SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1150 PM CST Sun Nov 24 2024 Valid 261200Z - 271200Z ...NO CRITICAL AREAS... ...Synopsis... Strong, broad, zonal mid-level flow will overspread the CONUS as a mid-level trough traverses the Interior West tomorrow (Tuesday). Surface high pressure will build over the East and West Coasts while a surface low develops over the southern Plains. Modest return flow with the surface low will promote breezy conditions over the central and southern Plains. However, the lack of lower RH and receptive fuels precludes fire weather highlights. Elsewhere across the CONUS, the lack of either a stronger surface wind field, low enough RH, or dry enough fuels, suggest that widespread significant wildfire-spread concerns should remain limited. ..Squitieri.. 11/25/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC Day 1 Fire Weather Outlook
Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1149 PM CST Sun Nov 24 2024 Valid 251200Z - 261200Z ...NO CRITICAL AREAS... ...Synopsis... A mid-level trough will impinge on the East Coast while a second upper trough overspreads the Pacific Northwest and Great Basin areas today. Surface high pressure will build over the Plains states into Mississippi, Ohio, and Tennessee Valley areas behind a surface cold front. The net result will be cool and/or moist conditions behind the surface cold front over the central U.S., with precipitation accumulations occurring along the West and East Coasts. Overall quiescent fire weather conditions are expected, with no fire weather highlights introduced this outlook. ..Squitieri.. 11/25/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1147 PM CST Sun Nov 24 2024 Valid 261200Z - 271200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm potential appears low on Tuesday. ...Synopsis... Thunderstorm chances will be minimal across the CONUS on Tuesday, as a negative-tilt shortwave trough moves into Quebec, and a cold front progresses across the remainder of the Southeast. Showers may linger along the front from the southern Appalachians to the Mid Atlantic Tuesday morning, and a lighting flash or two cannot be ruled out over the southern AL to GA portion of the front. However, any convection should be short lived. Behind this initial system, the flow regime will become zonal into Wed morning, though a new trough may start to amplify across the Four Corners states. At that time, instability sufficient for thunderstorms appears unlikely. ..Jewell.. 11/25/2024 Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1136 PM CST Sun Nov 24 2024 Valid 251200Z - 261200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible from this afternoon into tonight from Louisiana into parts of the southern Appalachians and Mid-Atlantic. Additional storms may develop near the northern California and Oregon coasts. No severe threat is expected. ...DISCUSSION... A mid-level trough will move eastward across the central U.S. today, as an associated cold front advances southeastward into the Ark-La-Tex and Mid Mississippi Valleys. By evening, the front should be located from Louisiana northeastward into parts of the southern Appalachians. Convection is expected to develop along and near the front this evening as the mid-level trough approaches. Instability will remain very weak limiting the potential for severe storms. Elsewhere, a few lightning strikes could occur along the coasts of northern California and Oregon. No severe threat is expected. ..Broyles/Squitieri.. 11/25/2024 Read more

Isolated thunderstorms will be possible near the northern California and southern Oregon coasts tonight, but no severe threat is expected. ...DISCUSSION... A mid-level low, off the Pacific Northwest coast, will move slowly southward across the eastern Pacific. Strong west to southwesterly mid-level flow will be in place across much of California and Oregon. Isolated thunderstorms will be possible due to strong large-scale ascent, near the northern coast of California and southern coast of Oregon.

SPC Day 3-8 Fire Weather Outlook
Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0352 PM CST Sun Nov 24 2024 Valid 261200Z - 021200Z Fire-weather concerns over the CONUS are low through the extended forecast period. Predominately zonal mid-level flow will gradually amplify as broad troughing develops over the eastern US early in the week. Ridging and strong northwesterly flow will intensify over the western US as the upper-level pattern becomes quasi stationary. At the surface, a cold front and high pressure will shift over the central and eastern US as the ridge builds. A much cooler and stable air mass, reinforced by multiple intrusions of Arctic air, will favor weaker winds and poor overlap of dry conditions with receptive across much of the US into week 2. The only exceptions may be across parts of the southern High Plains and the FL Peninsula middle to late next week. Gusty winds behind a strong cold front could support periodic dry and breezy conditions from eastern NM and across central FL. However, fuels in both locations are not overly receptive, and model guidance varies substantially on the duration/intensity of any strong winds and low humidity that may develop. Thus, the probability of sustained critical fire-weather conditions is low. ..Lyons.. 11/24/2024 ...Please see www.spc.noaa.gov/fire for graphic product... Read more
