SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0147 AM CST Wed Jan 15 2025 Valid 161200Z - 171200Z ...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. ..Squitieri.. 01/15/2025 ...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 0139 AM CST Wed Jan 15 2025 Valid 151200Z - 161200Z ...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHERN CALIFORNIA... ...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. ..Squitieri.. 01/15/2025 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1215 AM CST Wed Jan 15 2025 Valid 161200Z - 171200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected on Thursday. ...Synopsis... Upper shortwave ridging will spread east from the Plains into the Midwest on Thursday. This will occur as two shortwave upper troughs move across the Southwest and into the northern Plains/Upper Midwest by early Friday. At the surface, a deepening low will shift east across the Canadian Prairies, with an attending surface trough extending southward through much of the U.S. Plains states. Meanwhile, surface high pressure will remain over the Southeast, and Gulf moisture will remain suppressed will south of the U.S. Gulf coast. A cool, dry and stable airmass over much of the country will preclude thunderstorm potential. ..Leitman.. 01/15/2025 Read more

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1120 PM CST Tue Jan 14 2025 Valid 151200Z - 161200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorm probabilities are low across the CONUS today. ...Coastal Texas... Low-level warm advection is expected to remain focused along the TX Coast during the first half of the period. Notable surface boundary that is currently located over the northwestern Gulf Basin will be shunted southeast as mid-level flow becomes more northwesterly with the passage of a short-wave trough over the central Gulf States. Scattered elevated convection is currently noted along the cool side of the boundary, but lightning has struggled to materialize with this activity as updrafts are a bit too shallow/weak. Forecast soundings along the TX Coast suggest a few hundred J/kg MUCAPE if lifting a parcel around 750mb, but EL temperatures are marginal for lightning. A few of the more robust updrafts may penetrate levels that could support lightning, but thunderstorm activity is expected to remain a bit too sparse (less than 10 percent) to warrant an outlook this period. ..Darrow/Squitieri.. 01/15/2025 Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0630 PM CST Tue Jan 14 2025 Valid 150100Z - 151200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not expected tonight. ...01z Update... Weak mid-level disturbance is ejecting across northeast Mexico toward deep south TX early this evening. This feature should encourage weak elevated convection along the cool side of an offshore coastal boundary tonight. 00z sounding from BRO exhibits a modestly steep 3-6km lapse rate (7 C/km), and while moist, MUCAPE is only 100 J/kg. Lapse rates will likely remain a bit too weak, given the moisture, for updrafts to attain heights necessary for lightning discharge. ..Darrow.. 01/15/2025 Read more
