Day 2 Fire Weather Outlook

Valid 131200Z - 141200Z

...Update...
A few minor adjustments were made to the Elevated area for Thursday
based on latest fuel receptiveness and trends in overall high
resolution wind speed and RH model output. In general, the overall
forecast and previous reasoning below remains relatively unchanged.
The northern extent of the area was trimmed to exclude less
widespread receptive fuels across west-central UT, and extended
eastward over the Colorado Plateau of south-central UT where fuels
continue to become more receptive. In addition to the hot, dry, and
windy conditions expected over the aforementioned regions, a very
small Isolated Dry Thunder area was considered for the northwestern
Sierra Nevada Mountains of NV mainly east and southeast of Lake
Tahoe. However, given the uncertainty of fuels within the area of
question, dry thunder will not be included at this time.

.PREV DISCUSSION... /ISSUED 0153 AM CDT Wed Jun 12 2024/

...Synopsis...
A midlevel low will track slowly eastward across southern CA, while
a related belt of moderate/strong deep-layer southerly flow
overspreads the Desert Southwest into the southern Great Basin. This
will promote the development of a broad surface low over the Great
Basin, with a tightening surface pressure gradient along its
southern periphery. In response, around 20-25 mph sustained
southerly surface winds will develop across portions of northwestern
AZ, southwestern UT, and southern NV -- where a hot/deeply mixed
boundary layer and single-digit RH will be in place. Given
increasingly dry fuels across these areas, elevated fire-weather
conditions are expected.
