...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHERN/SOUTHEASTERN
UTAH INTO NORTHWEST COLORADO...

Another day of hot, dry, and breezy conditions is likely tomorrow
(Saturday) afternoon/evening across much of the southern/eastern
Great Basin and adjacent portions of northern Arizona, western
Colorado, and southwestern Wyoming. A Critical fire weather area was
introduced across portions of southern/eastern Utah and northwestern
Colorado, where several hours of sustained winds in excess of 20 mph
and minimum RH values around 10-15% overlapping critically receptive
fuels are expected.

Minor modifications were also made to the isolated dry thunderstorm
area over portions of the northern Great Basin and Intermountain
West based on the latest high-resolution ensemble guidance.

Please see the previous discussion below for more information on
tomorrow`s fire weather forecast.

.PREV DISCUSSION... /ISSUED 0156 AM CDT Fri Aug 01 2025/

...Synopsis...
A midlevel shortwave trough will deamplify as it moves slowly
eastward across the northern Great Basin during the day. Large-scale
forcing for ascent and steep low/midlevel lapse rates preceding this
feature will promote another day of isolated to widely scattered
high-based thunderstorms across the northern Great
Basin/Intermountain West. Around 0.5-0.7 inch PW and modest storm
motions will support mostly dry thunderstorms, posing a risk of
lightning-induced ignitions over receptive fuels.

Between the shortwave trough and a large-scale ridge over the
Southwest/northern Mexico, moderate midlevel westerly flow will
overspread a deeply mixed boundary layer over parts of the
Southwest/Great Basin into the central Rockies. Single-digit to
lower teens RH and breezy west-southwesterly surface winds will
yield elevated to locally critical fire-weather conditions across
parts of northern AZ, much of southern/central UT, and far western
CO during the afternoon.
