626 AM EST Fri Jan 24 2025 High pressure will shift east today across portions of the Southeast and Mid-Atlantic, sliding offshore early this weekend. A weak cold front will pass through the region tonight, keeping temperatures below average for Saturday.
453 AM CST Fri Jan 24 2025 (Today) In wake of a dry cold front that will be passing through the region early this morning, a slightly cooler day will be on tap for region as northwesterly winds reinforce this cool/dry air mass.
410 AM EST Fri Jan 24 2025 High pressure will shift east today across portions of the Southeast and Mid-Atlantic, sliding offshore early this weekend. A weak cold front will pass through the region tonight, keeping temperatures below average for Saturday.
903 AM EST Fri Jan 24 2025 High pressure will gradually build east into the central Great Lakes and middle Ohio Valley today. The high will then move east of the area tonight.
659 AM EST Fri Jan 24 2025 High pressure will gradually build east into the central Great Lakes and middle Ohio Valley today. The high will then move east of the area tonight.
This second cold front could bring another round of light snow or flurries to the area on Saturday with the best chance (20-40 percent) across central and north-central Wisconsin where the best moisture will coincide with a vigorous mid-level PV anomaly.
449 AM CST Fri Jan 24 2025 (Today through Saturday Night) After the cold front moved through the state on Thu. NW winds and drier/cooler air has moved back into the state. Temps early this Fri morning have dropped into the low teens to mid 20s across much of the area. These SRLY winds will bring increased moisture by Sat afternoon ahead of an approaching cold front. Moisture levels look to become high enough ahead of this approaching cold front to trigger some rainfall across portions of the area Sat night as the front drops SE into the state.
Otherwise clear skies and warmer temperatures for both highs today and lows overnight as the cold airmass moves out. A cold front will move into northwest Oklahoma before sunrise, but the primary effects with this front will be later in the day.
304 AM CST Fri Jan 24 2025 Below normal temperatures will persist through the short term in the wake of a reinforcing cold front.
505 AM CST Fri Jan 24 2025 Updated at 503 AM CST Fri Jan 24 2025 - Warmer temperatures today and Saturday.
An upper level trough approaching from the north will generate snow over the forecast area, and temporarily end the northerly flow that keeps replenishing the arctic air over this part of the Gem State. Precipitation amounts are also lower in the highlands, with no amounts exceeding 4. Still expecting breezy to windy conditions from the northeast behind the low on Sat, which will mean very low wind chills for during the day Sat and by Sat night it is likely that Extreme Cold Warnings will be needed for Sat night/Sun morning. So enjoy the end of the warming trend today and the "mild" night tonight, as the cold air will return once the low slides to the south during the day Sat.
Surface analysis depicts Arctic high pressure covering the eastern half of the CONUS.
A Pacific Northwest storm system will move into the Great Basin today, bringing a cold front into northern Utah that will bring snow late Friday into Saturday.
KEY MESSAGES: - Light snow/flurries expected north and along ridges today, travel impacts are not expected. Upsloping with residual moisture may initiate some light snow activity along the ridges of PA/WV through this afternoon, adjustments have been made to the PoPs. A trough may spark off some snow showers north of I-80 in the afternoon, but the chance for >0. Highs will reach the low 30s with better confidence across the board which is still a few degrees below average.
708 AM EST Fri Jan 24 2025 The area of low pressure and frontal boundary that has been lingering over the area the past few days will gradually move eastward into the western Atlantic through the day. Interaction between this front moving into the western Atlantic and strong high pressure over the eastern seaboard will keep a continued predominant northerly wind flow over the region for the next few days. The upper level troughing that has been lingering over the eastern half of the U. High pressure also moves over the southeast U.
Updated at 415 AM CST Fri Jan 24 2025 - Warmer temperatures today and Saturday.
942 AM EST Fri Jan 24 2025 High pressure will shift east today across portions of the Southeast and Mid-Atlantic, sliding offshore early this weekend. A weak cold front will pass through the region tonight, keeping temperatures below average for Saturday.
