0200 AM CDT MON MAY 19 2025
VALID 191200Z - 201200Z
...CRITICAL FIRE WEATHER AREA FOR PARTS OF CENTRAL AND SOUTHERN NEW
MEXICO INTO FAR WEST TEXAS...
..SYNOPSIS
WITHIN THE BASE OF AN AMPLIFIED LARGE-SCALE TROUGH OVER THE WEST, A
70-80-KT MIDLEVEL SPEED MAXIMUM WILL OVERSPREAD PARTS OF THE
SOUTHWEST INTO THE SOUTHERN HIGH PLAINS. AS A RESULT, DRY/DOWNSLOPE
FLOW WILL OVERSPREAD MUCH OF CENTRAL/SOUTHERN NM INTO WEST TX --
WHERE CRITICAL FIRE-WEATHER CONDITIONS ARE EXPECTED. UPSTREAM OF THE
LARGE-SCALE TROUGH, ENHANCED NORTHWESTERLY FLOW WILL PERSIST ACROSS
CENTRAL CA, FAVORING ELEVATED FIRE-WEATHER CONDITIONS.
..CENTRAL/SOUTHERN NEW MEXICO INTO WEST TEXAS
THE DRY/DOWNSLOPE FLOW AND AMPLE DIURNAL HEATING WILL CONTRIBUTE TO
DEEP BOUNDARY-LAYER MIXING INTO THE BELT OF STRONG DEEP-LAYER
WESTERLY FLOW BENEATH THE MIDLEVEL SPEED MAXIMUM. AT THE SAME TIME,
THE PRESSURE GRADIENT WILL TIGHTEN ALONG THE PERIPHERIES OF A
DEEPENING SYNOPTIC-SCALE SURFACE LOW OVER THE SOUTHERN PLAINS. THESE
FACTORS WILL YIELD AN EXPANSIVE AREA OF 20-30 MPH SUSTAINED WESTERLY
SURFACE WINDS AND AROUND 15 PERCENT RH EXTENDING FROM
CENTRAL/SOUTHERN NM INTO WEST TX DURING THE AFTERNOON. GIVEN DRY/
RECEPTIVE FUELS, CRITICAL FIRE-WEATHER CONDITIONS ARE EXPECTED.
..CENTRAL CALIFORNIA
BOUNDARY-LAYER HEATING/MIXING AMID THE ENHANCED NORTHERLY FLOW ALOFT
WILL FAVOR DRY/BREEZY CONDITIONS ACROSS PARTS OF THE SOUTHERN
SACRAMENTO VALLEY INTO THE SAN JOAQUIN VALLEY DURING THE AFTERNOON
-- WHERE ELEVATED FIRE-WEATHER CONDITIONS ARE EXPECTED.
