SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1143 PM CDT Tue Apr 08 2025 Valid 091200Z - 101200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE CENTRAL HIGH PLAINS... ...Synopsis... A mid-level trough will begin to amplify over the Ohio Valley as upper ridging builds in over the Interior West today. By afternoon, an 80+ kt 500 mb jet streak will overspread a dry boundary layer over the central/northern Plains. Downward momentum transport within this dry boundary layer will support 15-20 mph sustained northwesterly surface winds amid 20 percent RH. Given dry fuels across the central/northern Plains, Elevated highlights have been introduced where guidance consensus depicts the aforementioned dry/windy conditions persisting for several hours. Guidance consensus also depicts 20-25 mph sustained northwesterly surface winds coinciding with 10-15 percent RH across portions of the central High Plains, where Critical highlights are in place. Additionally, by afternoon, buoyancy (albeit scant) may support isolated, fast-moving/high-based thunderstorms over the same portions of the central Plains that will experience dry/windy surface conditions atop dry fuels. However, thunderstorms should be sparse at best over most areas, and it is unclear where a locally higher density of lightning flashes may occur, hence no isolated dry thunderstorms highlights introduced this outlook. ..Squitieri.. 04/09/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0755 PM CDT Tue Apr 08 2025 Valid 090100Z - 091200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Organized severe weather is not expected through Wednesday morning. Isolated strong storms remain possible over the next few hours in South Florida and the Keys as well as western South Dakota. ...Synopsis... A shortwave trough continues to approach the Florida Peninsula this evening. A weak surface boundary that is currently offshore may provide some focus for thunderstorms tonight. Another shortwave trough in Montana is responsible for isolated strong convection moving into western South Dakota. This activity may continue another couple of hours before weakening. ...South Dakota... The low-level airmass is quite dry; however, moisture is sufficient for isolated convection on the southern fringe of the shortwave trough. Small hail may occur with this activity, but the dry boundary layer is more likely to support strong to potentially marginally severe wind gusts. Activity should weaken over the next couple of hours and coverage will remain too isolated for adding severe probabilities. ...South Florida/Keys... The approach of the shortwave trough may promote a modest increase in convection along and near the surface boundary. Given diminishing surface temperatures and increase MLCIN, storms will become increasingly elevated with time. A strong gust could occur with the strongest storms, but this potential should remain spatially limited. ..Wendt.. 04/09/2025 Read more

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0457 PM CDT Tue Apr 08 2025 Valid 101200Z - 161200Z An amplifying mid-level trough will bring cooler temperatures and precipitation to much of the eastern U.S. through day 4/Friday. A strengthening high pressure ridge will promote potentially record setting heat across portions of the southwest desert and Intermountain regions beginning day 3/Thursday, lasting through the weekend (day 5 and 6). Model guidance consensus remains good in bringing an upper-level trough into the Pacific Northwest day 5/Saturday along with a subtropical jet component that should promote widespread Elevated to Critical fire weather conditions across the Desert Southwest on Saturday, spreading into the central and southern high Plains Sunday. Forecast uncertainty increases early next week but muted signals remain for at least some fire weather threat across portions of the southern Plains. ...Day 5/Saturday - Day 6/Sunday: Desert Southwest and High Plains... Critical fire weather conditions are possible across a large portions of the Desert Southwest on Day 5/Saturday in response to the encroaching upper-level trough into the Pacific Northwest and subtropical jet influence atop a very dry boundary layer and dry fuels. An area of 40 percent Critical probabilities was introduced for portions of southeast Arizona, where fuels will undergo several more days of drying, into much of New Mexico and southern Colorado for Saturday. Synoptically driven fire weather threat will continue for New Mexico but shift further into the central High Plains and front range of the Rockies as the trough translates eastward on day 6/Sunday. ..Moore/Williams.. 04/08/2025 ...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 0258 PM CDT Tue Apr 08 2025 Valid 091200Z - 101200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE CENTRAL HIGH PLAINS... Accelerating mid-level flow associated with an approaching 500 mb jet max will overspread the central Rockies, into the central High Plains tomorrow (Wednesday). This will promote stronger downslope west-northwest surface winds across portions of the central High Plains and adjacent front range areas. Although temperatures will be cooler owing to a post-frontal air mass, afternoon relative humidity is likely to fall to around 10 percent in a few locations. The dry air mass coupled with gusty winds and dry fuels is expected to generate Critical fire weather conditions across southeastern Wyoming extending southeastward into far northwestern Kansas. In addition, stronger northwest surface winds and relative humidity falling to the 20 to 30 percent range combined with sufficient available dry, fine fuels are expected tomorrow as well across a broad area from southeastern Montana into portions of South Dakota and far northwestern Iowa. Therefore, Elevated highlights were introduced to cover the heightened wildfire spread potential. ..Moore/Williams.. 04/08/2025 .PREV DISCUSSION... /ISSUED 1144 PM CDT Mon Apr 07 2025/ ...Synopsis... A mid-level trough will amplify over the central U.S., with an embedded 500 mb speed max poised to overspread the central Plains tomorrow (Wednesday). As surface high pressure builds over the northern Rockies, downslope flow across the central High Plains will promote another day of dry/windy conditions. 15-25 mph sustained westerly surface flow amid 20 percent RH will overspread dry fuels, warranting the introduction of Elevated highlights. Elsewhere across the central and southern High Plains, modestly dry and breezy conditions may develop and overspread fuels that have recently experienced appreciable precipitation accumulations, with no fire weather highlights introduced at this time. ...Please see www.spc.noaa.gov/fire for graphic product...
