AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
438 AM PDT SUN MAR 13 2011

.SYNOPSIS...A FRONT WILL BRING HEAVY RAINFALL AND GUSTY WINDS TO
THE AREA THROUGH TONIGHT. THE WET WEATHER PATTERN WILL
CONTINUE NEXT WEEK.

&&

.DISCUSSION...A STRONG COLD FRONT APPROACHING THE AREA WILL
MODERATE TO HEAVY RAIN THROUGH MUCH OF THE DAY TO THE REGION.
RADAR AND SURFACE OBSERVATIONS LIGHT PRECIP STARTING ACROSS THE
AREA AS OF 4AM. THE EUREKA AREA AND EEL RIVER VALLEY REMAINS DRY AT
THIS POINT DUE TO THE DOWN-SLOPING OFF THE KING RANGE. EXPECT
PRECIP WILL SPREAD ACROSS THE REST OF THE AREA BY AROUND SUNRISE.
PWATS ACCORDING TO MODELS AND SHOWN ON SATELLITE ARE NEAR TO
SLIGHTLY ABOVE 1 INCH WITH A GOOD TROPICAL CONNECTION. QPF LOOKS
TO BE AROUND AN INCH WITH UP TO 3 INCHES IN POSSIBLE IN FAVORED
AREAS. A 125 KT JET OVERHEAD SHOULD HELP PROVIDE SOME ADDITIONAL
LIFT. SNOW LEVELS AHEAD OF THE FRONT AND WITH THE MAJORITY OF THE
PRECIP ARE OVER 5000 FT. MODELS ARE IN GOOD AGREEMENT ON THE FRONT
PASSING THROUGH EUREKA AROUND 00Z TODAY. MODELS ARE SHOWING ENOUGH
INSTABILITY FOR SOME ISOLATED THUNDERSTORMS NORTH OF TRINIDAD AND
OVER THE NORTHERN WATERS SO ADDED THEM TO THE FORECAST FOR LATE
AFTERNOON AND EVENING. WIND ADVISORY STILL LOOKS ON TRACK FOR THE
REDWOOD COAST. BEHIND THE FRONT SNOW LEVELS FALL TO AROUND 3500
FT...BUT THE MAJORITY OF THE PRECIP WILL BE OVER BY THIS TIME AND
SNOW AMOUNTS WILL BE WELL BELOW ADVISORY LEVELS. SHOWERS WILL
CONTINUE THROUGH THE NIGHT AND TAPER OFF ON MONDAY.

MONDAY NIGHT INTO TUESDAY THE GFS AND ECMWF ARE IN GOOD AGREEMENT ON
ANOTHER FRONT APPROACHING THE AREA. A COUPLE ADDITIONAL IMPULSES
MOVE THROUGH TUESDAY AND TUESDAY NIGHT BRINGING SIGNIFICANT
RAINFALL TO THE AREA. SNOW LEVELS WILL INITIALLY BE AROUND 5000 FT
AND GRADUALLY FALL TO AROUND 3000 FT AS EACH IMPULSE MOVES
THROUGH. WITH THE SIGNIFICANT PRECIP EXPECTED TODAY THE RIVERS WILL
BE ALREADY BE RUNNING HIGHER THAN NORMAL FOR THIS NEXT ROUND OF
RAIN. THIS WILL NEED TO MONITORED AS IT GETS CLOSER.

THURSDAY MODELS SHOW ANOTHER WAVE MOVING THROUGH ALTHOUGH THERE
DIFFERENCES IN THE TIMING AND STRENGTH. FRIDAY AND INTO THE
WEEKEND THE GFS AND ECMWF ARE SHOWING AN UPPER LEVEL LOW MOVING
DOWN OFF THE COAST. AS IS TYPICAL WITH THIS TYPE OF SYSTEM MODELS
ARE NOT IN GREAT AGREEMENT AND A SLIGHT CHANGE IN THE TRACK OF THE
LOW CAN MEAN SIGNIFICANT DIFFERENCES IN THE WEATHER. SO FOR NOW
HAVE POPS NEAR CLIMO FOR NEXT WEEKEND.

&&

.AVIATION...A STORM PASSING N OF THE REGION WILL PUSH A FRONT ACROSS
CWA THIS AFTERNOON. -RA AHEAD OF THIS SYSTEM BEGINNING ACROSS CWA
EARLY THIS MORNING. EXPECT CIGS TO LOWER TO MVFR THIS MORNING AND
PERSIST THROUGH THE DAY WITH MVFR TO IFR VSBYS EXPECTED IN HEAVIER
PRECIP. IN ADDITION TO PRECIP...S WINDS WILL INCREASE. MODELS SHOW
BL WINDS PEAKING AROUND 60-70KT OVER CEC AS THE FRONT MOVES THROUGH
THIS AFTERNOON...SO WILL CONTINUE MENTION OF LLWS. BUFKIT FCST
SOUNDINGS SHOW STEEPENING MID LEVEL LAPSE RATES AS UPPER TROUGH
PUSHES FRONT THROUGH WITH ISOLD TSTMS POSSIBLE LATE AFTERNOON/EARLY
EVENING MAINLY OVER THE WATERS AND REDWOOD COAST N OF HWY 299.
PRECIP WILL BECOME SHOWERY AND WINDS WILL DIMINISH OVERNIGHT AS THE
FRONT PUSHES E OF THE AREA.

&&

.MARINE...S WINDS WILL CONTINUE TO INCREASE THIS MORNING AHEAD OF
AN APPROACHING FRONT. NAM AND GFS REMAIN IN GOOD AGREEMENT WITH
