SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0208 AM CST Tue Jan 14 2025 Valid 151200Z - 161200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHERN CALIFORNIA... ...Synopsis... A belt of stronger mid-level east-northeasterly flow, along with surface high pressure over the Great Basin, will continue to support a pronounced pressure gradient across southern California, where dry offshore flow will remain a concern for most of the Day 2 (Wednesday) period. Latest guidance consensus shows at least 25 mph sustained winds amid 10-20 percent RH across terrain favoring areas from the Ventura Valley to the Laguna Mountains. These conditions are most likely during the first half of the period, with Critical highlights added to address the wildfire-spread potential. ..Squitieri.. 01/14/2025 ...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 0152 AM CST Tue Jan 14 2025 Valid 141200Z - 151200Z ...EXTREMELY CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE VENTURA VALLEY TO THE SAN BERNARDINO MOUNTAINS IN SOUTHERN CALIFORNIA... ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHERN CALIFORNIA... ...Synopsis... A belt of stronger northeasterly mid-level flow will overspread southern California as a 500 mb cut-off low attempts to drift southwest from the coastline today. A localized tightening of the surface pressure gradient is likely during the morning hours, encouraging very strong, dry offshore flow from the Ventura Valley to the Laguna Mountains. Widespread 20-30 mph sustained offshore winds are likely (perhaps with gusts exceeding 50 mph at times) for much of the period, warranting the maintenance of Critical highlights. Similar to yesterday, the best chance for sustained 30-40 mph winds amid 10 percent RH will be from around the Ventura Valley to the San Bernardino Mountains. Here, Extremely Critical highlights remain given the potential for very dangerous wildfire-spread conditions and the potential for extreme fire behavior. ..Squitieri.. 01/14/2025 ...Please see www.spc.noaa.gov/fire for graphic product...

Thunderstorms are not expected on Thursday. ...Synopsis... Upper ridging will overspread the central portion of the CONUS on Thursday. Meanwhile, an upper shortwave trough will begin to dig across the Pacific Northwest toward the end of the period while an upper low offshore the southern CA and Baja coast becomes an open wave and shifts east toward the lower CO River Valley. Strong surface high pressure over the Southeast will preclude northward transport of Gulf moisture as low-level trajectories remain oriented offshore. A dry and stable airmass will preclude thunderstorm potential. ..Leitman.. 01/14/2025 Read more

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1228 AM CST Tue Jan 14 2025 Valid 151200Z - 161200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Minimal to no lightning is expected across the U.S. on Wednesday. ...Synopsis... Strong surface high pressure from the Rockies into the southern Plains and Southeast will maintain a dry and stable airmass across most of the CONUS. This will preclude inland thunderstorm activity for the most part. However, a few lightning flashes are possible just offshore, or perhaps near the immediate coast of south Texas, in the vicinity of weak surface low near the Lower Texas Coast. Coverage is expected to remain less than 10 percent, negating the need for a 10 percent general thunderstorm delineation. ..Leitman.. 01/14/2025 Read more
