AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
239 PM PST TUE FEB 8 2011

.SYNOPSIS...HIGH PRESSURE OVER THE REGION WILL MAINTAIN ABOVE NORMAL
DAYTIME TEMPERATURES AND COOL NIGHTS THROUGH FRIDAY. HIGH PRESSURE
WEAKENS OVER THE WEEKEND WITH A RETURN TO A WETTER PATTERN BY EARLY
NEXT WEEK.
&&

.DISCUSSION...HIGH PRESSURE OVER THE NE PAC COMBINED WITH A TROUGH
OF LOW PRESSURE ACROSS CA INTERIOR RESULTING IN TIGHT PRESSURE
GRADIENT AND BREEZY CONDITIONS ACROSS THE REGION THIS AFTERNOON.
EXPECT WINDS TO DECOUPLE AGAIN THIS EVENING WITH SLIGHT OFFSHORE
COMPONENT INHIBITING COASTAL STRATUS DEVELOPMENT. MOSTLY CLEAR SKIES
ACROSS CWA WILL ALLOW FOR VERY GOOD RADIATIONAL COOLING WITH WED
MORNING LOWS A DEGREE OR TWO COOLER THAN THIS MORNING. SIMILAR
CONDITIONS EXPECTED WED WITH DECREASED WINDS ALLOWING FOR SLIGHT
WARMING AT THE COAST. UPPER LOW BEGINS TO DEEPEN OVER THE GULF OF AK
THU WITH UPPER RIDGE WEAKENING IN RESPONSE. SFC WINDS WILL SHIFT TO
THE S BY FRI AS A COLD APPROACHES THE REGION. 12Z MODEL SOLNS KEEP
BULK OF PRECIP OFF TO THE N THROUGH THE WEEKEND SO TRENDED POPS DOWN
SLIGHTLY. MODEL SOLNS CONTINUE TO DIVERGE HEADING INTO NEXT
WEEK...BUT CONTINUE TO SHOW AN UPPER TROUGH OVER THE NE PAC.
GRADUALLY INCREASED POPS ABOVE CLIMO HEADING INTO THE MIDDLE OF NEXT
WEEK.
&&

.AVIATION...BRISK NORTH WIND AND UPSLOPE FLOW HAS GENERATED A FEW
PATCHES OF STRATOCU OVER THE NORTH COAST HILLS. HIGH BASED STRATOCU
SHOULD WANE WITH LOSS OF DAYTIME HEATING AND SETTLE INTO THE VALLEYS
THIS EVENING. A FEW PATCHES OF HIGH BASED STRATOCU MAY DRIFT OVER
COASTAL AIR TERMINALS THIS EVENING AS THE FLOW GOES NORTHEASTERLY
AND EVENTUALLY LIGHT EASTERLY. THEREFORE...UNDER OFFSHORE WIND FLOW
EXPECT VFR TO CONTINUE TO PREVAIL AT TAF SITES TONIGHT->WED. DJB
&&

.MARINE...MODERATELY STRONG NORTH WIND CONTINUED ACROSS THE WATERS
TODAY...THOUGH JUST A TAD LESS NEAR SHORE ALONG THE NORTH COAST
COMPARED TO YESTERDAY. GALE CONDITIONS WILL CONTINUE IN THE OUTER
WATERS TONIGHT AND SPILL INTO THE SOUTHERN INNER WATERS BRIEFLY WITH
GUSTS TO 40 KT. WINDS ACROSS THE INNER WATERS WILL DECREASE
ON WEDNESDAY AS A THERMAL TROUGH BUILDS ALONG THE COAST. MARGINAL
GALES LOOK TO CONTINUE ON WED FURTHER OFFSHORE HOWEVER (BEYOND
10NM). SEAS WILL STILL BE CHOPPY AND ROUGH INSIDE 10NM SO HAVE
CONTINUED WITH A SMALL CRAFT ADVISORY FOR THIS REASON. NAM12 AND
GFS WERE IN GOOD AGREEMENT ON SHOWING NORTHERLY GRADIENTS RELAXING
WED NIGHT INTO THU AS THE OFFSHORE RIDGE WEAKENS CONSIDERABLY. SEAS
WILL LAY DOWN THU->FRI AS A LONG PERIOD WESTERLY SWELL ENTERS THE
PICTURE AND DOMINATES THE SPECTRUM. OVERALL...WINDS LOOK TO REMAIN
ON THE LIGHT SIDE OVER THE WEEKEND AS A SERIES OF FRONT BUCK UP
AGAINST THE STRONG DOWN STREAM RIDGE. A STORM MAY BRING STRONG
SOUTH WIND MON OR TUE NEXT. DJB
&&

.EKA WATCHES/WARNINGS/ADVISORIES...
GALE WARNING UNTIL 10 PM PST THIS EVENING FOR PZZ455.
GALE WARNING UNTIL 10 PM PST WED FOR PZZ470-475.
