SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0344 PM CST Tue Feb 24 2026 Valid 261200Z - 041200Z ...Synopsis... Mid-level flow will remain amplified over CONUS through nearly all of the extended forecast period before an upper-level pattern change early next week. The current pattern will prevail through Day 6/Sunday, aiding in continued Elevated fire weather conditions in the Central and Southern Plains. Day 7/Monday - Day 8/Tuesday, a transition to southwesterly flow aloft in the Southwest and Southern Plains will evolve as a closed low develops off the western US coast. Surface troughing and enhanced southerly surface flow may bring modest Gulf moisture to the Plains region, limiting broader fire weather concerns in the extended forecast period. ...Day 3/Thursday - South Central Texas... As the surface low continues to shift south towards the Texas Gulf Coast, a weak dry cold front will push into South Central Texas through the afternoon bringing dry and breezy northerly surface winds of 15-20 mph. With daytime RH values of 15-20%, and above normal surface temperatures across the area on Day 2/Wednesday, finer fuels will likely have dried out leading to potential receptiveness to fire. 40% Critical probabilities have been maintained. Beneath strong mid-level flow, tight surface pressure gradients across central Wyoming may support strong downslope winds and low RH in the lee of the Laramie Range into far western Nebraska on Day 3/Thursday and Day 4/Friday. However, with the potential for light precipitation across the area on Day 2/Wednesday, and model uncertainties in overlap of stronger winds and low RH, fire weather highlights have been withheld for now. On Day 5/Saturday, mid-level flow slowly shifts zonal as surface troughing pushes cooler air into the Central US while southerly flow along the TX Gulf Coast advects moisture northward into the Southern Plains. Some model spread exists past Day 6/Sunday in the extent of surface moisture return, though given the agreement in the overall resulting pattern, fire weather concerns appear fairly minimal and localized through the extended forecast period. ..Elizalde-Garcia/Barnes.. 02/24/2026 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0348 PM CST Mon Feb 23 2026 Valid 251200Z - 031200Z ...Synopsis... Mid-level flow will remain amplified over CONUS through the extended forecast period. The predominant pattern will feature troughing over the eastern US while strong mid-level flow continues across the central US. Amplified ridging over the West will support strong downslope flow and lee troughing over the Southern and Central High Plains. This pattern will aid continued Elevated to Critical fire weather conditions through the forecast period. ...Day 3/Wednesday - Southern Plains and Southeastern Colorado... Fire weather conditions are expected to continue as a lee surface low moves southeast across the Central Plains amid northwesterly flow. Strong mid-level flow aloft will support broad downslope northwesterly winds of 10-20 mph and RH values below 20% , so 40% Critical probabilities have been maintained. 70% Critical probabilities have been introduced where a localized area in southeastern NM may experience stronger northwesterly downslope surface winds of 20-30 mph atop dry, receptive fuels. ...Day 4/Thursday - South Central Texas... As the surface low continues to shift south towards the Texas Gulf Coast, a weak dry cold front will pass through South Central Texas late morning/afternoon bringing dry and breezy northerly surface winds. With low humidity and warm surface temperatures across the area on Day 3/Wednesday, fine fuels will likely have dried out some, leading to potential receptiveness to fire. 40% Critical probabilities have been introduced to account for fire weather concerns. Beneath strong mid-level flow, tight surface pressure gradients across central Wyoming may support strong downslope winds and low RH in the lee of the Laramie Range into far western Nebraska on Day 4/Thursday and Day 5/Friday. However, with the potential for light rainfall across the area on Day 3/Wednesday, fire weather highlights have been withheld for now. Model spread increases on Day 5/Friday through the remainder of the forecast period regarding the overlap of dry and windy conditions. Nonetheless, as the mid/upper-level pattern persists, fire weather conditions will likely continue across portions of the Central and Southern High Plains into the weekend. ..Elizalde-Garcia/Thornton.. 