AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE MEDFORD OR
901 PM PST MON DEC 28 2009

.DISCUSSION...FIRST THING...ADDED DENSE FOG ADVISORY FOR SOUTHWEST
OREGON.  DENSE FREEZING FOG IN ROGUE AND ILLINOIS VALLEYS IS
ALLOWING FOR ICE TO GLAZE SURFACES...SO DRIVERS AND PEDESTRIANS
SHOULD BE CAUTIOUS THROUGH TUESDAY MORNING. WARMER TEMPERATURES
ARE PREVENTING ANY WIDESPREAD AREAS OF FREEZING FOG IN THE UMPQUA
BASIN...BUT VISIBILITY IS POOR IN THAT REGION AS WELL. FORECAST
AND HEADLINES LOOK TO BE ON TRACK AS MODELS HAVE TRENDED A BIT
WEAKER IN RECENT RUNS FOR THE MODERATELY STRONG COLD FRONT THAT
WILL ARRIVE TUESDAY. MODEL SOLUTIONS FOR THE LOW PRESSURE CENTER
HAVE RISEN ABOUT 5MB RECENTLY...AND HAVE BEGUN TO SWING LOW CENTER
FURTHER AWAY FROM THE COAST. THE TREND FOR WEAKENING STORMS HAS
BEEN A TREND IN ITSELF SO FAR THIS WET SEASON. THUS...WINDS WILL
NOT BE WARNING- LEVEL AT THE COAST BUT STILL STRONG AT 20 TO 35
MPH WITH GUSTS TO 50 MPH. OTHER AREAS LOOKED AT THIS EVENING WERE
SHASTA VALLEY WIND POTENTIAL...EAST SIDE WINDS...AND MOUNTAIN
SNOWS. RDD- MFR PRESSURE GRADIENT REACHES ABOUT 5MB BUT H7 WIND
DIRECTION IS BASICALLY WEST...SO THIS WILL LIKELY PREVENT ANY
ADVISORY WINDS REACHING SHASTA VALLEY BUT GUSTS TO 40 MPH WILL
OCCUR TUESDAY EVENING. UPPER AND LOWER WIND FLOW EAST OF THE
CASCADES ARE SIMILARLY DISCONNECTED...RESULTING IN GUSTS TO 45 MPH
IN HIGHEST TERRAIN OF LAKE...MODOC...AND KLAMATH COUNTIES. BUT
OVERALL LOWER ELEVATION WINDS IN THIS REGION SHOULD REMAIN
SUSTAINED AT 15 TO 25 MPH WITH HIGHER GUSTS ON TUESDAY EVENING.
GIVEN DISTANCE TO PARENT LOW...SOUTHERLY FLOW...AND LOW TO
MODERATE AMOUNT OF MOISTURE AVAILABLE...SNOW AMOUNTS WILL BE
HIGHEST NEAR MOUNT SHASTA BEGINNING TUESDAY AFTERNOON. CASCADES
WILL ALSO BE IMPACTED WITH SNOW ABOVE 3000 FEET...AND WINTER
WEATHER ADVISORY COVERS THESE TWO REGIONS WELL. EAST SIDE AREAS
WILL LIKELY NOT SEE A BIG SNOWFALL WITH THIS SYSTEM GIVEN LACK OF
ANY EASTERLY COMPONENT TO WINDS...AND THE AFOREMENTIONED MARGINAL
DEEP MOISTURE. LIQUID EQUIVALENT PRECIPITATION AT LMT IS BETWEEN
0.25 AND 0.5 INCHES...SO NEARING ADVISORY CRITERIA. MIDSHIFT WILL
DETERMINE WHETHER ADVISORY IS NECESSARY AS IT LIKELY WILL BE
BORDERLINE TUESDAY EVENING THROUGH WEDNESDAY MORNING. NEXT SYSTEM
ON THURSDAY IS SIGNIFICANTLY WARMER WITH A MORE POTENT PLUME OF
MOISTURE AS NAM IS SUGGESTING PWAT VALUES 2 STANDARD DEVIATIONS
ABOVE NORMAL. MFR-RDD PRESSURE GRADIENT JUMPS TO 7MB...SO WIND
HEADLINES WILL LIKELY BE NECESSARY AFTER THE TUESDAY STORM WINDS
DOWN...AND A FEW MORE MODEL RUNS COME IN.

