Day 2 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0142 AM CDT Thu May 24 2018

Valid 251200Z - 261200Z

...Synopsis...
Flow aloft across the Southwest will increase in response to an
approaching mid-level low centered over California.  As this occurs,
vertical mixing processes and a slight strengthening of the surface
pressure gradient across the Great Basin (compared to D1/Thu) will
result in enough flow for elevated fire weather conditions across
portions of the Southwest.  Elsewhere, quiescent larger-scale fire
weather conditions are expected.

...Northern Arizona, southern Nevada, and southern Utah...
The aforementioned synoptic pattern will result in broad areas of
15-20 mph southwesterly surface flow developing by peak heating
across the region.  Additionally, RH values will flirt with critical
thresholds across southern Nevada and northwestern Arizona while
falling into single digits across northeastern Arizona and vicinity.
While a few areas of critical atmospheric conditions are expected,
these thresholds are currently expected to be met on too brief of a
basis to necessitate any critical headlines at this time.  This
region will be re-evaluated in later outlooks.
