Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0238 AM CST Sun Dec 28 2025 Valid 311200Z - 051200Z ...DISCUSSION... Return flow will ensue along the western Gulf Coast mid-week, yielding air mass modification from the prior continental intrusion. Bulk of deterministic guidance has trended toward earlier EC-AIFS signals of a low-amplitude shortwave trough progressing east across the southern states through late week. While run-to-run predictability and spread across models remains subpar, convective potential should increase by D6-7/Friday-Saturday across parts of the Gulf Coast States. At this point, with only modest cyclogenesis consistently progged, overall severe potential still appears marginal. Latest ML guidance from SPC-CSU and NSSL for the GEFS, and yesterday's NCAR for the ECENS, support this notion with individual day probabilities holding at 5 percent or less.Read more

Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0142 AM CST Sun Dec 28 2025 Valid 291200Z - 301200Z ...Synopsis... A mid-level trough will impinge on the East Coast tomorrow (Monday), resulting in northwesterly upper flow overspreading the Plains states through the Day 2 period. Northwesterly flow will also prevail at the surface over the Plains as surface high pressure settles over the region. Sustained surface north-northwesterly winds should peak around 15 mph by afternoon, amid 40 F surface temperatures and 15-25 percent RH. Given drying fuels, the aforementioned meteorological conditions should support low-end Elevated conditions. The best chance for these conditions will be across the eastern Texas Panhandle into northwest Texas and western Oklahoma, where Elevated highlights have been introduced. ..Squitieri.. 12/28/2025 ...Please see www.spc.noaa.gov/fire for graphic product...Read more

Day 1 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1254 AM CST Sun Dec 28 2025 Valid 281200Z - 291200Z ...Synopsis... A pronounced mid-level trough will traverse the central U.S. today, supporting the eastward advancement of a surface low and associated cold front sweeping across the MS Valley during the day. Strong northwesterly surface flow will overspread the Plains states, resulting in cooler temperatures but dry and windy conditions. Across portions of the southern Plains, behind the cold front, 25+ mph sustained northwesterly surface winds will prevail for several hours atop dry fuels. Despite 25-35 percent RH, the aforementioned combination of modestly dry fuels, and strong sustained winds, will yield high-end Elevated conditions for western and northern Texas into Oklahoma during the 18Z-00Z (Noon to 6 PM CST) time frame. ..Squitieri.. 12/28/2025 ...Please see www.spc.noaa.gov/fire for graphic product...Read more
