Area forecast discussion, Jan 13, 3:26 AM PST, 6 hours 1 minute before
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
326 AM PST WED JAN 13 2016
.SYNOPSIS...POST FRONTAL SHOWER ACTIVITY WILL BE OBSERVED ACROSS
THE REGION TODAY. ANOTHER PACIFIC FRONT WILL BRING RAIN AND HIGH
ELEVATION SNOW ON THURSDAY AND THURSDAY NIGHT. THE INCLEMENT
WEATHER PATTERN WILL CONTINUE THROUGH THE REMAINDER OF THE WEEK AS
A SERIES OF PACIFIC STORMS IMPACT THE WEST.
&&
.DISCUSSION...ALTHOUGH THE FRONT HAS MOVED WELL EAST OF THE AREA
THE UPPER TROUGH IS LAGGING BEHIND AND WILL CONTRIBUTE
INSTABILITY SHOWERS TO MUCH OF THE CWA THROUGHOUT THE FIRST HALF
OF THE DAY AT LEAST. LEFT TSTORM CHANCES IN THE FORECAST AS WELL
ALTHOUGH NONE OF BEEN OBSERVED YET. ALTHOUGH WITH A LITTLE HEATING
LATER IN THE DAY THE POTENTIAL STILL EXISTS. LATER THIS EVENING
SHOWERS WILL TAPER OFF SIGNIFICANTLY AS A VERY BRIEF SHORTWAVE
RIDGE BUILDS IN. THURSDAY THE NEXT SYSTEM MOVES INTO THE AREA
BRINGING ANOTHER QUICK SURGE OF RAINFALL AND WINDS. RAINFALL
AMOUNTS LOOK TO RANGE FROM 0.5 INCHES TO 1.5 INCHES. WINDS LOOK
LIGHTER THAN WITH PREVIOUS SYSTEM...BUT THERE COULD BE SOME GUSTS
TO 40 MPH. THIS WILL BE A MUCH COLDER SYSTEM THAN THE PREVIOUS
SYSTEM. SNOW LEVELS WILL RISE AS THE SYSTEM COMES IN. INITIALLY
THEY LOOK TO BE AROUND 2500 FEET...BUT THEY WILL RISE THROUGH THE
EVENING. ACCUMULATING SNOW IS NOT EXPECTED BELOW 3500 FEET.
GIVEN THE FAIR AMOUNT OF QPF SUGGEST BY ALL MODELS AND THE LOWER
SNOW LEVELS EXPECTED TO BE FOCUSED OVER EASTERN TRINITY COUNTY
HAVE INTRODUCED A WINTER STORM WATCH FOR MODERATE TO HEAVY SNOW
ABOVE 3500 FEET. NOT CONFIDENT IN PRECISE ELEVATION OF WHERE SNOW
WILL ACCUMULATE BUT AT THIS POINT IT LOOKS LIKE MOST SNOW SHOULD
REMAIN ABOVE PASS LEVELS. MODEL GUIDANCE IS IN FAIR AGREEMENT
REGARDING THE OVERALL LONG TERM PATTERN...AND THAT IS THAT AN
ACTIVE STORM TRACK WILL CONTINUE TO RESULT IN A RAPID SUCCESSION
OF SHORTWAVE TROUGHS THROUGH THE AREA. WHILE THERE IS HIGH
CONFIDENCE THAT THIS WILL YIELD AN ABUNDANCE OF RAINFALL AND
LIKELY HIGH ELEVATION SNOW THROUGH THE NEXT 7 DAYS...BELOW AVERAGE
CONFIDENCE EXISTS REGARDING THE TIMING AND INTENSITY OF INDIVIDUAL
RAINY OR DRY PERIODS. MODEL GUIDANCE APPEARS TO BE IN RELATIVELY
GOOD AGREEMENT REGARDING A STORM SYSTEM THAT WILL IMPACT THE AREA
OVER THE WEEKEND...BEGINNING WITH LIGHT WARM FRONTAL RAIN AND
INCREASING WINDS FRIDAY EVENING FOLLOWED BY A PERIOD OF MORE
SUBSTANTIAL RAIN AND SHOWERS SATURDAY. BEYOND SATURDAY MODEL
SOLUTIONS DIVERGE SIGNIFICANTLY...AND ASIDE FROM A CONTINUATION OF
AN ACTIVE PATTERN...VERY LITTLE CAN BE SAID REGARDING THE DETAILS.
