...CRITICAL FIRE WEATHER AREA FOR SOUTHERN NEW MEXICO INTO THE FAR

WESTERN TRANS-PECOS...



...Synopsis...

Downstream of an amplified large-scale trough over the West, a belt

of strong deep-layer southwesterly flow will overspread the southern

Rockies and adjacent High Plains. In the low-levels, a related lee

trough will deepen over the southern High Plains. 



...Southern New Mexico into the far western Trans-Pecos...

West of the lee trough, downslope flow amid a dry antecedent air

mass will promote deep boundary-layer mixing into the belt of

enhanced southwesterly flow aloft. At the same time, the pressure

gradient will tighten along the periphery of the deepening lee

trough during the afternoon. This will result in a corridor of 10-15

percent RH across much of the southern Rockies and adjacent High

Plains. These dry boundary-layer conditions, coupled with 20 mph

sustained southwesterly surface winds (with higher gusts), will

promote critical fire-weather conditions atop dry fuels over

southern New Mexico into the far western Trans-Pecos -- with

elevated conditions expected northward into southeast Colorado.

Day 2 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

0200 AM CDT Mon Apr 28 2025



Valid 291200Z - 301200Z



...Synopsis...

Ahead of a midlevel trough moving eastward across the Southwest,

moderate southwesterly flow aloft will overspread the southern

Rockies and adjacent High Plains. Here, boundary-layer mixing along

the western periphery of a deepening lee cyclone over the TX

Trans-Pecos will favor dry/breezy conditions across southern NM.

Sustained surface winds of 15-20 mph amid 10 percent RH will yield

elevated to locally critical fire-weather conditions. 



Additionally, isolated high-based thunderstorms cannot be entirely

ruled out across portions of northern/central NM -- ahead of the

approaching midlevel trough. While this may promote a localized risk

of dry thunderstorms, confidence in sufficient coverage of storms

over dry fuels is too low to add Dry Thunderstorm highlights at this

time.
