AGREES WELL WITH THE MESO ETA...WHICH SHOWS -14 DEG C THIS

EVEN A THUNDERSTORM THIS AFTERNOON. HOWEVER...ATMOSPHERE IS NOT VERY
MOIST...ONLY .90 PW. CURRENT AREA OF LIGHT SHOWERS MOVING ACROSS
RALEIGH SEEMS TO BE WEAKENING...HOWEVER...SHOWER AREA MAY EXPAND A
BIT AS THEY MOVE EAST INTO CLEAR AREAS CURRENTLY RECEIVING GOOD
INSOLATION. WILL KEEP 30 POPS...AS DO NOT EXPECT COVERAGE TO BE
WIDESPREAD...OR LAST VERY LONG OVER ONE AREA. HIGHS ONLY IN THE
LOWER 80S LOOKS ON TRACK TODAY.

SWELLS FROM ALBERTO COULD AGAIN CAUSE SOME MINOR OCEAN OVERWASH AT
HIGH TIDE TODAY FOR THE OUTER BANKS...AND ALSO RESULT IN DANGEROUS
