...CRITICAL FIRE WEATHER AREA FOR FAR NORTHWESTERN ARIZONA...CENTRAL
UTAH...AND FAR NORTHWESTERN COLORADO...

...Update...
Given the latest projected position of the mid-level shortwave
trough and hi-resolution model trends for tomorrow/Thursday, the
Isolated Dry Thunderstorm area was shifted eastward over more of the
Great Basin where a lack of widespread rainfall continues to result
in receptive fuels. For the Elevated area within the rest of the
Great Basin, northwestern AZ, UT, and a portion of the Rockies, an
upgrade to Critical was made through most of central UT where
sustained wind speeds near 20-25 mph are expected to persist for
several hours. The Elevated area was also extended eastward to
account for higher wind speeds and low teen to single-digit RH.

.PREV DISCUSSION... /ISSUED 0206 AM CDT Wed Jul 30 2025/

...Synopsis...
A mid-level trough, with embedded impulses, will linger along the
West Coast as upper ridging persists across the central and eastern
U.S. tomorrow (Thursday). Mid-level perturbations pivoting around
the West Coast upper trough will encourage widespread 15-20 mph
sustained southwesterly surface winds amid 15-20 percent RH across
much of the Great Basin. Since these conditions will overspread dry
fuels, Elevated highlights have been introduced.

As a mid-level impulse gradually drifts northward across the Pacific
Northwest, scattered thunderstorms will develop atop a dry boundary
layer and dry fuels. However, PWATs may be higher compared to
previous days, suggesting a potential mix of wet and dry
thunderstorms. While isolated dry thunderstorm highlights have been
introduced, consideration was also given for introducing Scattered
dry thunderstorm highlights. However, the possibility for several
storms producing wetting rains, and the potential for widespread
stability to overspread the Pacific Northwest due to high-density
thunderstorm coverage from Day 1, precludes greater highlights at
this time.
