DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0218 AM CDT THU APR 03 2008
VALID 051200Z - 061200Z
..THERE IS A SLGT RISK OF SVR TSTMS FROM FAR ERN GA NEWD INTO SERN
VA...
..SYNOPSIS...
UPPER TROUGH MOVING THROUGH THE TN AND LOWER MS VALLEYS ON FRIDAY IS
FORECAST TO WEAKEN AND LIFT ENEWD INTO THE MID ATLANTIC STATES ON
SATURDAY...AS ANOTHER TROUGH DEEPENS OVER THE NRN/CENTRAL PLAINS.
ASSOCIATED COLD FRONT IS EXPECTED TO STRETCH FROM DELMARVA SWWD INTO
SRN AL EARLY IN THE PERIOD...BUT SHOULD MOVE MOSTLY OFF THE SRN/MID
ATLANTIC COAST BY LATE IN THE DAY.
..SRN/MID ATLANTIC STATES...
WEAK LAPSE RATES/INSTABILITY SHOULD RESULT IN A BAND OF CONVECTION
..ALONG/AHEAD OF THE FRONT...TO BE MOSTLY NON-SEVERE DURING THE
MORNING HOURS. ALTHOUGH RESIDUAL CLOUDS MAY REDUCE THE AMOUNT OF
SOLAR RADIATION SOMEWHAT...SUFFICIENT WARMING IS EXPECTED FROM THE
NRN FL PANHANDLE NEWD INTO SERN VA PRIOR TO FROPA. EFFECTIVE SHEAR
AT 30-40 KT AND MLCAPES NEAR 1000 J/KG SHOULD SUPPORT A FEW SEVERE
STORMS. UNIDIRECTIONAL SWLY WINDS AND RELATIVELY STRONG
ENVIRONMENTAL WINDS FAVOR DAMAGING WINDS AS THE PRIMARY THREAT. THE
COMBINATION OF MORE WARMING/INSTABILITY AND GREATER MASS
CONVERGENCE/LARGE SCALE LIFTING SUGGESTS THE HIGHEST THREAT FOR
SEVERE STORMS WILL EXIST FROM FAR ERN GA NEWD INTO SERN VA DURING
THE AFTERNOON HOURS.
