AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
834 PM PDT MON MAR 26 2012
.DISCUSSION...IMPACTS ARE BEGINNING TO BE FELT ACROSS THE CWA THIS
EVENING AS A LARGE OFFSHORE STORM NEAR 50N 140 W SENDS A STRONG
FRONTAL SYSTEM TOWARD THE COAST. WE'LL COVER THE THREATS BELOW.
FIRST, THE SNOW. THIS IS LOOKING MORE AND MORE LIKE A CLASSIC
UPSLOPE SNOW EVENT SETTING UP NEAR MOUNT SHASTA CITY TONIGHT AND
CONTINUING THROUGH TOMORROW NIGHT. LATEST WEB CAMS ARE ALREADY
SHOWING ACCUMULATING SNOW UP AT SNOWMAN'S SUMMIT. STEADY SOUTH
700MB FLOW OF 50-60KT OVERNIGHT INTO EARLY TUESDAY MORNING WILL
INCREASE TO NEAR 70KT TUESDAY AFTERNOON AND EVENING AS A
115-125KT JET STREAK HEADS INTO NORTHERN CALIFORNIA. THIS WILL
MAXIMIZE UPWARD MOTION IN CONCERT WITH FAVORABLE SNOW GROWTH IN
THE DENDRITIC ZONE (-12 TO -18C). NAM12 IS INDICATING 850 TEMPS
BELOW 0C THROUGHOUT THE EVENT, SO EXPECTING A HEAVY WET SNOW.
PRECIPITATION RATES DURING THE HEIGHT OF THE EVENT ARE LIKELY TO
REACH .20-.30 OF AN INCH/HOUR, WHICH WITH EVEN A SLIGHTLY LOWER
THAN TYPICAL 10 TO 1 SNOW RATIO, WOULD BE 1-3"/HOUR. WITH THE
ENHANCED PRECIPITATION RATES EXPECTED TUESDAY ALSO EXPECT SNOW
LEVELS TO LOWER DOWN TO DUNSMUIR. THE IMPACT WILL BE GREATEST
ALONG I-5 FROM SOUTH WEED TO DUNSMUIR. WE HAVE ISSUED AN UPDATE
THIS EVENING TO LOWER THE SNOW LEVEL DOWN TO AROUND DUNSMUIR AND
ALSO INDICATE SNOW AMOUNTS UP TO 3 FEET POSSIBLE ABOVE 4000 FEET.
THIS MUCH SNOW WILL SNAP TREE LIMBS AND CAUSE POWER OUTAGES. THE
SHEER WEIGHT OF THE SNOW MAY ALSO CAUSE ROOFS TO COLLAPSE. PLEASE
REFER TO THE PDXWSWMFR PRODUCT FOR MORE ON THE DETAILS.
SECOND, THE WINDS. SOUTH WINDS HAVE ALREADY BEEN GUSTING PAST 55
MPH AT THE COAST...ESPECIALLY FROM CAPE BLANCO SOUTHWARD. WHILE
IT WILL ALSO BE WINDY AT TIMES ALONG THE NORTH COAST...SINCE THIS
SYSTEM IS TAKING ON A NEGATIVE TILT...THE EFFECTIVE BACKING OF
BOUNDARY LAYER WINDS TO THE SOUTHEAST SHOULD KEEP THE STRONGEST
GUSTS OVER THE HEADLANDS AND COAST SOUTH OF THE CAPE. MEANWHILE
THE PRESSURE GRADIENT BETWEEN MEDFORD AND REDDING IS ABOUT 6 MB
THIS EVENING AND IS EXPECTED TO INCREASE TO AROUND 8 MB TUESDAY.
IT IS THE BACKING OF WINDS TO THE SOUTHEAST THAT ALLOWS WINDS TO
SURFACE HERE IN MEDFORD SINCE THEY ALIGN WITH OUR SOUTHEAST TO
NORTHWEST ORIENTED VALLEY. AS A RESULT...EXPECTING SOME STRONG
WIND GUSTS PARTICULARLY NEAR ASHLAND AND THE SOUTH END OF THE
VALLEY. IT ALMOST GOES WITHOUT SAYING THAT THIS TYPE OF PATTERN
WILL ALSO PRODUCE VERY STRONG WINDS THROUGH THE SHASTA VALLEY AND
ALSO OVER THE EAST SIDE. PLEASE REFER TO PDXNPWMFR FOR THE
SPECIFICS.
