern WY through Monday morning. - Quiet and dry weather returns for much of the upcoming week as potent high pressure builds over the western CONUS.
Currently at the surface, the subtropical ridge of high pressure is extending from the western Atlantic across the Florida Peninsula, keeping southerly low level in place and resulting in temperatures and humidity to continue to climb higher this afternoon. Tonight and Tuesday, an upper level trough will dig into the northeastern US, pulling a decaying cold front into the Florida Peninsula.
However, as the low level jet veers a bit more, the moisture and instability axes will also shift east. Deep layer bulk shear has been sufficient for supercells/strong mesocyclones which have aided in hail production tonight. The cold front remains in southern KY through west TN into southeast AR, so a few additional showers and thunderstorms will be possible over the next several hours. High pressure will build back into the Tennessee Valley by Tuesday, with another good warm up into the low to mid 70s likely.
(Monday through Tuesday) Quiet, yet warmer than normal weather will continue through the beginning of the workweek across the Four State Region. This is due to post-frontal surface ridging that stays in place over the area, keeping winds below 5 mph and allowing any rainfall to maximally radiate back into the atmosphere through enhanced evapotranspiration conditions. What this ultimately means is higher dew points and higher temperatures (maximums/minimums in the 80s/upper 50s), especially by tomorrow as the warm front approaches from the south (upper 80s as temperature maximums are likely tomorrow!). Long-range guidance is in more agreement on the timing than the intensity of the trough, but ultimately a wet weekend is becoming more likely for the end of the month.
------------------------------------------------------------------- Latest radar imagery shows overrunning precipitation associated with low pressure over the Great Lakes well east of PGH, mostly over the ridges. The eastward trend will continue early this morning, and rapid update hi-res guidance has been fairly consistent in showing all activity east of the ridges by sunrise.
1242 AM CDT Mon Mar 24 2025 A line of severe thunderstorms associated with a cold front has entered the area, and is set to slowly slide through the area tonight. Convergence in vicinity of the approaching cold front and with some more subtle boundaries of convergence will be the areas of focus for showers and storms into the overnight.
310 AM CDT Mon Mar 24 2025 - Rain likely across portions of western and south western North Dakota today, with a slight chance of freezing rain this morning. - Cooler weekend with chances of rain and snow Currently a clipper system is moving into northern Montana, with light rain falling in eastern Montana in the warm sector. A slight chance of freezing rain is possible in southeast North Dakota this morning between 09z and 14z.
The front will bring some slightly cooler air to the area Monday night, but that will not last as the boundary washes out/retreats back to the north.
Similar conditions expected Tuesday as high pressure lies to our east.
1220 AM CDT Mon Mar 24 2025 (Tonight through Monday night) A large 500mb trough works east across the CONUS, maintaining mostly zonal flow across Deep South Texas, turning a little northwesterly Monday night as the ridge sets up across the Desert SW.
301 AM EDT Mon Mar 24 2025 - Windy With Snow Showers Today - Tranquil And Cool Weather Tonight Through Midweek - Moderating Temperatures Late This Week and Weekend - Windy With Snow Showers Today Lake enhanced snow showers will continue to develop today as a strong low pressure system moves slowly east across far northern lower MI. H8 temps will fall to -8 to -9 C with deeper moisture in place with the upper trough axis overhead.
318 AM CDT Mon Mar 24 2025 - Mild temperatures expected the first half of the workweek, followed by much warmer conditions.
Combined with the continued dynamic support expect additional widely scattered showers/sprinkles again on Monday, potentially with some wet snowflakes early Monday morning from Hwy 20 northward, and possibly into Tuesday before the upper ridge axis builds far enough eastward to take us out of northwest flow and get the region under large scale subsidence for midweek. Temperatures will be warming over the next few days with highs ranging from the low/mid 60s north along the SD border to the lower 70s south of I-80, and overnight lows will generally be in the 30s. Ensemble guidance is in good agreement in breaking down the upper ridge over the western US and gradually moving it eastward through mid to late week.
