AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
909 AM PST SUN DEC 13 2015
.DISCUSSION...AS EXPECTED CONDITIONS WENT ISOTHERMAL EARLY THIS
MORNING AND WE HAD RAIN TURN OVER TO A BRIEF PERIOD OF MODERATE
TO HEAVY WET SNOW FOR MOST WESTSIDE LOCATIONS DOWN NEAR THE VALLEY
FLOORS. FROM REPORTS WE HAVE BEEN GETTING THIS MORNING. A FEW
INCHES OF SNOW HAD FALLEN MAINLY ABOVE 1500 FEET WITH A TRACE TO 2
INCHES OF SLUSH IN THE VALLEYS INCLUDING MEDFORD PROPER AND
ROSEBURG. THE HEAVIEST PRECIPITATION HAS MOVED SOUTH INTO NORTHERN
CAL. BECAUSE OF THAT WE HAVE SEEN WET SNOW TURN BACK OVER TO RAIN
HERE AT THE OFFICE. THERE'S A CHANCE SNOW LEVELS WILL COME UP SOME
THIS MORNING, HOWEVER AN UPPER TROUGH WILL MOVE INTO THE AREA
BRINGING IN COLDER AIR ALOFT AND SHOWERS WILL INCREASE. SOME OF
THE SHOWERS COULD BE MODERATE TO HEAVY WHICH WILL TEMPORARILY DRAG
SNOW LEVELS DOWN ENOUGH FOR SNOW TO TEMPORARY ACCUMULATE ON ROADS.
THE CHANCE FOR ACCUMULATING SNOW WILL BE HIGHER AFTER DARK AND
TEMPERATURES DROP. ADJUSTED THE WINTER WEATHER HEADLINES WEST OF
THE CASCADES TO REFLECT LOWER SNOW LEVELS. -PETRUCELLI
&&
.AVIATION...FOR THE 13/12Z TAF CYCLE...PRECIPITATION HAS DECREASED
THIS MORNING, BUT SHOWERS WILL INCREASE THIS AFTERNOON RESULTING
IN MOUNTAIN OBSCURATIONS AND A MIX OF IFR AND MVFR CONDITIONS.
FREEZING LEVELS WILL FALL TO 2500 FT MSL THEN REMAIN LOW WITH
ADDITIONAL SHOWERS AND SNOW SHOWERS TONIGHT.
&&
.MARINE...UPDATED 350 AM PST SUNDAY 13 DEC 2015....NORTHWEST WINDS
WILL INCREASE TODAY AND PEAK THIS EVENING THEN LOWER ON MONDAY.
GUSTS UP TO 35 KT ARE POSSIBLE IN THE EVENING. LARGE AND VERY STEEP
SEAS DOMINATED BY A WEST SWELL AT 13 TO 14 SECONDS ARE EXPECTED
THROUGH TONIGHT THEN SEAS WILL GRADUALLY LOWER ON MONDAY. SEAS ARE
EXPECTED TO REMAIN STEEP MONDAY AND TUESDAY. ANOTHER FRONT ARRIVES
LATE WEDNESDAY INTO THURSDAY MORNING. THIS MAY BRING A PERIOD OF
STRONG GUSTY SOUTH WINDS AS WELL AS STEEP TO VERY STEEP SEAS. /CC
&&
.PREV DISCUSSION... /ISSUED 518 AM PST SUN DEC 13 2015/
UPDATE...HAVE UPDATED THE FORECAST TO INCLUDE SNOW DOWN TO 500
FEET IN THE VALLEYS WEST OF THE CASCADES THIS MORNING AS HEAVY
PRECIPITATION RATES HAVE BEEN ABLE TO LOWER THE SNOW LEVEL DOWN
EVEN LOWER THAN PREVIOUSLY ANTICIPATED. LATEST WEB CAMS ARE
SHOWING SOME ACCUMULATING SNOW ON INTERSTATE 5 NEAR ROSEBURG AND
MEDFORD. THE HEAVY PRECIPITATION BAND IS EXPECTED TO GRADUALLY
SHIFT SOUTH AND EAST OF THE AREA THIS MORNING...SO SNOW RATES WILL
NOT BE AS HIGH AS THEY ARE RIGHT NOW. EXPECT SNOW TO TAPER OFF
MID-MORNING AND THE SNOW LEVEL TO RISE SLIGHTLY LATE THIS MORNING
AND THIS AFTERNOON. EVEN SO, EXPECT TRAVEL-RELATED IMPACTS IN
THE WEST SIDE VALLEYS THIS MORNING. ROADS WILL BE VERY SLIPPERY
AND HAZARDOUS IN SOME AREAS, WHILE WET IN OTHERS. PLEASE USE
CAUTION AND TAKE SOME EXTRA TIME TO REACH YOUR DESTINATION THIS
MORNING. SPILDE
PREV DISCUSSION... /ISSUED 357 AM PST SUN DEC 13 2015/
DISCUSSION...VERY HEAVY PRECIPITATION IS MOVING THROUGH THE AREA
