SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0111 PM CST Wed Jan 15 2025 Valid 161200Z - 171200Z ...19z Update... Offshore winds should gradually weaken D2/Thursday morning as onshore flow returns by the afternoon/evening. Lingering strong gusts are possible in the terrain favored areas of the western LA Basin. However, with weakening winds and rising humidity, fire concerns are expected to be much lower than the last several days. See the prior outlook for info. ..Lyons.. 01/15/2025 .PREV DISCUSSION... /ISSUED 0147 AM CST Wed Jan 15 2025/ ...Synopsis... The surface high pressure gradient should begin to relax, with offshore flow gradually diminishing as the mid-level cutoff low morphs into an open wave and overspreads the Baja Peninsula tomorrow (Thursday). Before the pressure gradient weakens though, at least a few more hours of dry and breezy offshore flow will persist in terrain-favoring areas surrounding the Los Angeles metropolitan area, with Elevated highlights introduced. ...Please see www.spc.noaa.gov/fire for graphic product...

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1122 AM CST Wed Jan 15 2025 Valid 161200Z - 171200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected on Thursday. ...Discussion... An upper trough over the eastern U.S. will advance slowly eastward Thursday, while the next feature -- a short-wave trough over western Canada -- digs southeastward, moving into the northwestern/north-central U.S. overnight. At the surface, cold/dry/stable conditions will persist. A pronounced cold front, associated with the digging/western upper system, will likewise shift southeastward out of Canada, but preceding high pressure will preclude thunder potential ahead of the front -- and elsewhere across the CONUS. ..Goss.. 01/15/2025 Read more

Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1049 AM CST Wed Jan 15 2025 Valid 151700Z - 161200Z ...CRITICAL FIRE WEATHER AREA FOR PARTS OF SOUTHERN CA... ...17z Update... No changes were made to the valid outlook. Offshore winds are expected to increase this afternoon with gusts of 25-40 mph possible. The strong winds and minimum humidity near 10% will support critical fire-weather conditions over western portions of the LA Basin and in the higher terrain of southern CA. Fire concerns should slowly diminish this evening. See the prior outlook for more info. ..Lyons.. 01/15/2025 .PREV DISCUSSION... /ISSUED 0139 AM CST Wed Jan 15 2025/ ...Synopsis... Mid-level easterly flow will overspread southern California with the approach of a 500 mb cutoff low today, providing enough upper support, in tandem with a persisting surface pressure gradient, to promote continued dry offshore flow. By afternoon, sustained winds may exceed 20 mph (with higher gusts) over several locales, from the Ventura Valley to the Laguna Mountains. RH may dip to 10-20 percent with the stronger wind speeds, necessitating continued Critical highlights. ...Please see www.spc.noaa.gov/fire for graphic product... Read more
