309 AM MST Mon Feb 24 2025 - 2 - 3 degrees warmer today than yesterday.
(Today and tonight) An upper level low will track into the PacNW today, with the best chances for rain occuring well to our north. Opted to take a mix of yesterday's temps and blend it with the NBM for today to get slightly warmer temperatures for areas near the Central Coast.
557 AM CST Mon Feb 24 2025 (Monday through Tuesday) Temperatures at 3 & 4 am this morning are in the low to mid 40s along and south of I-20, with 46 in Lufkin for the warmest. The coldest by far was DeQueen freezing last hour, but up two now with the fog. Just a couple or few upper 30s as we continue to modify in the wake of Canadian high pressure. The winds tomorrow will prevail from the S/SW with warmer temps in the low to mid 70s.
605 AM EST Mon Feb 24 2025 High pressure remains in control of the weather today into tonight.
* A cooler and more unsettled weather pattern returns this weekend through the first week of March. Ridge winds in the Tahoe Basin will gust up to 90 mph while wind prone locations will see gusts up to 50 mph. For our friends in Mono county, wind gusts won't be nearly as high (up to 65 mph along ridgetops).
Behind the trough, drier air will move into the area.
611 AM EST Mon Feb 24 2025 (Today and tonight) Rain will gradually taper off from west to east today as a weak area of low pressure passes south of the region. However, cloud cover will linger for much of the day as the upper level trough axis moves overhead.
544 AM EST Mon Feb 24 2025 A relatively zonal flow is expected through the middle of this week, with a weak cold front moving across the region Tuesday.
(Monday through Tuesday) Temperatures at 3 & 4 am this morning are in the low to mid 40s along and south of I-20, with 46 in Lufkin for the warmest. The coldest by far was DeQueen freezing last hour, but up two now with the fog. Just a couple or few upper 30s as we continue to modify in the wake of Canadian high pressure. The winds tomorrow will prevail from the S/SW with warmer temps in the low to mid 70s.
515 AM CST Mon Feb 24 2025 - Mostly warmer than average temperatures is expected through this forecast period. (Today through Tuesday night) With a trough off to the southeast of the CWA, the Panhandles will be under northwesterly flow aloft today. The cyclonic flow around the low will introduce northerly winds to progressively more of the Panhandles through the day which will help keep temperatures somewhat in check. A cold front will move in from the north Tuesday night and breezy northerly winds will accompany it.
Elsewhere daytime temperatures will peak into the low/mid 60s. Overnight lows will drop into the low 40s areawide.
Strong high pressure will build over the region through Tuesday, with afternoon high temperatures climbing 10 to 15 degrees above normal. Low amplitude ridge with anomalous heights for late-February will remain in place over the next couple days, keeping regional temperatures well above normal with just some passing high clouds mainly across our northern-most horizons.
1 to 2 inches of new snow possible at the highest elevations.
534 AM EST Mon Feb 24 2025 Quiet conditions continue today along with warmer temperatures. A weak low pressure system brings a mix of rain and some wet snow showers to the region late Monday night into Tuesday.
515 AM CST Mon Feb 24 2025 Updated at 513 AM CST Mon Feb 24 2025 - Even warmer today under full sun. (Today and tonight) Height rises in NW flow were well in hand this morning on the heels of a compact upper low shifting southeast across the Hill Country. Barring a few streaks of cirrus today, net subsidence with a dearth of moisture will keep skies sunny all the while lee troughing keeps downslope winds in check. Given NBM's underperformance with highs lately and its moist dewpoint bias evident this morning, opted to run with the warmer and driest model solutions for this pattern.
906 AM EST Mon Feb 24 2025 Weakening high pressure shifting offshore will continue to foster a warmup over the next few days.
528 AM CST Mon Feb 24 2025 (Today through Tuesday) A 500mb trough swings off the Texas coast today, with high pressure building at the surface, maintaining very comfortable conditions through the short term period. A slightly cooler day in the upper 60s to near 70 is expected on the island.
(Today and tonight) Rain will gradually taper off from west to east today as a weak area of low pressure passes south of the region. However, cloud cover will linger for much of the day as the upper level trough axis moves overhead.
Lookout and Lolo passes have the highest snowfall range, from 6 to 12 inches for this system.
627 AM EST Mon Feb 24 2025 Weakening high pressure shifting offshore will continue to foster a warmup over the next few days.
Temperatures on Tuesday will be a touch cooler with the lack of downsloping winds. Upper level ridging will move off east of the area as flow aloft becomes more zonal.
A low pressure system in the Gulf will continue to move towards south Florida. Rain showers will continue throughout the afternoon into the evening with some isolated showers still possible tomorrow morning as extra moisture wraps around the low. Conditions begin to clear tomorrow afternoon as high pressure builds back in and drier air moves over the region.
