AREA FORECAST DISCUSSION...CORRECTION
NATIONAL WEATHER SERVICE
EUREKA CA 456 AM PST THU NOV 19 2015

.SYNOPSIS...A COLD FRONT WILL APPROACH THE AREA TODAY WITH
INCREASING RAIN CHANCES MAINLY NORTH OF CAPE MENDOCINO. DRY
WEATHER WILL RETURN ON FRIDAY AND CONTINUE THROUGH THE WEEKEND.
ANOTHER STORM SYSTEM WILL BRING RAINS AND MOUNTAIN SNOWS TO THE
AREA FROM MONDAY NIGHT THROUGH WEDNESDAY. TEMPERATURES WILL BE
NEAR TO SLIGHTLY ABOVE NORMAL THROUGH THE WEEKEND WITH COLDER THAN
NORMAL READINGS RETURNING BY NEXT TUESDAY.

&&

.DISCUSSION...A COLD FRONT AND ATTENDANT WEAK UPPER LEVEL
DISTURBANCE WILL CONTINUE TO SHIFT S TOWARD THE AREA THIS MORNING
WITH INCREASING RAINFALL N OF CAPE MENDOCINO. LIGHT DRIZZLE WILL
PRECEDE THE HEAVIER RAINFALL ALONG THE REDWOOD COAST AND OVER THE
NORTH COAST INTERIOR MOUNTAINS PER INCREASED LOW LEVEL FLUX
CONVERGENCE AND UPWARD VERTICAL VELOCITY. RAINFALL TOTALS FROM
THIS SYSTEM ARE EXPECTED TO AVERAGE AROUND ONE HALF INCH WITH
LOCALLY HIGHER AMOUNTS OF OVER ONE INCH POSSIBLE ALONG S AND SW
FACING TERRAIN OF DEL NORTE COUNTY. THERE WILL BE SOME WEAK
DOWNSLOPING AND RAIN SHADOWING ALONG PORTIONS OF THE REDWOOD COAST
DURING THE EVENT WHICH WILL KEEP RAINFALL TOTALS SLIGHTLY LOWER.

A WEAK HIGH PRESSURE RIDGE ALOFT WILL BUILD OVER THE AREA ON FRI
WITH IMPROVING CONDITIONS. FORECAST MODELS HAVE COME INTO BETTER
AGREEMENT WITH AN UPPER LOW DROPPING S OVER THE E PACIFIC ON SAT.
THE POSITION FARTHER OFFSHORE SHOULD KEEP MOST RAINS AWAY FROM THE
COAST.

A MORE SUBSTANTIAL UPPER TROF WILL DIG S ALONG THE W COAST MON
AND TUE WITH INCREASING RAIN CHANCES ACROSS OUR AREA BY MON NIGHT.
THE MODELS ARE COMING INTO BETTER AGREEMENT WITH THE TIMING AND
STRENGTH OF THIS STORM SYSTEM. HOWEVER...THERE IS MUCH UNCERTAINTY
WITH RESPECT TO PRECIP AMOUNTS. BOTH THE GFS AND ECMWF DEPICT THE
BULK OF THE QPF WITH THIS SYSTEM WILL IMPACT THE AREA EARLY TUE
MORNING THRU TUE AFTERNOON...WITH MORE SHOWERY PRECIP THEREAFTER.
SNOW LEVELS WILL BE ON THE DECLINE DURING THE DAY TUE AS THE UPPER
TROF SHIFTS OVER THE AREA. HOWEVER...THERE DOESN'T APPEAR TO BE A
TROPICAL CONNECTION WITH THIS SYSTEM...AND IN FACT THE W PORTION
OF THE STORM SYSTEM IS QUITE DRY. DYNAMIC FORCING AND MOISTURE
WITHIN THE TROF ITSELF LOOK TO BE RESPONSIBLE FOR MOST OF THE
PRECIP. HAVE HIGHLIGHTED GENERAL WINTER WX CONDITIONS OVER THE
INTERIOR ZONES IN THE HWO...BUT WILL HOLD OFF ON ANY SNOWFALL
AMOUNT PREDICTIONS FOR NOW. DUE TO THE COLD AIR ALOFT WITH THIS
SYSTEM...SMALL HAIL WILL BE POSSIBLE IN HEAVIER SHOWERS STARTING
TUE AFTERNOON.

TEMPERATURES ARE EXPECTED TO BE NEAR TO SLIGHTLY ABOVE NORMAL THRU
THE UPCOMING WEEKEND. AS THE UPPER TROF DIGS OVER THE AREA EARLY
NEXT WEEK...TEMPERATURES WILL DROP BELOW NORMAL BY TUE. /SEC

&&

.AVIATION...A WEAK COLD FRONT APPROACHING THE AREA IS INCREASING
CLOUDINESS AND SHOWERS WILL MOVE ACROSS THE AREA AT TIMES AT KCEC
AND KACV TODAY. MVFR TO IFR CONDITIONS AND LIGHT WINDS TO CALM
CONDITIONS WILL CONTINUE AT KCEC AND KACV TODAY. THE LOWER
CONDITIONS WILL BE DUE TO REDUCED CEILINGS AND/OR VISIBILITIES.
VFR CONDITIONS AND LIGHT WINDS TO CALM CONDITIONS WILL CONTINUE AT
KUKI TODAY.

&&

.MARINE...A WEAK COLD FRONT WILL MOVE INTO THE WATERS THIS
EVENING. SEAS WILL CONTINUE TO GRADUALLY DIMINISH TODAY IN ADVANCE
OF THE FRONT AS THE PRESSURE GRADIENT RELAXES. LIGHT WINDS WILL
CONTINUE ACROSS THE NEAR SHORE WATERS THIS WEEK. LIGHT TO MODERATE
WINDS WILL PREVAIL ACROSS THE OUTER WATERS THIS WEEK. SEAS WILL
GRADUALLY DIMINISH THROUGH THIS WEEKEND. SEAS WILL INCREASE MONDAY
AS AN OFFSHORE HIGH PRESSURE SYSTEM STRENGTHENS INCREASING THE
PRESSURE GRADIENT ACROSS THE WATERS.