AT THIS TIME AS A DEEP MOIST PLUME (ATMOSPHERIC RIVER) ASSOCIATED
WITH A STRONG COLD FRONT PRESSES IN FROM THE PACIFIC. RAINFALL
RATES IN THE LAST COUPLE OF HOURS HAVE BEEN IMPRESSIVE...IN SOME
CASES...0.25-0.50 IN/HR OVER THE WEST SIDE VALLEYS. ALONG THE
CURRY COAST AND THE COAST RANGES, RAINFALL RATES EARLIER WERE
0.40-0.80 IN/HR. THIS HAS PROMPTED THE ISSUANCE OF SEVERAL FLOOD
PRODUCTS, INCLUDING AN AREAL FLOOD WARNING FOR PORTIONS OF
SOUTHERN COOS, CURRY AND WESTERN JOSEPHINE COUNTIES AND URBAN AND
SMALL STREAM FLOOD ADVISORIES FOR THE CITIES OF CENTRAL DOUGLAS
AND JACKSON COUNTIES. THESE RAIN RATES LIKELY CONTINUE FOR THE
NEXT FEW HOURS, AND ADVISORIES MAY NEED TO BE UPGRADED TO AREAL
FLOOD WARNINGS. SEVERAL STREAMS AND CREEKS ARE ALREADY RUNNING OUT
OF THEIR BANKS AND MAIN STEM RIVER FLOODING IS OCCURRING ON THE
COQUILLE AND PORTIONS OF THE UMPQUA. THIS MAY TRANSLATE TO THE
ROGUE RIVER IN SOME AREAS THIS MORNING AS RAINFALL CONTINUES TO
POUND DOWN.
MEANWHILE, SNOW CONTINUES TO PILE UP OVER THE MOUNTAINS...EXPECT
STORM TOTALS OF 1 TO 3 FEET OVER THE CASCADES AND SISKIYOUS WITH
MANY AREAS IN THE FOOTHILLS AND OVER THE EAST SIDE RECEIVING A
SOLID 6-12 INCHES. SNOW LEVELS ROSE BRIEFLY OVERNIGHT ALLOWING
SNOW TO CHANGE TO RAIN IN SOME AREAS UP TO ABOUT 5500 FEET, BUT
THESE LOCATIONS WILL CHANGE BACK TO SNOW THIS MORNING AS THE COLD
FRONT PUSHES THROUGH. LATEST OBSERVATIONS ARE SHOWING
TEMPERATURES WET-BULBING DOWN HARD BEHIND THE FRONT AND SNOW
LEVELS ARE PLUNGING VERY QUICKLY. MT YONCALLA, WHICH IS AT 1800
FEET, IS SHOWING A TEMP OF 34F AT 3 AM AND NORTH BANK, JUST ABOVE
ROSEBURG AT 1900 FEET IS SHOWING 32F. SNOW LEVELS COULD REACH AS
LOW AS 1000 FEET THIS MORNING AS THE BACK EDGE OF THE HEAVY
PRECIPITATION MOVES THROUGH. SO, YES, THAT MEANS THERE COULD EVEN
BE SOME WET SNOW DOWN INTO THE ROGUE AND ILLINOIS VALLEYS FOR A
WHILE. SNOW ACCUMULATIONS ARE LIKELY TO REMAIN MOSTLY ABOVE 2000
FEET, HOWEVER, AS SURFACE TEMPERATURES WILL HAVE DIFFICULTY
GETTING DOWN TO FREEZING. BUT, THE MAIN PASSES (SEXTON, STAGE,
SMITH, CANYON CREEK) CAN ALL HAVE SOME ACCUMULATING SNOW THIS
MORNING. SEE WSWMFR FOR SPECIFIC DETAILS.
THE VERY HEAVY PRECIPITATION ASSOCIATED WITH THE FRONT WILL PUSH
TO THE EAST OF THE CASCADES BY MID MORNING, BUT SHOWERS WILL
PERSIST BEHIND IT. COLD AIR ALOFT ARRIVING FROM THE OCEAN WILL
BRING ISOLATED THUNDERSTORMS THAT MAY CONTAIN SMALL HAIL AND GUSTY
WINDS OVER THE COASTAL WATERS AND ALONG THE IMMEDIATE COAST.
ANOTHER DISTURBANCE WILL ARRIVE ON THE BACK SIDE OF THE TROUGH
LATER TODAY AND TONIGHT. WITH SNOW LEVELS ALREADY ON THE LOW
SIDE, ACCUMULATING SNOW IS LIKELY AGAIN ALONG AND WEST OF THE
CASCADES. HEAVIER SNOW SHOWERS WILL FAVOR THE NORTHWEST FACING
SLOPES, BUT ACCUMULATING SNOW IS POSSIBLE DOWN TO 1000 FEET IN THE
UMPQUA, ROGUE AND ILLINOIS VALLEYS.
SNOW SHOWERS LINGER MONDAY INTO MONDAY NIGHT, BUT RIDGING FROM THE
PACIFIC SHOULD BRING DRIER WEATHER BY TUESDAY. SPILDE
