AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
241 PM PST MON NOV 30 2015

.SYNOPSIS...AN ACTIVE WEATHER PATTERN WILL BRING PERIODS OF RAIN
TO THE REGION THIS WEEK WITH THE BEST CHANCES FOR RAIN IN HUMBOLDT
AND DEL NORTE COUNTIES. A STRONG STORM SYSTEM MAY BRING GUSTY
WINDS TO NORTHWEST CALIFORNIA MID TO LATE WEEK. TEMPERATURES WILL
BE SEVERAL DEGREES WARMER THIS WEEK AS COMPARED TO THIS PAST
WEEKEND.

&&

.DISCUSSION...LIGHT SHOWERS WILL LINGER INTO THE EARLY EVENING HOURS
AS A WEAK SYSTEM MOVES INLAND. A SHORTWAVE RIDGE WILL RAPIDLY MOVE
OVER NORTHWEST CALIFORNIA TONIGHT THROUGH TUESDAY BRINGING WARMING
TEMPERATURES...RISING SNOW LEVELS...AND SOME CLEARER SKIES.
TEMPERATURES TONIGHT WILL BE SEVERAL DEGREES WARMER THAN LAST
NIGHT AND TUESDAY AFTERNOON HIGHS WILL BE 5 TO 10 DEGREES WARMER
THAN MONDAY AS 850 MB TEMPERATURES WARM 3 TO 4 DEGREES OVER THE
NEXT 24 HOURS.

AN ACTIVE WEATHER PATTERN IS IN STORE FOR THE REMAINDER OF THE WEEK
WITH THE NEXT FRONTAL SYSTEM APPROACHING THE DEL NORTE AND HUMBOLDT
COASTS LATE TUESDAY AFTERNOON/EVENING. THOUGH THERE WILL BE CHANCES
FOR RAIN SOUTH AND EAST OF HUMBOLDT COUNTY...THE MAJORITY OF THE
RAIN WILL BE TARGETED IN NORTHERN HUMBOLDT AND DEL NORTE COUNTIES
THOUGH WEDNESDAY AS A SERIES OF SYSTEMS SLIDE NORTH ON THE EAST SIDE
OF A DEEP TROUGH OVER THE GULF OF ALASKA. THERE ARE SOME MODEL
POSITIONING AND TIMING DIFFERENCES WITH THESE SYSTEMS RESULTING IN
LOWER THAN NORMAL CONFIDENCE IN PRECIPITATION AMOUNTS...BUT HIGHER
THAN NORMAL CONFIDENCE IN A WET FORECAST.

THE MOST SIGNIFICANT DIFFERENCE BETWEEN THE GFS AND ECMWF EXISTS ON
THURSDAY AS THE TROUGH TAKES ON A NEGATIVE TILT AND PROGRESSES INTO
THE WEST COAST. THE GFS AND NAM BOTH DEVELOP A STRONG SURFACE LOW IN
ADVANCE OF THE TROUGH AND MOVE IT NORTHEAST AROUND 60 NAUTICAL
MILES OFF THE COAST. A DEEPENING LOW LIKE THIS OFTEN RESULTS IN
ROBUST SOUTHERLY FLOW OUT AHEAD OF THE SYSTEM...ALLOWING FOR A
PERIOD OF DRY BUT CLOUDY CONDITIONS. AND JUST AS EXPECTED...THE
GFS AND NAM BOTH INDICATE DRY CONDITIONS FOR THE ENTIRE AREA
BEGINNING WEDNESDAY EVENING THROUGH THURSDAY MORNING BEFORE A
STRONG FRONT IMPACTS THE COAST. ADDITIONALLY...THE GFS AND NAM
WOULD SUGGEST A PERIOD OF STRONG GUSTY SOUTH WINDS IN ADVANCE OF
THE FRONTAL PASSAGE. THIS SOLUTION COULD RESULT IN A DECENT WIND
EVENT AND POTENTIALLY A CONVECTIVE LINE OF HEAVY SHOWERS MOVING
THROUGH THE REGION. HOWEVER...THE ECMWF IS MUCH WEAKER...DOES NOT
DEVELOP THE STRONG SURFACE LOW OFF THE NORTHWEST CALIFORNIA
COAST...AND RESULTS IN A FASTER FRONTAL PASSAGE WITH LIGHTER WINDS
AND LESS OF A BREAK IN THE WET CONDITIONS THROUGH THURSDAY. THE
SYSTEM STILL THREE DAYS OUT SO THERE IS PLENTY OF TIME FOR THE
MODELS TO COME INTO AGREEMENT...BUT AS FOR NOW WILL STICK WITH
SOME MODERATELY STRONG GUSTY WINDS ACROSS THE AREA AND THE BEST
CHANCES FOR RAIN ON THURSDAY.

MODEL DIFFERENCES ON THURSDAY RESULT IN TIMING DIFFERENCES FRIDAY
INTO NEXT WEEKEND...BUT THE GENERAL CONSENSUS IS THAT AN ACTIVE
PATTERN WILL CONTINUE. A 12-24 HOUR PERIOD OF DRY CONDITIONS WILL
LIKELY DEVELOP BEHIND THE DEPARTING TROUGH FOLLOWED BY A RETURN TO
MOIST WESTERLY FLOW AND RAIN CHANCES DURING THE WEEKEND INTO NEXT
WEEK. RPA

&&

.AVIATION...VFR TO MVFR CONDITIONS AND LIGHT WINDS WILL CONTINUE
AT KCEC, KACV, AND KUKI THROUGH TONIGHT WITH MOSTLY CLOUDY SKIES
OCCURRING. THE LOWER CONDITIONS WILL BE DUE TO TEMPORARILY REDUCED
CEILINGS AND/OR VISIBILITIES AS A FEW SHOWERS MOVE THROUGH THE AREA
ASSOCIATED WITH A DISSIPATING COLD FRONT. VFR CONDITIONS AND DRIER
CONDITIONS WILL PREVAIL AT KCEC, KACV, AND KUKI ON TUESDAY.

&&

.MARINE...WINDS AND SEAS WILL DIMINISH THE NEXT FEW DAYS IN THE
WAKE OF A WEAK DISSIPATED COLD FRONT. HOWEVER SMALL CRAFT ADVISORIES
WILL CONTINUE ACROSS THE OUTER WATERS THROUGH TUESDAY NIGHT AND WILL
LIKELY BE EXTENDED ACROSS THE NORTHERN OUTER WATERS. SMALL CRAFT
ADVISORIES WILL CONTINUE ACROSS THE NEAR SHORE WATERS THROUGH EARLY
TUESDAY MORNING. A STRONGER COLD FRONT WILL MOVE NEAR THE WATERS
THURSDAY INCREASING THE WINDS AND STEEP SEAS. GALE CONDITIONS ARE
LIKELY ACROSS THE OUTER WATERS THURSDAY AS A LOW PRESSURE SYSTEM
TRACKS NORTH OF THE WATERS.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...NONE.
NORTHWEST CALIFORNIA COASTAL WATERS...
     SMALL CRAFT ADVISORY UNTIL 3 AM PST TUESDAY FOR PZZ450-455.

     SMALL CRAFT ADVISORY UNTIL 2 AM PST WEDNESDAY FOR PZZ470-475.
