Aikyam-Lab/Synoptic-Bench huggingface dataset:
A cold airmass will remain in place across the region through at least midweek when high pressure will move in, bringing dry, stable conditions.
406 AM MST Tue Jan 14 2025 KEY MESSAGES: - Warmer temperatures will prevail through the midweek. - The next cold front will arrive late week with snow showers and markedly colder shift in temperatures for the weekend. WEATHER PATTERN OVERVIEW: Upper ridge setting up over the Pacific Northwest will bring chinook warming well into the northern plains.
448 AM PST Tue Jan 14 2025 Conditions through Wednesday will be dry across the region as high pressure builds in. Today through Wednesday: The ridge pattern will continue over the Pacific Northwest. Mid to upper level clouds will spill over the top of the ridge and pass through the area. Wind shifts in the low levels keeps the placement of fog a guessing game as near surface moisture is sloshed around.
The 500 mb pattern is stabilizing as an elongated ridge over northern California and a vertically stacked, cut-off low roughly 500 miles west of Baja.
This combined with some mid and high level clouds thanks to the upper level jet, low temperatures will remain above freezing across the southern third of our CWA.
A trough of low pressure stretched across western Lake Superior and northern Minnesota early this morning. Light snow showers were observed on radar across northeastern Minnesota and northwestern Wisconsin, but this was showing a downward trend as the trough moved through. High pressure will build into the Upper Midwest today with partly to mostly sunny skies. As the high moves into the Ohio Valley tonight into Wednesday, southerly return flow in the wake of the high will bring near to above normal temperatures into the Northland. While we won't reach freezing, readings in the 20s will be noticeably warmer than the past few days.
543 AM CST Tue Jan 14 2025 (Today through Wednesday) High pressure will slide into the area today and bring a very dry airmass into the region.
622 AM EST Tue Jan 14 2025 Cold and dry conditions through much of the week as a series of high pressure centers move over the area. Aloft, a relatively flat ridge keeps a more westerly wind component over the CWA. Off to the west, a weak, positively tilted trough swings down over the Rockies, before diving toward the south. There could be a quick burst of snow at the TN/NC border, but confidence is low given the amplifying high pressure and lack of any real moisture. A few areas at the higher elevations could dip below zero, but remain above criteria for any cold products.
This is due to surface ridging centered over the area that will shift eastward, keeping winds light in the process.
Upper level ridge over Western Washington through Wednesday will weaken Wednesday night.
405 AM EST Tue Jan 14 2025 An Arctic cold front will move southeast across the region today, bringing a quick burst of snow. High pressure will then gradually build back into the region on Wednesday.
Breezy to locally windy northeast winds return for the coastal headland and exposed ridges this weekend. High pressure building over the Pacific Northwest and Northern California is promoting northeasterly winds aloft. Low temperatures are generally in the low to mid 30's for the coastal valleys, mid 20's to low 30's for Trinity valleys, and mainly in the 50's in the ridges. With dewpoints in the low to mid 30's, low temperatures has been struggling to drop to low 30's for the coastal areas and southern interior Mendocino.
236 AM PST Tue Jan 14 2025 Conditions through Wednesday will be dry across the region as high pressure builds in. Today through Wednesday: The ridge pattern will continue over the Pacific Northwest. Mid to upper level clouds will spill over the top of the ridge and pass through the area. Wind shifts in the low levels keeps the placement of fog a guessing game as near surface moisture is sloshed around.
633 AM EST Tue Jan 14 2025 An Arctic cold front will move southeast across the region today, bringing a quick burst of snow. High pressure will then gradually build back into the region on Wednesday.
511 AM CST Tue Jan 14 2025 (Today through Wednesday) Not much in the way of any issues over the next several days as high pressure builds in over the Lower Mississippi valley.
High pressure will be centered over western and southern MN by this afternoon and winds will drop off accordingly. The high will drift southeast to the Ohio Valley Wednesday and warm air advection will start bringing in a much milder Pacific airmass. A low pressure system over Hudson Bay and a warm front stretching south into the mid Missouri Valley will bring increased cloud cover to the region, and the moisture depth may be deep enough in WI to allow for some very light snow or flurries to develop in the Wednesday afternoon and evening.
