AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
440 AM PST SUN FEB 15 2009

.SYNOPSIS...LOW PRESSURE OFF THE NORTH COAST WILL PRODUCE PERIODS OF
RAIN AND HIGH ELEVATION SNOW THROUGH MONDAY. A BREAK IN THE WET
PATTERN IS EXPECTED FOR THE MIDDLE OF THE WEEK BEFORE THE THREAT FOR
RAIN AND SNOW RETURNS.

&&

.SHORT TERM...TODAY THROUGH TUESDAY...QUITE THE COMPLICATED FORECAST
PACKAGE WITH IMMEDIATE CONCERNS BEING WIND...CONVECTION...PRECIP
AMOUNTS...AND SNOW LEVELS. SURFACE AND UPPER LEVEL LOWS ARE LOCATED
SOME 350 NM SW OF EUREKA AT EARLY MORNING...OR A LITTLE SOUTH OF
MODEL SUITE INITIALIZATION. HEAVY PRECIPITATION OVERNIGHT IN
ASSOCIATION WITH THE OCCLUDED FRONT HAS SHIFTED NORTH AND EAST OF
THE AREA...WITH A DRY SLOT IMPINGING ON THE COAST. A NUMBER OF
LIGHTNING STRIKES WERE RECORDED NEAR POINT ARENA...BOTH OVER THE
WATER AND ON THE LAND...EARLIER THIS MORNING RIGHT ALONG THE FRONT.
WINDS HAVE ALSO BEEN A BIG STORY ALONG THE RIDGES AND ALSO THE
MENDOCINO COAST WITH GUSTS OF 50 MPH OR GREATER.

FOR TODAY...PERIODS OF SHOWERS WILL CONTINUE AS THE LOW WOBBLES
OFFSHORE. THERE REMAINS SOME THREAT FOR THUNDER...PRIMARILY ACROSS
THE SOUTHERN WATERS...OTHERWISE WINDS WILL SLOWLY EASE. WE HAVE LEFT
THE WINTER STORM WARNING UP DESPITE THE DECREASE IN PRECIP AT THE
CURRENT TIME...AS A RATHER POTENT SHORTWAVE ROUNDING THE BASE OF THE
TROUGH WILL REGENERATE MORE SHOWERS...AND HIGHER ELEVATION
SNOWS...LATER TODAY.

INTERMITTENT SHOWERS WILL CONTINUE INTO MONDAY AS THE LOW SLOWLY
APPROACHES THE COAST. WE HAVE MAINTAINED THUNDERSTORM CHANCES FOR
THE WATERS AND INTO COASTAL MENDOCINO FOR TOMORROW AS CONVECTIVE
PARAMETERS LOOK REASONABLE. THE LOW FINALLY IS ABSORBED AND SHUNTED
EAST BY TUESDAY SO A DRYING A WARMING TREND WILL COMMENCE.
BURGER

.LONG TERM...TUESDAY NIGHT THROUGH SATURDAY...VERY LITTLE CHANGE
FROM THE PREVIOUS FORECAST. THE WET PATTERN WE'VE BECOME ACCUSTOMED
TO IN FEBRUARY WILL TAKE A BRIEF HIATUS THROUGH THE MIDDLE OF THE
WEEK WITH THE NEXT SYSTEM PARKED WELL OFFSHORE. LOW LEVEL OFFSHORE
FLOW MAY YIELD SOME PLEASANT AFTERNOON WEATHER IF CLOUDS REMAIN
TRANSPARENT ENOUGH. CONSIDERABLE UNCERTAINTY REMAINS WITH RESPECT TO
THE RETURN OF WET WEATHER AS THE PATTERN UPSTAIRS BECOMES SOMEWHAT
JAMMED. SO FOR NOW HAVE CONTINUED THE TREND OF GRADUALLY INCREASING
PRECIP CHANCES TOWARDS THE WEEKEND. BURGER

&&

.AVIATION...A SFC LOW OFF THE COAST IS BRINGING RA AND HIGHER
ELEVATION SN THIS MORNING. SAT IMAGERY SHOWS A DRY SLOT MOVG INTO
CWA FROM SW ATTM WITH CU BEGINNING TO DEVELOP IN IT. WILL TRANSITION
PRECIP FROM STRATIFORM TO SHOWERY EARLY THIS AM AS LOW WILL SLOWLY
DRIFT S. IN ADDITION TO PRECIP AND MVFR CIGS...THE PRESSURE GRADIENT
REMAINS STRONG ACROSS THE CWA WITH A 9.4MB DIFF BETWEEN SAC AND ACV
AND 10.8MB BETWEEN SAC/CEC. THIS WILL MAINTAIN GUSTY...BREEZY WINDS
ESPECIALLY ALONG THE COAST AND HIGHER TERRAIN. WRF AND RUC MODELS IN
DECENT AGREEMENT NEXT SHOT OF SHOWERS REACHING THE COAST LATE THIS
MORNING TO EARLY AFTERNOON AS ANOTHER VORT MAX ROTATES AROUND THE
UPPER LOW SO INCLUDED TEMPO MVFR CONDITIONS THROUGH THE AFTERNOON. BC

&&

.MARINE...S TO SE GALES WILL CONTINUE THROUGH THE MORNING AS THE
COLD FRONT FORM A SURFACE LOW AROUND 40N129W PUSHES ACROSS THE
WATERS. OFFSHORE BUOYS HAVE REPORTED GUSTS TO 45-47KTS AHEAD OF THE
FRONT...SO INCLUDED MENTION OF OCCASIONAL GUSTS TO STORM FORCE OVER
THE SOUTHERN WATERS THIS MORNING. MODELS IN GOOD AGREEMENT IN SFC
LOW WEAKENING AS IT REMAINS NEARLY STATIONARY TODAY...THEN DRIFT S
MON. ANOTHER SURFACE LOW WILL DROP OUT OF THE GULF OF AK AND MOVE S
JUST OFF THE CA COAST BY MID WEEK. GIVEN THE UNSETTLED WEATHER
PATTERN...GALE AND HAZ SEAS WARNINGS WILL BE POSSIBLE AGAIN BY MID
WEEK. BC
