WERE BLUSTERY ALONG THE COAST AND ALONG THE RIDGETOPS. WINDS GUSTED
UP TO 25 MPH ALONG THE COAST AND UP TO 50 MPH OVER THE NORTH COAST
INTERIOR RIDGES. A BRIEF LULL IN THE WINDY CONDITIONS ARE EXPECTED
THIS EVENING...BUT AS THE NEXT SYSTEM APPROACHES WINDY CONDITIONS
WILL BE UPON US ONCE AGAIN OVERNIGHT.

THE ACTIVE WEATHER PATTERN CONTINUES OVERNIGHT INTO FRIDAY WITH
ANOTHER SURFACE COLD FRONT EXPECTED TO PUSH INTO NORTHERN
CALIFORNIA. SATELLITE IMAGERY SHOWED THE MAIN SURFACE LOW CENTERED
NEAR 49N AND 149W AT 22Z (3 PM PDT). IT WILL CONTINUE TO MOVE
NORTHEAST TOWARD WASHINGTON AND NORTHERN OREGON THROUGH FRIDAY. THE

OF THE COLD FRONT WITH SPEEDS OF 15 TO 30 MPH ALONG THE NORTH COAST
WITH GUSTS UP TO 45 MPH OVER THE INTERIOR MOUNTAIN TOPS. AMSU

RANGE FROM 1 TO 2 INCHES ACROSS NW CA...WITH LOCAL AMOUNTS TO BE
HIGHER IN THE OROGRAPHICALLY FAVORED REGIONS OF THE COASTAL RANGE.

SHOWERS WILL CONTINUE BEHIND THE FRONT FRIDAY AFTERNOON. AS COLDER
AIR ALOFT BRUSHES THE NORTHERN PART THE CWA...IT WILL BRING A
POSSIBILITY OF CONVECTION...MAINLY TO THE NORTHERN COASTAL WATERS.
THEREFORE HAVE INCLUDED THE MENTIONED OF A SLIGHT CHANCE FOR
THUNDERSTORMS FRIDAY EVENING AS LI VALUES WILL RANGE FROM 0 TO MINUS
1 OVER THE AREA OF CONCERN. CURRENT SNOW LEVELS IN THIS WARM SECTOR
OF THE STORM ARE NEAR 7000 FEET. SNOW LEVELS WILL LOWER BY FRIDAY
EVENING TO NEAR 4500 FEET AS COLDER AIR FILTERS INTO THE REGION. SO
LIGHT SNOW SHOWERS ARE POSSIBLE ABOVE 4500 FEET FRIDAY NIGHT INTO
EARLY SATURDAY MORNING.

AS A RIDGE BUILDS IN FROM THE WEST SATURDAY AFTERNOON...IT WILL
BEGIN A SHORT LIVED DRY PATTERN THROUGH EARLY NEXT WEEK. EXPECT LOW
TEMPS TO DIP INTO THE 30S INLAND AND THE MID TO LOWER 40S ALONG THE
COAST WITH SOME PATCHY RADIATIONAL FOG IN THE VALLEYS SUNDAY AND
MONDAY NIGHT. DAYTIME TEMPS SHOULD INCREASE TO MORE PLEASANT
READINGS IN THE MID 60S ALONG THE COAST AND MID TO UPPER 70S INLAND
