Day 3-8 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

0412 PM CDT Sun Jun 28 2026



Valid 301200Z - 061200Z



A shortwave trough will traverse the Interior West on Day 3/Tuesday,

promoting southerly flow across the Southwest into the central

Rockies before shifting northward into the Upper Midwest on Day

4/Wednesday. Persistent troughing, enhanced flow aloft, and an

established dry airmass will maintain fire weather threats across

the Great Basin and Southwest. Meanwhile, a strong ridge of high

pressure will continue to build across the central-eastern CONUS

through the forecast period, promoting widespread above normal

temperatures with mostly dry conditions.



Enhanced southwesterly flow associated with persistent upper-level

troughing will sustain fire weather concerns across the Southwest,

Great Basin, and CO Rockies next week. As such, 40% probabilities

have been maintained on Day 3/Tuesday, and Days 5-6/Thursday-Friday

where dry and breezy winds are forecast to overlap receptive fuels.

Beyond Day 6/Friday, extended guidance hints at the potential for a

pattern change. The upper-level trough is forecast to lift into the

northern Plains, while ensembles depict ridging may build across

northern Mexico and into the Southwest sometime next weekend. This

could potentially allow monsoonal moisture to advect northward;

however, varying model trends lend to lower predictability in the

overall pattern evolution.
