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.