(Today) The cold front has moved about halfway through the CWA at this hour.
Hazardous travel is still possible for the morning commute due to snow covered roads and bridges.
Winds should frequently gust to 40mph as the low moves over this morning. If the low can hold together over the next few hours, a gale warning will also be issued at least for the near shore and inland waters for these winds. (Today through Tuesday) Cold front sagging south this morning and will stall by mid morning around 9-10am.
621 AM CDT Mon Mar 24 2025 (Monday through Tuesday) Quiet, yet warmer than normal weather will continue through the beginning of the workweek across the Four State Region. This is due to post-frontal surface ridging that stays in place over the area, keeping winds below 5 mph and allowing any rainfall to maximally radiate back into the atmosphere through enhanced evapotranspiration conditions. What this ultimately means is higher dew points and higher temperatures (maximums/minimums in the 80s/upper 50s), especially by tomorrow as the warm front approaches from the south (upper 80s as temperature maximums are likely tomorrow!). Long-range guidance is in more agreement on the timing than the intensity of the trough, but ultimately a wet weekend is becoming more likely for the end of the month.
High pressure builds into the region through at least the middle of the week, bringing a stout warming trend across the forecast area.
The low pressure system that brought mixed precipitation yesterday continues to move northeast through Michigan.
621 AM CDT Mon Mar 24 2025 - Mild temperatures expected the first half of the workweek, followed by much warmer conditions.
731 AM EDT Mon Mar 24 2025 - Windy With Snow Showers Today - Tranquil And Cool Weather Tonight Through Midweek - Moderating Temperatures Late This Week and Weekend - Windy With Snow Showers Today Lake enhanced snow showers will continue to develop today as a strong low pressure system moves slowly east across far northern lower MI. H8 temps will fall to -8 to -9 C with deeper moisture in place with the upper trough axis overhead.
238 AM PDT Mon Mar 24 2025 Warmer today under a ridge of high pressure with weak offshore flow.
Radar returns are not as intense as first thing this morning when the trough axis moved through, but still seeing visibilities in the 1 to 2 mile range. Looking at webcams snow is largely sticking to bridges/overpasses and along and north of the US-10 corridor. - Windy With Snow Showers Today Lake enhanced snow showers will continue to develop today as a strong low pressure system moves slowly east across far northern lower MI. H8 temps will fall to -8 to -9 C with deeper moisture in place with the upper trough axis overhead.
Issued 418 AM CDT Mon Mar 24 2025 Today through Tuesday: A nebulous area of snow showers tied to a southwest-extending lobe of the upper low overhead will continue marching eastward over the area this morning. Some brief drops in visibility may occur with the "heavier" pockets of snow, but the transient and overall light nature of the snow, coupled with temperatures right around freezing, will keep accumulations light. Subsidence is expected as the upper low exits, and snow showers should largely end over the area around dawn, save for Sheboygan County where they may linger until late morning. Winds will ease somwhat this afternoon, but gusts from 30 to 35 mph will be common area-wide until tonight, when our lapse rates become more neutral in the low levels, and we decouple from the better momentum aloft.
High pressure continues to build over northern AZ, bringing clear skies, light winds, and near record high temperatures during the beginning of the week.
- Strong ridging builds across the Intermountain West this week, with much above normal temperatures.
651 AM EDT Mon Mar 24 2025 It will be dry but windy today as low pressure passes well north of the area.
Temperatures across the island chain are warmer than last night recording in the mid 70s currently. For today, high pressure over the Atlantic will stretch westward over Florida resulting in our east to southeast breezes slackening. Tonight, moisture content will improve in the lower levels but not by a significant amount so only a slight chance of light rain could be seen.
1040 AM EDT Mon Mar 24 2025 It will be dry but windy today as low pressure passes well north of the area.
623 AM CDT Mon Mar 24 2025 (Today) The cold front has moved about halfway through the CWA at this hour.
949 AM EDT Mon Mar 24 2025 A cold front will move through the area overnight, then another front will move through Tuesday night.
