Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0141 AM CST Sun Nov 30 2025 Valid 011200Z - 021200Z ...NO CRITICAL AREAS... ...Synopsis... On the backside of a positively tilted midlevel trough moving eastward across the Rockies, expansive surface high pressure will build over the Great Basin/Intermountain West. This will result in an enhanced offshore pressure gradient across southern CA, while a belt of moderate midlevel northerly flow overspreads the area. These factors will contribute to breezy/gusty east-northeasterly surface winds amid 20-30 percent RH -- with a focus over the typical wind-prone mountains and valleys of eastern Ventura and western Los Angeles Counties. Locally elevated fire-weather conditions are possible where any marginally receptive fuels are exposed to the dry/breezy conditions. ..Weinman.. 11/30/2025 ...Please see www.spc.noaa.gov/fire for graphic product...Read more

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1251 AM CST Sun Nov 30 2025 Valid 011200Z - 021200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Scattered thunderstorms will develop along the Gulf Coast tomorrow (Monday) into early Tuesday morning. Severe thunderstorms are not currently expected. ...Synopsis... A mid-level trough will intensify while traversing the central CONUS tomorrow (Monday), resulting in surface low development along the Gulf Coast late in the period. As this occurs, a broad warm-air advection regime will become established across the Southeast, resulting in mainly elevated buoyancy (e.g. a few hundred J/kg MUCAPE) ushering inland. A broad shield of rain with embedded thunderstorms should become established across the Sabine River Valley into MS by 00Z, progressing eastward toward the eastern Gulf Coast by 12Z Tuesday morning. Most guidance indicates the warm front and associated surface-based buoyancy remaining just offshore, along with the anticipated surface low. However, some guidance (e.g. the 00Z NAM) hints at some surface based buoyancy reaching the shoreline in the 00-12Z period. Should this occur, a sparse severe threat cannot be ruled out. However, given that the guidance consensus strays from this scenario, severe probabilities have not been introduced at this time. ..Squitieri.. 11/30/2025Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1145 PM CST Sat Nov 29 2025 Valid 301200Z - 011200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... A few thunderstorms are possible along the Gulf Coast and southern Florida. Severe thunderstorms are not expected. ...Synopsis... Severe storm potential is low over the CONUS today. A broad upper trough over the Midwest will shift eastward with shortwave ridging in its wake. A second shortwave trough will intensify over the southern Rockies as flow aloft becomes more zonal over the eastern half of the US. At the surface, low pressure over the Great Lakes will quickly lift northward into Canada as a strong cold front sweeps south toward the US Gulf/Atlantic Coasts. High pressure and an arctic air mass behind the front will keep much of the US hostile to thunderstorm development. The only exception will be where modest instability can develop near the southeastern FL Peninsula, eastern Atlantic waters and the immediate Gulf Coast ahead of the cold front. Isolated thunderstorms that develop will be aided by modest mid-level southwesterly flow atop the surface frontal zone. These storms should move quickly offshore before midday as the front continues surging south. Residual buoyancy inland will become increasingly removed with time as high pressure and resulting offshore flow intensifies. Given the very weak instability and short residence time of onshore convection, severe weather is not expected. ..Lyons/Weinman.. 11/30/2025Read more
