AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
238 AM PST MON DEC 12 2011

.DISCUSSION...A COLD FRONT HAS MOVED THROUGH THE ENTIRE FORECAST
AREA THIS MORNING AND THE AIRMASS HAS COOLED SIGNFICANTLY THROUGH
THE MID LEVELS. UNFORTUNATELY, IT WAS NOT STRONG ENOUGH TO SCOUR
OUT THE INVERSIONS. SFC LOW PRESSURE REMAINS OVER THE EAST SIDE
AND THE RESULTING GRADIENT IS KEEPING FIARLY BREEZY WINDS GOING,
AT LEAST OVER LAKE COUNTY. THE MODELS CONTINUE TO SHOW A LITTLE
LIGHT SNOW OVER LAKE COUNTY THIS MORNING, AND WHILE NONE OF THE
OBS HAVE REPORTED ANY YET, IR CLOUD ENHANCEMENT OVER THE AREA
LENDS SOME CREDIBILITY TO THE IDEA. DON'T THINK IT WILL AMOUNT TO
MUCH, BUT HAVE PAINTED IN SOME ISOLATED SNOW SHOWERS. THE COAST
REMAINS MOSTLY CLEAR AND COLD THIS MORNING. NORTH BEND HAS SO FAR
DIPPED TO 28. WINDS HAVE KEPT TEMPS UP OVER CURRY COUNTY RIGHT AT
THE COAST, BUT INLAND AREAS ARE CERTAINLY COLDER. IN HINDSIGHT, A
FREEZE WARNING WOULD HAVE BEEN MORE APPROPRIATE AT LEAST FOR COOS
COUNTY, BUT WILL LET THE FROST ADVISORY CONTINUE THROUGH 8AM.

STRATUS IS ONCE AGAIN PRESENT ON THE WEST SIDE, BUT AS OPPOSED TO
MANY RECENT MORNINGS, IT IS HIGHER AND INHIBITING FOG FORMATION IN
MOST PLACES. WEBCAMS DO SHOW FOG AROUND GRANTS PASS AND ROSEBURG,
BUT IT IS MUCH LESS WIDESPREAD THIS MORNING. THERE IS ALSO A
LITTLE FOG ALONG BEAR CREEK AROUND MEDFORD AND THE ROGUE RIVER
ALONG THE INTERSTATE. THINK THIS STRATUS DECK WILL CONTINUE TO
INHIBIT FOG FORMATION FOR MOST LOCALES, AND IF THIS IS RIGHT, THEN
SKIES WILL BE QUICKER TO CLEAR TODAY. THIS WILL LEAD TO A LITTLE
WARMER TEMPERATURES THROUGH THE ROGUE VALLEY THAN WE'VE SEEN.
PLACES LIKE GRANTS PASS MAY STAY LOCKED IN, BUT THINK THERE IS A
FAIR CHANCE OF A WIDESPREAD BREAKOUT TODAY. EVEN SO, FLOW REMAINS
WEAK AND INVERSIONS STRONG, SO WILL KEEP THE AIR STAGNATION
ADIVSORY IN PLACE ON THE WEST SIDE. AM NOT AS SURE ABOUT THE
ADVISORY ON THE EAST SIDE THOUGH. IT IS REMAINING PRETTY WELL
MIXED WITH A DECENT SURFACE GRADIENT DRIVEN WIND FIELD. HOWEVER,
THE LATEST AIR QUALITY DATA REMAINS DEGRADED ON THE EAST SIDE AS
WELL, SO WILL KEEP IT GOING FOR NOW AND DAY SHIFT CAN RE-EVALUATE.

EITHER WAY, THE MID LEVELS WARM AND INVERSIONS STRENGTHEN AGAIN
TONIGHT THROUGH WED MORNING AS WEAK RIDGING ALOFT MOVES OVERHEAD.
THIS PERIOD WILL BE DRY, BUT STRATUS AND FOG WILL ONCE AGAIN BE
PERSISTENT IN THE VALLEYS. AM EXPECTING AT LEAST ONE MORE MOSTLY
CLEAR AND COLD NIGHT TONIGHT ALONG THE COAST, SO WENT AHEAD WITH
ANOTHER FROST AVISORY AND FREEZE WARNING. A STRONG SYSTEM IS STILL
ON TAP FOR WEDNESDAY NIGHT AND THURSDAY. UNFORTUNATELY, THE MODELS
ARE NOT IN AS GOOD OF AGREEMENT AS THEY WERE. THE NAM AND EC NOW
SHOW THE SYSTEM AND THE BULK OF ITS PRECIP A LITTLE FURTHER NORTH,
WHEREAS THE GFS AND GEM CONTINUE TO SHOW A MORE SOUTHERLY ROUTE
AND MORE PRECIP FOR SW OREGON AND NORTHERN CALIFORNIA. DID
CONTINUE THE UPWARD TREND OF POPS, BUT DIDN'T MAKE ANY OTHER
CHANGES. AT THE VERY LEAST IT IS RELATIVELY CERTAIN THAT THIS
SYSTEM WILL BE STRONG ENOUGH TO MIX OUT THE INVERSIONS. -WRIGHT

&&

.AVIATION...MOSTLY VFR OVER THE MEDFORD FA THIS MORNING. STRATUS
IS CREATING AREAS OF MVFR CIGS WITH ISOLD POCKETS OF IFR CIGS AND
VIS IN FG. THINK THIS WILL CONTINUE TO BE THE CASE THROUGH DAWN
WITH THE BEST CHANCE OF IFR CIGS/VIS AT THE TERMINALS BEING
BETWEEN 12Z AND 17Z. STRATUS WILL BREAK UP AFTER 18Z WITH
WIDESPREAD VFR EXPECTED THROUGH THE EVENING.
