TROUGH ALONG THE EAST COAST CONTINUES TO PROGRESS EASTWARD WITH A  
RIDGE AXIS ACROSS WEST TN MOVING EASTWARD TOWARD OUR FORECAST  
AREA ON WEDNESDAY. THIS IS PLACING THE STRONGEST SUBSIDENCE JUST  
TO OUR EAST WITH AN INCREASE IN MID AND HIGH LEVEL CLOUDS LATE  
TONIGHT AND WEDNESDAY. STILL, EXPECT A PLEASANT DAY WITH MAX  
TEMPERATURES WITHIN A FEW DEGREES OF NORMAL. WITH RIDGING OVER THE  
AREA AND SURFACE HIGH PRESSURE JUST TO THE EAST, ALSO EXPECT VERY  
LOW CHANCES OF PRECIP WITH THE MAIN SLIGHT CHANCE POPS ACROSS THE  
WESTERN PORTIONS OF THE FORECAST AREA AND ALONG THE HIGHER  
ELEVATIONS.  
 
ONLY MADE MINOR ADJUSTMENT TO THE FORECAST TO REFLECT CURRENT  
CLOUDS AND TRENDS AS WELL AS CURRENT TEMPERATURES AND DEW POINTS.  
KEPT PATCHY FOG IN THE GRIDS WITH THE BEST CHANCE FOR DENSE AREAS  
OF FOG ACROSS NE TN AND SW VA IN THOSE FAVORED RIVER VALLEYS.
