...NO SVR TSTM AREAS FORECAST...

PROGRESSIVE IMPULSES...EMBEDDED WITHIN STRONGER BELTS OF WESTERLIES
EMANATING FROM THE NORTHEAST AND EAST CENTRAL PACIFIC...ARE
BEGINNING TO SUPPORT NORTHEASTWARD ACCELERATION OF CENTRAL U.S.
CYCLONE AND ASSOCIATED UPPER TROUGH.  LATTER FEATURES ARE PROGGED
INTO EASTERN CANADA AND THE LOWER GREAT LAKES REGION BY 12Z
WEDNESDAY...BEFORE CONTINUING TO WEAKEN AND LIFT THROUGH WESTERN
PERIPHERY OF UPPER RIDGE OFF THE ATLANTIC SEABOARD.  IN THEIR
WAKE...MODELS SUGGEST POLAR LOW WILL TURN MORE RAPIDLY SOUTHWARD
THROUGH MANITOBA.  SOME PHASING OF THIS FEATURE IS PROGGED WITH A
SHORT WAVE TROUGH DIGGING EAST SOUTHEASTWARD OUT OF THE NORTHERN
ROCKIES INTO THE MID/UPPER MISSISSIPPI VALLEY. THIS WILL BE
ACCOMPANIED BY ANOTHER SIGNIFICANT COLD INTRUSION INTO MUCH OF THE
NORTH CENTRAL STATES BY 12Z THURSDAY.

A SURFACE FRONTAL PASSAGE...ASSOCIATED WITH CENTRAL U.S. CYCLONE OF
THE PAST SEVERAL DAYS...WILL HAVE ALREADY PROGRESSED THROUGH ALL BUT
NEW ENGLAND AND THE FLORIDA PENINSULA BY 12Z.  STABILIZATION IN ITS
WAKE IS EXPECTED TO PRECLUDE RISK OF DEEP CONVECTION THIS PERIOD
WESTWARD THROUGH THE ROCKIES.

FARTHER WEST...WARM ADVECTION PRECIPITATION...AHEAD OF PHASING
NORTHERN AND SOUTHERN STREAM IMPULSES OVER THE EASTERN PACIFIC...IS
PROGGED INTO THE NORTH CENTRAL PACIFIC COAST LATE WEDNESDAY/
WEDNESDAY NIGHT.  HOWEVER...MAIN UPPER COLD POOL IS FORECAST TO
REMAIN WELL OFFSHORE...AND ANY THUNDERSTORM ACTIVITY APPROACHING THE
OREGON/NORTHERN CALIFORNIA COAST SHOULD DIMINISH BEFORE IT SPREADS
INLAND.

...ATLANTIC SEABOARD...
MOIST...POTENTIALLY UNSTABLE BOUNDARY LAYER WILL BE CONFINED TO THE
SOUTHERN FLORIDA PENINSULA BY EARLY WEDNESDAY. COLD FRONT...OR
PRE-FRONTAL WIND SHIFT...COULD PROVIDE A FOCUS FOR CONVECTIVE
INITIATION...BUT IT IS STILL UNCERTAIN WHETHER INHIBITION WILL
BECOME WEAK ENOUGH TO ALLOW ANYTHING OTHER THAN AN ISOLATED WEAK
THUNDERSTORM OR TWO.
