SPC Day 2 Fire Weather Outlook
Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1233 AM CST Fri Dec 27 2024 Valid 281200Z - 291200Z ...NO CRITICAL AREAS... ...Synopsis... A mid-level trough will exit the Plains on D2/Saturday before moving across the southeastern US. High pressure will build in across the western US, with heights rising over the Rockies. Cooler northwesterly flow will filter across the high terrain and into the Plains, with increasing relative humidity. Some strong northwesterly breezes will overlap relative-humidity reductions to around 15 percent across portions of far western Texas. Latest fuels guidance indicates that fuels within this region will not support wildfire spread, precluding need to include areas at this time. ..Thornton.. 12/27/2024 ...Please see www.spc.noaa.gov/fire for graphic product...

SPC 1200Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 1149 PM CST Thu Dec 26 2024 Valid 271200Z - 281200Z ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE CENTRAL GULF COAST STATES.... ...SUMMARY... A few strong to locally severe thunderstorms could occur today across parts of the central Gulf Coast states. ...Central Gulf Coast States... A lead shortwave trough will de-amplify today, moving northeastward into the Ohio Valley. In its wake, a large-scale upper-level trough will move from the southern Plains into the lower Mississippi Valley. At the surface, a cold front will advance eastward across the lower Mississippi Valley, with a moist airmass located in the central Gulf Coast states. At daybreak, a broken line of thunderstorms will likely be ongoing near the front. This line is forecast to gradually diminish this morning, as the shortwave trough moves away from the region. Increasing instability this afternoon should result in convective redevelopment along and near an axis of moisture and instability from south-central Mississippi east-northeastward into Alabama. The models suggest that the instability in the central Gulf Coast states will be displaced to the southwest of the stronger deep-layer shear, and that large-scale ascent will be weak. This will likely keep any severe threat isolated and marginal this afternoon. The strongest cells may have potential to produce isolated severe gusts, and perhaps a brief tornado. ..Broyles/Thornton.. 12/27/2024 Read more
