AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PORTLAND OR
906 AM PST TUE NOV 20 2012
.SYNOPSIS...A VERY MOIST FRONTAL ZONE CONTINUES TO LINGER ACROSS
WESTERN OREGON...WITH HEAVY RAIN CONTINUING TO IMPACT EASTERN
LANE...LINN...AND MARION COUNTIES EARLY THIS MORNING. A COOL BREEZY
AND SHOWERY WEATHER REGIME WILL MOVE IN LATER TODAY THROUGH
WEDNESDAY. WITH THE COLDER AIR MASS SNOW WILL ONCE AGAIN AFFECT THE
CASCADE PASSES TONIGHT AND WEDNESDAY...BEFORE TAPERING OFF WEDNESDAY
NIGHT. THANKSGIVING DAY WILL LIKELY BE DRY...BUT MORNING FOG WILL
PROBABLY LINGER IN THE VALLEYS. THE NEXT PACIFIC FRONT WILL MOVE IN
FRIDAY BRINGING MORE RAIN AND MOUNTAIN SNOW TO THE PACIFIC NORTHWEST.
&&
.SHORT TERM...HEAVY RAIN AND MOUNTAIN SNOW IS JUST ABOUT TO CLEAR THE
EASTERN PART OF THE FORECAST AREA THIS MORNING. HOWEVER... ADDITIONAL
RAIN IS ALREADY MOVING IN OFF THE PACIFIC FROM THE NEXT SYSTEM. THIS
NEXT SYSTEM WILL BE WEAKER AND COLDER THAN THE LAST SO HIGH WINDS ARE
NOT A CONCERN. STILL...EXPECT TO SEE SOME GUSTS TO 45 MPH ALONG THE
COAST TODAY ESPECIALLY NEAR SHOWERS.
ANOTHER COLD WAVE OF LOW PRESSURE WILL MOVE ONSHORE WED MORNING...
FOLLOWED BY A RIDGE OF HIGH PRESSURE COMING IN FROM THE SOUTH. THERE
MAY BE SUFFICIENT SOUTH-NORTH PRESSURE GRADIENTS FOR GUSTS TO 50 MPH
ALONG THE COAST BUT DAMAGING WINDS ARE NOT EXPECTED. WINDS WILL ALSO
BE GUSTY INLAND WITH THIS SYSTEM...ESPECIALLY NEAR HEAVIER SHOWERS.
AS COLDER AIR MOVES IN...SNOW LEVELS WILL LOWER AS WELL. SNOW
LEVELS...CURRENTLY AT PASS LEVELS...WILL LOWER TO AROUND 3000-3500 FT
BY WED MORNING. WITH SHOWERS CONTINUING TO MOVE ONSHORE AND GOOD
WESTERLY FLOW...WE COULD SEE ACCUMULATIONS CLOSE TO THE 6 INCH/12 HR
RATE REQUIRED FOR A SNOW ADVISORY WED. SHOWERS WILL TAPER OFF
EVERYWHERE AS HIGH PRESSURE BUILDS IN LATER WEDNESDAY AND WED NIGHT.
LIGHT WIND AND RIDGING ALOFT WILL PROVIDE NEAR IDEAL CONDITIONS FOR
FOG FORMATION THU MORNING. CUT BACK POPS SIGNIFICANTLY FOR
THANKSGIVING DAY AS FLAT RIDGING SHOULD KEEP US DRY FOR THE DAY.
WEAGLE
.HYDROLOGY...COASTAL RIVERS HAVE CRESTED AND SEVERAL THAT HAD
FLOODED HAVE DROPPED BELOW FLOOD STAGE. FLOODING CONTINUES ALONG THE
GRAYS...AND LOWER NEHALEM. ALL COASTAL RIVERS
SHOULD BE BELOW FLOOD STAGE BY THIS AFTERNOON. INLAND...FLOODING
CONTINUES ALONG THE MARYS RIVER NEAR CORVALLIS.
.LONG TERM...NO CHANGES. PREVIOUS DISCUSSION FOLLOWS...
