DISCUSSION:
TRW ACTIVITY GOING STRONG IN LOWER MARYLAND COUNTIES WITH COPIOUS
RAINFALL. NOT A LOT OF DYNAMIC FORCES AT WORK ELSEWHERE ACCORDING TO
THE MODELS...MAINLY INSTABILITY ACROSS THE REGION TO FIRE THIINGS OFF
AFTER SOME WARMING. STILL WATCHING SE VIRGINIA AND NE NORTH CAROLINA
FOR DEVELOPMENT GIVEN OLD BOUNDARIES FROM THIS MORNING. FEEL SITUATION
WARRANTS AT LEAST 30 POPS MOST OF WESTERN CWA...WITH 40 TO 60 EAST FOR
THIS EVENING. WITH NO SIGNIFICANT FORCING MECHANISMS MOST ACTIVITY
SHOULD DIE OFF AFTER SUNSET. EXPECTED LIGHT WIND FIELD FOR TONIGHT
BODES WELL FOR FOG...SOME LIKELY TO BE DENSE. SOME COOLER AND DRIER AIR
ALOFT FOR TOMORROW...WHILE SURFACE LOW MOVES OFF COAST AND HIGHER
PRESSURE MOVES IN FROM THE WEST. HOWEVER THE UPPER TROF APPEARS TO MOVE
THROUGH TOMORROW MORNING WHICH MAY PROVIDE SOME IMPETUS TO KICK
SOMETHING OFF. EITHER WAY THOUGH LOOKS TO BE A RATHER CLOUDY AND
UNSEASONABLY COOL DAY ONCE AGAIN WITH THE HOPE FOR SOME PEEKS OF
AFTERNOON SUN. OTHERWISE MODELS SHOW AT LEAST WEAK DOWNWARD MOTION AFTER
24 HOURS.

NO PROBLEMS WITH MARINE INTERESTS.
