Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1158 AM CDT Fri Aug 23 2024

Valid 231700Z - 241200Z

...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE GREAT BASIN...

The Isolated Dry Thunderstorm highlights were expanded into
southwest Montana, where forecast soundings suggest the potential
for fast-moving, high-based thunderstorms over modestly receptive
fuels this afternoon. Some of these storms will be capable of
producing severe wind gusts (around 60 mph), aided by enhanced
deep-layer flow/shear and deep inverted-V thermodynamic profiles.
For details on the severe-thunderstorm risk, see the SPC Day 1
Convective Outlook. Additionally, the Critical area in the Great
Basin was expanded slightly eastward and southward, where the latest
high-resolution guidance has increased confidence in the overlap of
20-30 mph sustained southerly surface winds and single-digit to
lower-teens RH.

Over portions of the southern Plains, very hot and dry conditions
will develop this afternoon, which co*bined with breezy/gusty
southerly surface winds, may promote locally elevated fire-weather
conditions. There will also be some potential for an isolated
lightning-induced ignition with thunderstorms over north-central TX.
Overall, the fire-weather risk across this region appears too
localized for highlights.

...Synopsis...
A mid-level trough will enter portions of the Pacific Northwest,
with enhanced mid-level flow overspreading portions of the Great
Basin and vicinity. Afternoon heating/mixing will result in
sustained surface winds of 20-25 mph while RH values drop into the
teens, resulting in Elevated to Critical fire-weather conditions for
this region. In addition, forcing for ascent associated with the
aforementioned trough will allow for thunderstorms to develop across
the Pacific Northwest, with a mix of wet and dry storms expected.
Given dry/receptive fuels across the region, the area delineating
isolated dry thunderstorm potential has been maintained.