710 AM EST Tue Jan 14 2025 A cold front is currently located across the central Florida peninsula, and will move southeast across the remainder of the forecast area through the early morning hours. High pressure will build over the Florida peninsula in the wake of the front today with drier cooler air advecting across the region. Mid/upper level moisture will overrun the cooler air tonight and Wednesday which will cause increasing cloudiness across west central and southwest Florida. Combination of the increasing moisture and a cold front associated with a weak U/L trough expected to move across the southeast U.
628 AM EST Tue Jan 14 2025 High pressure will prevail through the week. Another low pressure system and associated cold front will impact the region this weekend. The center of a 1030mb high will remain centered over the lower Mississippi River Valley, ridging east over the forecast area. High pressure at the surface will prevail across the local forecast area through the week.
204 AM PST Tue Jan 14 2025 * A chilly morning will give way to a milder afternoon, with breezy northeasterly winds continuing along and west of Sierra ridges throughout the day. * By Wednesday, lighter winds and valley inversions will settle in, resulting in cold nights and moderately warmer afternoons. * This weekend, a cold front may bring another round of gusty northeast winds and cooler temperatures. Today: * Gusty east-northeast ridge winds will peak this morning, with crest gusts reaching 50-60 mph.
(Now through Wednesday night) An elongated upper trof stretching from the northeastern states to the 4 Corners region evolves into a meridionally oriented upper trof over the eastern states. Lows tonight range from the lower 30s well inland to the upper 30s at the coast, then Wednesday night will have similar temperatures except for a tad warmer near the coast.
Upper level pattern looks to remain on track to previous forecasts, as ridging remains firmly in place in the PacNW, and a closed cut-off low is present off-shore SoCal.
518 AM CST Tue Jan 14 2025 Dry and warming continues through the end of the week with highs in the low 40s and lows in the 20s.
(Rest of Today) High pressure will promote mostly clear and calm conditions across the Tennessee Valley today.
(Today through Wednesday) Not much in the way of any issues over the next several days as high pressure builds in over the Lower Mississippi valley.
Temperatures have been very slowly falling through the afternoon in the wake of the cold front passage. Sand Key is still flirting with sustained winds of 17 to 18 knots and occasional gusts into the low 20s. The recent cold front will continue to slide southward and stall somewhere over or close to Cuba. Meanwhile, high pressure will fill in behind this front.
As some additional high clouds move in during the overnight hours across the southern half of the CWA, it could actually prevent locations along and south of the I-85 corridor from dropping below the freezing mark. A surface cold front will approach from the north during the day on Wednesday, but is expected to stall over northern Alabama.
1022 AM EST Tue Jan 14 2025 An Arctic cold front will move southeast across the region today, bringing a quick burst of snow. High pressure will then gradually build back into the region on Wednesday.
Low pressure will bring milder temperatures and rain chances back to the Carolinas for the weekend. Winds grow lighter and back in direction tonight as a poorly defined cold front approaches from the NW. Even so the CAA following the boundary will cap highs in the low 40s, some 15 degrees below normal. Lows will be in the lower 20s with some spots in the teens.
Only exception is along and north of the I-30 corridor where snow pack remains visible on satellite, keeping obs a few degrees cooler. This is due to surface ridging centered over the area that will shift eastward, keeping winds light in the process.
1128 AM CST Tue Jan 14 2025 Dry and warming continues through the end of the week with highs in the low 40s and lows in the 20s.
327 PM EST Tue Jan 14 2025 High pressure will prevail through the week. Another low pressure system and associated cold front will impact the region this weekend. Low temperatures will generally dip into the lower 30s for most areas inland.
948 AM PST Tue Jan 14 2025 Conditions through Wednesday will be dry across the region as high pressure builds in. Today through Wednesday: The ridge pattern will continue over the Pacific Northwest. Mid to upper level clouds will spill over the top of the ridge and pass through the area. Wind shifts in the low levels keeps the placement of fog a guessing game as near surface moisture is sloshed around.
Low clouds and patches of dense freezing fog will remain in the forecast across lower elevations. Inversion conditions should actually strengthen a bit as the ridge builds farther east. Otherwise, expect more sun and warmer conditions outside/above of the inversion.
