DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0148 AM CDT SUN APR 05 2026
VALID 051200Z - 061200Z
..SYNOPSIS
UPPER-LEVEL RIDGING WILL REMAIN IN PLACE ACROSS THE WEST TODAY WITH
LONGWAVE TROUGHING ACROSS THE GREAT LAKES REGION. CONCURRENTLY,
SURFACE HIGH PRESSURE WILL PREVAIL ACROSS THE CENTRAL/SOUTHERN GREAT
PLAINS WHILE A COLD FRONT PROGRESSES EASTWARD ACROSS THE EAST
COAST/SOUTHEAST. A SECOND COLD FRONT WILL SIMULTANEOUSLY MOVE
SOUTHWARD ACROSS THE NORTHERN GREAT PLAINS.
..PORTIONS OF THE SOUTHERN HIGH PLAINS
A TIGHTENED SURFACE PRESSURE GRADIENT BETWEEN THE AFOREMENTIONED
SURFACE HIGH OVER THE CENTRAL GREAT PLAINS AND LOW PRESSURE ACROSS
THE GULF OF CALIFORNIA WILL PROMOTE SUSTAINED 15-20 MPH
SOUTH-SOUTHEASTERLY RETURN FLOW ACROSS THE SOUTHERN HIGH PLAINS.
WITH NO APPRECIABLE MOISTURE RETURN AND ONLY LIMITED MID/HIGH CLOUD
COVER EXPECTED, DIURNAL HEATING/MIXING ARE FORECAST TO RESULT IN RH
VALUES DROPPING TO 10-20% ACROSS THE SAME REGION. WITH CURRENT FUEL
CONDITIONS ACROSS PORTIONS OF THE SOUTHERN HIGH PLAINS SOME OF THE
DRIEST WITHIN THE CONUS, THIS COMBINATION OF WINDS AND RH IS
EXPECTED TO PROMOTE ELEVATED FIRE WEATHER CONDITIONS FOR AT LEAST A
FEW HOURS THIS AFTERNOON. FARTHER SOUTH ACROSS EXTREME SOUTHEASTERN
NEW MEXICO AND PORTIONS OF WEST TEXAS, GREATER MID/HIGH CLOUD COVER
SHOULD RESULT IN RH VALUES REMAINING MORE MARGINAL. WHILE LOCALLY
ELEVATED FIRE WEATHER CONDITIONS REMAIN POSSIBLE ACROSS THIS AREA,
THE MORE MARGINAL FORECAST RH VALUES COUPLED WITH GREATER
UNCERTAINTY REGARDING WIND SPEED DURATION AND MAGNITUDE PRECLUDE A
SOUTHWARD EXPANSION OF ELEVATED HIGHLIGHTS AT THIS TIME.