02/23/2026 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0117 PM CST Mon Feb 23 2026 Valid 241200Z - 251200Z ...CRITICAL FIRE WEATHER AREA FOR SOUTHEAST COLORADO INTO PARTS OF THE SOUTHERN HIGH PLAINS... ...20z Update... Critical fire weather highlights have been expanded farther north into southeastern CO and farther east into the Rolling Plains of TX. Recent model guidance has increased probabilities of combined (west-southwesterly) wind speeds greater than 20 mph and RH values less than 15% within the Critical area. These conditions atop dry and recently receptive fuels will support ignition and fire spread throughout the afternoon on Tuesday. Southeast WY into western NE will experience very strong downslope winds of 35-45 mph (locally stronger gusts up to 70 mph) late Tuesday morning into the overnight hours. Given recent snowfall, expected cloud cover, and minimum RH of 30-40%, Elevated fire highlights have been withheld. See the previous discussion for more information. ..Elizalde-Garcia/Thornton.. 02/23/2026 .PREV DISCUSSION... /ISSUED 0103 AM CST Mon Feb 23 2026/ ...Synopsis... ...Southeast Colorado into southern High Plains... Mid-level flow will increase across the central and southern Rockies on Tuesday. A modestly deep lee cyclone will promote downslope winds from southeast Colorado into northeastern/east-central New Mexico. Winds of 20-25 mph appear possible, especially within the more terrain-favored locations. RH of 10-15% will also be common. Dry fuels will continue to support ignition and spread in this environment. Critical fire weather is most likely in southeast Colorado into eastern New Mexico and parts of the Texas South Plains. Farther south, weaker winds will keep fire weather concerns Elevated within the Trans-Pecos/Big Bend regions. ...Southern Plains into the Ozarks... Ahead of the surface front, stout, gusty southerly/southwesterly winds are expected from the Texas Rolling Plains into much of Oklahoma and Ozarks. Mid/high clouds will be increasingly probable with northeastward extent. However, the dry return flow will allow RH of fall into the 15-25% range. Winds of 15-20 mph will occur during the afternoon. Strong flow within the lowest 2 km will also promote stronger gusts. Most areas have not observed precipitation recently and fuels remain receptive. ...Southeast Wyoming into the Front Range... Given the pressure gradient across the terrain, dry downslope winds will be possible in these areas. Recent precipitation has mitigated fuels dryness in the short term. Furthermore, mid/upper clouds appear likely which will create some uncertainty in how low RH will fall. Locally elevated conditions do appear possible where fuels are drier as pockets of stronger wind are possible. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC 1930Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0105 PM CST Mon Feb 23 2026 Valid 251200Z - 261200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms will be possible late Wednesday night into early Thursday morning across portions of the Ozarks east into the Tennessee Valley. ...Synopsis and Discussion... A shortwave trough is forecast to progress quickly from the Pacific Northwest in the central Plains/Mid MO Valley on Wednesday, moving within the broadly cyclonic upper flow expected to be in place across the CONUS. Deepening surface lee troughing is anticipated ahead of this wave, with cyclogenesis eventually yielding a low that progresses across the TX Panhandle during the evening and along the Red River overnight. A moistening warm sector will precede this surface low and its parent shortwave, with mid 50s dewpoints reaching across much of eastern OK and southern/central AR by early Thursday morning. 60s dewpoints will likely remain confined farther south along the TX Coast, with warm temperatures aloft precluding deep convection throughout the warm sector. However, strengthening low to mid-level flow is anticipated throughout the warm sector, resulting in moderate to strong warm-air advection across the frontal zone extending northeastward from the Red River surface low. Showers and a few thunderstorms are possible across the Mid-South and TN Valley as limited but sufficient buoyancy develops amid the moistening low to mid-levels and cool temperatures aloft. A few thunderstorms are also possible immediately ahead of a weak triple point low farther west in the vicinity of the confluence of the MS and OH rivers. ..Mosier.. 02/23/2026 Read more

Thunderstorms are not expected across the US on Tuesday. ...Synopsis and Discussion... Moderate northwesterly flow aloft is forecast to extend across the majority of the CONUS early Tuesday. Several shortwave troughs are expected to move within the this northwesterly flow, including one forecast to move across the Upper Midwest, Upper Great Lakes, and adjacent northwestern Ontario. A deepening lee trough, and likely lee low development, will help tighten the surface pressure gradient across the Plains. Resulting southerly flow across the Southern Plains will encourage some modest low-level moisture return is anticipated late Tuesday through Wednesday morning across the TX Gulf Coast. However, the previously mentioned shortwave is expected to remain displaced well north of this low-level moisture and any associated buoyancy, precluding thunderstorm developing across the CONUS. A shortwave trough will also move into the Pacific Northwest early Wednesday morning. Cool and moist profiles are expected to be in place Tuesday morning, with some mid-level drying anticipated across the region throughout the day ahead of this wave. Some additional cooling/moistening is possible along the WA coast early morning as the wave moves through. However, stable conditions will prevail throughout the period, with no lightning anticipated. ..Mosier.. 02/23/2026 Read more