STILL...THE POTENTIAL EXISTS FOR A SUBSTANTIAL AMOUNT OF
PRECIPITATION THROUGH EARLY NEXT WEEK...PARTICULARLY IF THE MORE
PROGRESSIVE AND WETTER GFS SOLUTION IS CLOSER TO BEING ACCURATE.
&&
.AVIATION...MVFR CONDITIONS AND LIGHT TO MODERATE WINDS WILL CONTINUE
AT KCEC AND KACV THIS MORNING AS SHOWERS MOVE ACROSS THE REGION REDUCING
CEILINGS AND/OR VISIBILITIES. VFR CONDITIONS WILL OCCUR AT KCEC AND
KACV THIS AFTERNOON AS THE SHOWERS DIMINISH. MVFR CONDITIONS AND MODERATE
TO MODERATE AND GUSTY WINDS W3ILL PREVAIL AT KUKI THROUGH THIS AFTERNOON
AS SHOWERS MOVE THROUGH THE AREA AT TIMES REDUCING CEILINGS AND/OR
VISIBILITIES. VFR CONDITIONS AND LIGHT WINDS TO CALM CONDITIONS WILL
PREVAIL AT KUKI THIS EVENING AND TONIGHT AS THE SHOWERS DIMINISH ACROSS
THE AREA.
&&
.MARINE...WINDS AND SEAS WILL CONTINUE TO GRADUALLY DIMINISH THROUGH
TONIGHT IN THE WAKE OF A COLD FRONT AND AS A HIGH PRESSURE RIDGE BRIEFLY
BUILDS ACROSS THE REGION RELAXING THE PRESSURE GRADIENT. HOWEVER ANOTHER
OFFSHORE LOW PRESSURE SYSTEM WILL APPROACH WASHINGTON STATE AND SOUTHERN
CANADA THURSDAY. AN ASSOCIATED TRAILING COLD FRONT WILL MOVE THROUGH THE
WATERS THURSDAY. THESE SYSTEMS CONTINUE THE SERIES OF OFFSHORE LOW PRESSURE
SYSTEMS AND ASSOCIATED FRONTAL BOUNDARIES WHICH WILL CONTINUE TO IMPACT THE
COASTAL WATERS THIS WEEK AND EARLY NEXT WEEK. WINDS AND SEAS WILL INCREASE
THURSDAY AS THE COLD FRONT APPROACHES AND MOVES ACROSS THE AREA. AN
ELEVATED WESTERLY SWELL WILL CONTINUE PROPAGATING ACROSS THE WATERS THROUGH
THIS WEEKEND. SMALL CRAFT ADVISORIES WILL BE IN EFFECT ACROSS THE SOUTHERN
OUTER AND NEAR SHORE WATERS AND THE NORTHERN NEAR SHORE WATERS TODAY THROUGH
FRIDAY AND WILL LIKELY BE EXTENDED INTO THE WEEKEND. A SMALL CRAFT ADVISORY
WILL BE IN EFFECT ACROSS THE NORTHERN OUTER WATERS TODAY THROUGH EARLY
THURSDAY MORNING DUE TO WINDS AND SEAS. A GALE WARNING WILL BE IN EFFECT
ACROSS THE NORTHERN OUTER WATERS FROM EARLY THURSDAY MORNING THROUGH
THURSDAY EVENING DUE TO INCREASING WINDS. A SMALL CRAFT ADVISORY IS LIKELY
ACROSS THE NORTHERN OUTER WATERS FRIDAY THROUGH THIS WEEKEND.