1059 AM EST Tue Jan 14 2025 High pressure will prevail through the week. Another low pressure system and associated cold front will impact the region this weekend. High pressure at the surface will prevail across the local forecast area through the week.
1116 AM CST Tue Jan 14 2025 (Rest of Today) High pressure will promote mostly clear and calm conditions across the Tennessee Valley today.
1100 AM CST Tue Jan 14 2025 - A reinforcing shot of arctic cold will come with another cold front's passage today.
Cold front is marching across the Keys currently. The leading edge of the front has cleared the Lower Keys and in the process of passing through the Middle and Upper Keys. There was a faint line of showers along the leading edge but nothing more than sprinkles have fallen in the Lower and Middle Keys. Given the faster nature of this cold front, did make a few changes to the going forecast. Small Craft Exercise Caution headline is in effect for the outer Gulf waters in the wake of the ongoing cold front passage. (15Z TAFS) A cold front will continue to progress through the Island Chain after the next several hours.
Otherwise, the ridging pattern we've been experiencing for a while looks to remain in place for the foreseeable future.
203 PM CST Tue Jan 14 2025 - Areas of dense freezing fog may occur (30-50% chance) across central Kansas tonight, including locations such as Hays and Larned.
1132 AM CST Tue Jan 14 2025 (Today through Wednesday) Not much in the way of any issues over the next several days as high pressure builds in over the Lower Mississippi valley.
The cold front that pushed through last night is now just north of the Keys this afternoon.
128 PM EST Tue Jan 14 2025 An Arctic cold front will move southeast across the region today, bringing a quick burst of snow. High pressure will then gradually build back into the region on Wednesday.
(Tonight) Tranquil weather across the Tennessee Valley continues late this afternoon and evening, with high pressure promoting clear/calm conditions. Low temperatures in the low to mid 20s will be common by early Wednesday. A low chance for some patchy freezing fog will be possible late tonight, mainly in sheltered valleys.
1257 PM EST Tue Jan 14 2025 Cold and dry conditions through much of the week as a series of high pressure centers move over the area. Reinforcing high pressure will build into the area thru Wed. Temperatures will fall into the lower teens in the high elevations tonight, and wind chills should easily drop below zero, with -5 or slightly colder possible in a few spots.
253 PM CST Tue Jan 14 2025 - Patchy blowing and drifting snow is possible tomorrow as winds pick up and warmer temperatures move into the area.
141 PM CST Tue Jan 14 2025 - Overnight refreezing and black ice concerns for the morning commute continue for most of the week.
Otherwise, dry and stable conditions prevail as an upper ridge builds in from the west. High pressure building in from the west will strengthen an inversion through midweek.
(This evening through Wednesday night) Upper pattern this afternoon shows an upper trough over the Great Lakes and New England with an upper ridge off the Pacific Coast. With an upper low south of the ridge, this is producing a split flow, with our CWA primarily in the southern split. Currently, the surface pattern has high pressure across much of the Mississippi River Valley. Any rain amounts much more than about a tenth of an inch will be surprising, as there is a lot of dry air in the lower levels to overcome. Just as the lower layers get saturated, the best lift pulls away to the east. Fairly extensive cloud cover should hold temperatures above freezing across the area tonight and Wednesday night, and will likely have a negative impact on high temperatures tomorrow.
Ridging over the northeastern Pacific has tilted eastward north of the newly formed closed low off the California coast, with the ridge axis now directly over the Pacific Northwest. This ridge will continue to be in control for the remainder of the week, either directly overhead,or centered just offshore once the ridge retrogrades later this week and into the weekend. Expect fog/freezing fog and low clouds each overnight and morning for most valleys west of the Cascades. Otherwise, temperatures will generally see a gradual warming trend through the week, although any areas in more persistent fog or low clouds may stay cooler with very little change in temperature.
349 PM MST Tue Jan 14 2025 KEY MESSAGES: 1) Warmer temperatures will continue through the midweek. 2) The next cold front will arrive late in the week with snow showers, breezy northwest winds, and markedly colder temperatures. WEATHER PATTERN OVERVIEW: Upper ridging will lead to chinook warming over the Northern High Plains through the midweek, and cloudiness from time to time.
