AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
300 PM PDT THU APR 15 2010

.SYNOPSIS...AN UPPER LEVEL LOW WILL MOVE INTO THE REGION LATE FRIDAY
AND SLOWLY MOVE ACROSS THE REGION BEFORE MOVING INLAND THE MIDDLE OF
NEXT WEEK. THIS WILL MAINTAIN A CHANCE OF PRECIPITATION THROUGH
EARLY NEXT WEEK.
&&

.UPDATE...WEAK HIGH PRESSURE AND A PACIFIC STORM OFFSHORE WILL
COMBINE TO PROMOTE MAINLY CLEAR SKIES AND ANOTHER COOL NIGHT
ACROSS NORTHWEST CALIFORNIA.  SOME HIGH CLOUDS ASSOCIATED WITH THE
STORM OFFSHORE MAY BE PRESENT ON FRIDAY HOWEVER LITTLE TO NO
PRECIPITATION IS EXPECTED.

&&

.DISCUSSION...CLEAR SKIES AND A RESIDUAL COLD AIRMASS BROUGHT THIS
MORNINGS TEMPERATURES DOWN TO THE LOW 30S ACROSS THE INTERIOR ZONES
WARRANTING THE ISSUANCE OF A FROST ADVISORY.  HEIGHTS AND THICKNESS
VALUES ARE SLIGHTLY RISING TODAY.  THIS COMBINED WITH AN EXPECTED
INCREASE OF HIGH CLOUDS OVERNIGHT SHOULD HELP PREVENT MORNING TEMPS
FROM PLUMMETING AGAIN.  ALTHOUGH THERE WILL BE SOME LOCALIZED AREAS
OF COLD TEMPERATURES DO NOT ANICIPATE WIDESPREAD SUB 36 DEGREE TEMPS
ACROSS THE REGION. FORECAST MODELS IN GOOD AGREEMENT ON DRAGGING THE
LATEST STORM OFF TO THE NORTH AND JUST BY-PASSING THE CWA...THEN
RETROGRADING THE FEATURE BACK OFF THE TO THE WEST. A MINOR SHORT
WAVE EJECTS OUT OF THE BASE OF THE TROUGH AND THEN MOVES ACROSS NW
CA EARLY FRI...BUT A LACK OF MOISTURE SHOULD INHIBIT ANY SIGNIFICANT
RAINFALL...OR AT MOST VERY LITTLE RAINFALL WITH THE MAIN FOCUS OF
ANY SHOWER DEVELOPMENT OVER THE HIGHER TERRAIN AND ORCA BORDER. POPS
INCREASE SUBSTANTIALLY EARLY NEXT WEEK AS THE LONG WAVE TROUGH OVER
THE NE PAC SLOWLY MOVES TOWARDS THE COAST. PRECIP CHANCES WILL
PERSIST THROUGH MID WEEK BEFORE THE TROUGH AXIS MOVES FAR ENOUGH E.
MODELS REMAIN IN FAIR AGREEMENT ON A WARMER AND DRIER PATTERN FOR
THE LATTER HALF OF NEXT WEEK AS AN UPPER LOW CUTS OFF OVER THE SW
U.S. AND AN UPPER LEVEL RIDGE BUILDS OVER THE PAC NW.

.AVIATION...VFR CONDITIONS AND LIGHT WINDS WILL PREVAIL. A LOW WELL
OFFSHORE OF CALIFORNIA WILL SPREAD HIGH CLOUDS ACROSS NW CA LATE
TONIGHT. TH

.MARINE...A MIXED SEA STATE COMPRISED OF THREE DISTINCT SWELL TRAINS
WILL IMPACT THE WATERS THROUGH THE WEEKEND...A LONG PERIOD SMALL S
SWELL...A MEDIUM PERIOD SMALL W SWELL...AND A SHORT PERIOD LARGER SW
SWELL. A COLD FRONT WILL MOVE ACROSS THE WATERS EARLY NEXT WEEK
FOLLOWED BY STRONG NORTH WINDS AND LARGE CHOPPY SEAS. TH
