Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1251 AM CDT Tue Jun 24 2025

Valid 241200Z - 251200Z

...Synopsis...
Elevated fire weather conditions are expected again today across
parts of the Four Corners and Intermountain West. Early-morning
water-vapor imagery reveals an upper low migrating into the lower
Colorado River Valley. This feature is expected to meander across
the southern Great Basin through the day with a belt of modest
(20-40 knot) southwesterly mid-level flow extending from northern AZ
into southern WY. Under this speed max, dry conditions persist
across the region with afternoon RH minimums in the teens expected.
Although surface pressure gradient winds will likely only remain in
the mid teens, frequent gusts between 20-35 mph are expected as
ample diurnal heating drives deep boundary-layer mixing. Fuels
across the region remain supportive of fire spread given recent fire
activity and no appreciable rainfall over the past 1-2 weeks.

...Dry Thunderstorms - Northeast Nevada...
Cold temperatures aloft associated with the southern Great Basin
upper low, coupled with a modest influx of mid-level moisture and
deep boundary-layer mixing, will promote isolated weak thunderstorms
across portions of northeast NV. Thermodynamic profiles are typical
of dry thunderstorm environments; however, slow storm motions (less
than 10 knots) will promote wetting rainfall under the convective
cores. Isolated dry lightning strikes on the periphery of heavier
precipitation is possible, but confidence in a robust dry
thunderstorm threat remains limited.
