AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
850 AM PST SUN DEC 21 2014

.SHORT TERM...MOIST ONSHORE FLOW WILL CONTINUE TO BRING MODERATE
RAIN INTO WESTERN PORTIONS OF THE CWA TODAY WITH MAINLY LIGHT
RAIN EAST OF THE CASCADES. MODELS ARE IN AGREEMENT WITH CONTINUED
RAIN TODAY AND SHOWING RAIN DECREASING THIS EVENING AND TONIGHT AS
RIDGING BEGINS TO BUILD INTO THE AREA BRINGING DRIER NORTHWEST
FLOW. RAINFALL WILL DIMINISH FOR MOST AREA BY LATE MONDAY
AFTERNOON INTO MONDAY EVENING, WITH ONLY SOME CONTINUED LIGHT RAIN
EXPECTED IN THE SOUTHERN OREGON CASCADES AND OTHER HIGHER TERRAIN.

THE MAIN CONCERN WITH THIS FORECAST CYCLE WILL BE WITH THE FLOOD
POTENTIAL AS RAINFALL THAT OCCURRED OVER THE LAST 2 DAYS AND
CONTINUED MODERATE RAINFALL TODAY, BRINGS SIGNIFICANT RISES TO
AREA RIVERS. FLOOD WARNINGS ARE IN EFFECT FOR THE COQUILLE RIVER
AT COQUILLE AND SMALL STREAMS IN THE SITKUM AND POWERS AREAS AS
WELL AS FOR THE SOUTH UMPQUA RIVER AT TILLER. ALSO A FLOOD WATCH
IS OUT FOR THE SOUTH FORK OF THE COQUILLE RIVER AT MYRTLE POINT.
AREAS FLOOD WATCHES ARE CONTINUING TODAY FOR SMALL STREAM AND
URBAN FLOODING POTENTIAL DUE HEAVY RAIN FOR AREAS FROM THE
SOUTHERN OREGON CASCADES WEST. EXPECT TO ISSUE UPDATES ON THESE
RIVER PRODUCTS LATER THIS MORNING AND THIS AFTERNOON.

STRONG GUSTY WINDS HAVE LOWERED FOR COASTAL LOCATIONS AND INTO
THE SHASTA VALLEY BUT HIGH WINDS WILL CONTINUE FOR THE CASCADES
AND FOR AREAS EAST OF THE CASCADES, ESPECIALLY SUMMER LAKE AND THE
MOUNTAINS WHERE A HIGH WIND WARNING CONTINUES TODAY INTO THIS
EVENING.

&&

.AVIATION...FOR THE 21/12Z TAF CYCLE...A MOIST PACIFIC JET STREAM
REMAINS AIMED AT OUR AREA. WIDESPREAD MTN OBSCURATION WITH RAIN AND
MVFR CIGS/VIS WILL CONTINUE THROUGH THE DAY. LOW LEVEL WIND SHEAR
WILL AFFECT ALL AREAS. LITTLE IMPROVEMENT IN CEILINGS TONIGHT AS
HIGH PRESSURE BEGINS TO BULD WITH VALLEY IFR FOG BECOMING WIDESPREAD
INLAND. MTS

&&

.MARINE...UPDATED 730 AM PST SUN DEC 21 2014...WINDS HAVE DECREASED
BELOW SMAL CRAFT ADVISORY AND BOTH SWELL AND WIND WAVE HAVE
DECREASED. MODERATE WEST SWELL WILL CONTINUE AND THUS A SMALL CRAFT
FOR HAZARDOUS SEAS HAS BEEN ISSUED THROUGH WEDNESDAY WITH A NEW LONG

.PREV DISCUSSION... /ISSUED 350 AM PST SUN DEC 21 2014/

DISCUSSION...A MAJOR PRECIPITATION EVENT CONTINUES IN SOUTHERN
OREGON AND IS CAUSING FLOODING IMPACTS AT THE COAST...COAST
RANGE...CASCADE FOOTHILLS...AND CASCADES. RIVERS CONTINUE TO
RISE...AND WILL GENERALLY CONTINUE THROUGH THIS MORNING AT
LEAST...AND INTO THE AFTERNOON IN SOME PLACES.

