Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0156 AM CDT Fri Aug 01 2025

Valid 021200Z - 031200Z

...Synopsis...
A midlevel shortwave trough will deamplify as it moves slowly
eastward across the northern Great Basin during the day. Large-scale
forcing for ascent and steep low/midlevel lapse rates preceding this
feature will promote another day of isolated to widely scattered
high-based thunderstorms across the northern Great
Basin/Intermountain West. Around 0.5-0.7 inch PW and modest storm
motions will support mostly dry thunderstorms, posing a risk of
lightning-induced ignitions over receptive fuels.

Between the shortwave trough and a large-scale ridge over the
Southwest/northern Mexico, moderate midlevel westerly flow will
overspread a deeply mixed boundary layer over parts of the
Southwest/Great Basin into the central Rockies. Single-digit to
lower teens RH and breezy west-southwesterly surface winds will
yield elevated to locally critical fire-weather conditions across
parts of northern AZ, much of southern/central UT, and far western
CO during the afternoon.
