MODELS REMAIN IN GOOD AGREEMENT ON BIG PICTURE IN THE LONG TERM
PERIOD...WHICH IS STILL FAIRLY ACTIVE. THE BLOCKING HIGH WELL
OFFSHORE THE MIDATLANTIC COAST LOOKS TO RETROGRADE TO THE
CAROLINAS TOWARDS THE WEEKEND...AS AMPLIFIED TROUGH STRETCHING
FROM NORTHWEST GREAT LAKES TO MIDWEST WEAKENS. OUR AREA REMAINS IN
THE BUSY WAVE-RIDDLED FLOW BETWEEN THE TWO FEATURES. THIS STARTS
WITH VERY MOIST SSW AND PRECIPITABLE WATER STILL AROUND 2 INCHES
THURSDAY...AND GRADUALLY TRANSITIONS TO MORE OF A WESTERLY FLOW
RIDING OVER THE TOP OF THE LARGE UPPER HIGH INTO THE WEEKEND.
LIKELY MORE OF A SOUTH-TO-NORTH GRADIENT IN PRECIPITABLE WATER
VALUES BY THEN...AVERAGING AROUND AN INCH-AND-A-HALF /HIGHER
SOUTH/. MAINLY DIURNALLY DRIVEN CHANCES OF SHOWERS AND
THUNDERSTORMS WILL CONTINUE THROUGH THE PERIOD...BUT HIGHEST

TEMPERATURES THROUGH THE PERIOD ABOVE CLIMATOLOGY FOR LOWS DUE TO
MOIST DEWPOINTS...AND NEAR OR SLIGHTLY ABOVE CLIMATOLOGY FOR
HIGHS. WITH WIND FIELDS THROUGH THE ATMOSPHERIC COLUMN GENERALLY
NOT VERY SUPPORTIVE OF SEVERE CONVECTION...THE MAIN CONCERN WITH
VERY WET GROUND WILL CONTINUE TO BE LOCALIZED FLOODING WHERE
REPEATED SHOWERS AND THUNDERSTORMS OCCUR.

.AVIATION /16Z SUNDAY THROUGH THURSDAY/...
700 AM EDT UPDATE...
DENSE FOG AND A LOW STRATUS DECK HAS DEVELOPED THIS MORNING AS
EXPECTED. EXPECT THIS TO QUICKLY MIX OUT WITHIN THE NEXT COUPLE
HOURS. VFR CONDITIONS WILL RETURN THIS AFTERNOON AHEAD OF THE NEXT
ROUND OF SHOWERS AND THUNDERSTORMS.

ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS ARE EXPECTED DURING THE
AFTERNOON HOURS ON TODAY. INSTABILITY WILL INCREASE ALONG WITH
STRONGER UPPER LEVEL SUPPORT. THIS COMBINATION WILL RESULT IN
SCATTERED THUNDERSTORMS ACROSS THE REGION. HAVE MENTIONED
THUNDERSTORMS IN THE TAF FROM 17 TO 21Z. CONFIDENCE IS HIGHEST
DURING THIS TIME DUE TO PRIME AFTERNOON HEATING. STORMS MAY CONTINUE
THROUGH THE LATE AFTERNOON/EVENING HOURS...HOWEVER CONFIDENCE IS
NOT HIGH...THUS WILL NOT PREVAIL IN TAF. AFTER THESE STORMS MOVE
OUT OF THE REGION...FOG AND STRATUS IS EXPECTED TO DEVELOP AGAIN
WITH SIMILAR CONDITIONS AS SUNDAY MORNING.
