AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
617 AM PST SUN NOV 30 2014

.SYNOPSIS...WET AND UNSETTLED WEATHER WILL CONTINUE THROUGH THE
MIDDLE OF THIS WEEK AS A LOW PRESSURE SYSTEM SLOWLY MOVES TOWARD
THE CALIFORNIA COAST.

&&

.DISCUSSION...A WARM FRONT WILL SHIFT NORTH OVER NORTHWEST
CALIFORNIA TODAY AS AN UPPER LEVEL SHORTWAVE MOVES INTO CENTRAL
CALIFORNIA. THIS COMBINATION HAS TRIGGERED SHOWER ACTIVITY OVER
MENDOCINO COUNTY WHICH WILL EXPAND NORTH WHILE WEAKENING AS THE
UPPER LEVEL SHORTWAVE MOVES EAST OF THE AREA. THE BEST CHANCES FOR
ACCUMULATING RAIN WILL BE OVER MENDOCINO...SOUTHERN HUMBOLDT...AND
TRINITY COUNTIES TODAY. HAVE MAINTAINED SLIGHT CHANCES ACROSS THE
REMAINDER OF THE AREA THIS AFTERNOON AS THE WARM FRONT MOVES
OVERHEAD BUT ACTIVITY SHOULD BE MINIMAL.

NORTHWEST CALIFORNIA WILL BE WITHIN THE WARM SECTOR OF A DEVELOPING
UPPER LOW OFF THE CENTRAL CALIFORNIA COAST ON MONDAY. MOIST
SOUTHERLY FLOW WILL ALLOW ISOLATED TO SCATTERED SHOWERS TO FORM
ACROSS THE REGION AND STREAM NORTHWARD. HOWEVER WITH LITTLE TO
TRIGGER SHOWER ACTIVITY ON MONDAY A RELATIVELY DRY DAY IS EXPECTED
BEFORE HEAVIER RAIN APPROACHES THE COAST AHEAD OF THE UPPER LOW
MONDAY NIGHT INTO TUESDAY.

DIFFLUENT FLOW AHEAD OF THE UPPER LOW WILL PROMOTE RAIN AND
CONVECTIVE DEVELOPMENT SOUTHWEST OF THE REGION MONDAY NIGHT. THIS
RAIN SHIELD WILL SHIFT NORTH INTO TUESDAY BRINGING ALL OF NORTHWEST
CALIFORNIA AT LEAST SOME RAIN BY TUESDAY NIGHT. THE HEAVIEST
PRECIPITATION WILL LIKELY BE TARGETED AT MENDOCINO COUNTY AND TO THE
SOUTH. STUCK CLOSE TO WEATHER PREDICTION CENTER GUIDANCE FOR
RAINFALL ON TUESDAY WHICH PREDICTS NEARLY AN INCH OF RAIN ACROSS
MUCH OF SOUTHERN MENDOCINO COUNTY OVER A 24 HOUR PERIOD ENDING
TUESDAY NIGHT AT MIDNIGHT...THOUGH THIS MAY BE CONSERVATIVE. MODELS
INDICATE SOME INSTABILITY WILL BE PRESENT AS THE BAND OF
PRECIPITATION MOVES OVER THE REGION WHICH COULD RESULT IN A CLAP OF
THUNDER OR TWO.

ADDITIONAL SHOWERS WILL LINGER THROUGH WEDNESDAY AS THE UPPER LOW
FINALLY MOVES INLAND AND THEN EAST OF THE AREA. ONCE AGAIN...WEAK
INSTABILITY MAY ALLOW A THUNDERSTORM OR TWO TO FORM BUT THE BEST
DYNAMICS BY THE AFTERNOON HOURS WILL BE JUST EAST OF THE AREA OVER
THE CENTRAL VALLEY AND SIERRAS.

BROAD WEST TO SOUTHWEST FLOW WILL PERSIST INTO THE WEEKEND AS A WEAK
TROUGH DEVELOPS OFF THE WEST COAST BEHIND THE DEPARTING UPPER LOW.
SOME LIGHT SHOWERS MAY CONTINUE TO DEVELOP OVER THE REGION WITHIN
THE MOIST AIR MASS. THUS CHANCES FOR PRECIPITATION HAVE BEEN
CONTINUED AT OR JUST ABOVE CLIMATOLOGY THROUGH THE END OF THE WEEK.

&&

.AVIATION...VFR CONDITIONS AND LIGHT WINDS WILL CONTINUE AT KCEC AND
KACV THIS MORNING. HOWEVER CLOUDINESS WILL INCREASE TODAY AND
OVERNIGHT AS A WARM FRONT MOVES NORTHWARD RESULTING IN MVFR
CONDITIONS THIS EVENING AND OVERNIGHT. IFR TO LIFR CONDITIONS WILL
CONTINUE AT KUKI THROUGH THIS MORNING AS THE WARM FRONT MOVES
NORTHWARD PRODUCING SHOWERS AND LIGHT RAIN WHICH IS REDUCING
CEILINGS AND/OR VISIBILITIES. THE SHOWERS WILL DECREASE THIS
AFTERNOON AND EVENING AND VFR TO MVFR CONDITIONS AND LIGHT WINDS TO
CALM CONDITIONS WILL PREVAIL AT KUKI TONIGHT.

&&

.MARINE...THE COASTAL WATERS WILL BE IMPACTED BY A SERIES OF LOW
PRESSURE SYSTEMS AND ASSOCIATED FRONTS THROUGH THE MIDDLE OF THIS
WEEK. THESE SYSTEMS WILL BUILD STEEP WIND DRIVEN WAVES ACROSS THE
WATERS AT TIMES. A SMALL CRAFT ADVISORY CONTINUES ACROSS THE
NORTHERN OUTER WATERS THROUGH THIS MORNING DUE TO ELEVATED SEAS.
SMALL CRAFT ADVISORIES WILL BE IN EFFECT ACROSS THE OUTER WATERS
MONDAY DUE TO INCREASING WINDS AND STEEP SEAS.
