AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
102 AM PST WED DEC 7 2011

.DISCUSSION...07/00Z NAM/GFS IN.

THE OMEGA BLOCK THAT BROUGHT THE STAGNANT AIR TO THE AREA IS
WEAKENING...BUT IT REMAINS IN PLACE AT THIS TIME.

THE INVERSION OVER THE VALLEY IS GRADUALLY WEAKENING AND THE AIR
MASS ALOFT CONTINUES TO BE VERY DRY. THIS IS ALLOWING THE LOW
CLOUDS AND FOG TO CLEAR OUT EARLIER AND REDEVELOP LATER...BUT
THERE WILL STILL BE PLENTY OF IT IN THE INTERIOR VALLEYS IN THE
LATE NIGHT AND EARLY MORNING HOURS.

THE WEATHER WEDNESDAY WILL BE MUCH LIKE THE WEATHER MONDAY AND
TUESDAY...MOSTLY CLEAR OVER THE RIDGES AND EAST SIDE WITH AREAS
OF LOW CLOUDS AND FOG IN THE VALLEYS WHICH WILL CLEAR IN THE
AFTERNOONS AND EVENINGS.

ANOTHER DISTURBANCE WILL MOVE THROUGH LATE WEDNESDAY NIGHT AND
THURSDAY MORNING. THE MODELS ARE TRENDING WEAKER WITH THIS FEATURE
AND IT IS LOOKING MORE AND MORE LIKE A NON-EVENT. MAY HAVE TO
EXTEND THE AIR STAGNATION ADVISORY FOR THE EAST SIDE.

THE PATTERN WILL FINALLY BECOME PROGRESSIVE AGAIN FRIDAY AND THE
OFFSHORE HIGH THAT HAS BEEN OUT THERE FOR THE PAST WEEK WILL
MOVE ONSHORE. IT WILL REMAIN DRY THROUGH AT LEAST SATURDAY
EVENING...AND THE SYSTEM MOVING IN SUNDAY LOOKS WEAK.

LONG TERM DISCUSSION FROM THE TUESDAY AFTERNOON AFD...SATURDAY
THROUGH TUESDAY. THE GFS IS NOW STARTING TO COME MORE IN LINE
WITH EC THIS WEEKEND INTO EARLY NEXT WEEK. BOTH SHOW A SHORTWAVE
TROUGH MOVING SOUTHEAST THROUGH WESTERN B.C. SATURDAY...THEN THE
EC DIGS THE TROUGH FARTHER WEST COMPARED TO THE GFS SUNDAY...BUT
NOT FAR ENOUGH TO TAP INTO ENOUGH MOISTURE FROM THE PACIFIC. THE
EC PAINTS SOME QPF...BUT SUSPECT ANY PRECIPITATION WILL BE
CONFINED TO THE NORTHERN CASCADES. EVEN THEN WE ARE EXPECTING ONLY
SLIGHT CHANCE POPS.

BOTH MODELS SUGGEST THE TROUGH CONTINUES TO DIG SOUTH INTO NORTHEAST
NEVADA MONDAY...THEN MOVES SLOWLY SOUTH TUESDAY. THE EC SHOWS A REX
BLOCK SETTING UP IN THE WAKE OF THE UPPER TROUGH TUESDAY WHILE THE
GFS SHOWS ANOTHER AND STRONGER TROUGH MOVING INTO THE PAC N.W. GIVEN
THE EC HAS BEEN THE MORE CONSISTENT OF THE TWO WE'LL CONTINUE TO
LEAN TOWARDS IT IN THE EXTENDED. THIS MEANS A CONTINUED PERIOD OF
DRY AND STABLE WEATHER WITH COLD NIGHTS AND COOL AFTERNOONS.

HPC IS GOING WITH A TRANSITION TO THE 00Z/06 EC ENSEMBLE SOLUTION
BEYOND DAY THREE WHICH SHOWS THE NORTHERN BRANCH REMAINING LOCKED
OVER THE EASTERN ONE THIRD OF THE U.S. WITH A RIDGE OVER THE WEST
DESPITE THE LARGER MODEL SPREAD. THIS GOES ALONG WITH THE THINKING
OF LEANING TOWARDS THE DRY SOLUTION THROUGH EARLY NEXT WEEK.

&&

.AVIATION...VFR AT ALL THE TERMINALS AT THIS TIMES...BUT SATELLITE
IMAGERY INDICATES THAT AREAS OF IFR CIGS/VSBYS ARE RETURNING TO
THE WEST SIDE VALLEYS AT THIS TIME. THE MOIST LAYER REMAINS SHALLOW
...SO THE FOG/LOW CLOUDS WILL BURN OFF BETWEEN 17-19Z WEDNESDAY
MORNING. VFR IS EXPECTED AGAIN FOR ALL LOCATIONS WEDNESDAY AFTERNOON.
AREAS OF IFR CIGS/VSBYS WILL RETURN TO THE WEST SIDE VALLEYS LATE
WEDNESDAY NIGHT.
