DAY 2 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0150 AM CDT TUE SEP 24 2019
VALID 251200Z - 261200Z
..SYNOPSIS
AN UPPER LOW CENTERED OVER THE NORTHERN BAJA PENINSULA IS FORECAST
TO GRADUALLY WEAKEN ON WEDNESDAY. UPPER TROUGHING WILL PERSIST OVER
THE NORTHERN/CENTRAL PLAINS INTO THE UPPER MIDWEST AND GREAT LAKES.
SURFACE RIDGING EXTENDING FROM THE PACIFIC NORTHWEST INTO THE GREAT
BASIN SHOULD WEAKEN THROUGH THE PERIOD.
..PORTIONS OF NORTHERN CALIFORNIA
ALTHOUGH MID/UPPER-LEVEL WINDS WILL BE WEAKER ACROSS NORTHERN CA
COMPARED TO DAY 1/TUESDAY, THERE SHOULD STILL BE ENOUGH OF A SURFACE
PRESSURE GRADIENT ACROSS THIS REGION TO SUPPORT STRONG/GUSTY
NORTH-NORTHEASTERLY WINDS WEDNESDAY MORNING AND PERHAPS THE EARLY
AFTERNOON. THIS WILL ESPECIALLY BE THE CASE IN THE HIGHER TERRAIN OF
THE COASTAL RANGES, WHERE SUSTAINED WINDS OF 15-20 MPH MAY COMBINE
WITH RH VALUES LOWERED TO AROUND 20%. THESE METEOROLOGICAL
CONDITIONS ALONG WITH CONTINUED RECEPTIVE FUELS SUPPORT AN ELEVATED
DELINEATION ACROSS PORTIONS OF NORTHERN CA.
..PORTIONS OF SOUTHERN CALIFORNIA
LOCALLY STRONG/GUSTY OFFSHORE WINDS AROUND 15-20 MPH MAY CONTINUE
EARLY WEDNESDAY MORNING FOR A FEW HOURS, AS A MODESTLY ENHANCED
SURFACE PRESSURE GRADIENT REMAINS ACROSS PARTS OF SOUTHERN CA. RH
RECOVERY FROM LATE TUESDAY NIGHT INTO WEDNESDAY MORNING SHOULD
REMAIN POOR, WITH VALUES OF 15-20% COMMON. ELEVATED CONDITIONS
APPEAR MOST PROBABLE ACROSS THE MOUNTAINS/PASSES OF SANTA BARBARA,
VENTURA, AND LOS ANGELES COUNTIES. THE SURFACE PRESSURE GRADIENT
WILL LIKELY WEAKEN THROUGH THE DAY, LEADING TO A GRADUAL REDUCTION
IN WIND SPEEDS.
