AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE EUREKA CA
850 AM PDT SAT APR 3 2010

.SYNOPSIS...SCATTERED SHOWERS WILL CONTINUE TODAY. A STRONG LATE
SEASON STORM MAY POTENTIALLY BRING SIGNIFICANT RAIN AND SNOWFALL
TO THE AREA SUNDAY MORNING THROUGH MONDAY MORNING.

&&

.UPDATE...QUICK UPDATE TO EXPIRE FROST ADVISORY. CLOUD COVER
SHOULD PREVENT WIDESPREAD FROST FROM FORMING...AND TEMPERATURES
CONTINUE TO WARM THIS MORNING.

&&

.PREV DISCUSSION... /ISSUED 836 AM PDT SAT APR 3 2010/

DISCUSSION...A LOT GOING ON THIS MORNING. TO START. REMNANT
SHOWERS FROM YESTERDAYS FRONT CONTINUE TO MOVE ACROSS THE AREA
THIS MORNING. THEY ARE DIMINISHING IN COVERAGE, BUT WOULDN'T BE
SURPRISED TO SEE THEM INCREASE IN COVERAGE A LITTLE AFTER SUNRISE
AS THE AIR DESTABILIZES. ALSO TEMPERATURES INLAND HAVE DROPPED
INTO THE MID 30S. THIS IS BECAUSE SHOWER ACTIVITY HAS DIMINISHED
IN THESE AREAS AND THERE ARE SOME BREAKS IN THE CLOUDS. THEREFORE,
ISSUED A FROST ADVISORY FOR THE NORTH COAST INTERIOR AND THE
MENDOCINO INTERIOR ZONES. TEMPERATURES SHOULD QUICKLY REBOUND
AFTER SUNRISE. NOW FOR THE BIGGER PROBLEM. A STRONG LATE SEASON
STORM MAY POTENTIALLY BRING SIGNIFICANT RAIN AND SNOWFALL TO THE
AREA SUNDAY MORNING THROUGH MONDAY MORNING. MODELS ARE IN FAIRLY
GOOD AGREEMENT SHOWING THE ENTIRE AREA RECEIVING AT LEAST ONE INCH
OF RAIN THROUGH MONDAY WITH THE RAIN FAVORED SPOTS SEEING UP TO 3
INCHES. THE BIG CONCERN IS THIS STORM HAS A LOT OF COLD AIR WITH
IT, MEANING SNOW LEVELS COULD DROP TO AROUND 3000 FT OR LOWER
DURING THE HEAVIEST PRECIPITATION ON SUNDAY. THIS WILL TRANSLATE
TO SEVERAL INCHES OF SNOW WITH SOME HIGHER LOCATIONS POSSIBLY
RECEIVING AROUND A FOOT. GIVEN THIS POTENTIAL FOR SIGNIFICANT SNOW
LATE IN THE SEASON AND THE INCREASED TRAVEL DUE TO THE HOLIDAY ON
SUNDAY, ISSUED A WINTER STORM WATCH FOR THE INTERIOR FROM SUNDAY
MORNING THROUGH MONDAY MORNING. INCREASED WINDS ALONG THE COAST,
HIGH SURF, AND THUNDERSTORMS WILL ALSO BE THREATS. SO STAY TUNED.
STROZ

AVIATION...SAT IMAGES SHOW A LARGE AREA OF COLD AIR CUMULUS ...SO
EXPECT SCATTERED SHOWER ACTIVITY TO AFFECT THE FORECAST AREA
THROUGH THE MORNING AND PERHAPS PAST NOON.

MARINE UPDATE...BUOYS #27 AND 14 ARE REPORTING SWELL HEIGHTS
BETWEEN 19 AND 22 FEET THIS MORNING. THE NW SWELL WILL PEAK LATE
THIS MORNING AND THEN SLOWLY SUBSIDE THROUGH THE NIGHT. ANOTHER
FRONTAL SYSTEM WILL CROSS THE WATERS ON SUNDAY...WITH SOUTH WINDS
EXPECTED TO REACH GALE FORCE OVER MUCH OF THE WATERS. SEAS ARE AGAIN
FORECAST TO RISE TO NEAR 18 FEET BY SWAN...AND FOR NOW WENT A FOOT
OR TWO BELOW THAT FOR MAX SWELL HEIGHT. TH/DB
