SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1136 AM CDT Mon Mar 24 2025 Valid 241700Z - 251200Z ...Appalachians... An Elevated risk area has been added to parts of the central Appalachians where westerly downslope winds are expected to increase to near 15 mph this afternoon with RH reductions into the 20-30% range. Lingering clouds are expected to clear by mid-afternoon as a surface trough traverses the Appalachians. Given recent fire activity over the past few days, the increasing winds and reduced RH should promote at least a low-end fire weather concern. ...Central/Southern Plains... The Elevated risk area across OK/KS has been expanded based on morning surface observations which show winds already increasing to near 15 mph and RH falling into the upper 20s. Localized fire weather conditions remain possible across northwest KS into adjacent areas of CO and NE, but confidence in RH reductions remains limited given increasing cloud cover. ..Moore.. 03/24/2025 .PREV DISCUSSION... /ISSUED 0202 AM CDT Mon Mar 24 2025/ ...Synopsis... Mid-level flow will gradually amplify through the forecast period as shortwave ridging builds to the west, and a broad trough deepens to the east. The primary cold front will continue offshore over the Atlantic and Gulf Coast as northwesterly flow aloft will overspread much of the central US. A weak secondary surface low and trailing front will move over the Plains States supporting gusty winds and some localized fire-weather risk. ...OK and KS... A weak surface low over the central US will move southeast ahead of a second cold front moving across the northern and central Plains. Ahead of the front, veered low-level flow will gradually increase through the day across parts of OK and KS. Southwesterly gusts of 10-20 mph will occur with low afternoon RH around 25%. The dry and breezy conditions will overlap with very dry fuels supporting a few hours of elevated fire-weather conditions. Behind the secondary front across northern/central KS, gusty northwest winds are also possible for a few hours this afternoon. However, a cooler air mass will favor higher RH atop fuels that are less receptive. Some localized fire-weather concerns may develop, but more widespread concerns are not expected. ...Appalachians... In the wake of the first cold front, a few hours of gusty westerly winds are possible across the central and southern Appalachians. While light rain will likely temper fuels and RH minimums, the strong winds may still briefly overlap with RH below 30% during the afternoon across western VA and NC. This could support locally elevated fire-weather conditions given the dry fuels and recent fire activity. ...Please see www.spc.noaa.gov/fire for graphic product... Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1108 AM CDT Mon Mar 24 2025 Valid 241630Z - 251200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON ALONG THE GULF COAST FROM SOUTHEAST LOUISIANA INTO THE FLORIDA PANHANDLE.... ...SUMMARY... Severe thunderstorms are possible today from southern Louisiana eastward to the Florida Panhandle and far southern Georgia. ...Gulf Coast... Clusters of thunderstorms have been affecting parts of southern LA/MS/AL and the FL Panhandle this morning. The effective outflow boundary currently extends from the Delta region of southeast LA eastward across the Gulf near-shore waters into the FL Panhandle, and is pushing slowly southward. This will significantly limit the area of surface-based instability through the afternoon. Nevertheless, a strong storm or two will remain possible in vicinity of the boundary, with locally damaging winds or hail being the main concerns. ..Hart/Mosier.. 03/24/2025 Read more

Severe thunderstorms are possible today from southern Louisiana eastward to the Florida Panhandle and far southern Georgia. ...Gulf Coast from southeast Louisiana to Florida Panhandle... A relatively fast-moving (45-50 kt) bowing complex continues east-northeastward early this morning across south-central/southeast Louisiana toward the far southern Mississippi border vicinity. Strong rear-inflow/MCV characteristics are readily apparent in observational data including regional WSR-88D VWP winds. A 68kt/78 mph wind gust was recently measured at Baton Rouge, LA near/north of the apex of the bowing complex. This cluster of storms should continue to produce potentially severe wind gusts this morning, although its northern extent may increasingly be hostilely influenced by southward-sagging convective outflow/effective front that precedes it. Regardless, some severe-wind potential may persist into the afternoon, particularly in areas that are within roughly 50-80 miles of the Gulf coast. ...South-central Texas... As the cold front stalls and begins to gradually return northward later today, strong diurnal heating and deep surface moisture could support very isolated storm development across the higher terrain of the Edward Plateau and south-central Texas. Area RAP soundings show steep mid-level lapse rates (~8 C/km) and 2000-2500 J/kg of MLCAPE, which could support a conditional severe risk for hail and damaging gusts if storms were to develop. However, this currently appears unlikely given subtle mid-level height rises and limited ascent away from the slow-moving front. As such, probabilities will continue to be withheld given the relatively low/conditional nature of the risk. ..Guyer/Bentley.. 03/24/2025 Read more

