DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1137 AM CDT SAT MAR 29 2025
VALID 291700Z - 301200Z
...CRITICAL FIRE WEATHER AREA FOR MUCH OF CENTRAL AND EASTERN NEW
MEXICO INTO PARTS OF WESTERN TEXAS...
MORNING VISIBLE SATELLITE SHOWS MODEST CLOUD COVER OVERSPREADING
PORTIONS OF THE SOUTHERN HIGH PLAINS (MAINLY NEW MEXICO), WHICH MAY
INHIBIT ROBUST BOUNDARY-LAYER MIXING TO A DEGREE. NONETHELESS,
ADEQUATE MIXING SHOULD STILL TAKE PLACE, IN TANDEM WITH INCREASING
SURFACE WESTERLY ISALLOBARIC FLOW DUE TO THE DEVELOPING PLAINS
CYCLONE, TO PROMOTE WIDESPREAD ELEVATED TO POTENTIALLY CRITICAL FIRE
WEATHER CONDITIONS. ONLY SLIGHT ADJUSTMENTS HAVE BEEN MADE TO THE
CRITICAL HIGHLIGHTS IN THE SOUTHERN HIGH PLAINS TO REFLECT THE
LATEST GUIDANCE CONSENSUS. ALSO, SURFACE OBSERVATIONS DEPICT THE
COLD FRONT ALREADY IMPINGING ON THE KANSAS/OKLAHOMA BORDER,
PROMOTING RELATIVELY COOLER/MOIST CONDITIONS TO THE AREA. AS SUCH,
ELEVATED HIGHLIGHTS HAVE BEEN TRIMMED IN THIS AREA.
BOUNDARY-LAYER HEATING CONTINUES ACROSS PORTIONS OF THE MID
ATLANTIC, DESPITE THE PRESENCE OF CLOUD COVER, WITH SURFACE
OBSERVATIONS SHOWING RH (CURRENTLY 40-45 PERCENT) CONTINUING TO
DROP. THEREFORE, ELEVATED HIGHLIGHTS HAVE BEEN MAINTAINED.

/ISSUED 0130 AM CDT SAT MAR 29 2025/
..SYNOPSIS
WITHIN THE BASE OF A LARGE-SCALE TROUGH OVER THE WEST, A MIDLEVEL
WEST-SOUTHWESTERLY JET STREAK WILL CROSS THE SOUTHERN ROCKIES AND
ADJACENT HIGH PLAINS DURING THE DAY. AT THE SAME TIME, A LEE CYCLONE
WILL PERSIST OVER THE CENTRAL PLAINS, WHILE A RELATED DRYLINE
SHARPENS OVER THE SOUTHERN PLAINS.
..SOUTHERN/EASTERN NEW MEXICO INTO WESTERN TEXAS
WEST OF THE DRYLINE, STRENGTHENING DOWNSLOPE FLOW WILL CONTRIBUTE TO
DEEP BOUNDARY-LAYER MIXING, WITH RH FALLING INTO THE SINGLE DIGITS
TO LOWER/MIDDLE TEENS. A MODEST PRESSURE GRADIENT PERIPHERAL TO THE
LEE CYCLONE, AND DEEP MIXING INTO THE STRONG FLOW ALOFT, WILL FAVOR
20-25 MPH SUSTAINED WEST-SOUTHWESTERLY SURFACE WINDS (WITH HIGHER
GUSTS). THIS COMBINATION OF WARM, DRY, AND WINDY CONDITIONS WILL
YIELD CRITICAL FIRE-WEATHER CONDITIONS DURING THE AFTERNOON.
..MID-ATLANTIC
ALONG THE NORTHWESTERN PERIPHERY OF AN EXPANSIVE SURFACE HIGH OVER
THE WESTERN ATLANTIC, A MODEST PRESSURE GRADIENT AND BREEZY/GUSTY
WEST-SOUTHWESTERLY SURFACE WINDS WILL DEVELOP ACROSS THE
MID-ATLANTIC. HERE, TEMPERATURES WILL CLIMB INTO THE UPPER 70S/LOWER
80S F WHILE RH FALLS TO AROUND 30 PERCENT DURING THE AFTERNOON.
GIVEN DRY/RECEPTIVE FUELS AND THE EXPECTATION FOR MINIMAL
PRECIPITATION ACROSS THE AREA TONIGHT, ELEVATED FIRE-WEATHER
CONDITIONS ARE EXPECTED.