WEATHER PATTERN OVERVIEW: Broad upper level flow will continue, and brief clearing this morning will give way to another surface cold front tonight. There is moderate to high confidence a Pacific Northwest ridge will nudge its way eastward enough to give northeast Montana near to above average temperatures by mid week, and no disturbances are expected to move through the area as well.
638 AM EST Fri Jan 24 2025 A cold front moves through today. High pressure then builds in tonight into Saturday before moving offshore Saturday night.
Temps are expected to dip into the low-mid 20s for locations away from the beaches, but given a light/calm wind through the night, apparent temps should remain just above Cold Weather Advisory thresholds (20 degrees). Largely zonal flow is expected aloft, while high pressure is the primary feature at the surface.
531 AM CST Fri Jan 24 2025 (Friday through Saturday) Upper-air pattern this morning shows troughing over our region that will continue to track to the east through the day today and into Saturday. Meanwhile, surface analysis shows a cold front starting to dissect our region from the north, currently sitting at the Louisiana/Arkansas border. Not as cold tonight, with lows ranging from the upper 20s across our eastern zones to the lower 30s across our western zones.
Issued 420 AM CST Fri Jan 24 2025 Today and Tonight: Skies remain clear early this morning as high pressure passes just south of the region. As this high continues east across the Ohio River Valley, a southwest breeze begins this afternoon, with highs around 20 degrees and high-altitude clouds increasing. 850-700mb model charts depict a trough extending south of the Hudson Bay low pressure, co-located with an enhancement in the moisture field, passing between 6 PM and midnight tonight.
554 AM EST Fri Jan 24 2025 A cold front moves through today. High pressure then builds in tonight into Saturday before moving offshore Saturday night.
520 AM CST Fri Jan 24 2025 Below normal temperatures will persist through the short term in the wake of a reinforcing cold front.
414 AM EST Fri Jan 24 2025 A cold frontal moves through today. High pressure then builds in tonight into Saturday before moving offshore Saturday night.
244 PM CST Fri Jan 24 2025 - Cloudy and cooler for the weekend. - Warmer for early and mid week. With high pressure centered off to our east, southerly winds are leading to decent warm air advection across the region. leaving the center of the country under a building ridge.
223 PM EST Fri Jan 24 2025 High pressure will weaken as the air mass gradually modifies through the weekend.
A weak convergence band will move in from the east overnight as a negatively tilted trough digs into the region. This trough will allow very cold temperatures along with breezy northeasterly winds over most of the region, with mountain basins seeing temperatures fall below zero.
1127 AM CST Fri Jan 24 2025 Updated at 1124 AM CST Fri Jan 24 2025 - Warmer temperatures today and Saturday.
1235 PM EST Fri Jan 24 2025 The area of low pressure and frontal boundary that has been lingering over the area the past few days will gradually move eastward into the western Atlantic through the day. Interaction between this front moving into the western Atlantic and strong high pressure over the eastern seaboard will keep a continued predominant northerly wind flow over the region for the next few days. The upper level troughing that has been lingering over the eastern half of the U. High pressure also moves over the southeast U.
235 PM EST Fri Jan 24 2025 A weak cold front moves through the area today, bringing snow flurries to portions of the area. High pressure builds in over the region throughout the weekend with moderating temperatures and dry conditions expected.
1137 AM CST Fri Jan 24 2025 - Much milder with warmer downslope southwest breezes Friday. - Another cold front Friday night will bring north winds and cooler temperatures again Saturday.
CMiller Issued 420 AM CST Fri Jan 24 2025 Today and Tonight: Skies remain clear early this morning as high pressure passes just south of the region. As this high continues east across the Ohio River Valley, a southwest breeze begins this afternoon, with highs around 20 degrees and high-altitude clouds increasing. 850-700mb model charts depict a trough extending south of the Hudson Bay low pressure, co-located with an enhancement in the moisture field, passing between 6 PM and midnight tonight.
(Tonight through Saturday night) High pressure will dominate the forecast tonight through Saturday. Mostly clear skies will bring our lows back into the 30s tonight; however, freezing temperatures are not expected for South Texas. Temperatures for Saturday will warm back into the upper 60s to mid 70s as high pressure shifts east and brings onshore flow back to the area.
