NWS STORM PREDICTION CENTER NORMAN OK  
0148 AM CST SAT NOV 18 2017  
 
VALID 181200Z - 191200Z  
   
..SYNOPSIS
 
 
A STRONG MID-LEVEL TROUGH WILL CONTINUE TO MOVE ACROSS THE UNITED  
STATES TODAY. IN THE WAKE OF THIS TROUGH, COOLER AND DRIER  
CONDITIONS WILL OVERSPREAD MUCH OF THE WESTERN TWO-THIRDS OF THE  
UNITED STATES AS A SURFACE HIGH PRESSURE MOVES INTO THE GREAT BASIN.  
THE POSITION OF THE HIGH WILL RESULT IN NORTH/NORTHEASTERLY WINDS  
ACROSS PORTIONS OF SOUTHERN CALIFORNIA BOTH THIS MORNING AND SUNDAY  
MORNING, WITH A DIURNALLY DRIVEN DECREASE IN WINDS IN BETWEEN. THE  
OFFSHORE FLOW WILL RESULT IN ELEVATED FIRE-WEATHER CONDITIONS  
PRIMARILY ACROSS THE MOUNTAINS OF SANTA BARBARA, VENTURA, AND LOS  
ANGELES COUNTIES.  
 
ELSEWHERE, STRONG GUSTY NORTHERLY WINDS WILL OVERSPREAD PORTIONS OF  
THE SOUTHERN PLAINS IN THE WAKE OF A SURFACE COLD FRONT. COOLER  
CONDITIONS WILL RESULT IN SLIGHTLY HIGHER RELATIVE HUMIDITY TODAY AS  
COMPARED TO FRIDAY. THE HIGHER RELATIVE HUMIDITY AND COOLER  
CONDITIONS SHOULD LIMIT THE OVERALL FIRE-WEATHER THREAT DESPITE THE  
STRONG, GUSTY SURFACE WINDS.
