...CRITICAL FIRE WEATHER AREA FOR PARTS OF NORTHEAST NEW MEXICO INTO
THE NORTHWEST TEXAS PANHANDLE...
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF DEEP SOUTH TEXAS...

...Synopsis...
An upper trough and associated surface low will progress towards the
southern Mississippi Valley, with deep-layer dry northwesterly flow
prevailing across the Southern Plains today. Strong northwesterly
surface winds will support favorable conditions for grass-fire
spread to areas that have not experienced heavy rainfall
accumulations yesterday. Specifically, fire weather highlights have
been removed across portions of the Texas Rolling Plains/Big Country
given the passage of a mature squall line over fuels that were
modestly receptive at best. However, areas farther west (i.e. far
eastern New Mexico) and southward into Deep South Texas have
remained relatively devoid of precipitation accumulations.

Widespread 15-25 mph sustained northwesterly surface winds amid RH
under 20% are expected by afternoon peak heating across far eastern
New Mexico into Deep South Texas, where Elevated highlights have
been maintained. A focused corridor of potentially overlapping 20+
mph sustained northwesterly surface winds and 15% RH is likely along
the New Mexico/Texas Panhandle border area, prompting the
continuation of Critical highlights. Similarly, the Critical area
remains in place across Deep South Texas, where 20+ mph sustained
northwesterly surface winds and 15% RH are still expected.

Day 2 Fire Weather Outlook  
NWS Storm Prediction Center Norman OK
0152 AM CDT Wed Oct 27 2021

Valid 281200Z - 291200Z

...Synopsis...
A deep northwesterly flow regime will persist across the Southern
Plains as an upper trough and surface low slowly progress towards
the Ohio Valley tomorrow/Thursday. Similar to Day 1, Critically dry
and windy conditions will ensue across portions of the Southern
Plains. However, given the passage of heavy rainfall/thunderstorms
previous to Day 1, fuel receptiveness is expected to remain poor
across several locales. 

Portions of far western Kansas into the central Texas Panhandle have
not experienced overly heavy rain. Finer fuels are expected to be
receptive enough to support some grass-fire spread, and given 15-25
mph sustained northwesterly winds coinciding with 20% RH, Elevated
highlights have been introduced. Similar to Day 1, 15 mph sustained
northwesterly winds and 20% RH will persist across Deep South Texas,
prompting the introduction of Elevated highlights here as well.
