0142 AM CDT Thu Apr 15 2021

Valid 151200Z - 161200Z

...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF EASTERN ARIZONA INTO
CENTRAL NEW MEXICO AND FAR WEST TEXAS...

...Synopsis...
A mid-level trough is expected to eject into the Plains states
during the day, with a belt of 60+ kt 500 mb flow expected to
overspread a deep, dry boundary layer across portions of the Lower
Colorado River Basin towards the southern High Plains. Rapid surface
low development is expected by afternoon, promoting very dry and
breezy conditions across portions of the Southwest, which will
support rapid wildfire spread.

...Eastern Arizona into New Mexico and Far West Texas...
The combination of boundary-layer mixing/downward momentum transport
of the stronger mid-level flow, and gradient wind given the
deepening surface low, are expected to contribute to widespread 25+
mph sustained westerly surface winds across eastern Arizona into New
Mexico and far west Texas. With widespread 10-20% RH in place
throughout the afternoon, and given dry fuels supporting wildfire
spread, Critical highlights have been maintained. At least Elevated
conditions are also expected farther west across northern portions
of Arizona.

Day 2 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0201 AM CDT Thu Apr 15 2021

Valid 161200Z - 171200Z

...Synopsis...
Broad cyclonic flow aloft is expected to persist across the southern
U.S., while a surface cold front surges southward across the Plains
states. Modestly dry and breezy conditions may accompany westerly
downslope flow ahead of the cold front across portions of far west
Texas into the Trans Pecos region, promoting modest wildfire-spread
potential.

...Portions of southwestern Texas...
By afternoon peak heating, 10-20% RH is expected in the vicinity of
the Davis and Chisos Mountains due to deep boundary-layer mixing.
Downslope westerly flow and the departure of a surface low to the
east will both encourage 15+ mph sustained westerly surface winds,
coinciding with the favorable RH during the afternoon and preceding
cold frontal arrival. Elevated fire weather highlights have been
introduced since fuels are quite dry and receptive to wildfire
spread.