Low confidence exists in coverage and intensity as forecast data suggests plenty of dry air in the low levels. This will result in a backing wind becoming more southwesterly but will do little in terms of warm air advection as upper level troughing pulls increasingly colder air over the region with 850mb temps falling to near -20C.
(Remainder of today and tonight) There have been no significant changes to the forecast for the remainder of the afternoon since the update earlier this morning, with gusty WNW winds expected to diminish shortly before sunrise as a low-level ridge axis translates eastward into the TN Valley. With dewpoints predicted to be in the m-u teens and only a few/thin high-level clouds possible in an increasingly zonal flow regime aloft, we have indicated lows in the 15-20F range with some development of freezing fog possible in our normally fog-prone locations (particularly the larger valleys in northeast AL).
High temperatures are forecast to top into the lower to mid 40s. Upper level ridge building offshore with dry northeasterly flow aloft beginning later today.
325 PM EST Fri Jan 24 2025 High pressure will build east of the area overnight.
252 PM EST Fri Jan 24 2025 High pressure will expand across much of the southeastern United States by Saturday morning, then move over the Atlantic Ocean on Saturday. An area of high overcast clouds extends roughly from the US-1 corridor to the coast, while diurnal cumulus have resulted in partly to mostly cloudy skies west of the high clouds. The cloud cover is expected to dissipate this evening as the high slowly pushes east into Georgia through the night. At the sfc, high pressure will slide over central NC before moving offshore by Saturday evening. The airmass associated with this high will remain dry and chilly, with highs only reaching the lower to mid 40s Saturday afternoon.
- Cooler, more pleasant conditions are expected to continue through the weekend.
Ongoing storms rolling off the High Plains will continue into northern KS, likely diminishing by the time they reach our area. As the upper-level ridge axis starts to shift east, southerly/southeasterly flow is expected to return to the area by this afternoon. High temperatures will remain below normal with highs in the low to mid 80s. Low-level upslope flow will help to initiate storms off the High Plains this afternoon to evening.
351 AM EDT Sat Aug 2 2025 Cooler and dry weather will persist through the weekend. KEY MESSAGES: - Cool and dry conditions prevail today --------------------------------------------------------------- Dry and quiet weather is expected today due to high pressure. KEY MESSAGES: - Quiet and dry conditions continue into Sunday - Rocky Mountain wildfire smoke may linger ---------------------------------------------------------------- Confidence remains high that dry and quiet weather will likely continue into Sunday under high pressure. Hazy conditions from Rocky Mountain wildfires, which have affected the Great Plains, may reach the region late Sunday morning with the progression of a weak trough.
Sfc ridging will be directly overhead through Sunday as we will remain downstream of a lower amplitude upper ridge. We will still be under the ridge axis, but the subsidence weakens some as a result.
Wildfire smoke will be slow to move out of the region, even as the high pressure moves out into the Great Lakes. An upper low will transition over the Northern Plains tonight into Sunday.
221 AM CDT Sat Aug 2 2025 - High pressure will bring cooler and normal temperatures and comfortable humidity levels this weekend.
The overall synoptic scenario will be defined by a broad high pressure system expanding over the NE CONUS, while a mid/upper level trough/low complex pushes an associated sfc boundary into the Florida panhandle today. Meanwhile, high pressure remains in control of the rest of the Florida peninsula, keeping a generally seasonal weather pattern across SoFlo through the rest of the weekend.
1253 AM EDT Sat Aug 2 2025 - Cooler and less humid conditions this weekend.
It looks like another round of showers and thunderstorms will move across the area this afternoon and evening with the potential for marginal severe winds south of the Highway 200.
ostensibly a cold front, though there isn't really a cold airmass ready to push in behind it, but moving too much to be a full-out stationary front.
105 AM EDT Sat Aug 2 2025 Cooler and dry weather will persist through the weekend.
Rest of South Florida should remain dry tonight with light winds as high pressure remains over the region. At the upper levels a trough is digging in the eastern US, while upper level high pressure remains over FL and the Gulf. The heat will continue to be the story today as well, as afternoon high temps will once again reach the lower 90s across the metro and middle 90s over inland South FL.
