AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
916 PM PST MON DEC 6 2010

.DISCUSSION...MADE SOME UPDATES TO THE FORECAST THIS EVENING. RAIN
HAS BEEN FALLING ACROSS THE COAST AND TWO SHORT WAVES ARE SEEN IN
IR SATELLITE THAT WILL ALLOW CHANCES TO INCREASE THROUGH THE
REMAINDER OF THE NIGHT. THE FIRST WAVE IS MOVING INLAND ACROSS THE
COAST RIGHT NOW AND ANOTHER WILL MOVE ACROSS AFTER MIDNIGHT.
HIGHER POPS WERE NEEDED CONSIDERING THE COMBINATION OF THE TWO
WAVES AND CONSIDERING CURRENT OBSERVED PRECIPITATION.

SOUTH WINDS WILL BE INCREASING OVER THE REGION THROUGH TUESDAY
NIGHT. HAVE UPGRADED THE CURRENT HIGH WIND WATCH FOR THE COAST TO
A WARNING AND BUMPED UP THE START TIME TO 1 PM TUESDAY. AS FOR THE
INLAND WATCHES...FEEL THE CHANCES FOR ADVISORY CONDITIONS ACROSS
THE ROGUE...SHASTA VALLEY...AND SUMMER LAKE AREAS IS HIGH. HAVE
OPTED TO ALLOW SOME MORE TIME ON THE WATCH AND CURRENT NIGHT
SHIFT IS GOING TO MAKE A DECISION ON ANY NECESSARY WARNINGS.

&&

.MARINE...INCREASING WINDS AND SEAS ARE ON TAP THROUGH TUESDAY
NIGHT AS PRESSURE GRADIENTS INCREASE IN RESPONSE TO A STRONG LOW
MOVING THROUGH THE GULF OF ALASKA. HAVE UPGRADED THE GALE AND
HAZARDOUS SEAS WATCHES FOR THE INNER WATERS TO WARNINGS.

&&

.AVIATION...WITH THE EXCEPTION OF MOUNT SHASTA CITY...VFR
CONDITIONS CONTINUE THROUGH THIS EVENING FOR ALL TERMINALS. AN
OCCLUDED FRONT MOVES INTO SOUTHWEST OREGON TONIGHT RESULTING IN
LOWERING CIGS ALONG THE COAST. INLAND CIGS WILL LOWER...BUT SHOULD
REMAIN VFR WITH LOCAL MVFR. THE MAIN CONCERN TONIGHT INTO TUESDAY
WILL BE THE POTENTIAL FOR WIND SPEED SHEAR AT THE COAST AND
POSSIBLY INTO THE UMPQUA BASIN.

&&

.PREV DISCUSSION... /ISSUED 211 PM PST MON DEC 6 2010/

DISCUSSION...CURRENT SATELLITE IMAGE SHOWS A STRONG UPPER LOW OUT
NEAR 45 N AND 149 W. AHEAD OF THE LOW IS A STRONG COLD FRONT WHICH
WILL BRING INCREASING WINDS OVER THE MARINE WATERS TONIGHT...THEN
ALONG THE COAST TUESDAY MORNING. PRIOR TO THAT...AN OCCLUDED FRONT
MOVES THROUGH THE AREA TONIGHT AND WILL BRING RAIN MAINLY TO THE
COAST RANGE. SOME LIGHT RAIN COULD MAKE IT INTO THE UMPQUA BASIN AND
CASCADES...BUT ANYTHING WOULD BE LIGHT.

THE MAIN IMPACT ON TUESDAY WILL BE GUSTY WINDS ALONG THE COAST AND
SHASTA VALLEY. AS THE COLD FRONT SLOWLY INCHES TOWARDS THE COAST.
THE MODELS SUGGEST WINDS COULD GET CLOSE TO WARNING CRITERIA AT THE
COAST...BUT THE WIND DIRECTION BETWEEN 925 AND 850 MB SUGGEST THE
STRONGEST WINDS SHOULD BE BETWEEN GOLD BEACH AND CAPE BLANCO.
PRECIPITATION TUESDAY SHOULD REMAIN MAINLY OFFSHORE UNTIL THE FRONT
MOVES INLAND TUESDAY NIGHT.

AS PREVIOUSLY MENTIONED...THE FRONT MOVES INLAND TUESDAY NIGHT AND
WILL BRING INCREASING PRECIPITATION...MAINLY ALONG AND WEST OF THE
CASCADES DUE TO A MOIST WESTERLY FLOW ALOFT. THE WIND IMPACT THEN
SHIFTS EAST OF THE CASCADES EFFECTING MOSTLY LAKE COUNTY. HOWEVER
THE MODEL SOUNDINGS SAMPLED EAST OF THE CASCADES SUGGEST THERE MAY
BE ENOUGH OF AN INVERSION TO PREVENT THE STRONGER WINDS FROM MIXING
DOWN AT THE SURFACE. SO IT MAY BE THAT THE STRONGEST WINDS WILL BE
OVER THE HIGHER TERRAIN.

THE FRONT WILL STALL AND WEAKEN DURING THE DAY WEDNESDAY. AT THE
SAME TIME 500 MB HEIGHTS WILL INCREASE WHICH WILL RESULT IN SHOWERS
DECREASING IN THE AFTERNOON.

WEAK LOW PRESSURE FORMS ALONG A FRONTAL BOUNDARY THURSDAY AFTERNOON
BRINGING INCREASING PRECIPITATION TO SOUTHWEST OREGON.

REGARDING SNOW LEVELS....THEY ARE EXPECTED TO REMAIN HIGH ENOUGH
WHERE MAJOR ROADWAYS WILL NO BE IMPACTED. HOWEVER IT WILL WARRANT
CLOSE WATCHING OVERNIGHT TUESDAY INTO WEDNESDAY MORNING NEAR THE
MOUNT SHASTA REGION.    PETRUCELLI

LONG TERM...THE GFS AND ECMWF FORECAST A FLAT RIDGE OVER THE REGION
EARLY ON IN THE EXTENDED PERIOD...THEN THE RIDGE AMPLIFIES SOMEWHAT
OVER THE WEEKEND. THE MOIST SOUTHWEST FLOW FROM OFF THE EAST PACIFIC
WILL BE DIRECTED FURTHER TO OUR NORTH. BY LATER MONDAY BOTH MODELS
SHIFT THE RIDGE EAST TO OVER THE GREAT BASIN. THIS WILL ALLOW AN
OFFSHORE COLD FRONT TO MOVE CLOSER TO THE COAST WITH AN INCREASING
THREAT OF RAIN BY WEDNESDAY.    HOLTZ
