..SUMMARY
 
 
SPORADIC LIGHTNING FLASHES MAY OCCUR THIS AFTERNOON AND EVENING OVER  
THE COASTAL PACIFIC NORTHWEST INTO INTERIOR NORTHERN CALIFORNIA.  
SEVERE WEATHER IS NOT EXPECTED.  
   
..PACIFIC NORTHWEST
 
 
UPPER RIDGE WILL SHIFT EAST INTO THE ROCKIES LATER THIS AFTERNOON AS  
A STRONG TROUGH ADVANCES INLAND ALONG THE PACIFIC NORTHWEST. LATEST  
GUIDANCE SUGGESTS 120-150M, 12HR HEIGHT FALLS WILL OVERSPREAD THIS  
REGION, COINCIDENT WITH HIGHLY DIFFLUENT FLOW ALOFT. VERY COLD  
MID-LEVEL TEMPERATURES, AND COOLING/STEEPENING LAPSE RATES FAVOR AN  
INCREASINGLY BUOYANT PROFILE BY AFTERNOON WITHIN THE POST-FRONTAL  
ENVIRONMENT. SCATTERED CONVECTION SHOULD DEVELOP WITHIN THIS  
ENVIRONMENT, AND THE STRONGEST UPDRAFTS MAY PENETRATE LEVELS  
NECESSARY FOR LIGHTNING DISCHARGE, HENCE THE CONTINUATION OF THUNDER  
PROBABILITIES.