THURSDAY EVENING THROUGH MONDAY...NEXT FRONT AND ASSOCIATED
PRECIPITATION WILL BEGIN TO AFFECT THE REGION THURSDAY NIGHT. THE
PRECIPITATION LOOKS TO PERSIST THROUGH FRIDAY NIGHT AS THE FRONT WILL
BE SLOW TO MOVE ACROSS THE AREA. SIGNIFICANT MODEL DISCREPANCIES
CROP UP WITH THIS SYSTEM BY SATURDAY...MOSTLY IN TERMS OF PLACEMENT
OF MOISTURE FEEDS PUSHING ONSHORE. SUNDAY AND BEYOND...MODELS
CONTINUE TO ADVERTISE A LONG WAVE TROUGH BEING CARVED OUT OVER THE
CENTRAL CONUS...AS A RIDGE BUILDS OVER THE EASTERN PACIFIC. THE PAC
NW LOOKS TO BE BETWEEN THESE SYSTEMS...BUT CONFIDENCE IS LOW FOR ANY
PARTICULAR SOLUTION AT THIS TIME. PRECIPITATION CHANCES SATURDAY
NIGHT THROUGH MONDAY ARE HIGHLY UNCERTAIN...HOWEVER CONFIDENCE IS
FAIR THAT TEMPERATURES WILL BE NEAR NORMAL. OTHERWISE...DUE TO LOW
CONFIDENCE...DID NOT MAKE MAJOR CHANGES TO THE PREVIOUS FORECAST.
&&
.AVIATION...CLUSTER OF SHOWER ACTIVITY MOVING ONSHORE WILL BRING
GUSTY WINDS AND A PROBABLE DROP TO MVFR CIGS AT TIMES THIS
MORNING. ANOTHER SYSTEM MOVES ONSHORE TONIGHT BUT AGAIN CIGS DO
NOT APPEAR TO DROP MUCH BELOW MVFR. VSBYS MAY FALL TO IFR THOUGH
UNDER BOTH EVENTS. GENERALLY MAIN IMPACT WILL BE INCREASING SOUTH
WINDS TODAY AND AGAIN LATER TONIGHT WITH GUST POTENTIAL OF 35 TO
40 KT ALONG THE COAST AND PROBABLY 25 TO 30 KT INLAND.
PDX AND APPROACHES...CIGS EXPECTED TO HOVER AROUND 3000 FEET AS
THE SHOWER COMPLEX MOVES NEARBY. DONT THINK THERE WILL BE MUCH OF A
DECREASE BELOW THAT PERHAPS DOWN TO 2500 FEET AT TIMES TODAY AND
AGAIN LATER OVERNIGHT AS ANOTHER DISTURBANCE MOVES ACROSS. /JBONK
&&
.MARINE...SEAS GENERALLY RUNNING 10 TO 12 FEET AT THIS HOUR ACROSS
ALL THE BUOYS THOUGH EXPECTED TO INCREASE SOMEWHAT TO AROUND 15 TO
17 FEET AS WIND AND RELATED WAVES INCREASE TODAY AND THEN AGAIN
LATER TONIGHT UNDER GALE CONDITIONS. MAIN THREAT APPEARS TO BE MAINLY
FROM GALE FORCE GUSTS TODAY WITH THE WARNING IN PLACE. PREVIOUS
SHIFTS HAD CONCERNS FOR A COASTAL JET DEVELOPING BUT LOOKING AT
THE INSTABILITY IN PLACE...UNSTABLE CONDITIONS DO NOT FAVOR THE
WINDS HUGGING THE TERRAIN SO WILL PULL BACK GUST WORDING. LATER
TONIGHT AND EARLY TOMORROW COULD SEE ANOTHER SURFACE LOW SWING
ACROSS THE WATERS BRINGING POTENTIAL FOR SUSTAINED GALES ACROSS
THE CENTRAL WATERS BUT STILL HAVE SIGNIFICANT CONSISTENCY ISSUES
AMONG MODELS. FOR NOW WILL EXERCISE CAUTION AND FOLLOW THE
STRONGER SOLUTION FROM THE NAM.
COASTAL RIVERS CONTINUE TO RECEDE AND WILL LIKELY LET THE COASTAL
FLOOD ADVISORY FOR TIDAL OVERFLOW TO EXPIRE AT 10 AM THIS
MORNING. /JBONK
