AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
759 AM PST WED NOV 19 2014

.DISCUSSION...19/12Z NAM IN. 19/12Z GFS IN THROUGH 72HR.

MIDDLE AND HIGH LEVEL CLOUDS OVER THE MEDFORD CWA THIS
MORNING...EXCEPT FOR LOW CLOUDS AND FOG IN THE UMPQUA BASIN. THERE
IS LITTLE OR NO AT THIS TIME...BUT THERE ARE STRONG WINDS OVER
SOME OF THE HIGHER TERRAIN.

THE FIRST OF TWO WEAK SYSTEMS WILL MOVE ONSHORE TODAY...
SPLITTING AS IT DOES SO...BUT NOT TO THE DEGREE EXHIBITED BY THE
MODELS YESTERDAY. MOST OF THE ASSOCIATED ENERGY WILL BE DIRECTED
INTO BRITISH COLUMBIA AND NORTHERN CALIFORNIA. MOST OF THE MEDFORD
CWA WILL SEE RAIN FROM THIS SYSTEM...AND THE HEAVIEST AMOUNTS WILL
FALL ALONG THE COAST AND COAST RANGE...EXTENDING SOUTH INTO
WESTERN SISKIYOU COUNTY. AMOUNTS WILL NOT BE ANYWHERE NEAR ENOUGH
TO CREATE FLOODING CONCERNS...AND SNOW LEVELS WILL REMAIN ABOVE
ALL BUT THE HIGHEST PEAKS.

THE SPLIT FLOW REGIME WILL PERSIST INTO THURSDAY...WHEN THE NEXT
SYSTEM WILL MOVE ONSHORE. ONCE AGAIN...MOST OF THE ENERGY WILL BE
DIRECTED INTO BRITISH COLUMBIA AND NORTHERN CALIFORNIA. THE POST-
FRONTAL SHOWERS FROM TODAY'S SYSTEM WILL BARELY BE DISSIPATED
BEFORE THE RAIN FROM THE THURSDAY SYSTEM BEGINS. THE BULK OF THE
ASSOCIATED PRECIPITATION WILL FALL ACROSS NORTHERN CALIFORNIA...
AND THE POST-FRONTAL SHOWERS WILL LARGELY DISSIPATE THURSDAY
NIGHT. SNOW LEVELS WILL BE 4000-5000 FEET...SO SOME PASSES MAY GET
SOME LIGHT SNOW.

A SHORT WAVE RIDGE WILL MOVE THROUGH THURSDAY NIGHT INTO
FRIDAY...BRINGING A BREAK IN THE ACTION AS WELL AS RAISING THE
SNOW LEVELS BACK ABOVE ALL BUT THE HIGHER PEAKS. STRONG ZONAL
FLOW WILL THEN SET UP WITH A STRONG JET ACROSS MOST OF THE
PACIFIC...AIMED RIGHT AT OREGON. SOUTHERN OREGON WILL BE SQUARELY
IN THE STORM TRACK FRIDAY NIGHT INTO SATURDAY. A WET AND WINDY
COLD FRONT WILL MOVE ONSHORE FRIDAY AFTERNOON. THIS WILL BE THE
STRONGEST SYSTEM IN THE SERIES. JUST ABOUT THE ENTIRE AREA FROM
THE CASCADES WEST WILL GET SIGNIFICANT PRECIPITATION FROM THIS
STORM. WINDS WILL ALSO BE A CONCERN...ESPECIALLY ALONG THE
COAST...OVER THE COASTAL WATERS...AND EAST OF THE CASCADES. NEAR
STORM FORCE WINDS ARE POSSIBLE NEAR THE COAST AS THE WINDS WILL
HAVE AN ONSHORE COMPONENT THAT WILL PROMOTE COASTAL WIND DAMMING.
A HIGH WIND WATCH WILL LIKELY BE ISSUED LATER TODAY. THE FRONT
WILL STALL OVER THE AREA AS IT BECOMES PARALLEL TO THE UPPER LEVEL
STEERING FLOW. WITH THE STRONG JET DYNAMICS ALOFT...IT WILL REMAIN
QUITE WET INTO SATURDAY WITH THE WEST FACING SLOPES OF THE COAST
RANGE AND CASCADES GETTING THE HEAVIEST PRECIPITATION. CURRENTLY
IT LOOKS LIKE ONLY THE PEAKS WILL GET APPRECIABLE SNOW FROM THESE
SYSTEMS AS THE SNOW LEVELS WILL REMAIN WELL ABOVE THE PASSES...AT
LEAST THROUGH FRIDAY NIGHT.