&&

.AVIATION...DENSE FOG AND FREEZING FOG IN ROGUE AND UMPQUA BASIN
WILL IMPACT TERMINALS THERE THROUGH TUESDAY MORNING. FLYING
CONDITIONS OVERALL...DESPITE THE FOG LIFTING...WILL DEGRADE
TUESDAY WITH THE APPROACH OF A COLD FRONT. MODERATELY STRONG FRONT
WILL IMPACT COASTAL TERMINALS WITH LOW LEVEL WIND SHEAR BY TUESDAY
AFTERNOON...AND BRING MVFR CLOUDS TO MOST OF THE REGION BY
AFTERNOON AND EVENING. SNOW WILL IMPACT TERMINALS EAST OF THE
CASCADES BY TUESDAY EVENING WITH REDUCED VISIBILITY. MOUNTAIN
OBSCURATION WILL AFFECT THE ENTIRE AREA...ESPECIALLY ALONG AND
WEST OF THE CASCADES...AFTER 21Z.

&&
NK

.PREV DISCUSSION... /ISSUED 343 PM PST MON DEC 28 2009/

DISCUSSION...COVERAGE OF VALLEY FOG WILL INCREASE ON THE WEST
SIDE AGAIN THIS EVENING AND LOCALLY DEVELOP NEAR KLAMATH FALLS
ALSO.

IT IS NOT THE ONLY ITEM OF INTEREST BUT THE FIRST CONCERN IS THE
IMPACTS FROM A MODERATELY STRONG COLD FRONT THAT WILL MOVE EAST
ACROSS OUR REGION LATE TUESDAY MORNING THROUGH TUESDAY NIGHT. THE
HIGH WIND WATCH FOR THE COASTAL ZONES WAS CANCELLED WITH SOUTH
WINDS EXPECTED TO NOT QUITE REACH WARNING CRITERIA. GUSTS OF 55 TO
70 MPH ARE POSSIBLE AT HEADLANDS BETWEEN 9AM AND 3PM TUESDAY BUT
OTHERWISE WINDS ARE FORECAST AT 20 TO 35 MPH WITH GUSTS TO 50 MPH.
ALSO...IT WILL BE WINDY AT HIGHER ELEVATIONS INLAND AND BREEZY
SOUTH WINDS WILL DEVELOP IN THE SHASTA VALLEY.

SNOW LEVELS WILL BEGIN NEAR 4000 FEET TUESDAY AND FALL TO 3000
FEET OVERNIGHT. THE WINTER STORM WATCH HAS BEEN UPGRADED TO A
WINTER WEATHER ADVISORY FOR SNOW FOR MUCH OF SISKIYOU COUNTY AND
AN ADVISORY ALSO ISSUED FOR THE SOUTHERN OREGON CASCADES AND SISKIYOUS.
SOUTHERLY WINDS WILL INITIALLY FAVOR SNOWFALL NEAR MOUNT SHASTA IN
THE AFTERNOON AND EARLY EVENING...THEN BEHIND THE FRONT SNOW
SHOWERS IN WESTERLY FLOW WILL BE FAVORED IN THE CASCADES NEAR
CRATER LAKE. SNOW SHOWERS WILL TAPER OFF EARLY WEDNESDAY
MORNING...EXCEPT LINGERING UNTIL LATE MORNING NEAR CRATER LAKE.

SHOWERS WILL BE FEW AND FAR BETWEEN WEDNESDAY AFTERNOON BUT A WARM
FRONT WILL BE APPROACHING THE COAST FROM THE SOUTHWEST. THIS FRONT
MAY BRING MODERATE TO HEAVY RAIN TO THE COAST LATE WEDNESDAY NIGHT
..CONTINUING AND SPREADING INLAND THURSDAY WITH A STRONG TRAILING
COLD FRONT THURSDAY NIGHT INTO FRIDAY. SNOW LEVELS LOOK TO BE
HIGHER WITH THIS STRONGER STORM...ABOVE 5000 FEET DURING THE
MAJORITY OF THE EVENT. THE GFS AND ECMWF DO HAVE IMPORTANT
DIFFERENCES IN THE DETAILS OF POSITION AND STRENGTH OF THIS
SYSTEM. THE 18Z GFS HAS JUST ARRIVED AND COMPARED TOWARD ITS 12Z
SOLUTION...IT DOES TREND TOWARD THE STRONGER ECMWF SOLUTION. THIS
HAS THE POTENTIAL TO BE THE BIGGEST PRECIPITATION PRODUCER SO FAR
OF WHAT HAS HERETOFORE BEEN A BELOW NORMAL FALL AND WINTER SEASON
OF PRECIP.

AN UPPER LOW IS FORECAST TO MOVE INTO SOUTHERN CANADA FRIDAY WITH
ANOTHER WEAKER COLD FRONT MOVING THROUGH OUR REGION. BEYOND
FRIDAY...MODEL DIFFERENCES BECOME SIGNIFICANT BUT A SERIES OF SYSTEMS
WILL CONTINUE THROUGH EARLY NEXT WEEK.
