SPC Day 3-8 Fire Weather Outlook

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.
