AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
309 AM PST THU MAR 4 2010

.SYNOPSIS...HIGH PRESSURE WILL BRING DRY WEATHER TO NORTHWEST
CALIFORNIA TODAY. A STORM WILL BRUSH PAST THE REGION LATE TONIGHT
INTO FRIDAY...BRINGING RAIN AND HIGH ELEVATION SNOW.

&&

.DISCUSSION...AFTER A CHILLY AND NEARLY CLEAR START TO THE MORNING
TEMPERATURES WILL WARM UP BY THIS AFTERNOON, ALLOWING ANY MORNING
FROST AND FOG TO BURN OFF. A WEAK RIDGE OF HIGH PRESSURE MOVING
OVER THE WEST COAST WILL BRING THE AREA DRY WEATHER TODAY. THIS
RIDGE WILL QUICKLY MOVE TO THE EAST THIS EVENING AND WEAKEN.
REPLACING IT JUST AS QUICKLY WILL BE A TROUGH OF LOW PRESSURE. THE
MODELS CONTINUE TO AGREE THAT A STORM WILL DROP DOWN FROM THE
NORTH LATE TONIGHT AND BRUSH ALONG OUR COAST INTO FRIDAY. THE MAIN
AREA OF LOW PRESSURE SHOULD STAY JUST OFF OF OUR COAST. SO POPS
AND QPF WILL BE THE HIGHEST ALONG THE COAST AND DECREASE INLAND.
THIS STORM DOES HAVE A DECENT AMOUNT OF COLD AIR WITH IT, THOUGH
IT'S NOT AS COLD AS THE LAST ONE. QPF AMOUNTS WILL ALSO BE LOWER,
TOTALING ABOUT HALF AN INCH ACROSS THE AREA, WHICH IS ABOUT HALF
OF THE AMOUNTS FROM THE LAST STORM. SO COLD AIR WITH THIS STORM
COMBINED WITH THE COLD AIR ALREADY IN PLACE WILL ALLOW SNOW LEVELS
DROP TO NEAR 3000 FT BY LATE FRIDAY. SNOW AMOUNTS MAY TOTAL A FEW
INCHES, BUT AS OF NOW THE FORECAST KEEPS THEM JUST UNDER ADVISORY
CRITERIA. SATURDAY LOOKS DRY, BUT SUNDAY WILL BE THREATENED BY
MORE PRECIPITATION. STROZ

&&

.AVIATION...AN UPPER RIDGE OVER THE AREA TODAY WILL PRODUCE
GENERALLY VFR ACROSS THE AREA. INLAND AREAS WILL SEE PATCHY IFR
CONDITIONS BUT THIS IS EXPECTED TO DISSIPATE BY EARLY AFTERNOON.
ANOTHER FRONTAL SYSTEM WILL APPROACH TONIGHT AND BRING RAIN AND
MVFR CIGS BY EARLY FRI. DJB

&&

.MARINE...A WEST SWELL WILL SLOWLY SUBSIDE TODAY. ANOTHER LOW
PRESSURE SYSTEM WILL APPROACH THE COAST ON FRIDAY. SOUTHERLY WINDS
WILL INCREASE AHEAD OF THE SURFACE FRONT BUT SHOULD REMAIN JUST
UNDER ADVISORY LEVEL. THE NORTHERLY WIND SURGE LOOKS MORE
INTERESTING...WITH THE NAM12 BEING THE MOST AGGRESSIVE. MODELS
KEEP FLIP FLOPPING AROUND ON THE MAGNITUDE AND GALE CHANCES LOOK
MINIMAL. ANOTHER LONG PERIOD SWELL WILL MOVE INTO THE WATERS FROM
THE NW ON FRIDAY...BUILDING TO NEAR 14 FT AT 15 SECONDS BY FRIDAY
AFTERNOON/EVENING. ANOTHER NW SWELL WILL MOVE INTO THE WATERS ON
SUNDAY...AND WAVE HEIGHTS WILL LIKELY REMAIN ABOVE 10 FEET THROUGH
THE WEEKEND. DJB

&&

.EKA WATCHES/WARNINGS/ADVISORIES...

CA...NONE.
