VALID 191200Z - 201200Z  
   
..NO CRITICAL AREAS
 
 
   
..SYNOPSIS
 
 
MID-LEVEL RIDGING OVER THE WESTERN US IS FORECAST TO MOVE EASTWARD  
AS THE OVERALL UPPER-AIR PATTERN BECOMES MORE AMPLIFIED. HIGH  
PRESSURE OVER THE GREAT BASIN WILL MOVE INTO THE ROCKIES AS A COLD  
FRONT MOVES SOUTH OVER THE CENTRAL US. ASIDE FROM SOME RESIDUAL  
OFFSHORE FLOW OVER PARTS OF SOUTHERN CA, WIDESPREAD FIRE-WEATHER  
CONCERNS ARE NOT EXPECTED.  
   
..SOUTHERN CA
 
 
OFFSHORE PRESSURE GRADIENTS AND THE RESULTING SURFACE WINDS ARE  
EXPECTED TO GRADUALLY WEAKEN EARLY THIS MORNING AS HIGH PRESSURE  
SHIFTS EASTWARD OVER THE ROCKIES AND GREAT BASIN. WHILE WINDS SHOULD  
GENERALLY WEAKEN, SOME LINGERING, LOCALLY ELEVATED FIRE-WEATHER  
CONDITIONS MAY CONTINUE IN THE FOOTHILLS OF LOS ANGELES AND VENTURA  
COUNTIES THROUGH THE FIRST HALF OF THE AFTERNOON. LIMITED IN SPATIAL  
COVERAGE AND DURATION, FIRE-WEATHER CONCERNS ARE NOT EXPECTED TO BE  
WIDESPREAD. FIRE-WEATHER CONCERNS WILL END AS ONSHORE FLOW RETURNS  
THIS EVENING.  
   
..CENTRAL PLAINS
 
 
A MODERATELY STRONG DOWNSLOPE WIND EVENT BEHIND THE DEEPENING  
SHORTWAVE TROUGH WILL ALLOW FOR STRONG GUSTS OF 30-40 MPH ACROSS  
PARTS OF EASTERN CO AND WESTERN NE/KS THIS AFTERNOON. HOWEVER, THESE  
WINDS ARE ONLY EXPECTED TO OVERLAP WITH COOLER SURFACE TEMPERATURES  
AND MODERATELY LOW RH FOR A FEW HOURS. WHILE SOME LOCALLY ELEVATED  
FIRE-WEATHER CONDITIONS ARE POSSIBLE, THE LACK OF DRIER FUELS AND  
THE LIMITED OVERLAP OF DRY/WINDY CONDITIONS SHOULD NEGATE MORE  
WIDESPREAD FIRE-WEATHER POTENTIAL.
