AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
336 AM PST MON JAN 17 2011

.DISCUSSION...A CHANCE OF LIGHT SHOWERS WILL LINGER IN SOUTHWEST
OREGON TODAY...WITH THE HIGHEST PROBABILITY FOR DRIZZLE-LY SHOWERS IN
VALLEYS THIS MORNING AS A WEAK SHORTWAVE MOVES EAST ACROSS
NORTHERN OREGON. THE EFFECTS OF THE HEAVY RAIN YESTERDAY HAVE BEEN
MINIMAL AND ALL RIVER FORECAST POINTS ARE EXPECTED TO REMAIN BELOW
FLOOD STAGE. BUT THE IMPACTS ARE NOT QUITE OVER AS FLOWS WILL BE PEAKING
AT MANY DOWNSTREAM LOCATIONS DURING THE DAY TODAY. ANOTHER
LINGERING IMPACT IS STRONG SOUTHWEST WINDS IN NORTHERN LAKE COUNTY
THAT WILL CONTINUE UNTIL AROUND 10 AM.

A LONGWAVE RIDGE IS EXPECTED TO REMAIN ANCHORED FROM THE EASTERN
PACIFIC INTO CALIFORNIA OVER THE NEXT WEEK TO TEN DAYS WHILE A
SERIES OF RELATIVELY WEAK DISTURBANCES MOVE EAST OVER THE TOP OF
THE RIDGE INTO THE PACIFIC NORTHWEST. THIS WILL RESULT IN NIGHT
AND MORNING VALLEY FOG AND ALSO TEMPERATURES COOLING BACK CLOSER
TO NORMAL VALUES.

AFTER THE VERY WEAK SHORTWAVE TROUGH TODAY...THE NEXT FRONTAL
SYSTEM WILL MOVE SOUTHEAST FROM VANCOUVER ISLAND ACROSS WASHINGTON
INTO EASTERN OREGON ON TUESDAY INTO TUESDAY NIGHT. THIS WILL BE
STRONG ENOUGH FOR A SLIGHT CHANCE TO CHANCE OF RAIN AND MOUNTAIN
SNOW WITH SNOW LEVELS FALLING TO AROUND 5000 FEET BY TUESDAY
EVENING THEN TO 3500 FEET BY EARLY WEDNESDAY. THE SOUTHERN OREGON
CASCADES MAY RECEIVE AN INCH OR SO OF SNOW.

WEDNESDAY LOOKS TO BE THE COLDEST DAY OF THE WEEK WITH NORTHERLY
WINDS ALOFT AS THE TROUGH DROPS INTO UTAH AND HIGH PRESSURE BUILDS
FAR OFFSHORE. THE RIDGE WILL SLOWLY BUILD EAST FROM WEDNESDAY
INTO FRIDAY WITH A PERIOD OF DRY CONDITIONS AND VALLEY FOG THAT
MAY PERSIST INTO THE AFTERNOON HOURS.

THE TIMING IS STILL UNCERTAIN AS IT RELATES TO THE NEXT WEATHER
SYSTEM TOWARD THE END OF THE WEEK. THE 00Z GFS INDICATES IT WILL
ARRIVE AT THE COAST LATE FRIDAY AFTERNOON AND MOVE SOUTHEAST
ACROSS OUR REGION THROUGH EARLY SATURDAY WHILE THE ECMWF TIMING
IS FROM SATURDAY AFTERNOON THROUGH SATURDAY NIGHT. IT IS LIKELY
TO BE STRONGER THAN THE TUESDAY SYSTEM BUT BEAR A MUCH CLOSER
RESEMBLANCE TO THAT TROUGH THAN THE ONE FROM YESTERDAY. BOTH
MODELS HAVE THE PACIFIC RIDGE REBUILDING EARLY NEXT WEEK.

&&

.AVIATION...WESTERLY WINDS ALOFT ARE VERY STRONG OVER LAKE COUNTY
THIS MORNING. IFR WITH LOW CLOUDS AND FOG IN VALLEYS THIS
MORNING...OTHERWISE SKIES ARE MAINLY VFR WITH LINGERING LOCAL MVFR
AND MOUNTAIN OBSCURATIONS. CONDITIONS WILL IMPROVE TO VFR THIS
AFTERNOON BUT VALLEY IFR WILL DEVELOP AGAIN LATE THIS EVENING.
