Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0203 PM CDT Fri Sep 04 2026

Valid 051200Z - 061200Z

...NO CRITICAL AREAS...

Locally elevated fire weather conditions are possible on Day
2/Saturday across central-northern Wyoming. While less widespread as
compared to Day 1/Friday, sustained southwesterly 10-20 mph winds
and RH values of 15-20% may overlap areas of receptive fuels;
however, the limited duration and spatial extent of meteorological
conditions precludes Elevated highlights. In southern Nevada and
western Utah, southerly winds of 15-20 mph will coincide with RH
values of 15-20%. These meteorological conditions will overlap a
broadly less receptive fuelscape (60-80th percentile ERCs), also
limiting an introduction of Elevated highlights.

.PREV DISCUSSION... /ISSUED 1257 AM CDT Fri Sep 04 2026/

...Synopsis...
Similar to Friday, upper-level troughing will persist across the
Pacific Northwest, bringing cloud cover, cooler temperatures, and
chances for rain. Upper-level ridging will also remain centered over
the southern Great Plains, with modestly strong southwesterly flow
aloft continuing over much of the Great Basin, northern Rockies, and
northern High Plains. This troughing pattern and attendant
precipitation are expected to largely mitigate fire weather concerns
across the western U.S. for Day 2/Saturday. Elsewhere, upper
troughing remaining over the Northeast along with a surface frontal
system will continue to bring chances for rain to portions of the
Midwest and East Coast.

...Great Basin into Central Wyoming...
Dry, southwesterly surface flow will be maintained across the
eastern/southeastern portions of the Great Basin and into portions
of central Wyoming on Saturday. Locally elevated fire weather
conditions may manifest across locations where recent rainfall
was minimal and/or where pockets of dry fuels remain. Generally
marginal fuels across this region are expected to preclude a broader
fire weather risk at this time, however. While fuels are more
receptive across portions of central Wyoming, confidence in an
extended period (3+ hours) of overlap between 15+ mph surface winds
and RH below 20% is lower compared to areas farther southwest.
