.DISCUSSION...

INSOLATION AND DRIER AIRMASS (SFC HIGH CENTERED OVER W TN/E AR)
BEHIND SFC COLD FRONT MOVING ACROSS THE TN VALLEY HAS DISSIPATED THE
POST QLCS CLOUD COVER AND PATCHY FOG. THUS, HAVE ADJUSTED CLOUD COVER
TO REFLECT MOSTLY SUNNY TO PARTLY CLOUDY CONDITIONS THIS MORNING AND
MOSTLY SUNNY THIS AFTERNOON.

ADDITIONALLY, AIR TEMPERATURES ARE RUNNING A LITTLE WARMER OVER NORTH
ALABAMA (ESPECIALLY OVER NW AL). THUS, HAVE INCREASED FORECAST DAYTIME
HIGH TEMPERATURES OVER NW AL AND PORTIONS OF NORTH CENTRAL AL. AS
MENTIONED PREVIOUSLY, DRIER AIR IS ADVECTING SOUTHWARD TOWARDS THE TN
VALLEY, BUT IS OCCURRING A LITTLE SLOWER THAN ORIGINALLY FORECAST. TO
ACCOUNT FOR THIS CHANGE, HAVE ADJUSTED DEWPOINT TEMPERATURES TO
REFLECT THOSE CHANGES.