ANOTHER WEAKER DISTURBANCE WILL MOVE ONSHORE SATURDAY...BRINING
ANOTHER ROUND OF PRECIPITATION TO THE AREA. PRECIPITATION AMOUNTS
WILL BE MUCH LESS THAN THE FRIDAY SYSTEM...BUT MOST OF THE CWA
WILL GET MEASURABLE AMOUNTS. IT MAY BE A BIT BREEZY OVER THE
RIDGES AND EAST OF THE CASCADES AS WELL...BUT ONCE AGAIN THEY WILL
BE LIGHTER THAN THEY WILL BE WITH THE FRIDAY SYSTEM.

&&

.AVIATION...FOR THE 19/12Z TAFS...IFR CIGS WILL PERSIST ONCE AGAIN IN
THE UMPQUA BASIN INCLUDING KRBG THROUGH AT LEAST 18Z, THEN CIGS WILL
IMPROVE TO VFR AS A FRONTAL BOUNDARY APPROACHES. ELSEWHERE, VFR
CONDITIONS WILL CONTINUE THROUGH AT LEAST 20Z TODAY. A FRONTAL
BOUNDARY WILL MOVE IN THIS AFTERNOON RESULTING IN CIGS LOWERING TO
MVFR AND AND OCCASIONAL IFR WEST OF THE CASCADES LATE THIS AFTERNOON
INTO TONIGHT WITH PARTIAL MOUNTAIN OBSCURATION. WINDS ARE EXPECTED
TO INCREASE NEAR 1500 FEET AGL AND ABOVE NEAR KMFR AND IT WILL BE A
CLOSE CALL FOR WIND SPEED SHEAR BETWEEN 20-23Z. FUTURE SHIFTS WILL
NEED TO TAKE ANOTHER LOOK AT THIS.

EAST OF THE CASCADES...VFR CONDITIONS SHOULD LAST MOST OF THE DAY.
THERE IS A CHANCE THAT MVFR CIGS COULD DEVELOP AT KLMT PRIOR TO 23Z.
SOUTH WINDS AT THE SURFACE AND ALOFT WILL INCREASE THIS AFTERNOON
AND CONTINUE INTO THIS EVENING THEN DECREASE TONIGHT. MVFR CIGS ARE
LIKELY TO CONTINUE TONIGHT. -PETRUCELLI

&&

.MARINE...UPDATED 4 AM PST NOV 19 2014...THE MAIN CONCERN AHEAD IS
FRIDAY AFTERNOON AND FRIDAY NIGHT. THE MODELS CONTINUE TO SHOW GOOD
AGREEMENT SHOWING A STRONG WARM FRONT APPROACHING THE WATERS LATE
FRIDAY MORNING OR EARLY AFTERNOON. SOUTH WINDS WILL INCREASE DURING
THE DAY. CURRENTLY THE KACV-KOTH GRADIENT IS CLOSE TO 10 MB WITH BL
WINDS IN THE 40-50 KT RANGE WITH 850 MB WINDS FROM AROUND 220 AT 50-
60 KTS LATE FRIDAY AFTERNOON AND EVENING. THIS COULD RESULT IN WINDS
GETTING CLOSE TO STORM FORCE FOR A FEW HOURS. NOW IF THE TIMING ENDS
UP EARLIER, THEN THIS WILL COME AT A TIME WHEN HIGH TIDE REACHES
IT'S MAX LATE FRIDAY MORNING RESULTING IN HIGHER WAVES AT PORT
ORFORD. THIS WILL NEED TO BE MONITORED CLOSELY.

UNTIL THEN...A WEAK FRONTAL BOUNDARY WILL MOVE THROUGH AND BRING LOW
END SMALL CRAFT WINDS TO THE OUTER WATERS. MEANWHILE A MODERATE
SOUTHWEST SWELL WILL RESULT IN SMALL CRAFT FOR SEAS THROUGH THURSDAY
AFTERNOON. IT'S POSSIBLE SEAS WILL COME DOWN BRIEFLY THURSDAY NIGHT
BEFORE INCREASING AGAIN FRIDAY. -PETRUCELLI
