Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0212 AM CST Thu Dec 04 2025 Valid 061200Z - 071200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms are possible along the Gulf Coast on Saturday. Severe storms are not currently in the forecast. ...Synopsis... A mid-level trough will traverse the Plains and impinge on the Midwest on Saturday, prompting a surface low over the central High Plains to translate southeastward toward the Gulf while weakening. The approach of the weakening low will spur some low-level warm-air advection and return flow along the Gulf shoreline. Buoyancy driven by this moisture however, is forecast to be scant, so mainly isolated thunderstorms are forecast, with severe thunderstorms currently not a concern. ..Squitieri.. 12/04/2025Read more

Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1254 AM CST Thu Dec 04 2025 Valid 051200Z - 061200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms are not forecast tomorrow (Friday) or Friday night. ...Synopsis... Broad mid-level troughing will overspread much of the CONUS tomorrow (Friday), prompting a surface trough to impinge on the Great Lakes region while another surface low quickly develops along the northern High Plains. Regardless of the synoptic weather pattern in place, a relatively cool/dry, statically stable airmass will encompass much of the Interior West, to the Plains states, eastward to the Atlantic Seaboard. Therefore, thunderstorm development will be limited across much of the CONUS. The one exception will be along the Gulf Coast. Here, low-level moisture advection, prompted by an approaching upper trough, will supply enough deep-layer ascent amid scant buoyancy (e.g. a few hundred J/kg MUCAPE) for a few thunderstorms through Friday. ..Squitieri.. 12/04/2025Read more

Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1149 PM CST Wed Dec 03 2025 Valid 041200Z - 051200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Severe storms are not forecast in the U.S. today or tonight. ...DISCUSSION... Across the U.S. today, mid-level flow will remain northwesterly in the western states as a trough moves through the Great Plains. West-southwesterly flow aloft will be in place across the Southeast. At the surface, a moist airmass will be located over the western and central Gulf. Isolated to scattered thunderstorms will be possible along the northern edge of the moist airmass along parts of the western and central Gulf Coast, and further north into the lower Sabine and lower Mississippi River Valleys. Low-level moisture and instability is expected to be insufficient for severe storms. Elsewhere across the continental U.S., thunderstorms are not forecast today or tonight. ..Broyles/Weinman.. 12/04/2025Read more

Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0946 PM CST Wed Dec 03 2025 Valid 051200Z - 061200Z ...NO CRITICAL AREAS... ...Synopsis... Downslope flow off the southern Rockies and weak lee cyclogenesis over the central High Plains will favor 15-20 mph sustained westerly surface winds and 15-20 percent RH from east-central NM into the TX South Plains during the afternoon. However, ongoing precipitation atop marginal fuels should limit most fire-weather concerns. ..Weinman.. 12/04/2025 ...Please see www.spc.noaa.gov/fire for graphic product...Read more

Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0946 PM CST Wed Dec 03 2025 Valid 041200Z - 051200Z ...NO CRITICAL AREAS... ...Synopsis... Expansive surface high pressure characterized by cold surface temperatures will limit fire-weather concerns across the CONUS. Locally dry/breezy offshore flow will continue across parts of southern CA, though marginal fuels and weaker surface winds compared to previous days should mitigate the overall risk. ..Weinman.. 12/04/2025 ...Please see www.spc.noaa.gov/fire for graphic product...Read more
