Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0356 PM CDT Tue Jul 01 2025

Valid 031200Z - 091200Z

...Days 3-5/Thursday-Saturday...
An upper-level ridge will shift eastward from the Intermountain West
into the eastern U.S. through Day 5/Saturday while an upper-level
trough and cooler temperatures move into the Pacific Northwest,
mitigating fire weather concerns into the weekend. A mid-level
short-wave trough ejects into the Great Basin Days
3-4/Thursday-Friday bringing a period of stronger downslope flow
into western Nevada on Thursday, increasing the fire weather threat
amid drying fuels. A 50-60 knot mid-level jet associated with the
short-wave and an increasingly dry boundary layer will also support
stronger southwest winds across the southern Great Basin, increasing
wildfire spread potential. A mix of diurnally driven wet/dry
thunderstorms across the Intermountain West within a residual
monsoon moisture plume will decrease in coverage from west to east
as a dry southwest flow pattern is established across the Southwest.


...Days 6-8/Sunday-Tuesday...
Dry southwest flow aloft will keep monsoon moisture and associated
daytime convection primarily along the Continental Divide on Day
6/Sunday. A return of monsoon moisture into Lower Colorado River
Basin could return by Day 8/Tuesday in response to a nascent Four
Corners High, but forecast uncertainty in timing of moisture return
precludes introduction of critical probabilities at this time.
