DAY 1 FIRE WEATHER OUTLOOK  
NWS STORM PREDICTION CENTER NORMAN OK  
0124 AM CST WED NOV 29 2017  
 
VALID 291200Z - 301200Z  
   
..SYNOPSIS
 
 
A PERSISTENT OFFSHORE GRADIENT IN AREAS OF SOUTHERN CALIFORNIA WILL  
EXIST ON THE SOUTHERN PERIPHERY OF A HIGH PRESSURE ACROSS IDAHO/UTAH  
- RESULTING IN AREAS OF ELEVATED FIRE WEATHER. FARTHER NORTHEAST, A  
SHARPENING SURFACE TROUGH WILL MIGRATE QUICKLY EASTWARD ACROSS THE  
DAKOTAS DURING PEAK HEATING AND RESULT IN LOCALLY ELEVATED FIRE  
WEATHER CONDITIONS, ALTHOUGH RH VALUES ARE STILL EXPECTED TO BE A  
BIT TOO HIGH TO JUSTIFY ANY DELINEATION IN THAT AREA.  
   
..COASTAL RANGES OF SOUTHERN CALIFORNIA
 
 
THE AFOREMENTIONED SURFACE PRESSURE GRADIENT WILL RESULT IN AREAS OF  
GUSTY WINDS DURING THE MORNING AND MIDDAY HOURS. 15-20 MPH  
NORTHEASTERLY WINDS WILL BECOME COMMON, WITH AREAS OF 30-35+ MPH  
GUSTS IN TERRAIN-FAVORED AREA. THIS GRADIENT MAY SLACKEN SOME  
DURING PEAK-HEATING HOURS, LEADING TO A LESSENING OF WIND GUSTS  
CONCURRENT TO FALLING RH THAT WILL APPROACH CRITICAL THRESHOLDS.  
OVERNIGHT RECOVERY IS EXPECTED TO REMAIN POOR, AND A FEW STRONGER  
GUSTS WILL REMAIN POSSIBLE OVERNIGHT AS THE OFFSHORE GRADIENT  
PERSISTS. THESE CONDITIONS ARE CONSISTENT WITH ELEVATED FIRE  
WEATHER CRITERIA, AND AN ATTENDANT DELINEATION REMAIN IN PLACE FOR  
THIS OUTLOOK.
