.DISCUSSION...

THE DRIER AIR HAS ARRIVED OVER THE NORTHERN HALF OF ALABAMA LATE
THIS EVENING. LOW TO MID 60S DEWPOINTS ARE NOW BEING OBSERVED WITH
VERY HUMID DEWPOINTS REMAINING ACROSS THE SOUTHERN HALF OF THE
STATE. THE DRY AIR WILL EVENTUALLY FILTER SOUTHWARD OVERNIGHT
TONIGHT AS THE COLD FRONT SLOWLY PUSHES SOUTH OF CENTRAL ALABAMA.
IT WILL CERTAINLY MAKE A DIFFERENCE IN HOW HUMID IT WILL FEEL
OVERNIGHT TONIGHT AND DURING THE DAY ON FRIDAY...EVEN THOUGH
TEMPERATURES WILL ONLY BE A FEW DEGREES COOLER. HAVE ADJUSTED POPS
DOWNWARD THROUGH THE OVERNIGHT TO REMOVE ALL MENTION OF WEATHER
FOR MUCH OF CENTRAL ALABAMA. THE ONLY EXCEPTION WILL BE ACROSS THE
FAR SOUTHEASTERN COUNTIES WHERE AN ISOLATED SHOWER WILL STILL BE
POSSIBLE JUST AHEAD OF THE SURFACE FRONT. SKIES SHOULD CLEAR
NICELY TONIGHT FOR FOLKS TO ENJOY THE "BLUE MOON" AND THE LESS
HUMID CONDITIONS. UPDATES ARE OUT.

FRIDAY...NORTHERLY WINDS OF 8-12 KNOTS WILL HELP PUSH THE FRONT TO
