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

The only change with this update was a slight southward expansion of
the Critical area into far northwest AZ and southern NV based on the
latest surface observations and high-resolution guidance consensus.
In addition to the fire-weather concerns described below, RAP
forecast soundings show deep inverted-V profiles over parts of
central into northeast UT -- supportive of isolated high-based dry
thunderstorms and the potential for a lightning-induced ignition or
two given receptive fuels. However, the anticipated limited coverage
of this activity precludes the introduction of dry thunderstorm
highlights.

.PREV DISCUSSION... /ISSUED 0143 AM CDT Sun Jul 03 2022/

...Synopsis...
An upper ridge will shift eastward into the Plains states as a
mid-level trough advances toward the Intermountain West today.
Surface lee troughing will materialize across the Great Basin, with
Elevated to Critical dry and windy conditions developing along the
Nevada/Utah during the afternoon hours. Scattered thunderstorms will
also develop across the northern Rockies into the Pacific Northwest
by afternoon peak heating. While some of these storms may be
high-based and potentially dry, overall wetter storms will beco*e
more abundant and traverse fuel beds that are marginally receptive
to fire spread, precluding dry thunderstorm highlights.
