Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
1124 AM CDT Wed Apr 13 2022

Valid 131700Z - 141200Z

...CRITICAL FIRE WEATHER AREA FOR SOUTHERN HIGH PLAINS...

The forecast remains mostly on track. The primary change was to
adjust the Elevated area in the central Plains. Some locations may
not observe humidity near critical thresholds given persistent
mid/upper clouds, particularly in southwest Kansas. Duration of fire
weather concerns in east-central/northeast Colorado may be short,
but conditions are still expected to be briefly Critical as stronger
downslope winds develop.

.PREV DISCUSSION... /ISSUED 0203 AM CDT Wed Apr 13 2022/

...Synopsis...
A strong upper low and active mid-level jet over the center of the
CONUS will continue to amplify today, keeping strong flow over the
Southwest and southern High Plains. At the surface, a cold front
moving through the Plains early this morning will scour surface
moisture resulting in very dry airmass. Strong westerly winds and
dry conditions will support active fire weather conditions within
dry fuels. 

...Southern High Plains into west Texas...
As the upper trough/low over the Plains/Midwest continues to lift
away, strong northwesterly flow aloft will fill in across the
Southwest and southern High Plains. Progression of the upper-level
system has generally been slower than previous guidance, suggesting
some misalignment between the strongest winds and diurnal heating.
While winds will be slightly weaker/delayed, frequent gusts to 35
mph along with strong subsidence and downsloping should still favor
extremely dry surface conditions. Model soundings showing mean
mixed-layer RH values as low as 2-3% coincident with the winds which
should support widespread Critical fire weather conditions within
extremely dry fuels. The highest confidence in winds of 30+ mph
appears to be across far eastern NM closer to the ejecting mid-level
jet. While confidence is lower, a few hours of localized Extremely
Critical conditions may occur within a corridor from eastern NM
through the southwestern TX Panhandle. 

...Central High Plains...
Dry and windy conditions should develop for a few hours across the
central High Plains and lee of the Rockies in the dry post-frontal
airmass as strong flow aloft lingers over the Rockies. While surface
temperatures should be cooling, low relative humidity and gusty
winds should support downsloping and drying with RH of 10-20%
likely. Elevated and Critical fire weather conditions are possible
for a few hours before the arrival of cooler temperatures and higher
humidity later in the evening and overnight.