The high temperature forecast may be a bit trickier than it appears given the "cold" front placement and potentially different initiation times of showers and storms across the southern vs northern portions of the area. For now have most everyone in the low to mid 90s, but could easily see the far northern areas a few degrees cooler if convection kicks off earlier.
With a mix of clouds (more to the east), high temps to close out the week should range from the low/mid 80s higher elevations and east, to mid/upper 80s west.
(Today and tonight) An upper-level ridge is centered just off the FL West Coast and continues slowly retrograding westward as a longwave trough axis propagates through the NE. At the base of this trough, a weak frontal boundary is sinking at a snail's pace into N Florida before coming to a halt altogether this weekend just north of our area.
A building upper trough over the eastern CONUS will nudge a front southward through the area over the weekend, bringing more seasonable conditions to much of the area.
Current temperatures across our island communities are reporting in the lower to mid 80s with dewpoints still in the mid to upper 70s.
203 AM EDT Sat Aug 2 2025 High pressure builds over the water today. A weak trough of low pressure crosses the area Saturday night, followed by a cold front approaching later Sunday.
- Much warmer on Sunday with diurnally driven thunderstorms possible Sunday afternoon and evening. Large-scale models are more bullish with the latter (albeit with different timing) indicating upper waves propagating around high pressure over the Desert Southwest and an LLJ core just west of the TX/NM border. Weak easterly surface flow will gradually turn SE this afternoon keeping temperatures in the low 90s with higher cloud cover. The aforementioned upper ridge will provide sufficient capping and prevent most storm development for a majority of the day. The next reasonable chance of storms will occur later this evening as another upper trough/LLJ tracks across portions of the area.
(Today through Sunday) Broad 500mb troughing and a surface front will exist across the Gulf region over the weekend.
Extended stretch of dry and stable conditions through the upcoming weekend governed by a sprawling area of high pressure. This ensures VFR conditions through the taf period with limited cloud development and light winds with some variability at times as the high drifts through. Decreasing northeasterly gradient winds and low cloud fraction allow for sufficient nocturnal radiation cooling, bringing overnight lows down into the low to mid 50s. A bit warmer on Saturday (highs near 80F) as the airmass gradually moderates into the back-half of the weekend. Precipitation-free weather persists as a low-level anticyclone builds eastward, into Lower Michigan. Sunday ushers in a return to near-normal readings (highs in the lower 80s) as surface ridging starts to break down, flipping light winds southeasterly. Temperatures eventually trend a bit warmer than average, back into the mid 80s for weekday highs.
- Below average temperatures are expected to continue through the rest of the weekend, with highs mainly in the lower 70s to lower 80s and lows in the lower 50s to lower 60s. Weak ridging and stagnant flow aloft will keep most of western and central dry through the day. The upper level ridge will break down a bit tonight, leaving most of our area in a split flow regime aloft.
On the periphery of the high we have mild and dry NE winds in the Ohio Valley, maintaining fresh and cool (by the standards of this summer thus far) conditions.
- Ridging shifts westward into the Four Corners during the upcoming week, bringing increased heat, and drier air at the surface. The ridge that has been sitting across the central US, which has given us a feed of monsoon moisture will be finally shifting west the next couple days.
200 AM EDT Sat Aug 2 2025 High pressure will remain overhead through the weekend and much of the upcoming week.
321 AM CDT Sat Aug 2 2025 - High pressure will bring cooler than normal temperatures and comfortable humidity levels this weekend.
213 AM EDT Sat Aug 2 2025 High pressure remains in control through midweek before a frontal system approaches toward week's end. High pressure continues to build into the area from the west with flow becoming light and variable for much of the area this morning. A much drier and cooler airmass is associated with this high pressure system. The mostly clear, dry, and relatively calm conditions will persist through much of the short term forecast as high pressure continues to shift into the area this weekend.
133 AM EDT Sat Aug 2 2025 * After a notably warm and wet July, August begins with a cooler and dry stretch of weather.
Scattered showers are expected again this afternoon and evening, the convection will fire off the higher terrain. Sunday, high pressure remains over southern Arizona as a ridge axis sets up over the CWA.
