AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
943 PM PDT THU APR 22 2010

.SYNOPSIS...STRONG AND GUSTY WINDS WILL CONTINUE THIS EVENING AS
THE REGION REMAINS IN BETWEEN LOW AND HIGH PRESSURE SYSTEMS. DRY
AND QUIET WEATHER WILL THEN PREVAIL FOR FRIDAY AND THROUGH THE
WEEKEND AS AN UPPER LEVEL RIDGE BUILDS OVERHEAD. THE EXCEPTION
WILL BE ISOLATED SHOWERS ALONG THE OREGON BORDER EARLY SATURDAY
MORNING DUE TO A WEAK COLD FRONT.

&&

.UPDATE...NORTH WINDS HAVE DIMINISHED ACROSS COASTAL AREAS THIS
EVENING...WITH THE EXCEPTION BEING CAPE MENDOCINO WHERE GUSTS NEAR
60 MPH CONTINUE. SATELLITE IMAGES SHOW THE SOUTHERN CALIFORNIA LOW
CONTINUING TO PUSH SOUTH AND EAST AWAY FROM THE AREA...ALLOWING THE
SURFACE PRESSURE GRADIENT TO EASE. ALL AREAS EXCEPT FOR THE CAPE ARE
SHOWING GUSTS MUCH BELOW ADVISORY LEVEL AND THIS TREND WILL CONTINUE
AS THE LOW MOVES FURTHER INLAND. CMC

&&

.PREVIOUS DISCUSSION...MAIN FORECAST CONCERNS ARE WINDS AND
TEMPERATURES IN THE SHORT TERM. AFTERNOON SURFACE ANALYSIS CURRENTLY
DEPICTS PRESSURE GRADIENT OF APPROXIMATELY 9MB NW/SE ACROSS THE EKA
FORECAST AREA. UPPER FLOW PATTERN REMAINS NORTHERLY OVER THE REGION
WITH LARGE SLOW MOVING CLOSED LOW ROTATING OVER THE SOUTHWEST CONUS
AND POSITIVELY TILTED UPPER RIDGE AXIS BUILDING INTO THE PACIFIC
NORTHWEST. UNIFORM NORTHERLY FLOW REMAINS IN PLACE THROUGH
TODAY...WITH TIGHTENING GRADIENT IN BETWEEN THESE TWO SYSTEMS. WIND
ADVISORY WILL REMAIN IN EFFECT THROUGH THIS EVENING. A LOOK AT THE
CURRENT MESOWEST DATA SHOW THAT GUSTS AND WINDS SPEED ARE HIGHER
THAN YESTERDAY AT THIS TIME. GOOD MIXING WITH AMPLE SUNSHINE SHOULD
RESULT IN GUSTS CLIMBING TO NEAR 45 MPH ALONG THE COAST THIS
AFTERNOON/EARLY EVENING...ESPECIALLY WITH NAM SHOWING SUSTAINED
WINDS OF 40+ KT BELOW 950 MB. IMPACTS SHOULD BE SIMILAR TO YESTERDAY
AND INCLUDE DIFFICULTY DRIVING...AND SPORADIC POWER OUTAGES AND
MINOR TREE DAMAGE. WINDS SHOULD DIMINISH MORE QUICKLY THIS EVENING
THAN LAST EVENING AS LOW EJECTS INTO THE PLAINS...AND UPPER
RIDGE/RISING HEIGHTS BUILD OVERHEAD.

NEXT CONCERN IS FROST THREAT FOR TONIGHT...AND NEXT COUPLE NIGHTS AS
WELL.  WHILE WINDS WILL DIMINISH AND CLEAR SKIES WILL RESULT IN GOOD
DECOUPLING...BUILDING HEIGHTS ARE EXPECTED TO BRING IN A WARM
ENOUGH AIRMASS TO PREVENT WIDESPREAD FROST FROM DEVELOPING. PATCHY
FROST WILL CERTAINLY BE POSSIBLE IN FAVORED LOCATIONS
HOWEVER...ESPECIALLY NORTH. WILL MONITOR TEMPERATURES AND FROST
POTENTIAL THIS EVENING FOR POSSIBLE UPDATES. SIMILAR CONDITIONS
WILL OCCUR THROUGH THE WEEKEND...WITH THE GREATEST THREAT OF FROST
REMAINING FARTHER NORTH.

FORECAST ATTENTION THEN TURNS TO YET ANOTHER LATE SEASON STORM
SYSTEM TO AFFECT THE AREA MONDAY NIGHT THROUGH WEDNESDAY. 12Z GFS
HAS SPED UP ABOUT 6 HOURS WITH THE ONSET OF HEAVIEST PRECIP...BUT
WILL MAINTAIN TIMING IN GRIDS PER CONSISTENCY IN GEM AND ECMWF
MODELS.  STRONG DYNAMICS EXIST ONCE AGAIN WITH THIS NEGATIVELY TILTED
TROUGH AS IT DEEPENS ALONG THE WEST COAST. THIS SYSTEM LOOKS TO
BRING ANOTHER WIDESPREAD 1 TO 2 INCHES TO THE EKA FORECAST AREA.
SNOW LEVELS WILL DROP TO AROUND 3500 FT TUESDAY AFTER THE BULK OF
THE PRECIP HAS FALLEN. SOME OF THE HIGHER PASSES MAY SEE SOME SNOW
ACCUMULATION. MODELS SHOWING COLD AIRMASS AND UNSETTLED/SHOWERY
PATTERN CONTINUING THROUGH THE REMAINDER OF THE WEEK AS LONG WAVE
TROUGH PATTERN SITS ACROSS THE WEST. HENRY

&&

.AVIATION...ANOTHER DAY OF STRONG NORTHERLY WINDS HAS CONTINUED OVER
NORTHWEST CALIFORNIA AS A TIGHT PRESSURE GRADIENT PREVAILS OVER THE
REGION. HOWEVER...THIS EVENING THE PRESSURE GRADIENT WILL START TO
RELAX AND WINDS WILL BEGIN TO TAPER AS HIGH PRESSURE BUILDS TOWARD
THE NORTH COAST...AND LOW PRESSURE WEAKENS INLAND. SKY AND
VISIBILITY WILL REMAIN VFR. WITH SOME AREAS OF VERY LIGHT
WINDS...POCKETS OF FOG ARE REMOTELY POSSIBLE OVER A FEW LOCATIONS IN
THE EARLY MORNING BUT NOTHING EVEN CLOSE TO WIDESPREAD. SO...FG/BR
ISSUE WILL NOT BE ADDRESSED IN THE TAFS. ASHFORD

&&

.MARINE...THE FORECAST REMAINS ON TRACK AND DID NOT MAKE ANY MAJOR
CHANGES. GALE FORCE WINDS AND HAZARDOUS SEAS WILL CONTINUE AS THE
EASTERN PACIFIC HIGH INTERACTS WITH LOW PRESSURE INLAND. THE BUOY
