POSSIBLE IN THE NORTHERN INLAND VALLEYS IN THE MORNING.

.LONG TERM...
BY EARLY FRIDAY THE GFS OPERATIONAL MODEL IS WANTING TO BRING IN A
500MB TROUGH THOUGH THE ENSEMBLE MEAN...THE ECMWF AND THE CANADIAN
ARE 12 TO 24 HOURS SLOWER. DUE TO THE STRONG OMEGA BLOCKING WE
TENDED TOWARD THE SLOWER SOLUTION ALTHOUGH KEPT CHANCE POPS
THROUGH THE TIME FRAME DUE TO LOW CONFIDENCE ON THE TIMING. BY LATE
SATURDAY INTO SUNDAY MODELS ARE GOOD AGREEMENT THAT THE FLOW WILL
BECOME MORE ZONAL. SO WE RAISED POPS IN THAT TIME PERIOD
ESPECIALLY IN THE NORTH. MKK

.MARINE...LIGHT TO MODERATE SOUTHERLY WINDS WILL CONTINUE TONIGHT
