Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0241 PM CDT Tue Jul 15 2025

Valid 161200Z - 171200Z

Only minor adjustments were made to previous forecast highlights. A
broad dry thunderstorm threat will remain across portions of the
Great Basin, Utah and Western Slope. Thermodynamic profiles remain
supportive of high-based thunderstorms with dry sub cloud layer
evaporation minimizing appreciable rainfall while increasing
potential new lightning ignitions over critically dry fuels. Dry and
breezy conditions across eastern NV and west-central UT will promote
an elevated fire weather threat amid fuel ERC values around the 97th
percentile, supporting fire spread.

...Synopsis...
A departing mid-level trough will bring continued breezy conditions
and Elevated fire weather concerns across portions of southeastern
Nevada into western Utah on Wednesday. Afternoon relative humidity
reductions to 10-15 percent will overlap winds 10-15 mph in these
regions. Fuels remain critically dry with recent dry lightning and
potential for quick spread of new fires.

...Dry Thunderstorms...
A broad area of dry thunderstorm activity will be possible again
from northern AZ into western CO, UT, southern WY, and portions of
eastern NV. High based thunderstorms are expected to continue to
bring little to no rainfall amid critically dry fuels. This will
support potential for new lightning ignitions.