1228 PM EST Mon Feb 24 2025 Weakening high pressure shifting offshore will continue to foster a warmup over the next few days.
A thermal gradient between waves of rain has resulted in a trough extending across the southern half of Florida and the low-level downslope flow behind its leading edge has kept most of the convection well to our south with a drying trend across much of south Florida. The next wave of rain is being forced along the synoptic warm front and along the cold front as well.
Temperatures have risen into the lower to middle 60s for most areas, with winds remaining mostly less than 10 mph. Low temperatures tonight remain pretty mild, well above normal in the lower 30s. And then another fantastic day on Tuesday, with high temperatures again in the lower to middle 60s, although southwesterly winds will be a little more breezy tomorrow at 10 to 20 mph.
1254 PM EST Mon Feb 24 2025 High pressure remains in control of the weather today into tonight.
Pattern/synopsis: An initial, weak cold front has exited eastward, and weak cold advection is underway at 850mb. A secondary cold front now north of Superior will get dragged into eastern upper MI Tuesday morning. Forecast: A cooler and more moist low-level airmass looms to our nw and n, with a widespread low overcast. A variety of light p-types are possible, with weak lake instability generating snow and/or rain showers, while more laminar DZ/FZDZ also emerging at times (especially over the higher terrain of northern lower). Lows tonight near 30f to the low 30s.
243 PM CST Mon Feb 24 2025 Tonight through next Monday: Sfc ridging will begin to filter into the region tonight, clearing any lingering clouds.
Highs are forecast to warm to the low to mid 70s under sunny skies Tuesday afternoon with light northwesterly winds.
322 PM EST Mon Feb 24 2025 Breezy conditions expected across the region with a passing trough over the Great Lakes. KEY MESSAGES: - Breezy conditions expected into the late evening - Above average temperatures expected ------------------------------------------------------------------- A passing trough over the Great Lakes will continue to increase cloud coverage from the north and gusty conditions due to an enhanced gradient wind.
(Rest of Today) More seasonably mild conditions are expected today across the mid TN Valley, as weak high pressure remains in place over much of the region. Highs later today actually look to climb into the lower 60s/near 60F for most spots, which is near or slightly above seasonal trends for this time of the yr.
5 over the remainder of the Lower Keys, with up to 0. Storm structure has been quite interesting, with a number of mesocyclones embedded in the larger-scale stratiform precipitation. The rotational aspect of these embedded cells is consistent with KBYX VWP imagery, with substantial veering throughout the depth of the lower and middle troposphere aiding in convective organization.
Under these clear skies we're getting very effective mixing of the atmosphere and the higher winds and drier air in mid levels are occasionally being brought down to the surface and several observations are reporting occasional gusts over 10 mph and RH values dropping around 30%. These clouds will help keep temperatures much warmer than last night.
Despite the cloud cover today, temps are reaching the low to mid 60s over most areas.
0", and the Lower Keys between 1. All available mesoscale guidance certainly had a tough time resolving the evolution of this high- impact rain event this morning, and we are still scratching our heads a bit at the source for these near-record rainfall amounts. Rainfall trends, particularly over the Lower Keys, have been downward over the past couple of hours, with visible satellite imagery even indicating some breaks in cloud cover to the west. Mesoscale analysis places an amplified, positively tilted trough in the Gulf, with its axis extending from the Yucatan Peninsula northeastward to the Florida Panhandle.
231 PM EST Mon Feb 24 2025 Dry high pressure remains over the region through midweek.
1200 PM CST Mon Feb 24 2025 - Mostly warmer than average temperatures is expected through this forecast period. (Today through Tuesday night) With a trough off to the southeast of the CWA, the Panhandles will be under northwesterly flow aloft today. The cyclonic flow around the low will introduce northerly winds to progressively more of the Panhandles through the day which will help keep temperatures somewhat in check. A cold front will move in from the north Tuesday night and breezy northerly winds will accompany it.
137 PM EST Mon Feb 24 2025 Weak high pressure will linger over the region through tonight.
As the upper-level trough over the Gulf shifts further east, low- level southerly return flow looks to set up across Southern Texas and into the Southeast Tuesday. This southerly flow will advect a warmer air mass to the region.
205 PM EST Mon Feb 24 2025 High pressure will gradually slide offshore today leading to gradually warming temperatures and dry conditions.
1120 AM CST Mon Feb 24 2025 Updated at 1119 AM CST Mon Feb 24 2025 - Even warmer today under full sun. (Today and tonight) Height rises in NW flow were well in hand this morning on the heels of a compact upper low shifting southeast across the Hill Country. Barring a few streaks of cirrus today, net subsidence with a dearth of moisture will keep skies sunny all the while lee troughing keeps downslope winds in check. Given NBM's underperformance with highs lately and its moist dewpoint bias evident this morning, opted to run with the warmer and driest model solutions for this pattern.
