NWS STORM PREDICTION CENTER NORMAN OK
1153 AM CDT TUE APR 29 2025
VALID 291700Z - 301200Z
DRY RETURN FLOW ACROSS THE MID-ATLANTIC WILL CONTINUE THROUGH THIS
AFTERNOON AHEAD OF A COLD FRONT EXPECTED TO MOVE THROUGH THE REGION
TONIGHT INTO WEDNESDAY MORNING. LATEST SURFACE OBSERVATIONS AND
MODEL GUIDANCE SHOWS PRIMARY FIRE WEATHER CONCERN CONCENTRATED OVER
A CORRIDOR FROM NEW JERSEY INTO CONNECTICUT WHERE RELATIVE HUMIDITY
AS LOW AS 25 PERCENT COMBINED WITH WINDS UP TO 20 MPH WILL BRING
ELEVATED FIRE WEATHER CONDITIONS THROUGH THIS AFTERNOON. IN
ADDITION, ELEVATED TO LOCALLY CRITICAL FIRE WEATHER CONDITIONS ARE
STILL EXPECTED ACROSS SOUTHERN NEW MEXICO INTO FAR WESTERN TEXAS AND
INTO THE BIG BEND AREA. ONLY MINOR TRIMMING OF ELEVATED HIGHLIGHTS
WAS NEEDED EAST OF THE SACRAMENTO MOUNTAINS IN SOUTHEASTERN NEW
MEXICO AS A POST-FRONTAL AIR MASS MITIGATES FIRE WEATHER CONCERNS
TODAY FOR THIS AREA.

..SYNOPSIS
AHEAD OF A SLOW-MOVING LARGE-SCALE TROUGH OVER THE FOUR CORNERS,
MODERATE-STRONG DEEP-LAYER SOUTH-SOUTHWESTERLY FLOW WILL OVERSPREAD
A DEEPLY MIXED POST-DRYLINE AIR MASS OVER SOUTHERN NM INTO THE
TRANS-PECOS. A MODEST PRESSURE GRADIENT AND ENHANCED WINDS THROUGH
THE BOUNDARY LAYER WILL YIELD 15-20 MPH SUSTAINED WEST-SOUTHWESTERLY
SURFACE WINDS (WITH HIGHER GUSTS) AND 5-10 PERCENT RH DURING THE
AFTERNOON. GIVEN DRY FUELS, ELEVATED TO LOCALLY CRITICAL
FIRE-WEATHER CONDITIONS ARE EXPECTED.
FARTHER EAST, DRY/BREEZY RETURN FLOW WILL DEVELOP ACROSS PORTIONS OF
THE MID-ATLANTIC STATES. WITH MODESTLY RECEPTIVE FUELS ACROSS THE
AREA, 10-15 MPH SOUTHERLY SURFACE WINDS AND AROUND 30 PERCENT RH
WILL FAVOR ELEVATED FIRE-WEATHER CONDITIONS.
