AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
320 PM PST WED DEC 19 2007
.SHORT TERM...TONIGHT THROUGH THURSDAY MORNING...HAVE ISSUED
NUMEROUS WINTER WEATHER HIGHLIGHTS FOR ALL INLAND AREAS. A
STRONG WET COLD FRONT WILL MOVE THROUGH THE AREA TONIGHT. THE
SYSTEM LOOKS SUBSTANTIALLY WETTER THAN IT DID 24 HOURS AGO AS
SATELLITE IMAGERY IS BRINGING A NICE 1.27 INCH PRECIPATABLE WATER
BAND WRAPED UP WITH THE FRONT. I HAVE MODIFIED SNOW AMOUNT
FORECASTS WHICH PROMPTED NUMEROUS WINTER WEATHER ADVISORIES AND
WARNINGS. EVENT SHOULD BE TOO QUICK MOVING TO GENERATE FLOOD
ISSUES.
THURSDAY AFTERNOON AND THURSDAY NIGHT...THE 500MB TROUGH AXIS WILL
SWING THROUGH WESTERN OREGON BY MID DAY THURSDAY WITH ACTION
BEHIND THIS FEATURE RAPIDLY CHANGING TO SHOWERS AND DECREASING
THROUGH FRIDAY MORNING.
&&
.LONG TERM...FRIDAY WILL BE THE BEST DAY FOR HOLIDAY TRAVEL AS A
HIGH PRESSURE RIDGE PROVIDES A BRIEF BREAK BETWEEN WEATHER
SYSTEMS. I HAVE ADDED MENTION OF AREAS OF MORNING VALLEY FOG BUT
OTHERWISE THERE WILL ONLY BE INCREASING HIGH CLOUDS LATE IN THE
DAY AHEAD OF THE NEXT FRONT.
STRENGTH IS STILL SOMEWHAT IN QUESTION...BUT THE ECMWF AND GFS ARE
IN AGREEMENT ON THE NEXT COLD FRONT REACHING THE COAST SATURDAY
MORNING AND MOVING INLAND DURING THE AFTERNOON AND EVENING WITH SNOW
LEVELS BETWEEN 4000 AND 4500 FEET. EXPECT SCATTERED TO NUMEROUS
SHOWERS BEHIND THE FRONT LATE SATURDAY NIGHT INTO EARLY SUNDAY WHILE
A WARM FRONT ASSOCIATED WITH THE NEXT STORM APPROACHES THE COAST.
THE GFS AND ECMWF BEGIN TO MORE NOTICEABLY DIVERGE SUNDAY NIGHT WITH
THE ECMWF ABOUT 6 HOURS SLOWER BUT ALSO COLDER AND STRONGER THAN THE
GFS IN REGARDS TO A COLD FRONT THAT WILL AFFECT THE AREA IN THE
SUNDAY NIGHT/MONDAY MORNING PERIOD.
ANOTHER BREAK BETWEEN SYSTEMS IS LIKELY MONDAY NIGHT INTO CHRISTMAS
DAY...WHICH WOULD LIKELY PRODUCE ANOTHER BATCH OF LATE NIGHT AND
MORNING VALLEY FOG.
THE NEXT FRONT COULD ARRIVE TO THE COAST AS SOON AS TUESDAY
AFTERNOON WITH WET CONDITIONS LIKELY INLAND BY AROUND MIDNIGHT. BOTH
THE ECMWF AND GFS SHOW WET CONDITIONS LATE TUESDAY NIGHT INTO
WEDNESDAY WITH THE MODELS AGAIN SHOWING THE SAME TREND...THE ECMWF
SLOWER...STRONGER AND WETTER THAN THE GFS. FOR NOW...CHANCE POPS
WILL SUFFICE FOR WEDNESDAY WITH BOTH MODELS SHOWING POST FRONTAL
SHOWERS DESPITE A MAJOR DIFFERENCE IN POSITIONING OF THE UPPER LEVEL
TROUGH.
&&
.AVIATION...WIDESPREAD MVFR CONDITIONS WILL BECOME WIDESPREAD IFR
AS A STRONG PACIFIC COLD FRONT MOVES INTO THE AREA. THE FREEZING
LEVEL WILL FALL RAPIDLY TONIGHT. PLEASE CHECK FOR AIRMETS AND
SIGMENTS OVER THE REGION.