Dry weather will prevail through the majority of the week into the weekend as high pressure builds across the Pacific Northwest.
A cold front on the leading edge of high pressure north of the Four State Region will backdoor into the northern zones this evening, before diffusing out through the afternoon tomorrow, somewhere between the I-30 and I-20 corridor.
High pressure will result in a gradual warming trend through the end of the work week, in addition to dry and stable conditions.
333 PM PST Tue Jan 14 2025 Conditions through Wednesday will be dry across the region under a ridge of pressure.
529 PM CST Tue Jan 14 2025 (This evening through Wednesday night) Upper pattern this afternoon shows an upper trough over the Great Lakes and New England with an upper ridge off the Pacific Coast. With an upper low south of the ridge, this is producing a split flow, with our CWA primarily in the southern split. Currently, the surface pattern has high pressure across much of the Mississippi River Valley. Any rain amounts much more than about a tenth of an inch will be surprising, as there is a lot of dry air in the lower levels to overcome. Just as the lower layers get saturated, the best lift pulls away to the east. Fairly extensive cloud cover should hold temperatures above freezing across the area tonight and Wednesday night, and will likely have a negative impact on high temperatures tomorrow.
427 PM MST Tue Jan 14 2025 - Cool, dry, and generally mild today and slightly warmer Wednesday.
650 PM CST Tue Jan 14 2025 - Patchy blowing and drifting snow is possible tomorrow as winds pick up and warmer temperatures move into the area.
Winds will begin to tamper as we go through this evening as the center of the high pressure moves closer to the area.
209 PM PST Tue Jan 14 2025 Conditions through Wednesday will be dry across the region under a ridge of pressure.
239 PM MST Tue Jan 14 2025 - Cool, dry, and generally mild today and slightly warmer Wednesday.
Low pressure will bring milder temperatures and rain chances back to the Carolinas for the weekend. Forecast on track for mainly clear weather tonight, and winds to back to the SW ahead of a cold front. Updated aviation discussion below Winds grow lighter and back in direction tonight as a poorly defined cold front approaches from the NW. Even so the CAA following the boundary will cap highs in the low 40s, some 15 degrees below normal. Lows will be in the lower 20s with some spots in the teens.
508 PM CST Tue Jan 14 2025 - Overnight refreezing and black ice concerns for the morning commute continue for most of the week.
440 PM CST Tue Jan 14 2025 - Areas of dense freezing fog may occur (30-50% chance) across central Kansas tonight, including locations such as Hays and Larned.
Another round of morning fog and low stratus expected Wednesday as high pressure continues to persist over Western Washington.
(Now through Wednesday night) An elongated, largely positively tilted upper trough stretching from the northeastern states to the 4 Corners region evolves into a meridionally oriented upper trough over the eastern states. Lows tonight and Wednesday night range from the lower 30s well inland to around 40 degrees at the coast.
Widespread freezing temperatures are forecast across mainly rural areas of the San Joaquin Valley through Wednesday morning. A ridge of high pressure continues to hold influence over Central California, leading to clear skies and cold overnight lows. Freezing low temperatures are expected in the rural areas of the San Joaquin Valley through tomorrow morning, with a 30 to 60 percent chance for lows of 32 degrees or lower in the cities in the Central San Joaquin Valley, such as Hanford and Delano.
Updated Aviation Discussion Quiet weather conditions will continue over the next couple of days as overnight temperatures will slowly warm, resulting in more isolated areas of freezing temperatures. This warming trend will be short-lived as a weak weather system brings marginal precipitation chances, but much cooler weather heading into and through this weekend. An upper low has now retrograded well offshore of the West Coast, with high amplitude ridging centered across the central West Coast. Temperatures across the region are set to warm over the next couple of days as the influence of the upper level low lessens and mid-level heights build over Arizona.
(Tonight) A secondary dry cold front will make its way through the TN Valley over the next few hours. With additional high pressure moving in behind the front, the frontal passage will act to reinforce the current dry continental airmass. This will keep dewpoints in the 20s and drop overnight lows into the low to mid 20s. The light winds and mostly clear skies will create a low chance for freezing fog with best changes in sheltered valleys.
