Day 3-8 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0441 PM CDT Wed Jul 09 2025

Valid 111200Z - 171200Z

...Days 3-4/Friday-Saturday...
A building mid-level ridge across the Western U.S. will promote
lighter winds overall but steadily increasing temperatures across
the region through the weekend. Farther east, a mid-level trough
moving through the northern High Plains Days 3-4/Friday-Saturday
will usher in cooler, post-frontal flow into much Northern/Central
Plains through the weekend while also bringing scattered
showers/thunderstorms to the central and southern High Plains, with
wetting rains remaining along and east of the Continental Divide.

...Days 5-6/Sunday-Monday...
Another mid-level trough translating southeastward from British
Columbia into the Northern Tier states could bring a thunderstorm
threat to portions of the Northern Rockies and MT High Plains Day
5/Monday but a deeper moisture plume could limit dry thunderstorm
potential. Higher confidence exists for dry and breezy conditions
across the Columbia River Basin on Sunday as stronger mid-level flow
promotes dry, downslope winds into the basin, as well as accelerated
valley winds across the Snake River Plain amid dry fuels and low RH
on Monday.

...Day 7-8/Tuesday-Wednesday...
A West Coast thermal trough will promote well above normal
temperatures and low relative humidity across the coastal ranges of
northern CA, OR and WA but winds appear to remain light from latest
model guidance consensus. Additionally, confidence remains low of a
return of deeper monsoon moisture into the Southwest around midweek,
precluding introduction dry thunderstorm probabilities at this time.
