A RELATIVELY WEAK UPPER TROUGH OFFSHORE IS PROGGED TO MOVE ONSHORE
THIS EVENING.  TIMING WILL MINIMIZE SHOWER ACTIVITY SINCE IT COMES IN
TOO LATE TO TAKE ADVANTAGE OF MAXIMUM SURFACE HEATING...BUT IT STILL
MAY KICK OFF SOME EVENING SHOWERS OVER THE MOUNTAINS AND EAST SIDE.

THE TROUGH WILL HANG UP TONIGHT AS IT DIGS IN OVER THE FORECAST
AREA...BUT IT LOOKS LIKE IT WILL SPAWN A CUTOFF LOW TO THE SOUTH AND
THEN SHEAR TO THE EAST OF THE FORECAST AREA BY TOMORROW AFTERNOON.
SO...THE FORECAST AREA WILL BE ON THE NVA SIDE OF THE TROUGH BY MAX
SURFACE HEATING SATURDAY.  THE TROUGH DOES NOT MAKE MUCH EASTWARD
PROGRESS SO A STRONG TRAILING RIDGE WILL REMAIN OFFSHORE...THOUGH IT
MAKES IT PRESENCE FELT WITH INCREASING NORTH WINDS ALOFT ALONG THE
WEST COAST.  THE UPPER LEVEL TRAJECTORIES WOULD SUPPORT A DRY
FORECAST ONCE THE TROUGH MOVES TO THE EAST...ANY SHORT WAVES MOVING
DOWN THE BACKSIDE OF THE TROUGH WOULD BE DRY INSIDE SLIDERS.
MODEL TIME SECTIONS ALL SCREAM DRY AND STABLE AFTER TONIGHT.
HOWEVER...WILL PUT SOME CLOUDS IN THE FORECAST FOR SISKIYOU/MODOC
COUNTIES SATURDAY AFTERNOON/EVENING TO ACCOUNT FOR UNCERTAINTY AS TO
WHERE THE THUNDERSTORMS IN CALIFORNIA WILL DEVELOP ON SATURDAY.

MEANWHILE AT LOW LEVELS...AN OFFSHORE EVENT IS IN THE OFFING
BEGINNING SATURDAY NIGHT AND STRENGTHENING SUNDAY NIGHT.  NOTHING
REALLY DRAMATIC...BUT BROOKINGS WILL GET FAIRLY WARM SUNDAY.  LOOK
FOR AREAS OF MARINE STRATUS TO BE AROUND SATURDAY MORNING...AND
ISOLATED NORTH OF CAPE BLANCO SUNDAY MORNING.

SO...A DRY FORECAST FOR THE WEEKEND ONCE THE TROUGH MOVES THROUGH...
WHICH SHOULD OCCUR BY NOON SATURDAY.  THE ONE EXCEPTION TO THIS WILL
BE THE AFOREMENTIONED MARINE STRATUS.

STOCKTON.
