Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0158 AM CDT Tue Jul 19 2022

Valid 191200Z - 201200Z

...Synopsis...
A prominent ridge over the southwestern US is forecast to remain
quasistationary as a co*pact upper low traverses its northern flank.
Strong mid-level flow associated with the low will move east, but
linger over the central Rockies and western Great Basin through the
first part of the day. At the surface, a weak cold front will move
slowly south, supporting a few thunderstorms over the southern High
Plains. Extreme heat is forecast beneath the ridge across the
Southern Plains, aiding in the development of locally elevated fire
weather concerns. 

...Central High Plains...
In the wake of a dry frontal passage early this morning, downslope
northwesterly winds are forecast over much of eastern WY and western
NE. Dry west/northwest winds of 15-20 mph will be possible through
the first half of the day along with surface RH below 25%. With
plentiful critical fuels in place, elevated to locally critical fire
weather conditions will be possible through the afternoon and early
evening. Winds should weaken later in the afternoon through sunset
ending the fire weather threat this evening. 

...Southern High Plains...
Extreme heat is forecast beneath the stagnant mid-level anticyclone
centered over the southwestern US. While surface winds will likely
be light owing to the high pressure, surface temperatures in excess
of 110F are forecast through the afternoon. The very warm airmass
will favor significant mixing and low afternoon relative humidity
values below 20%. With fuels near record dryness, the very hot, dry
and unstable conditions will likely support locally elevated fire
weather concerns across much of TX, OK and western KS. Isolated
high-based thunderstorms may also be possible across the TX
Panhandle late this evening. While dry thunder chances appear modest
given high PWATs, a few lightning strikes within dry fuels appear
possible.