1114 AM CST Mon Feb 24 2025 (Today through Tuesday) A 500mb trough swings off the Texas coast today, with high pressure building at the surface, maintaining very comfortable conditions through the short term period. A slightly cooler day in the upper 60s to near 70 is expected on the island.
pdf Low pressure will track east across central FL this afternoon, then off the coast near Melbourne this evening. The low will then track away to the east northeast through the night. Rain showers will still be expected over southern and eastern areas as the low passes through. Drier air wrapping in behind the low, will bring an end to rain to areas further inland and north, along with a decreasing cloud trend. Lows Tonight will be in the mid to upper 40s SE GA, and generally in the lower to mid 50s over NE FL.
(Tonight through Tuesday night) Key Messages: - Dense Fog Advisory will go in effect from midnight tonight through noon Tuesday With that aforementioned trough having cleared the region, warm and quiet conditions will be expected to begin the week.
The low ceilings and fog dissipate and yield VFR conditions by mid Tuesday morning.
1025 AM MST Mon Feb 24 2025 - 2 - 3 degrees warmer today than yesterday.
This will translate to warmer temperatures in the short term, with lows for Tuesday morning in the mid 40s/lower 50s.
* A cooler and more unsettled weather pattern returns this weekend through the first week of March. * A low pressure system moving into the Pacific Northwest has led to increased pressure gradients across the region.
High pressure over the area will flatten this evening ahead of the arrival of a mostly dry cold front tonight into Tuesday. High pressure will return for the remainder of the work week, with a potentially more active pattern developing for the upcoming weekend and beyond.
A little light freezing rain possible in some locations Tuesday morning. Current surface analysis places low/trough dropping through eastern South Dakota, while high remains over the Rockies. Low to moderate chances for light rain will spread through the area, with the potential for a little light freezing rain in the morning over a few locations, though this would be very limited.
635 PM EST Mon Feb 24 2025 Breezy conditions expected across the region with a passing trough over the Great Lakes. KEY MESSAGES: - Breezy conditions expected into the late evening - Above average temperatures expected ------------------------------------------------------------------- A passing trough over the Great Lakes will continue to increase cloud coverage from the north and gusty conditions due to an enhanced gradient wind.
High pressure over the region will allow for temperatures to top out 10 to 15 degrees above normal today and tomorrow.
107 PM PST Mon Feb 24 2025 Weak system brings light showers north of Interstate 80 and breezy south to southwest winds along the higher terrain today.
510 PM CST Mon Feb 24 2025 (Rest of Today) More seasonably mild conditions are expected today across the mid TN Valley, as weak high pressure remains in place over much of the region. Highs later today actually look to climb into the lower 60s/near 60F for most spots, which is near or slightly above seasonal trends for this time of the yr.
Current surface analysis shows low pressure over eastern Ontario, with a weak cold front extending across the upper Midwest and into the Plains, now passing south and east of the forecast area. Lows will be a little cooler in most locations tonight, mid 20s to mid 30s. The next cold front will arrive during the day Tuesday, with another round of gusty winds, especially across far southern portions of northeast WY, far southwest SD, as well as usual areas of northwest into west central SD.
534 PM CST Mon Feb 24 2025 (Tonight through Tuesday night) Key Messages: - Dense Fog Advisory will go in effect from midnight tonight through noon Tuesday With that aforementioned trough having cleared the region, warm and quiet conditions will be expected to begin the week.
A few light showers across portions of the region tonight and tomorrow as a cold front moves thru Nevada, though breezes will be the main weather impact.
640 PM CST Mon Feb 24 2025 Tonight through next Monday: Sfc ridging will begin to filter into the region tonight, clearing any lingering clouds.
While rainfall totals haven't been impressive thus far, ranging from just a quarter to half inch over much of the area, additional rounds of rain are expected tonight and overnight as the low eventually traverses South FL. A thermal gradient between waves of rain has resulted in a trough extending across the southern half of Florida and the low-level downslope flow behind its leading edge has kept most of the convection well to our south with a drying trend across much of south Florida. The next wave of rain is being forced along the synoptic warm front and along the cold front as well.
Heaviest rainfall has been along and near the warm front that has been draped through the Tampa Bay area along I-4 corridor today. 88D radar imagery showing the showers and frontal boundary have started to shift S ahead of the low center that will move ashore tonight. A low pressure system in the Gulf will continue to move towards south Florida. Rain showers will continue throughout the afternoon into the evening with some isolated showers still possible tomorrow morning as extra moisture wraps around the low. Conditions begin to clear tomorrow afternoon as high pressure builds back in and drier air moves over the region.
