CA. COASTSIDE THE NORTHERLY WINDS WHICH HAVE BEEN A BIT GUSTY
EVERY AFTERNOON SHOULD BE LIGHTER TODAY. THUS A NICE AFTERNOON IS
ON TAP WITH PERHAPS SOME HIGH CLOUDS PASSING OVERHEAD. ACROSS THE
INTERIOR AIRMASS WARMING SHOULD LEAD TO A RELATIVELY WARM
AFTERNOON OVER THE VALLEYS. OVERALL A COLD CORE TROUGH, AS SEEN
ON WATER VAPOR IMAGERY, CONTINUES TO SHIFT EASTWARD OVER THE GREAT
BASIN WHILE A RIDGE OFFSHORE SLOWLY NOSES TOWARDS THE PACIFIC
NORTHWEST. RIDGING WILL MAKE FRIDAY A PRETTY NICE DAY AS WELL WITH
SLIGHTLY WARMER TEMPERATURES AND AGAIN MOSTLY CLEAR SKIES. THIS
WILL BE SHORT LIVED THOUGH AS ANOTHER PACIFIC STORM SYSTEM
APPROACHES THE WEST COAST BRINGING RAIN TO NORTHERN CALIFORNIA
STARTING SATURDAY EVENING. THE MODELS SEEM TO BE IN PRETTY GOOD
AGREEMENT WITH THE TIMING OF THE FIRST SPOKE OF VORTICITY AND RAIN
TOTALS SO POPS WERE INCREASED ON SATURDAY. SCATTERED SHOWERS WILL
FOLLOW ON SUNDAY AND SUNDAY NIGHT WHILE SNOW LEVELS WILL REMAIN
HIGH ENOUGH WHERE IMPACTS WILL BE NEGLIGIBLE.

AS WEAK HIGH PRESSURE HOLDS OVER THE REGION. SIGNIFICANT WAVE
HEIGHTS WILL SLOWLY BUILD THIS WEEKEND AS A STORM SYSTEM APPROACHES
THE WEST COAST. THE SWELL FORERUNNERS FROM THIS STORM WILL ARRIVE ON

SUN OR SUN NIGHT FOR SIGNIFICANT WAVE HEIGHTS TO REACH OR EXCEED 10
FT. THE STORM HAS BEEN BREWING OVER THE ALEUTIAN ISLAND CHAIN FOR
THE LAST TWO DAYS...SO CONFIDENCE IS HIGH THE ENP IS ON TARGET WITH
TIMING OF THE SWELL. SIGNIFICANT WAVE HEIGHTS ARE STILL A BIT
UNCERTAIN FOR SUN AND FADE EVEN MORE ON MONDAY DUE TO THE HIGHLY
VARIABLE AND LARGE SPREAD IN THE GFS SURFACE WIND FIELDS.
