AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE EUREKA CA
242 PM PST TUE JAN 12 2010

.SYNOPSIS...LOW PRESSURE AND AN ASSOCIATED FRONTAL BOUNDARY WILL
BRING ANOTHER ROUND OF RAIN TO THE REGION TONIGHT INTO MIDDAY
WEDNESDAY. A FEW THUNDERSTORMS WILL ALSO BE POSSIBLE...ESPECIALLY
ALONG THE COAST AND SOUTH OF CAPE MENDOCINO. HIGH PRESSURE WILL
RETURN AND BRING DRY WEATHER THURSDAY AND FRIDAY.

&&

.DISCUSSION...SHORT TERM FOCUS REVOLVES AROUND PRECIPITATION CHANCES...
INTENSITY...AND THUNDERSTORM POTENTIAL TONIGHT INTO WEDNESDAY.
SYNOPTICALLY...AN UPPER LEVEL TROUGH WILL APPROACH THE COAST
OVERNIGHT. THE MODELS RA MAIN IN GOOD AGREEMENT WITH THIS SYSTEM
AND DISPLAY JUST SMALL DIFFERENCES IN RESPECT TO TIMING. THE
PRIMARY UPPER LEVEL JET WILL BE SITUATED TO OUR SOUTH OVER
CENTRAL AND SOUTHERN CALIFORNIA. HOWEVER...LATE TONIGHT AND EARLY
WEDNESDAY (MAINLY FROM 09Z-15Z) OUR FORECAST AREA WILL BE NEAR
THE LEFT EXIT OF THE JET...WHICH WILL ENHANCE UPPER DIVERGENCE
AND LIFT...AT LEAST BRIEFLY ENHANCING PRECIPITATION RATES OVER
HIGHER TERRAIN. WITH THE SHORTWAVE SLOWLY STRENGTHENING AS IT
PUSHES EAST AND COMBINES WITH A VORT MAX TRAVELING TO OUR SOUTH
...STEEP LAPSE RATES WILL LEAD TO DEVELOPMENT OF SCATTERED
THUNDERSTORMS...ESPECIALLY OVER THE SOUTHERN HALF OF OUR CWA. ANY
CONVECTION SHOULD REMAIN ELEVATED ALTHOUGH A FEW WEAK SURFACE-
BASED STORMS WILL BE POSSIBLE ALONG OR JUST BEHIND THE COLD
FRONT. NAM AND GFS MID LEVEL LAPSE RATES APPROACH 7C/KM OVER THE
COAST AND INTO INTERIOR MENDOCINO COUNTY FROM 14Z-18Z WEDNESDAY.
OVERALL..THE OPERATIONAL MODELS HAVE TRENDED SLIGHTLY FASTER WITH
FRONTAL PASSAGE...AND THE MAJORITY OF THE PRECIPITATION WILL BE
RAPIDLY PUSHING EAST AND OUT OF OUR AREA BY NOON WEDNESDAY.
SCATTERED TO NUMEROUS SHOWERS ARE EXPECTED TO PERSIST THROUGH THE
AFTERNOON HOURS WITH COLD AIR ALOFT AND REMNANT INSTABILITY. SNOW
LEVELS...INITIALLY MAINLY ABOVE 5K FT WILL DROP TO AROUND 4KT FT
BY AFTERNOON...BUT MUCH OF THE ORGANIZED AND HEAVIER
PRECIPITATION WILL HAVE EXITED BY THAT TIME. STILL...A FEW AREAS
ABOVE MAINLY 4500 FT MAY RECEIVE A COUPLE INCHES OF SNOW
ACCUMULATION. TOTAL QPF FOR THE NEXT 24 HOURS HAS TRENDED DOWN
SLIGHTLY...AND THIS SEEMS REASONABLE GIVEN THE SPEED OF THE
SYSTEM. MOST AREAS WILL RECEIVE ONE HALF TO ONE INCH OF RAINFALL
BY WEDNESDAY AFTERNOON...WITH LOCAL AMOUNTS IN EXCESS OF AN INCH
IN THE FAVORED HIGHER TERRAIN INCLUDING THE KING RANGE.

DRIER WEATHER WILL RETURN THURSDAY INTO FRIDAY WITH WEAK RIDGING
ALOFT AND AT THE SURFACE. PARTIAL CLEARING AND LIGHTER WINDS WILL
SET THE STAGE FOR VALLEY AND COASTAL FOG...ESPECIALLY DURING THE
NIGHTTIME AND MORNING HOURS. THE LULL IN ACTIVE WEATHER WILL BE
SHORT LIVED...WITH A RETURN TO A PROLONGED WET PERIOD SATURDAY
THROUGH EARLY NEXT WEEK AS SEVERAL POTENT FRONTAL SYSTEMS ARE
EXPECTED TO MOVE OUT OF THE EASTERN PACIFIC. A VERY STRONG
JET...NEARING 200KTS...WILL SEND DEEP MOISTURE AND A SERIES OF
RAIN EVENTS INTO THE WEST COAST EVERY 24 TO 36 HOURS. THE ECMWF
WAS THE MODEL OF CHOICE...FOLLOWED BY THE GFS. BETTWY

&&

.AVIATION...VFR CIGS THIS AFTN WILL GIVE WAY TO MVFR BY LATE THIS
EVENING AS ANOTHER BATCH OF RAIN MOVES ONSHORE. HEAVIER SHOWERS
WILL REDUCE CIGS/VSBYS TO IFR FOR BRIEF PERIODS WITH AN ISOLATED
TSTM NOT OUT OF THE QUESTION OVERNIGHT. SOUTH WINDS WILL GUST TO
30 KTS ALONG THE COAST...ESPECIALLY NEAR KCEC BEGINNING LATE THIS
EVENING. JCA

&&

.MARINE...WINDS AND SEAS HAVE SUBSIDED...IF ONLY FOR A BRIEF TIME. A
LOW PRESSURE SYSTEM MOVING ALONG THE OREGON COAST OVERNIGHT WILL
DRAG A COLD FRONT ACROSS THE WATERS. SOUTH WINDS WILL INCREASE
THIS EVENING AHEAD OF THE FRONT...WITH OCCASIONAL GALE FORCE
GUSTS EXPECTED IN THE NORTHERN WATERS. A WELL ADVERTISED LARGE
WEST SWELL WILL ENTER THE WATERS THIS EVENING. MODEL GUIDANCE HAS
OVERESTIMATED THE TOTAL WAVEHEIGHTS (BY AS MUCH AS 5 FT) BUT WE
STILL EXPECT THE SWELL TO PEAK EARLY WED MORNING AROUND 19 FT AT
16 SEC. JCA

&&
