AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
230 PM PDT THU APR 2 2009

.SYNOPSIS...A WEAK SYSTEM WILL JUST GRAZE THE REGION OVERNIGHT
PERHAPS BRINGING A LIGHT SHOWER TO NORTHERN PORTIONS OF THE
REGION...OTHERWISE DRY WEATHER CAN BE EXPECTED LATER TONIGHT
THROUGH SATURDAY AS HIGH PRESSURE BUILDS ACROSS THE AREA. THIS WILL
BRING UNSEASONABLY COLD MORNINGS TO THE REGION...WITH THE THREAT OF
FROST FOR INTERIOR AREAS TONIGHT AND NEAR FREEZING CONDITIONS FOR
COASTAL AND INTERIOR AREAS TOMORROW NIGHT. WINDY CONDITIONS CAN BE
EXPECTED FRIDAY AFTERNOON.

&&

.DISCUSSION...WINDS HAVE BEEN INCREASING THIS AFTERNOON BEHIND A
COLD FRONT WHILE ANOTHER WEAK UPPER LEVEL DISTURBANCE DIVES TOWARD
THE REGION FROM THE GULF OF ALASKA. THIS DISTURBANCE MAY YET PRODUCE
A FEW SHOWERS THIS EVENING...SO WILL LEAVE SOME MENTION OF POPS IN
THE FORECAST FOR TONIGHT. HOWEVER...MOST AREAS WILL SEE A DOWNWARD
TREND IN PRECIPITATION WITH ANY SHOWERS REMAINING ON THE LIGHT SIDE.
WINDS WILL LIKELY REMAIN GUSTY THROUGH AT LEAST MIDNIGHT...BUT WILL
EASE DURING THE PREDAWN HOURS. WE WILL LEAVE THE FROST ADVISORY IN
PLACE FOR TONIGHT FOR THE INTERIOR ZONES...BUT THE BETTER CHANCE FOR
FROST AND/OR FREEZING CONDITIONS WILL OCCUR TOMORROW NIGHT WITH
WEAKER WINDS AND DRIER AIR.

DRY WEATHER SHOULD CONTINUE UNTIL AT LEAST SATURDAY NIGHT AND QUITE
POSSIBLY LONGER...AS ALL MEDIUM RANGE SOLUTIONS ARE CONSISTENT WITH
CLOSING OFF A LOW WELL OFFSHORE. THIS SYSTEM WILL NOT BE A TYPICAL
FAST MOVING FRONT WITH DISCRETE START/END TIMES FOR PRECIPITATION
BUT RATHER A MEANDERING SYSTEM WHICH WILL OFFER PERIODIC PROSPECTS
FOR RAIN WHERE TIMING AND DURATION ARE DIFFICULT TO PIN DOWN.
HOWEVER THE THREAT FOR RAINS AND HIGHER ELEVATION SNOWS IS FAIRLY
HIGH FOR THE EARLY PORTION OF NEXT WEEK. BURGER

&&

.AVIATION...DRIER BRISK NORTHERLY FLOW WILL PROVIDE MAINLY VFR
CONDITIONS TO ALL AREAS FOR THE NEXT TAF CYCLE.  GUSTY WINDS TO NEAR
25 TO 30 KTS CAN BE EXPECTED AT KCEC AND KACV DURING THE NEXT 24
HOURS ...EXCEPT FOR A BRIEF PERIOD OF DIMINISHED WINDS DURING THE
LATE NIGHT AND EARLY MORNING HOURS.

&&

.MARINE...HIGH PRESSURE BOTH AT THE SURFACE AND ALOFT IS BUILDING
RAPIDLY BEHIND THIS MORNINGS WEAK FRONT.  NORTH WIND WILL CONTINUE TO
RAMP UP OVER THE COASTAL WATERS THIS AFTERNOON AND TONIGHT PEAKING
TOMORROW.  THE STRONG NORTH WINDS HAVE WARRANTED A GALE WARNING OVER
ALL AREAS EXCEPT FOR THE NEAR COAST ZONE NORTH OF CAPE MENDOCINO.
THIS AREA HOWEVER WILL STILL SEE HARD SMALL CRAFT CONDITIONS THROUGH
THE NEXT 36 HOURS. THE CURRENT NORTHWEST SWELL WILL COMBINE WITH
BUILDING WIND SEA BRINGING HAZARDOUS WARNING CONDITIONS TO ALL
WATERS THROUGH THE FRIDAY NIGHT.  PRESSURE GRADIENTS WEAKEN
CONSIDERABLY EARLY SATURDAY AS AN APPROACHING LOW PRESSURE SYSTEM
BEGINS TO AFFECT THE REGION.

&&
