...NO SVR TSTM AREAS FORECAST...

...SOUTH ATLANTIC COAST...
SOUTHERN PERIPHERY OF WEAKENING LARGE-SCALE TROUGH HAS SHIFTED EAST
OF THE SOUTH CENTRAL APPALACHIANS...AND IS EXPECTED TO PROGRESS OFF
SOUTHERN MID ATLANTIC COASTAL AREAS EARLY THIS EVENING.  FORCING MAY
STILL EVENTUALLY SUPPORT SCATTERED THUNDERSTORMS.  BUT...THE
BOUNDARY LAYER OVER THE COASTAL WATERS IS STILL IN THE PROCESS OF
MODIFYING...AND IT APPEARS MOST LIKELY THAT THIS WILL OCCUR WELL
OFFSHORE...PROBABLY NEAR THE GULF STREAM.

...PACIFIC NORTHWEST...
INCREASINGLY ANTICYCLONIC FLOW IS DEVELOPING NORTHEASTWARD TOWARD  
THE NORTHERN PACIFIC COAST...AND RISK OF THUNDERSTORMS ALREADY
APPEARS TO BE DIMINISHING.  POTENTIAL IS EXPECTED TO BECOME
NEGLIGIBLE BY THE 14/00-03Z TIME FRAME...AS LOW-LEVEL ONSHORE FLOW
WEAKENS AND TEMPERATURES IN THE LOWER/MID TROPOSPHERE WARM...
STABILIZING LAPSE RATES.
