...NO SVR TSTM AREAS FORECAST...

...SUMMARY...
SCATTERED SHOWERS AND ISOLATED THUNDERSTORMS ARE POSSIBLE SATURDAY
OVER COASTAL REGIONS OF NORTHERN CALIFORNIA AND OREGON.

...SYNOPSIS...
A POTENT MID-LEVEL TROUGH OVER THE ERN PACIFIC WILL MOVE ASHORE THE
WRN U.S. AND INTO THE NWRN QUARTER OF THE CONUS DURING THE DAY 3
PERIOD.  DOWNSTREAM OVER THE UPPER MIDWEST AND UPPER GREAT LAKES...A
STRONG SPEED MAXIMA WILL QUICKLY MOVE TO THE LOWER GREAT LAKES AND
NORTHEAST U.S. WHILE A TROUGH OFF THE CAROLINAS MOVES FARTHER E INTO
THE ATLANTIC.

AN AREA OF SURFACE LOW PRESSURE WILL MOVE INTO THE PACIFIC NW STATES
FROM THE SW WHILE A LEE TROUGH DEVELOPS OVER THE NRN AND CNTRL HIGH
PLAINS.  MEANWHILE FARTHER E...SURFACE HIGH PRESSURE WILL LEAD TO
TRANQUIL CONDITIONS OVER MUCH OF THE CNTRL U.S. INTO THE SOUTHEAST.
A COLD FRONT IS FORECAST TO MOVE ACROSS THE LOWER GREAT LAKES AND
INTO THE NORTHEAST.

...NRN CA/ORE COAST...
COOL MID-LEVEL TEMPS ASSOCIATED WITH THE APPROACHING TROUGH WILL
LIKELY SUPPORT CHARGE SEPARATION WITH THE STRONGEST CONVECTIVE
ELEMENTS FROM MAINLY THE COASTAL REGION OF NRN CA INTO ORE.  DESPITE
THE PRESENCE OF AN INCREASINGLY STRONG WIND PROFILE...ONLY POCKETS
OF WEAK BUOYANCY ARE LIKELY TO DEVELOP AND WILL LIMIT UPDRAFT
STRENGTH WITH PERHAPS THE STRONGEST UPDRAFT OR TWO BEING CAPABLE OF
SMALL HAIL.
