Day 2 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0230 PM CDT Tue Aug 20 2024

Valid 211200Z - 221200Z

...20z update...
A few hours of elevated fire-weather conditions are possible over
parts of northern and central WY D2/Wed. Strong flow aloft will
overlap with deep mixing supporting gusty winds of 15-20 mph and RH
minimums of 10-15%. Fuels are at least partially receptive to spread
with pockets of ERC values above the 80th percentile. Thus, an
Elevated area was introduced over the best overlap of dry fuels and
elevated fire-weather potential.

Farther south across NV, the Great Basin, and eastern Snake River
Valley, a corridor of elevated to near-critical fire-weather
conditions remains apparent. Southwest surface winds of 20-25 mph
and RH below 15% will allow for elevated to near-critical
meteorological conditions to develop. However, this area currently
overlaps with fuels that are not overly receptive to wildfire
spread, with ERC values around the 60th-65th annual percentiles from
recent rainfall. With dry/windy conditions expected the preceding
day, some additional curing of fuels can be expected, and at least
some potential for elevated fire-weather concerns persists despite
uncertainties with fuel availability. See the prior discussion for
more information.

.PREV DISCUSSION... /ISSUED 0143 AM CDT Tue Aug 20 2024/

...Synopsis...
Broad southwesterly mid-level flow, and a progressive shortwave
trough moving through the northern Great Basin/Northwest U.S., will
bring sustained dry/windy conditions to portions of Nevada, Utah,
and Idaho on Wednesday. 

...Dry/Windy...
Deep boundary-layer mixing beneath broad southwesterly mid-level
flow, and a progressive shortwave trough moving from northern
Nevada/southern Oregon into Idaho and Montana, will be responsible
for elevated fire-weather conditions across the Great Basin on
Wednesday. High-resolution ensemble guidance suggests there may be a
narrow corridor of critical fire-weather conditions across Nevada,
where relative humidity values will drop into the single digits and
winds could get as high as 20-25 MPH. This area currently overlaps
with fuels that are not expected to be receptive to wildfire spread,
with ERC values around the 60th-65th annual percentiles. However,
with dry/windy conditions expected the preceding day, some
additional curing of fuels can be expected, and critical highlights
could be needed in subsequent updates. 

...Dry Thunderstorms...
A mix of wet and dry thunderstorms will be possible across
southwestern Montana, with additional dry thunderstorm development
likely across southern Colorado and northern New Mexico. However,
current fuels guidance suggests that both of these regions are
unlikely to be receptive to new ignitions and wildfire spread, with
ERC values below the 60th annual percentile for both regions.