Elevated highlights have been expanded to cover the FL Panhandle, Central Gulf Coast, and southeastern LA. Despite some areas receiving recent wetting rainfall, multiple new starts yesterday afternoon in Louisiana heighten concerns for spotty fuel receptiveness. Given the entire Central Gulf Coast may see RH values below 35% and sustained northwesterly winds of 10-20 mph, Elevated fire weather conditions are expected. Parts of Southern Florida are already experiencing Critical fire weather conditions this morning. RH values are expected to drop to 25-35% and sustained northwesterly surface winds increasing to 10-15 mph (locally higher gusts 20-30 mph) this afternoon. See the previous discussion for more information. ..Garcia/Thornton.. 02/23/2026 .PREV DISCUSSION... /ISSUED 0101 AM CST Mon Feb 23 2026/ ...Synopsis... ...Florida... A dry airmass will move down the peninsula today in the wake of a cold front. Recent precipitation has mitigated some fuel receptiveness, particularly in North/Central Florida. However, South Florida has remained rather dry and fuels will be receptive to ignitions/spread. Winds will generally be stronger in the morning, before slowly weakening into the afternoon/evening. During the afternoon, winds of 10-15 mph can be expected. Given persistent surface winds down the peninsula, RH may be near Elevated criteria even early this morning. RH values by afternoon will be 25-35% in the north with around 20% in the south. Critical fire weather is expected in South Florida with elevated to locally critical elsewhere. ...Southern High Plains... Winds of 15-20 mph and RH of 10-20% are possible during the afternoon. Lack of recent rainfall has continued to allow fuels to dry. Elevated fire weather can be expected. ...Central Gulf Coast... Dry offshore flow will continue today. Despite RH of 20-25% in some areas, winds will generally be too light to promote more than locally elevated concerns. ...Southeast Wyoming... It is possible that locally elevated conditions will occur today as winds increase due to a modest lee trough and increasing mid-level winds.

MD 0117 CONCERNING BLIZZARD FOR PARTS OF THE NORTHEAST AND SOUTHERN NEW ENGLAND
Mesoscale Discussion 0117 NWS Storm Prediction Center Norman OK 0413 AM CST Mon Feb 23 2026 Areas affected...parts of the Northeast and southern New England Concerning...Blizzard Valid 231013Z - 231515Z SUMMARY...Very heavy snowfall rates of 2-3 inches per hour and widespread blizzard conditions should persist across Long Island and southern New England through 10 AM EST. DISCUSSION...Classic bomb cyclone/nor'easter off the Northeast coast will slow its deepening over the next few hours as it tracks northeastward off the southern New England coast through midday. As this occurs, multiple bands of very heavy snow from NJ to southeast MA should consolidate into one primary band across Long Island to eastern MA through mid-morning. Extremely enlarged low-level hodographs are indicative of the impressive warm conveyor north of the cyclone. In addition, very high KDP values detected within and somewhat below the dendritic growth zone amid base reflectivity values around 35 dBZ all point to highly prolific snowfall rates of 2-3 in/hr. From eastern Long Island through eastern MA, this appears likely to persist for several hours. Measured severe wind gusts should persist in this same region, supporting widespread blizzard conditions. The aforementioned slowing of cyclogenesis and northeastward track will eventually yield a more progressive tapering of very heavy snowfall rates from the southwest towards late morning. ..Grams.. 02/23/2026 ...Please see www.spc.noaa.gov for graphic product...

Thunderstorms are not expected today or tonight. ...Discussion... Convective potential will be virtually nil today. While isolated lightning flashes were noted overnight east of Long Island and near coastal southern New England, lightning-conducive thermodynamic profiles, in the northwest quadrant of the deep offshore cyclone, will continue to quickly diminish and shift away from the coast. In the Pacific Northwest, a few lightning flashes occurred overnight in coastal Washington, and a sliver of weak buoyancy was observed in the 12z UIL/Quillayute, WA sounding. However, a trend toward shortwave ridging and less-lightning-conducive thermodynamic profiles should effectively end such thunderstorm potential. ..Guyer/Grams.. 02/23/2026 Read more
