AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
521 AM PST TUE JAN 19 2016
.SYNOPSIS...ANOTHER STORM SYSTEM IS MOVING ONSHORE THIS MORNING.
WIDESPREAD RAINFALL IS EXPECTED...WITH LIGHTER AMOUNTS THAN THE
STORM SYSTEM ON SUNDAY. WINDS WILL BECOME GUSTY THIS MORNING WITH
THE STRONGEST WINDS AROUND MIDDAY. MORE RAINS AND MOUNTAIN SNOWS
ARE EXPECTED TO RETURN ON THURSDAY NIGHT AND FRIDAY.
&&
.SHORT TERM...WATER VAPOR SHOWS A SHORTWAVE AND ASSOCIATED SURFACE
LOW APPROACHING THE AREA THIS MORNING. THE FRONTAL BOUNDARY IS
MOVING ONSHORE AND BRINGING RAIN TO THE AREA. THE SURFACE LOW IS
RAPIDLY APPROACHING THE COAST. PRESSURE FALLS AT THE BUOYS AND
THE ONSHORE ARE RATHER IMPRESSIVE...UP TO AROUND 2 MB PER HOUR.
MODELS ARE SHOWING 55 TO 60 KT AT 925 MB. WV SAT SHOWS SOME DRIER
AIR BEHIND THE FRONTAL BOUNDARY. THIS WOULD INDICATE THAT SOME OF
THE STRONGER 925 MB WINDS ARE BEING BROUGHT TO THE SURFACE. SO
HAVE ISSUED A WIND ADVISORY. IF YOU LOOK STRICTLY AT THE SURFACE
WINDS IT LOOKS LIKE IT WILL BE A LOW END ADVISORY WITH ONLY A FEW
GUSTS TO 45 MPH IN THE MOST EXPOSED AREAS. HOWEVER IF SOME OF THE
STRONGER WINDS ARE BROUGHT TO THE SURFACE...OR AT LEAST THE
RIDGES...WE COULD GET GUSTS AS HIGH AS 50 TO 60 MPH. RAINFALL
AMOUNTS LOOK TO BE HIGHER THAN PREVIOUSLY EXPECTED. WENT WITH THE
WPC QPF FOR TODAY AND THIS MORNING IT HAS OVER AN INCH FOR
MENDOCINO COUNTY. THIS MAY CAUSE RIVERS TO RISE MORE QUICKLY THAN
PREVIOUSLY EXPECTED. WITH THE RECENT RAINS RIVERS SUCH AS THE
NAVARRO WOULD BE STARTING OFF CLOSER TO FLOOD STAGE.
LATER THIS AFTERNOON THE RAIN WILL TAPER OFF TO SHOWERS AS THE
FRONTAL BOUNDARY MOVES OFF THE NORTHEAST. WEDNESDAY AND THURSDAY
ARE NOW LOOKING MAINLY DRY AS THE MODELS HAVE SLOWED DOWN THE NEXT
SYSTEM. MADE SOME FAIRLY DECENT ADJUSTMENTS TO THE POPS THIS
MORNING TO LOWER THEM ON THESE DAYS.
NOW IT LOOKS LIKE THE NEXT CHANCE FOR RAIN WILL BE THURSDAY LATE
IN THE AFTERNOON THROUGH FRIDAY MORNING. FRIDAY AFTERNOON THE NEXT
SYSTEM STARTS TO MOVE INTO THE AREA. THIS WILL BRING ADDITIONAL
RAIN AND GUSTY WINDS. THE GFS HAS ANOTHER SURFACE LOW FORMING OFF
THE COAST AND APPROACHING THE AREA...BUT THIS IS STILL SEVERAL
DAYS OUT AND IT MAY MOVE FARTHER NORTH AS IT GETS CLOSER. FRIDAY
NIGHT THIS SYSTEM LOOKS TO BRING ADDITIONAL HEAVY RAIN TO THE
AREA. MKK
.LONG TERM (SATURDAY THROUGH MONDAY)...A COLDER UPPER TROUGH WILL
PROLONG THE POSSIBILITY FOR PRECIPITATION ON SATURDAY AS THE STORM
SYSTEM LIFTS OVER THE PACIFIC NORTHWEST BY SATURDAY NIGHT. SNOW
LEVELS WILL FALL TO 3000-3500 FT BY SATURDAY NIGHT. MODELS THEN
SIGNAL FOR LONG WAVE RIDING TO DEVELOP OVER THE WESTERN UNITED
STATES BRINGING DRY WEATHER TO THE REGION AND A SUBTLE WARMING
TREND OF JUST A DEGREE OR TWO. KML
&&
.AVIATION...PERIODS OF MODERATE TO HEAVY RAIN AND GUSTY WINDS IS
EXPECTED THIS MORNING AS A FRONTAL BOUNDARY MOVES THROUGH. THIS
WILL BRING PERIODS OF MVFR CONDITIONS. WIND GUSTS TO 30 TO 40 KT
ARE POSSIBLE ALONG THE COAST AS THIS BOUNDARY MOVES INLAND THIS
MORNING. THIS AFTERNOON WINDS WILL DIMINISH AND CONDITIONS WILL
BECOME MORE SHOWERS. TONIGHT THE COASTAL AREAS WILL MAINLY SEE
MVFR CONDITIONS WITH SOME MID LEVEL CLOUDS LINGERING IN THE LATE
EVENING. LATE TONIGHT THE CLOUDS ARE EXPECTED TO
DISSIPATE...HOWEVER GROUND FOG MAY FORM IS CLOUDS CLEAR OUR. FOR
NOW HAVE HELD OFF ON ADDING LOW CLOUDS/FOG AT THE COAST. INLAND
AREAS WILL LIKELY SEE LOW LEVEL CLOUDS AND POSSIBLE FOG. MKK
&&
.MARINE...A PASSING FRONT WILL BRING A QUICK SHOT OF GALE FORCE
WINDS TO THE COASTAL WATERS THIS MORNING. GALE WARNINGS NOW EXIST
ACROSS THE WATERS UNTIL THE EARLY AFTERNOON. NEARSHORE CONDITIONS
WILL BE MORE MARGINAL WITH HIGHEST GUSTS NEAR 40 KT MOSTLY AROUND
CAPE MENDOCINO AND OCCASIONAL GUSTS NEAR 45 KT FARTHER OFFSHORE.
WINDS WILL QUICKLY DECREASE BEHIND THE FRONT THIS AFTERNOON.
ADDITIONAL DISTURBANCES WILL IMPACT THE REGION THIS WEEK BRINGING
INCREASING SOUTH WINDS AND BUILDING SHORT PERIOD WAVES WITH BRIEF
PERIODS IMPROVEMENT BETWEEN SYSTEMS. OTHERWISE THE WESTERLY SWELL
WILL GRADUALLY DIMINISH OVER THE NEXT FEW DAYS BEFORE ANOTHER
SWELL IMPACTS THE WATERS CAUSING THE SEA STATE TO APPROACH 16 TO
18 FT THURSDAY AND FRIDAY. SMALL CRAFT ADVISORIES WILL LIKELY BE
NEEDED AFTER THE GALES THIS AFTERNOON AS THE SEA STATE REMAINS
ELEVATED. GALES MAY BE NECESSARY AS SOUTH WINDS INCREASE MID-WEEK.