Issued 403 AM CDT Sat Aug 2 2025 Today and Tonight: Quiet weather will persist through Sunday under high pressure.
722 AM EDT Sat Aug 2 2025 High pressure remains in control through midweek before a frontal system approaches toward week's end. High pressure continues to build into the area from the west with flow becoming light and variable for much of the area this morning. A much drier and cooler airmass is associated with this high pressure system. The mostly clear, dry, and relatively calm conditions will persist through much of the short term forecast as high pressure continues to shift into the area this weekend.
645 AM EDT Sat Aug 2 2025 High pressure builds over the water today. A weak trough of low pressure crosses the area Saturday night, followed by a cold front approaching later Sunday.
635 AM CDT Sat Aug 2 2025 - High pressure will bring cooler than normal temperatures and comfortable humidity levels this weekend.
With early start to convection and lingering cloud cover, adjusted max temps to range generally in the lower 90s, with some sun still expected into the afternoon.
Clear skies this morning across southeast Arizona as the mid/upper level high is located over our forecast area. This high will continue to bring well above normal temperatures and extreme heat for much of southeast Arizona this weekend. Still enough residual moisture recycling under the high today for isolated shower and thunderstorm activity south and east of Tucson. However, with the high overhead, that will limit updraft growth, thus any shower/thunderstorm activity will be on the weaker side with just some brief downpours and locally gusty winds.
High pressure continues to remains across the Desert Southwest this morning and will stay in place through the weekend. The high starts to shift to the east early in the new week, which may allow for some moisture to return towards the middle of the week. With high pressure continuing to sit over the region, we will continue to see things drying out. The high looks to push to the east and over New Mexico early in the week, with the potential for some moisture to advect back into our area. Another issue will be the heat combined with increasing moisture and we may see some of the hottest conditions of the summer, especially across the lower elevations of Yavapai County.
Cronce Issued 403 AM CDT Sat Aug 2 2025 Today and Tonight: Quiet weather will persist through Sunday under high pressure.
Highs today will be around the norm for this time of year, as they range from the upper 80s to the lower 90s. A building upper trough over the eastern CONUS will nudge a front southward through the area over the weekend, bringing more seasonable conditions to much of the area.
939 AM EDT Sat Aug 2 2025 High pressure builds to the south today. A weak trough of low pressure crosses the area tonight, followed by a cold front approaching later Sunday.
638 AM EDT Sat Aug 2 2025 High pressure will remain overhead through the weekend and much of the upcoming week.
632 AM CDT Sat Aug 2 2025 - Stagnant weather pattern remains in place with a strong high pressure over the region trapping smoke at the surface. - A Rex blocking pattern sets up over the Northland leading to off and on rain and thunderstorm chances through the work week.
N/NE sfc flow will continue to supply dry LL air into the area through today, but as the high drifts to the E into the interior NE CONUS by Sunday, some return flow will begin to emerge once again.
257 PM EDT Sat Aug 2 2025 Cooler and mainly dry conditions through the weekend. A seasonably cool weekend across the region as high pressure gradually traverses north of the region. Highs today will top out in the mid 70s to 80 for the lowlands, with mid 60s to low 70s across the mountains. Sunday will feature warmer temperatures (~ 5 degrees) amid a FEW/SCT fair weather Cu field.
For the rest of the area, we'll remain dry with highs in the low to mid 80s.
Surface dewpoints vary from the low 40s to low 50s across the western CWA to the upper 50s to lower 60s across the eastern CWA. The question will be how long will they survive coming off of the higher terrain? ML CAPE by 21Z Sunday is in the area of 1500-2000 J/kg with CIN minimized across the higher elevations.
(This evening through Sunday) Surface analysis early this afternoon depicts a cold front draped along the Northern Gulf coast. This activity is expected to expand north through the afternoon hours as several bouts of H85-H5 vorticity rotate around the base of an upper trough centered across the Great Lakes region.
Upper troughing will be in place over the eastern US for much of the next five days or so.
Rain chances continue through much of the forecast period as a broad mid/upper trough lingers over the eastern U. Regarding Sunday PoPs, the inverted trough shifts west some, and SELY H85 flow becomes more pronounced over the CWA.
