RAISED DEW POINT TEMPERATURES SEVERAL DEGREES ESPECIALLY SOUTH WHERE READINGS ARE IN THE LOWER TO MID 70S THIS MORNING AS LOW LEVEL MOISTURE HAS INCREASED. MOS GUIDANCE FOR DEW POINTS HAVE BEEN TOO LOW SLAST SEVERAL DAYS SO HAVE INSERTED NAM GUIDANCE AND THEN LOWERED SOME SO THAT DEW POINTS WOULD BE MORE REPRESENTATIVE. UPDATED FORECAST AS HEAT INDEX TEMPERATURES COULD REACH OVER 100 IN THE SOUTHERN VALLEY AND LOWER ELEVATIONS OF THE SOUTHERN PLATEAU COUNTIES THIS AFTERNOON...UNLESS ENOUGH MIXING OCCURS. SHORT RANGE MODELS AGAIN SHOW SHOWERS AND STORMS DEVELOPING AROUND 20-21Z IN SOUTHEAST TN AND SOUTHWEST NORTH CAROLINA THEN LASTING WELL INTO THE EVENING.