530 PM CST Tue Jan 14 2025 - Patchy blowing and drifting snow is possible tomorrow as winds pick up and warmer temperatures move into the area.
314 PM MST Tue Jan 14 2025 Quiet weather conditions will continue over the next couple of days as overnight temperatures will slowly warm, resulting in more isolated areas of freezing temperatures. This warming trend will be short-lived as a weak weather system brings marginal precipitation chances, but much cooler weather heading into and through this weekend. An upper low has now retrograded well offshore of the West Coast, with high amplitude ridging centered across the central West Coast. Temperatures across the region are set to warm over the next couple of days as the influence of the upper level low lessens and mid-level heights build over Arizona.
Current forecast on track with cool dry conditions expected overnight as high pressure continues building into the region in the wake of a recent cold front. Will monitor area of mid/upper clouds across the Nature Coast this evening into overnight that could keep temps a few degrees warmer if they persist, which would temper frost potential in that area. The cold front that pushed through last night is now just north of the Keys this afternoon.
1014 PM MST Tue Jan 14 2025 - 40% chance for freezing fog in eastern Graham and Norton counties Wednesday morning.
359 AM EST Wed Jan 15 2025 Snow continues this morning mainly focused on mid elevations sloping up into the higher terrain.
139 AM MST Wed Jan 15 2025 High pressure remains in firm control of the weather across the region with the only concern today and tomorrow being stratus and/or fog. This could linger across the Arco Desert/INL areas and parts of the upper Snake Plain throughout the day with some occasional breaks while the rest of the area will likely see ample sunshine with high pressure in place.
125 AM EST Wed Jan 15 2025 An Arctic cold front will cross the region overnight tonight into Wednesday morning. Arctic high pressure on Wednesday will remain in place before shifting south into the Gulf states late in the week. A cold front and associated storm system will move east across the region this weekend. The well mixed boundary layer and breezy winds along and ahead of the front have keep temperatures in the lower 40s in the central and southern Foothills into the Triad, with temperatures in the central and east varying by 10-15 degrees (depending on mixing). The cold front will surge through overnight with CAA arriving behind the front. Arctic high pressure over the Mid MS valley will gradually shift into the southern Appalachians.
1135 PM CST Tue Jan 14 2025 - Patchy blowing and drifting snow is possible tomorrow as winds pick up and warmer temperatures move into the area.
The clouds will keep temperatures warmer compared to last night and most areas will see overnight lows in the mid 30s to mid 40s. A few spots across northern Val Verde into northern Edwards counties could see temperatures drop to near freezing as low clouds may not move into this area until sunrise Wednesday. Look for overnight lows in the lower 30s to lower 40s.
955 PM PST Tue Jan 14 2025 Conditions through Wednesday will be dry across the region under a ridge of pressure.
1156 PM CST Tue Jan 14 2025 Seasonable weather remains on track for tonight, with overnight lows dipping just below freezing north of I-20 and slightly above freezing to the south. High pressure remains firmly rooted in place, ensuring calm and benign conditions in the short, with light and variable winds prevailing.
Cooler and breezy today with mountain snow continuing into the afternoon. Low level moisture will continue to stream in behind upper trough today as general cyclonic flow translates eastward.
1038 PM CST Tue Jan 14 2025 (Tonight) A secondary dry cold front will make its way through the TN Valley over the next few hours. With additional high pressure moving in behind the front, the frontal passage will act to reinforce the current dry continental airmass. This will keep dewpoints in the 20s and drop overnight lows into the low to mid 20s. The light winds and mostly clear skies will create a low chance for freezing fog with best changes in sheltered valleys.
The only difference on Wednesday will be a weakening thermal trough.
235 AM EST Wed Jan 15 2025 Weak low pressure will move east through the Maritimes today.
1040 PM CST Tue Jan 14 2025 - Areas of dense freezing fog may occur (30-50% chance) across central Kansas tonight, including locations such as Hays and Larned.
Currently - A cold front is limping southwestward through the broader area this evening. High pressure driving the post cold front breezes is consolidating over the eastern United States. Despite freshening breezes, winds at the lowest levels are already northeasterly. Temperatures are currently in the mid to upper 60s with dew points in the lower 60s.
