AREAS AFFECTED...PORTIONS OF THE MID-ATLANTIC COASTAL STATES
CONCERNING...SEVERE THUNDERSTORM WATCH 474...
VALID 092306Z - 100030Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 474
CONTINUES.
SUMMARY...THE THREAT FOR DAMAGING WINDS CONTINUES ACROSS WW 474 AS A
LINE OF STRONG TO SEVERE THUNDERSTORMS MOVES EASTWARD, AND
EVENTUALLY, OFFSHORE. THUNDERSTORM WIND GUSTS OF 55-70 MPH REMAIN
POSSIBLE.
DISCUSSION...LINEAR CONVECTION WITHIN WW 474 CONTINUES TO MOVE
EAST-SOUTHEAST ACROSS THE MID-ATLANTIC COASTAL STATES AND WILL
CONTINUE TO POSE A HAZARD FOR DAMAGING STRAIGHT-LINE WIND GUSTS.
SUFFICIENT BUOYANCY AND DEEP-LAYER SHEAR WILL CONTINUE TO SUPPORT
LINEAR BOWING SEGMENTS BEFORE ULTIMATELY MOVING OFFSHORE INTO THE
ATLANTIC. THE BEST SHORT-TERM CORRIDOR FOR DAMAGING WIND GUSTS
APPEARS TO BE ACROSS PORTIONS OF VIRGINIA AND MARYLAND, WHERE THE
COMBINATION OF MLCAPE AND DEEP-LAYER SHEAR IS BEST MAXIMIZED AND
CURRENT RADAR TRENDS SUGGEST THE STRONGEST UPDRAFTS HAVE DEVELOPED.
