Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0353 PM CST Tue Jan 20 2026 Valid 221200Z - 281200Z Fire weather concerns are likely to remain minimal through early next week across most of the contiguous U.S. An arctic air mass will begin filtering into the northern U.S. on Day 3/Thursday, reaching the Gulf and Atlantic Coast by Day 4/Friday, while an upper-level trough facilitates bringing increasing East Pacific and Gulf moisture into the Southwest and Southern Plains. A broad swath of mixed precipitation, including significant snow accumulations, will encompass much of the southern U.S. Day 4/Friday through Day 8/Tuesday mitigating fire weather concerns, particularly across the southern High Plains where fuels remain dry. The FL Peninsula and portions of the central Plains are likely to receive minimal precipitation, aiding in keeping fuels on the drier side through the weekend. ..Williams.. 01/20/2026 ...Please see www.spc.noaa.gov/fire for graphic product...Read more
