AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
800 PM PST FRI NOV 30 2012
.DISCUSSION...01/00Z NAM IN. 01/00Z GFS IN THROUGH 72HR.
THERE ARE CURRENTLY SOME SCATTERED SHOWERS AND GUSTY WINDS OVER
THE MEDFORD CWA...BUT NOTHING LIKE WHAT OCCURRED YESTERDAY. THE
CURRENT CONCERN IS A LINE OF THUNDERSTORMS APPROACHING THE COASTAL
MARINE WATERS...AND A SPECIAL MARINE WARNING IS IN EFFECT FOR
THAT.
AN UPPER TROUGH REMAINS OFFSHORE AND SHORT WAVES EJECTING FROM THE
TROUGH WILL CONTINUE TO MOVE THROUGH THE PACIFIC NORTHWEST. THE
NEXT WAVE ON THE AGENDA WILL MOVE ONSHORE LATER TONIGHT...FOLLOWED
BY A STRONGER ONE LATE SATURDAY NIGHT INTO SUNDAY MORNING.
EXPECT ANOTHER ROUND OF STEADY PRECIPITATION TO HIT THE COAST
LATER TONIGHT. GENERALLY 2 TO 4 INCHES FOR CURRY/JOSEPHINE/SISKIYOU
COUNTIES...1 TO 2 INCHES FOR OTHER WESTSIDE LOCATIONS AND LESS
THAN AN INCH EAST OF THE CASCADES. THIS WILL EXACERBATE THE
FLOODING ALONG THE COQUILLE RIVER. HOWEVER...FEW FLOODING RELATED
PROBLEMS ARE ANTICIPATED INLAND.
STRONG SOUTH WINDS ARE DEVELOPING ALONG THE COAST BUT THEY SHOULD
STAY BELOW THE HIGH WIND WARNING CRITERIA. GUSTY WINDS WILL SPREAD
INLAND AS WELL...AND WIND ADVISORIES ARE IN EFFECT FOR MOST OF THE
EAST SIDE AND THE SHASTA VALLEY TONIGHT.
THE STRONGER SHORT WAVE WILL PUSH A WINDIER AND WETTER FRONT
ONSHORE SATURDAY NIGHT. HIGH WIND WATCHES ARE IN EFFECT FOR THE
COAST...EAST SIDE...AND SHASTA VALLEY WITH THIS SYSTEM. THE COAST
AND COAST RANGE WILL GET ANOTHER SHOT OF SIGNIFICANT RAIN.
HOWEVER...THE WETTEST AREA WILL BE NORTHERN CALIFORNIA...
ESPECIALLY THE NORTHERN RIM OF THE SACRAMENTO VALLEY...WHERE IT
WILL BE AIDED BY SOUTHERLY UPSLOPE WINDS. FLOOD WATCHES ARE
CURRENTLY IN EFFECT FOR THIS STORM.
ONE MORE WEAK WAVE WILL MOVE THROUGH SUNDAY AFTERNOON...THEN THERE
WILL BE A SHORT BREAK IN THE ACTION AS A WEAK RIDGE BUILDS IN
FROM THE SOUTH SUNDAY INTO MONDAY. THERE WILL STILL BE SHOWERS
AROUND...BUT AMOUNTS WILL BE LIGHT.
EXTENDED DISCUSSION FROM THE FRIDAY AFTERNOON AFD...MONDAY NIGHT
THROUGH THURSDAY. THE NEXT SYSTEM ON MONDAY NIGHT INTO TUESDAY HAS
POTENTIAL TO BE VERY WET OVER A WIDE AREA. IT HAS VERY DEEP
MOISTURE ORIGINATING FROM NEAR HAWAII. IT WON'T HAVE THE JET
SUPPORT OF THE SUNDAY SYSTEM. THE FRONT WILL ALSO MOVE SLOWER SO
RAINFALL DURATIONS WILL INCREASE. ISENTROPIC ANALYSIS SHOWS AN
EXTENDED PERIOD OF MODERATE LIFT FOCUSED ON THE SOUTH COAST AND NW
CALIFORNIA. POTENTIAL RAINFALL WITH THIS SYSTEM IS 5 TO 7 INCHES
IN THE FAVORED CURRY/JOSEPHINE/SISKIYOU COUNTY AREA.
ONCE THIS SYSTEM CLEARS THE AREA WE APPEAR TO HAVE A DRY PERIOD
WITH UPPER LEVEL HIGH PRESSURE. JBL
&&
.AVIATION...ANOTHER COLD FRONT WILL MOVE ONSHORE TONIGHT BRINGING
MVFR/LOCAL IFR CIGS ALONG WITH GUSTY WINDS AND -RA/RA TO MOST
AREAS. STRONGEST WINDS WILL BE ALONG THE COAST AND ALSO THE EAST
SIDE WHERE GUSTS TO 35 KT ARE POSSIBLE WITH LIGHT TO MODERATE
TURBULENCE. THERE IS A RISK OF LOW-LEVEL WIND SHEAR ALONG THE
COAST AND PERHAPS JUST INLAND THIS EVENING BEFORE THE FRONT MOVES
IN. EXPECT WIDESPREAD MOUNTAIN OBSCURATIONS TONIGHT INTO SATURDAY
MORNING. SPILDE