Day 4-8 Outlook
Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0402 AM CDT Mon Mar 24 2025 Valid 271200Z - 011200Z ...DISCUSSION... Medium-range/global models have come into reasonable agreement with respect to the most recent run, signaling toward heightened severe risk over the upcoming weekend across central portions of the country. Days 4-5 (Thursday/Friday), locally strong storms will be possible across a rather broad portion of the central of the country, from the Upper Midwest to the southern Plains Day 4/Thursday, and the Plains into the Ohio Valley Friday. This will occur as a weak/slow-moving southern stream trough moves slowly east-northeastward across this region. Somewhat limit risk, over a broad geographic area, precludes introduction of any 15% risk areas either of these two days. Meanwhile, the primary synoptic pattern -- even early in the period -- favors a persistent lee surface low/trough over the High Plains. This will allow southerly low-level flow to evolve/expand across almost all of the central and eastern portions of the country as a warm front shifts northward into the northern CONUS. By early Saturday/Day 6, height falls associated with a strengthening trough moving across the Intermountain West should begin to spread into the Plains, with the trough itself currently expected to reach the High Plains. This will result in an eastward advance of a surface low front out of the High Plains and across the central Plains states through the evening/overnight. With a moistening pre-frontal boundary layer ahead of the advancing system, and increasing flow aloft, the overall setup will favor increasing severe potential, with all-hazards possible. Day 7/Sunday, eastward advance of the synoptic-scale features will continue, along with some continued strengthening. With continued moistening of the pre-frontal warm sector supporting afternoon destabilization, along with increasing deep-layer flow, a broad area of severe risk seems likely to evolve -- centered over the Mid and Lower Mississippi/Lower Ohio/Tennessee Valleys. Again -- all severe weather hazards would be possible. Monday, the primary focus for convective potential will shift east of the Appalachians. Here, weaker low-level moisture (and thus less robust destabilization potential) is expected at this time. Therefore, while severe risk may evolve, thermodynamic uncertainty precludes initiation of a risk area for Day 8/Monday. Read more

SPC 0730Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0230 AM CDT Mon Mar 24 2025 Valid 261200Z - 271200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE PACIFIC NORTHWEST... ...SUMMARY... A few strong/severe storms will be possible across portions of the Pacific Northwest on Wednesday. ...Synopsis... A slowly progressive upper pattern will persist across the U.S. Wednesday, as an eastern U.S. trough continues to advance slowly toward the Atlantic Coast. Upstream, ridging over the interior West will gradually expand into the Plains, while still farther upstream, a second upper trough over the eastern Pacific approaches the northwestern states. At the surface, the primary feature will be a cold front shifting into/across the Pacific Northwest, while the parent occluded low remains offshore through the period. ...Portions of the Northwest... As the eastern Pacific upper low nears the Pacific Northwest Coast, cold air aloft/steep mid-level lapse rates will overspread the area, atop low 50s surface dewpoints. This will combine with afternoon heating to support development of 500 to 1000 J/kg mixed-layer CAPE. Meanwhile, the approach of the upper system will also allow deep-layer south-southwesterly flow to increase across the area, allowing shear to become favorable for supporting organized updrafts -- potentially including a few rotating storms. As such, local risk for hail and/or damaging wind gusts may evolve during the afternoon and evening, spreading across parts of Washington and Oregon and possibly into western/northern Idaho by evening. While coverage of the stronger storms should remain rather sparse, the degree of risk appears to warrant introduction of 5%/MRGL risk across this area. ..Goss.. 03/24/2025 Read more

Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0204 AM CDT Mon Mar 24 2025 Valid 251200Z - 261200Z ...NO CRITICAL AREAS... ...Synopsis... Fire-weather conditions appear unlikely over much of the CONUS Tuesday. Amplified mid-level flow, with ridging in the west and broad troughing in the east, will persist with little change. A weak cold front will move south over the Plains keeping surface conditions dry. Surface high pressure should keep winds relatively light despite dry conditions over much of the central CONUS. While some localized fire-weather concerns are possible with gusty winds of 10-15 mph and low RH near the front in the southern Plains, more widespread fire-weather concerns are not expected. ..Lyons.. 03/24/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

A weak surface low over the central US will move southeast ahead of a second cold front moving across the northern and central Plains. Ahead of the front, veered low-level flow will gradually increase through the day across parts of OK and KS. Southwesterly gusts of 10-20 mph will occur with low afternoon RH around 25%. The dry and breezy conditions will overlap with very dry fuels supporting a few hours of elevated fire-weather conditions. Behind the secondary front across northern/central KS, gusty northwest winds are also possible for a few hours this afternoon. However, a cooler air mass will favor higher RH atop fuels that are less receptive. Some localized fire-weather concerns may develop, but more widespread concerns are not expected. ...Appalachians... In the wake of the first cold front, a few hours of gusty westerly winds are possible across the central and southern Appalachians.

