NWS STORM PREDICTION CENTER NORMAN OK
0316 PM CDT SAT JUN 09 2007
AREAS AFFECTED...NC
CONCERNING...HEAVY RAINFALL
VALID 092016Z - 092145Z
HEAVY RAIN...ALONG WITH SOME HAIL...MAY CONTINUE THE NEXT COUPLE OF
HOURS ACROSS ONSLOW AND CARTERET COUNTIES ALONG COASTAL NC.
ALTHOUGH NWLY BOUNDARY LAYER WINDS COVER MOST OF NC...THE SEA BREEZE
HAS PUSHED NWWD ONTO THE COAST. CONVERGENCE ALONG THIS BOUNDARY HAS
RESULTED IN THUNDERSTORMS DEVELOPING DURING THE PAST HOUR. THE
INFLOW FROM THESE STORMS IS FROM THE NW AND THE MID/HIGH WINDS WOULD
SUPPORT THE STORMS MOVING SEWD AT 10-15 KT. HOWEVER... THE BACKWARD
PROPAGATION IS ALMOST EQUAL TO THE MEAN ADVECTIVE FLOW...RESULTING
IN THE STORMS TO REMAIN NEARLY STATIONARY. THE COMBINATION OF A
MODERATELY UNSTABLE AIR MASS...PW VALUES AROUND 2 INCHES AND NEARLY
STATIONARY STORMS WILL RESULT IN LOCALIZED VERY HEAVY RAINFALL.
ALSO...THE STRONG INSTABILITY WILL BE FAVORABLE FOR MARGINALLY
SEVERE HAIL.
