AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
432 AM PDT TUE MAR 15 2016

.SYNOPSIS...BUILDING HIGH PRESSURE WILL BRING WARMING TEMPERATURES
AND DRY WEATHER OVER THE NEXT FEW DAYS. RAIN CHANCES WILL RETURN
THIS WEEKEND AND EARLY NEXT WEEK AS HIGH PRESSURE BREAKS DOWN AND
ALLOWS UPPER LEVEL DISTURBANCES TO IMPACT THE AREA.

&&

.DISCUSSION...HIGH PRESSURE WILL BUILD OVER THE PACIFIC NORTHWEST
OVER THE NEXT FEW DAYS BRINGING WARMING TEMPERATURES AND MOSTLY
DRY WEATHER TO NORTHERN CALIFORNIA. MID TO UPPER LEVEL CLOUDS WILL
STREAM ACROSS THE REGION EARLY TODAY. THERE WILL BE A CHANCE FOR A
LIGHT RAIN SHOWER THIS MORNING BUT MOSTLY ACROSS DEL NORTE
COUNTY. THEN CLOUD COVER SHOULD DIMINISH TONIGHT AS THE MOIST
ZONAL FLOW DRIES OUT WITH BUILDING HIGH PRESSURE. WEDNESDAY AND
THURSDAY SHOULD BE VERY PLEASANT WITH MOSTLY SUNNY SKIES AND
REGION WIDE TEMPERATURES IN THE 60S AND 70S. THERE WILL BE A
POSSIBILITY FOR SOME COASTAL AND VALLEY CLOUDS TO DEVELOP EARLY
WEDNESDAY AND THURSDAY MORNING BUT DRY EASTERLY FLOW OVERNIGHT
SHOULD HELP KEEP THIS MINIMAL.

A CHANCE FOR RAIN WILL RETURN THIS WEEKEND THROUGH EARLY NEXT
WEEK AS THE UPPER RIDGE BEGINS TO BREAK DOWN WITH THE APPROACH OF
A DEEP TROUGH OVER THE EASTERN PACIFIC. THIS WILL CAUSE A COOLING
TREND IN TEMPERATURES AND CLOUD COVER TO INCREASE ACROSS THE
REGION THROUGH THE WEEKEND. MODELS CONTINUE TO SHOW THE
POSSIBILITY FOR MULTIPLE SHORTWAVES IMPACTING THE REGION FROM
FRIDAY NIGHT THROUGH TUESDAY. THE FIRST WAVE COMES IN THE FORM OF
A WEAKENING FRONT FRIDAY NIGHT...WITH A MORE SUBSTANTIAL SYSTEM
FOR SUNDAY AND MONDAY. AS OF NOW PRECIPITATION TOTALS FOR FRIDAY
AND SATURDAY LOOK TO BE VERY LIGHT THAT IS IF ANY FALLS AT ALL. I
AM STILL VERY SKEPTICAL FOR THESE TWO DAYS AS THE RIDGE WILL HAVE
THE CAPABILITY OF OBLITERATING THESE WEAK FRONTS. THE SYSTEM FOR
SUNDAY AND MONDAY LOOKS MORE POTENT AND CAPABLE OF DROPPING AN
INCH OR TWO OF RAIN. CONFIDENCE REMAINS LOW THIS FAR IN ADVANCE
SO KEPT POPS LOWER ON FRIDAY AND SATURDAY BUT INCREASED POPS JUST
ABOVE CLIMO LATE IN THE WEEKEND. KML

&&

.AVIATION...MULTI-LAYERED CLOUDINESS CONTINUES TO STREAM OVER THE
AREA. MUCH OF THE CLOUDS HAVE BEEN IN THE MID LAYERS ALTHO CLOUD
HEIGHTS AS LOW AS 6 KFT HAVE BEEN REPORTED AT KCEC. HIGHER CLOUDS
COVERED KUKI EARLIER IN THE NIGHT...BUT THESE CLOUDS ARE CURRENTLY
SHIFTING SE. SOME GROUND FOG REMAINS POSSIBLE AT KUKI IF IT CAN
DEVELOP DURING THE CLOUD BREAKS. A FEW LIGHT SHOWERS ARE POSSIBLE
NEAR KCEC DURING THE MORNING HOURS. WINDS WILL BE LIGHT. /SEC

&&

.MARINE...HE FORECAST WILL BE DOMINATED BY SWELL. THE CURRENT W TO
NW SWELL TRAIN WILL GRADUALLY SUBSIDE OVER THE NEXT COUPLE OF DAYS.
THE SMALL CRAFT ADVISORY FOR THIS SWELL HAS BEEN EXTENDED FOR A FEW
MORE HOURS INTO THIS EVENING ACROSS THE WATERS. A FRESH BATCH OF W
SWELL WILL ARRIVE LATE IN THE WEEK. WINDS WILL BE GENERALLY LIGHT
THRU THE PERIOD. HOWEVER...NORTHERLY WINDS ARE EXPECTED TO INCREASE
WEDNESDAY AFTERNOON AND EVENING AS HIGH PRESSURE BUILDS OVER THE E
PACIFIC AND AN INLAND THERMAL TROF SHARPENS. WINDS MAY REACH
ADVISORY CRITERIA IN THE OFFSHORE WATERS...BUT THE WIND INCREASE
WILL BE SHORT-LIVED WITH LIGHTER WINDS RETURNING BY LATE WEEK.

&&

.HYDROLOGY...RAIN HAS PRETTY MUCH COME TO A HALT WITH DRY WEATHER
EXPECTED TO PREVAIL OVER THE NEXT FEW DAYS. THE EEL RIVER AT
FERNBRIDGE IS THE ONLY REMAINING RIVER IN MONITOR STAGE IS AND
FORECAST TO FALL BELOW MONITOR STAGE LATER THIS MORNING. PLEASE
