AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WAKEFIELD VA
411 PM EDT WED AUG 1 2012

.SYNOPSIS...
SCATTERED SHOWERS AND THUNDERSTORMS WILL CONTINUE THIS AFTERNOON AS
A DISTURBANCE MOVES THROUGH THE REGION. THE PERSISTENT UPPER LEVEL
TROUGH WILL BREAK DOWN AND LIFT NORTHEAST THURSDAY AND
FRIDAY...BRINGING SLIGHTLY HOTTER CONDITIONS AND LOWER CHANCES FOR
PRECIPITATION.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
SFC BOUNDARY SLOWLY WASHING OUT ACROSS THE EASTERN SHORE/SE VA/NE
NC. NEGATIVELY TILTED TROUGH AXIS LOCATED ACROSS EASTERN VA WITH
VORT MAX ROUNDING BASE OF TROUGH ACROSS DELMARVA. BLENDED PRECIP
WATERS STILL AROUND 1.8 INCHES. THE COMBINATION OF THESE FEATURES
HAS ALLOWED FOR ISOLATED/SCATTERED SHOWERS AND THUNDERSTORMS THIS
AFTERNOON ACROSS THE EASTERN ZONES. A FEW OF THESE STORMS WERE ABLE
TO CROSS THE AFOREMENTIONED BOUNDARY CREATING A BRIEF SPIN UP OF A
COUPLE OF WATERSPOUTS. DUE TO WEAK FLOW/WEAK SHEAR...WIDESPREAD
ORGANIZED CONVECTION HAS BEEN LIMITED. WITH THE MAIN ENERGY PUSHING
OFFSHORE...EXPECT ONLY ISOLATED SHOWERS/THUNDERSTORMS THE NEXT FEW
HOURS IN THIS AREA. BEHIND THE FRONT...SFC HIGH PRESSURE HAS HELPED
KEEP SKIES CLEAR/PARTLY CLOUDY ALLOWING TEMPERATURES TO REACH THE
MID/UPPER 80S TO LOW 90S IN SOME AREAS. WHILE LOCATIONS THAT HAVE
BEEN UNDER CLOUD COVER/SHOWERS MUCH OF THE DAY ARE IN THE UPPER
70S/LOW 80S.

SECONDARY SHORTWAVE/VORT MAX LOCATED ACROSS NORTHERN KY AND ROUNDING
THE BASE OF THE TROUGH ATTM HAS INITIATED CONVECTION ACROSS THE
HIGHER TERRAIN IN WV/WESTERN VIRGINIA. SFC BOUNDARY ALSO APPROACHING
THE AREA FROM THE NORTH. COMBINATION OF MID LEVEL DYNAMICS AND LEE
SIDE TROUGHING SHOULD BE ADEQUATE TO KEEP ISOLATED/SCATTERED
SHOWERS/THUNDERSTORMS IN THE GRIDS THE REST OF THE
AFTERNOON/EVENING. THE QUESTION WILL BE HOW MUCH MOISTURE WILL
REMAIN FURTHER WEST. LEE SIDE OF MOUNTAINS DEWPOINTS CURRENTLY
MID/UPPER 60S WITH PRECIP WATERS AROUND 1.5 INCHES. CAPE VALUES
1500-2K J/KG ALSO EXIST ACROSS THIS REGION. AGAIN...DUE TO WEAK
FLOW/SHEAR...THE MAIN THREATS WILL BE LOCALLY HEAVY RAINFALL.
EXPECT ACTIVITY TO COME TO AN END LATE TONIGHT AS TROUGH AXIS
PUSHES EAST.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH SATURDAY/...
AFTER SEVERAL DAYS OF PERSISTENT EAST COAST UPPER TROUGH...THE
TROUGH WILL FINALLY DEAMPLIFY AND LIFT NORTHEAST THURSDAY. SFC HIGH
PRESSURE WILL BUILD INTO THE OH RIVER VALLEY BRINGING IN DRIER AND
WARMER CONDITIONS. HOWEVER...LEE SIDE TROUGHING THURSDAY INTO
FRIDAY MAY BE FOCUS OF A HIGHER PROBABILITY OF AFTERNOON/EVENING
CONVECTION. IN ADDITION...LIGHT SYNOPTIC FLOW WILL ALLOW FOR THE
POSSIBILITY OF SEA BREEZE INTERACTION/THUNDERSTORMS. TEMPERATURES
WILL REBOUND TO MORE SUMMER LIKE TEMPERATURES WITH DAYTIME
READINGS THURSDAY/FRIDAY GENERALLY UPPER 80S CLOSER TO THE COAST
AND LOW/MID 90S ELSEWHERE.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...

PERIOD. HOT/VRY WRM AND HUMID CONDITIONS WILL BE THE RULE ACRS THE
AREA SAT NGT INTO MON...AS SFC HI PRES REMAINS OFF THE MID ATLC CST

60S TO LWR 70S TUE AND WED MORNGS. MAX TEMPS WILL BE IN THE UPR 80S
TO LWR 90S SUN AND MON...AND IN THE MID 80S TO NEAR 90 TUE AND WED.
