Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1124 AM CDT Wed Jul 29 2026

Valid 291700Z - 301200Z

...NO CRITICAL AREAS...

Along the periphery of monsoonal moisture, mixed wet/dry
thunderstorms capable of strong/severe wind gusts are expected this
afternoon across south-central to southeastern Idaho (See the SPC
Day 1 Convective Outlook). Despite 0.7-1.0" PWATs, a dry sub-cloud
layer and fast storm motions may restrict higher accumulations of
rainfall (except in areas that receive multiple rounds of
thunderstorms). Fuels range from the 70-90th percentile, with the
lowest ERCs in southeastern Idaho where recent (48-hour) rain has
fallen, increasing to the 90th percentile farther north and west.
Lightning ignitions cannot be ruled out, especially where drier
fuels exist. See the previous forecast discussion for additional
information.

...Synopsis...
Weak upper-level troughing will linger over the northwestern US with
a cold front stalling and weakening over the northwest Great Basin
into the northern Rockies. Upper-level heights will build over much
of the West while the upper high remains over the southern High
Plains/Rockies. Weak shortwave troughs may rotate through the weak
troughing over the northwestern US and around the western/northern
periphery of the upper high over portions of the Great Basin and
central Rockies.

Locally elevated conditions are likely to develop across portions of
Nevada with forecast southerly to westerly sustained winds of 10-15
mph with gusts of 20-25 mph amid minimum RH of 5-15%. The increase
of breezy winds will be along a surface thermal trough and below
slightly increased winds aloft due to a passing weak mid-level
shortwave trough. Active large fires near the periphery of monsoonal
moisture and thunderstorm chances in the central/eastern Great Basin
may produce deep pyroconvection as well.
