Day 1 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0200 AM CDT Thu Apr 21 2022

Valid 211200Z - 221200Z

...CRITICAL FIRE WEATHER AREA FOR EASTERN NEW MEXICO INTO THE
OKLAHOMA AND TEXAS PANHANDLES...

...Synopsis...
A large-scale trough will move ashore over the West Coast, while
broad west-southwesterly flow overspreads the Rockies. This will
encourage the development of a dryline over the eastern TX Panhandle
southward into northwest TX. Farther north, stronger downslope flow
will result in a deepening surface low over parts of WY, with a
corresponding tight pressure gradient developing over the central
High Plains. 

...Southwest into the southern High Plains...
Widespread 10-15 percent minimum RH will develop across the
Southwest into the southern High Plains, where breezy southwesterly
surface winds are expected. From eastern NM into the OK/TX
Panhandles, deep boundary-layer mixing into the enhanced flow aloft
will favor 5-10 percent RH amid 20-25 mph sustained southwesterly
surface winds behind the dryline. The co*bination of strong surface
winds and warm/dry boundary-layer conditions atop highly receptive
fuels will support a critical fire-weather threat.  

...Central High Plains...
In response to the tightening surface pressure gradient, strong
southerly surface winds of 25+ mph will overspread parts of the
central High Plains (including portions of northeastern CO, western
NE, and southeastern WY). While RH should generally remain above 30
percent owing to increasing moisture return, the strong/gusty
surface winds coupled with critically dry fuels could support at
least locally elevated fire-weather conditions during the afternoon.
 
...Florida Peninsula...
Breezy easterly surface winds near 15 mph will persist over the
Florida Peninsula. While minimum RH could fall to near 35 percent
over the western portion of the peninsula, a minimal overlap of the
breezy surface winds and low RH precludes highlights at this time.