RAIN RATES CONTINUE TO BE HIGH THIS MORNING...WITH 1 HOUR RATES OF A
THIRD TO HALF AN INCH ACROSS PORTIONS OF COOS...CURRY...AND DOUGLAS
COUNTIES.  A WHOPPING 24 HOUR RAINFALL TOTAL NEAR 9 INCHES HAS
OCCURRED AT RED MOUND NEAR THE CURRY COUNTY COAST. IN ADDITION...THE
AFTERNOON BALLOON SOUNDING REGISTERED 1.07 INCHES OF PRECIPITABLE
WATER WHICH RANKS 7TH FOR DECEMBER SOUNDINGS AND IS 3 STANDARD
DEVIATIONS HIGHER THAN NORMAL. IN OTHER WORDS...THIS IS A VERY JUICY
AIR MASS.

THE DURATION OF THE HEAVY RAIN IS THE MOST SIGNIFICANT ASPECT OF
THIS SYSTEM...AND WHEN ALL IS SAID AND DONE THERE WILL HAVE BEEN
ESSENTIALLY 48 HOURS OF 500 KG/MS INTEGRATED VAPOR TRANSPORT ACROSS
THE AREA. THESE IVT VALUES SUGGEST THIS TYPE OF RAIN EVENT OCCURS
ONLY ONCE IN 5-10 YEARS FOR THE COAST AND CASCADES. IMPACTS THUS FAR
HAVE BEEN AT LEAST ONE RIVER...THE EAST FORK OF THE COQUILLE NEAR
SITKUM...OVERFLOWING ITS BANKS LATE LAST NIGHT WHICH PROMPTED THE
ISSUANCE OF AN AREAL FLOOD WARNING FOR EASTERN COOS COUNTY THAT WILL
CONTINUE THROUGH THIS MORNING. AREAL FLOOD WATCHES COVER MUCH OF THE
REST OF THE AREA FROM THE CASCADES WEST. A FLOOD WARNING CONTINUES
FOR THE COQUILLE AT COQUILLE AT FLSMFR...WITH MINOR FLOODING
FORECAST TO BEGIN THIS AFTERNOON. ADDITIONALLY...HIGH WATER HAS BEEN
REPORTED ON HIGHWAY 101 AT THE COAST AND HIGHWAY 138 IN THE CASCADE
FOOTHILLS...WITH ROCKS THE SIZE OF BASKETBALLS FALLING ON HIGHWAY
138 AND BEING REPORTED BY ODOT. NEEDLESS TO SAY...TRAVEL ON THESE
ROADS THIS MORNING WILL BE HAZARDOUS...AND DRIVERS NEED TO USE
EXTRA CAUTION IF VENTURING OUT IN THESE AREAS.

SNOW LEVELS ARE HIGH AT THIS MOMENT...ABOVE 7000 FEET...AND WILL
REMAIN HIGH THROUGH TODAY. WINDS WILL CONTINUE TO BE GUSTY EAST OF
THE CASCADES AND A HIGH WIND WARNING AND WIND ADVISORY CONTINUE AT
NPWMFR.

VALLEYS LIKE THE ROGUE HAVE BEEN SHELTERED FROM THE MOST SIGNIFICANT
RAIN WITH ONLY 0.22 INCHES IN THE PAST 24 HOURS...WITH DOWNSLOPING
DRYING THE VALLEY OUT COMPARED TO HIGHER TERRAIN. MEDFORD STILL WILL
LIKELY SEE AT LEAST A HALF INCH OF RAIN FROM THIS SYSTEM THOUGH.

ATTENTION THEN TURNS TO A CHRISTMAS EVE COLD UPPER TROUGH WHICH
ARRIVES THE AFTERNOON OR EVENING OF THE 24TH...AND BRINGS WITH IT A
GOOD CHANCE FOR A WHITE CHRISTMAS AT ELEVATIONS ABOVE 3000 FEET.
MODEL CONSENSUS AT THIS TIME BETWEEN THE EC AND GFS SUGGESTS FOLKS
COULD GO TO SLEEP CHRISTMAS EVE WITH RAIN OR RAIN/SNOW MIX...OR DRY
CONDITIONS EAST OF THE CASCADES...AND WAKE UP TO A FEW INCHES OR
MORE OF THE WHITE STUFF. WE WILL BE WORKING HARD TO FINE-TUNE THIS
FORECAST IN THE NEXT FEW SHIFTS...AND CONVEY ANY WEATHER MESSAGES
ABOUT THIS POTENTIALLY SIGNIFICANT WINTRY EVENT.
