AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
801 PM PST WED DEC 19 2007
.DISCUSSION...00Z NGM/NAM IN. 00Z GFS IN THROUGH 12HR.
A STRONG WET COLD FRONT IS NOW MOVING THROUGH MOVE THROUGH THE
MEDFORD CWA. THIS SYSTEM IS SUBSTANTIALLY WETTER THAN IT WAS 24
HOURS AGO...SATELLITE IMAGERY SHOWS AN AREA OF 1.0-1.2 INCH
PRECIPITABLE WATER MOVING IN WITH THE FRONT. WHILE THE STEADY
PRECIPITATION WILL CHANGE TO SHOWERS BEHIND THE FRONT...NUMEROUS
SHOWERS WILL PERSIST INTO THURSDAY MORNING. AMENDED THE ZONES
EARLIER TONIGHT TO ADJUST TONIGHTS SNOW LEVELS DOWNWARD.
WINTER STORM WARNINGS AND SNOW ADVISORIES COVER MOST OF THE CWA.
THE WARNINGS ARE EFFECTIVE FROM NOW THROUGH 9-10AM THURSDAY...AND
THE ADVISORIES ARE NOW IN EFFECT UNTIL 10 AM THURSDAY.
THURSDAY AFTERNOON AND THURSDAY NIGHT...THE 500MB TROUGH AXIS WILL
MOVE THROUGH WESTERN OREGON BY NOON THURSDAY. SHOWERS WILL
DIMINISH AFTER THE TROUGH PASSES...AND WILL END BY FRIDAY MORNING.
LONG TERM DISCUSSION FROM THE AFTERNOON AFD...
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 NOTICABLY 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 THROUGH THE AREA. THE
FREEZING LEVEL WILL FALL RAPIDLY TONIGHT. PLEASE CHECK FOR AIRMETS
AND SIGMENTS OVER THE REGION. CONDITIONS WILL IMPROVE TO VFR
THURSDAY AFTERNOON WITH MVFR CIGS/VSBYS IN SHOWERS.
