AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
249 AM PST FRI DEC 9 2011

.DISCUSSION...A STAGNANT PATTERN CONTINUES OVER THE PACNW THIS
MORNING AS HIGH PRESSURE ALOFT REMAINS PARKED JUST OFF THE NW
OREGON COAST. THE THERMAL SURFACE TROUGH AXIS STRADDLES THE COAST,
BUT IT IS BEGINNING TO CREEP NORTHWARD. MORNING 11-3.9 SATELLITE
IMAGERY SHOWS STRATUS AND FOG COVERAGE SIMILAR TO YESTERDAY...THAT
IS WIDESPREAD COVERAGE IN THE UMPQUA AND MORE SCATTERED COVERAGE
OVER JOSEPHINE COUNTY. WE ARE SEEING SOME LOWER VISIBILITIES
DEVELOPING OVER PORTIONS OF THE COAST AND JACKSON COUNTY
(INCLUDING THE ROGUE VALLEY) WHICH WILL LIKELY FILL IN MORE
EXTENSIVELY BY DAWN. ALSO OF NOTE IS A FINGER OF MARINE STRATUS
MOVING NORTH ALONG THE CALIFORNIA COAST. THIS IS DUE TO INCREASING
SOUTHERLY FLOW ALONG THE COAST AS THE AFOREMENTIONED SURFACE LOW
MOVES NORTH.

THE RIDGE IS EXPECTED TO REMAIN UNCHANGED MUCH OF TODAY THUS TODAY
WILL BE A NEAR CARBON COPY OF YESTERDAY. ONE NOTEABLE EXCEPTION
WILL BE ALONG THE SOUTHERN CURRY COAST AROUND BROOKINGS WHERE THE
OFFSHORE FLOW WILL BECOME SOUTHERLY, ALLOWING STRATUS TO MOVE IN
THIS MORNING. THIS WILL PREVENT THE AREA FROM GETTING NEARLY AS
WARM AS YESTERDAY.

BY TONIGHT, HOWEVER, THE RIDGE WILL FINALLY BEGINS TO WEAKEN AND
MOVE EAST AS A TROUGH OUT AROUND 150W MOVES IN. THIS WILL ALSO
CAUSE THE THERMAL SURFACE TROUGH TO WEAKEN AND MOVE NORTH. THE
RESULTING SOUTHERLY, ONSHORE FLOW ALONG THE COAST ALMOST ALWAYS
RESULTS IN A SURGE OF STRATUS ALONG THE COAST. HAVE THUS INCREASED
STRATUS ALONG THE COAST AND OVER THE WATERS TONIGHT INTO SATURDAY
MORNING. THINK WE'LL GET ONE MORE COLD NIGHT ALONG THE COAST
FRIDAY NIGHT/SATURDAY AM BEFORE THE STRATUS MOVES IN AND HAVE
UPGRADED THE FREEZE WATCH ALONG THE COAST TO A WARNING AND ISSUED
FROST ADVISORIES AS WELL.

THE UPPER TROUGH AND ASSOCIATED SURFACE FRONT WILL THEN
MOVE INTO THE COAST SATURDAY NIGHT AND SUNDAY. FLOW AHEAD OF THE
FRONT AND CERTAINLY WITH THE FRONT WILL FINALLY MIX OUT THE
INVERSIONS AND CLEAR THE AIR IN THE VALLEYS. THE AIR STAGNATION
ADIVSORY CURRENTLY GOES THROUGH NOON SATURDAY AND WILL KEEP IT AS
IS FOR NOW. MOST OF THE DYNAMICS WITH THIS FRONT WILL MOVE IN
SOUTH OF US AS THE SYSTEM CLOSES OFF OVER CALIFORNIA. AS A RESULT,
THIS ONE WON'T BE MUCH OF A PRECIP PRODUCER FOR US, BUT IT WILL
PROVIDE OUR BEST SHOT AT PRECIP IN QUITE A WHILE.

THERE HASN'T BEEN MUCH CHANGE IN THE EXTENDED FORECAST PERIOD
EITHER. MODELS ALL SHOW ANOTHER SYSTEM ARRIVING MID WEEK, BUT
DIFFER DRAMATICALLY IN THE DETAILS. HOWEVER, IT FINALLY LOOKS LIKE
WE WILL GET OUT OF THE STAGNANT PATTERN AND STAY OUT. -WRIGHT
