.DISCUSSION...TIGHTENING SURFACE PRESSURE GRADIENTS WILL CAUSE
INCREASING WINDS BEHIND A COLD FRONT THAT SWEPT ACROSS THE AREA LAST
NIGHT. THE PRECIPITATION WITH THIS FRONT HAS ENDED AND MOVED TO THE
EAST. THE GENERAL TREND THROUGH THE DAY WILL BE GRADUALLY DRYING
WITH MORE STABLE AIR AS WEAK HIGH PRESSURE BUILDS IN...HOWEVER WINDS
WILL BE BREEZY UNTIL SUNSET FROM THE WEST TO NORTHWEST...AND WILL BE
SLIGHTLY INCREASED ON TUESDAY AS WELL.
