Day 1 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

1200 PM CDT Wed Mar 12 2025



Valid 121700Z - 131200Z



...EXTREMELY CRITICAL FIRE WEATHER AREA FOR MUCH OF THE EDWARDS

PLATEAU IN SOUTHWESTERN TEXAS...

...CRITICAL FIRE WEATHER AREA FOR FAR SOUTHEAST NEW MEXICO INTO MUCH

OF WESTERN AND CENTRAL TEXAS...



The forecast remains on track, and no changes were needed with this

update. The latest surface observations show high-end critical to

extremely critical meteorological conditions developing across the

Trans-Pecos (west of the Extremely Critical highlights). However,

less fuel loading in this region limits confidence in the overall

fire-weather risk compared to areas farther east -- precluding an

upgrade here. For additional details, see the previous discussion

below.



Elsewhere, dry/breezy conditions may favor locally elevated

fire-weather conditions across portions of the Ohio Valley,

Appalachians, and Mid-Atlantic, though a lack of stronger sustained

surface winds precludes the addition of highlights.

.PREV DISCUSSION... /ISSUED 0159 AM CDT Wed Mar 12 2025/



...Synopsis...

A mid-level trough will eject from the southern Rockies today,

supporting surface low development across the Southern Plains. A

dryline, pendant from the surface low, will surge eastward toward

the I-35 corridor in Texas during the afternoon, with very dry and

windy conditions behind the dryline supporting very dangerous

wildfire-spread potential. By afternoon peak heating, sustained

surface winds will exceed 20 mph amid RH dipping to at least 15

percent across much of the southern High Plains, warranting the

continuation of broad Elevated/Critical highlights. However, much of

western into central Texas may experience RH lowering to 10 percent

as sustained westerly surface winds reach 30 mph over several

locales, for at least a few hours. Extremely Critical highlights

have been introduced for the Edwards Plateau in southwestern Texas,

where these dangerous meteorological surface conditions will

overspread dry fuels that are highly receptive to wildfire spread.
