VALID 181700Z - 191200Z
...CRITICAL FIRE WEATHER AREA FOR PARTS OF SOUTHERN/EASTERN NEW
MEXICO INTO FAR WEST TEXAS...
..1630 UPDATE
A FASTER SOUTHWARD PROGRESSION OF A BACKDOOR COLD FRONT ACROSS THE
TEXAS PANHANDLE AS FAR SOUTH AS US-70 HAS TEMPORARILY MITIGATED FIRE
WEATHER CONCERNS ACROSS THE AREA. HOWEVER, SOME NORTHEASTWARD
RETREAT AND DAYTIME MIXING SHOULD ALLOW DRY SOUTHWEST FLOW TO RETURN
TO PORTIONS OF NORTHEASTERN NEW MEXICO AND THE TEXAS PANHANDLE
SUPPORTING AT LEAST A BRIEF PERIOD OF ELEVATED FIRE WEATHER
CONDITIONS TO EMERGE WITHIN THIS ZONE. THE CRITICAL FIRE WEATHER
THREAT WILL CONTINUE FOR MUCH OF SOUTHEASTERN NEW MEXICO.
EASTERN EXTENT OF ELEVATED HIGHLIGHTS WERE TRIMMED ALONG THE FLORIDA
ATLANTIC COAST AS HIGHER DEWPOINTS/RELATIVE HUMIDITY ACCOMPANY
SOUTHEASTERLY ONSHORE FLOW. FARTHER INLAND HOWEVER, ELEVATED FIRE
WEATHER CONDITIONS EXPECTED WITH EAST-SOUTHEAST WINDS OF 10-15 MPH
AND RELATIVE HUMIDITY DROPPING INTO THE 35-40 PERCENT RANGE THIS
AFTERNOON AMID INCREASINGLY DRY FUELS.

BE MORE COMMON. THE DRIEST FUELS WILL BE IN NEW MEXICO AND THE
TRANS-PECOS. FARTHER EAST IN THE TEXAS PANHANDLE/SOUTH PLAINS,
TRANSITIONAL/GREENING FUELS WILL MITIGATE FIRE WEATHER CONCERNS EVEN