The actual upper trough axis will shift east of our area by around midnight tonight. At the surface, low pressure currently over the southeastern Gulf will move east across south Florida tonight and then off into the southern Atlantic Ocean by area Tuesday. Lows tonight ranging from the low 40s well inland to the upper 40s along and just south of the I-10 corridor (and some lower 50s along the immediate coast). Highs on Tuesday in the lower 70s for all locations.
800 PM EST Mon Feb 24 2025 Breezy conditions expected across the region with a passing trough over the Great Lakes. ------------------------------------------------------------------- Aside from a minor update to temperatures which are trending slightly warmer than progged this evening (likely due to cloud cover and winds mitigating radiational cooling/decoupling), the forecast remains largely on track. Rain showers (possibly a mix with snow in the ridges and north of I-80) move into the area from the west during pre-dawn hours. The probability of rain increases with a passing trough early Tuesday morning. Precipitation chances will decrease from west to east Tuesday afternoon with increase subsidence with ridge building to our west.
That said, the remainder of the region has snow totals at or less than 6" even at the high end estimates, so will forego another headline for this round. Temperatures overnight tonight are expected to be some 5- 15 degrees above normal, with at or above freezing in many Snake Plain and lower elevations to the south. Near normal temperatures are forecast Tuesday and Tuesday night behind cold frontal passage, with a return to sub-freezing overnight lows.
1230 AM PST Tue Feb 25 2025 High temperatures this afternoon will be around ten degrees cooler than yesterday afternoon.

1122 PM CST Mon Feb 24 2025 (Tonight through Tuesday night) Key Messages: - Dense Fog Advisory will go in effect from midnight tonight through noon Tuesday With that aforementioned trough having cleared the region, warm and quiet conditions will be expected to begin the week.
Today's high temperatures have some overshoot potential, the HRRR is taking afternoon valley temperatures Knoxville and south to 70F, which is a few degrees warmer than the NBM's forecast. Beyond the temperature intrigue, we will cool off tonight, with the high resolution guidance indicating potential for patchy fog tonight. Lows should be similar to this morning's, fairly variable but around frost temperatures or just warmer, maybe a few cool spots scattered about.
1217 AM MST Tue Feb 25 2025 - Cold front Tuesday morning with slightly cooler temperatures and gusty winds.
/86/ Tonight through next Monday: Sfc ridging will begin to filter into the region tonight, clearing any lingering clouds.

A bit cooler temperatures then move in for Wednesday, with highs generally in the 40s to low 50s (still above normal).
Water vapor imagery was indicating a strong upper trof acrs OR and ID, with pre-system baroclinic leaf streaming from CA to acrs WY ATTM. Will side with the 75th percentile as a happy medium of outcomes, but this may be too cool and will allow temps to beat me on the high side if they can.
- Meteorological Overview: A Pacific cold front continues to move from west to east across the CWA this morning. A few scattered snow showers continue tonight, but overall a drying trend begins, as an upper level ridge of high pressure starts to build over the CWA on Wednesday.
(Today through Wednesday) Very quiet weather is anticipated for this short-term, as surface ridging begins to reinforce across the region. Aside from the fog tonight, highs today will range in the low-70s, with highs tomorrow jumping to the mid-70s. Lows tonight will remain on the cool side, with lows generally ranging in the low to mid-40s.
313 AM MST Tue Feb 25 2025 KEY MESSAGES: - Freezing rain and rain is possible today - As thawing conditions occur, rises in local streams and muddy conditions on unpaved roads will continue. Best chance of rain will be in the north and with temperatures near or below zero and still some snow on the ground, freezing rain and icy conditions are possible this morning. For the remainder of the week, an upper ridge will build along the west coast with high pressure over the Rockies/Great Basin. FORECAST CONFIDENCE & DEVIATIONS: Confidence for freezing rain remains low (below 30%) with little to no accumulation.
544 AM CST Tue Feb 25 2025 Updated aviation portion for 12Z TAF issuance - A mix of light snow, drizzle and freezing drizzle could produce hazardous travel late tonight and Wednesday morning. Even though air temperatures may be a little above freezing in central and east central Wisconsin, drizzle may freeze on the pavement that is cold from the below normal temperatures over the last month.

(Today and tonight) Lee troughing resumes today allowing light northerly winds this morning to veer southerly. Thicknesses drop a bit over yesterday as upper ridging flattens, but high temps are still favored to be finish above the NBM with 70s north and lower 80s south.
The lowest confidence in vsbys remains at KPNS where VFR vsbys should prevail with occasional reductions to MVFR possible. The upper trough has moved east of our area with drier northwesterly to westerly flow developing over the area. The remainder of the forecast will be dry and mild with highs in the lower 70s.
Finally, increasing winds and building seas along the Lower Texas Coast will produce a Moderate Risk of rip currents at the local beaches tonight and Wednesday.