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1257 AM CDT Mon Mar 24 2025 Valid 251200Z - 261200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Risk for severe weather appears low at this time across the U.S. on Tuesday. ...Discussion... A very slowly progressing upper pattern -- featuring an eastern U.S. trough and a ridge over the interior West -- will persist across the U.S. Tuesday. Through the second half of the period, an eastern Pacific trough is forecast to impinge on the West Coast. At the surface, the primary/remnant surface baroclinic zone -- which will have moved off the eastern seaboard prior to the start of the period, is forecast to trail westward from Florida to Texas. At this time, it appears that showers and a few thunderstorms will affect roughly the southern half of Florida during the afternoon, in the vicinity of the surface front, and near sea-breeze boundaries south of the front. Gusty winds and small hail may occur with one or two of the stronger storms. Farther west, a very conditional risk for isolated storm development appears to exist across central and northern Texas during the afternoon. Steep lapse rates/ample CAPE, but modest flow aloft suggests disorganized storms, but low/conditional risk for near-severe hail and/or wind is apparent. Overnight, elevated convection may develop north of the surface front, over the Oklahoma vicinity. However, modest CAPE suggests that any hail should remain sub-severe. Elsewhere, a few lightning flashes may be possible near Pacific Northwest coastal ranges very late in the period, as the upper trough approaches. Severe weather is not expected. ..Goss.. 03/24/2025 Read more

A few strong/possibly severe thunderstorms will be possible today from southern Louisiana eastward to southern Georgia and the Florida Panhandle. ...Synopsis... Amplified mid-level flow will progress across the CONUS as an upper trough moves from the Great Lakes into the Northeast, and a ridge builds steadily over the West. A cold front, trailing from a surface low will advance toward the Atlantic and Gulf Coast before stalling across south-central TX this afternoon. A band of thunderstorms will move southeastward across portions of the Southeast with a risk for marginal damaging gusts and hail. ...Southern LA, to southwest GA and the western FL Panhandle... A band of loosely organized thunderstorms are likely to be ongoing this morning ahead of the increasingly zonal cold front across parts of southern LA, southern GA and the FL Panhandle. Moderate buoyancy and modestly strong westerly flow aloft may support a continued marginal hail and wind risk as these storms approach the Gulf Coast. The most likely area for this appears to be across far southern LA and MS. At least a couple hours of filtered diurnal heating is possible ahead of the band of storms, along with access to somewhat steeper mid-level lapse rates (~7 C/km) from the west. This could support a slight rejuvenation of convection for a few hours, with a risk for hail and damaging gusts. However, storms should move offshore by early afternoon while the front and the remaining unstable air mass stall just inland. Farther east into the Carolinas, the late return of the deeper surface moisture coupled with increasingly poor mid-level lapse rates ahead of the eastward moving cold front suggests buoyancy will not be large (< 500 J/kg MUCAPE). A few storms may still redevelop along the primary surface front, with potential for isolated gusty outflow winds. However, overall severe potential appears quite low given increasingly limited buoyancy. ...South-central TX... As the cold front stalls and begins to gradually lift northward, strong diurnal heating and deep surface moisture could support very isolated storm development across the higher terrain of the Edwards Plateau and south-central TX. Area RAP soundings show steep mid-level lapse rates (~8 C/km) and 2000-2500 J/kg of MLCAPE, which could support a conditional severe risk for hail and damaging gusts. However, this appears unlikely given subtle mid-level height rises and little ascent away from the slow moving surface front. As such, probabilities will continue to be withheld given the low conditional risk. ..Lyons/Darrow.. 03/24/2025 Read more

Valid 240124Z - 240330Z The severe weather threat for Severe Thunderstorm Watch 62, 63 continues. SUMMARY...Large hail will likely remain a threat for a few more hours this evening from the San Antonio area northeastward into east-central Texas and northern Louisiana. DISCUSSION...Slow-moving cells continue to evolve from northwest of San Antonio toward Austin, with an overall increase in areal coverage. Given these trends, it appears likely the hail threat in general will continue to propagate south over the next couple hours, posing a damaging hail risk with up to 2.00" diameter possible. The combination of the front, various outflow boundaries, and the diurnally deepened moist boundary layer all suggest storms will persist despite a slow increase in CIN. To the northeast, other clusters of storms were gradually increasing in size entering into northern Limestone and Freestone counties with hail and gusty wind risk. Given the unstable air mass across the entire area ahead of the cold front, additional storms may develop this evening, with localized hail risk. ..Jewell.. 03/24/2025 ...Please see www.spc.noaa.gov for graphic product...