THIRD, THE HEAVY RAIN. AN AREAL FLOOD WATCH HAS BEEN ISSUED FOR
THE OREGON COAST AND THIS WILL LIKELY NEED TO BE UPGRADED TO
WARNING LATER TONIGHT OR TUESDAY AS RAINFALL RATES INCREASE. MORE
RAIN ON ALREADY SATURATED GROUND WILL CAUSE SMALLER RIVERS AND
STREAMS TO SWELL. MAIN STEM RIVERS WILL BE A BIT SLOWER TO RESPOND
BUT WILL ALSO RISE SIGNIFICANTLY THIS WEEK AS MULTIPLE STORM
SYSTEMS IMPACT THE AREA WITH HEAVY RAINFALL. THE COQUILLE WILL BE
PARTICULARLY TROUBLESOME WITH MINOR TO MODERATE FLOODING EXPECTED
TO BEGIN LATER TUESDAY NIGHT AND THEN PERHAPS PERSIST INTO THE
WEEKEND. SPILDE
&&
.AVIATION...VFR CONDITIONS EXIST ACROSS MOST OF THE VALLEYS THIS
EVENING. THE EXCEPTIONS ARE THE UPSLOPE SOUTH FLOW AREAS OF SISKIYOU
COUNTY AND CURRY COUNTY, AS WELL AS PORTIONS OF KLAMATH AND
DOUGLAS COUNTY WHERE MVFR TO LOCAL IFR EXISTS. THE MOUNTAINS
REMAIN PARTIALLY OBSCURED. THIS WILL CONTINUE TO RESULT IN VIRGA
OR LIGHT PRECIPITATION. OVERNIGHT THROUGH TUESDAY STRONG WINDS
ABOVE AND THROUGH THE TERRAIN WILL BE THE PRIMARY FLIGHT HAZARD
FOR MOST LOCATIONS RESULTING IN A HIGH LIKELIHOOD OF LOW LEVEL
WIND SHEAR AND TURBULENCE. CEILINGS AND VISIBILITIES WILL CHANGE
VERY LITTLE OVERNIGHT EXCEPT IN UPSLOPE AREAS ALONG THE COAST AND
ACROSS SISKIYOU COUNTY WHERE IFR WILL DOMINATE. ON TUESDAY
PRECIPITATION WILL INCREASE ACROSS THE AREA LATE IN THE DAY INTO
THE EVENING AS THE FRONT BEGINS MOVING INLAND. THIS WILL RESULT IN
FALLING CEILINGS AND VISIBILITIES MOSTLY TUESDAY EVENING AND
NIGHT. BTL
&&
.PREV DISCUSSION... /ISSUED 330 PM PDT MON MAR 26 2012/
SHORT TERM...AN 18Z ASCAT PASS SHOWS MODELS HAVE A VERY GOOD
HANDLE ON THE WINDS THUS FAR AS THE GALES FROM THE PASS MATCHED
ALMOST PERFECTLY WITH THE PROGS. THESE WINDS WILL CONTINUE TO
STRENGTHEN AND MOVE CLOSER TOWARDS THE SHORE THIS AFTERNOON. DID
NOT MAKE ANY CHANGES TO THE HIGH WIND WARNINGS FOR THE COASTAL
AREAS. STILL EXPECTING GUSTS TO NEAR 50MPH THIS EVENING AND
OVERNIGHT. WITH THE ALREADY SATURATED GROUND AND MORE RAIN MOVING
IN...EVEN THOSE THE WINDS ARE NOT EXTREME FOR COASTAL AREAS, THEY
COULD EASILY TOPPLE TREES AND POSSIBLY POWER LINES.
A WARM FRONTAL FEATURE IS STARTING TO TAKE SHAPE ACROSS NORTHERN
CALIFORNIA IN FRONT OF THE STORM. IT IS SPREADING SOME LIGHT RAIN
FROM SOUTHWEST TO NORTHEAST AND EVEN CREATING SOME LIGHT SNOW
SHOWERS FOR KFALLS. GRADIENTS CONTINUE TO TIGHTEN ACROSS THE AREA
THIS AFTERNOON. MFR TO REDDING HAS INCREASED 3MB OVER THE PAST 5HRS.
STARTING TO SEE SOME GUSTIER WINDS AT HIGHER ELEVATIONS AND ON THE
EAST SIDE OF THE CASCADES. FOR THIS REASON WE BUMPED UP THE TIMING
OF THE WIND ADVISORY FOR THE ROGUE VALLEY BY 6HRS. WINDS WILL LIKELY
START AT THE SOUTH END OF THE VALLEY AND WORK THEIR WAY INTO MEDFORD
LATER THIS EVENING. ALSO ELECTED TO GO FROM HIGH WIND WATCHES FOR
THE SHASTA VALLEY AND LAKE CO TO HIGH WIND WARNINGS STARTING LATER
TONIGHT AND LATE MORNING TOMORROW RESPECTIVELY. MEANWHILE EXTENDED
THE REST OF THE EAST SIDE WIND ADVISORIES TIL EARLY WEDNESDAY
MORNING. IF FUTURE MODEL RUNS COME IN ANY STRONGER, WE MAY HAVE TO
CONSIDER A HIGH WIND WARNING FOR THE SOUTH END OF THE CASCADES TO
INCLUDE MT ASHLAND.
UPGRADED THE WINTER STORM WATCHES FOR NORTHERN CALIFORNIA TO WINTER
STORM WARNINGS. ALSO INCLUDED A WINTER WEATHER ADVISORY FOR PORTIONS
OF THE EAST SIDE AS AREAS LIKE CHEMULT AND PORTIONS OF HIGHWAYS 140
AND 97 WILL LIKELY SEE A FEW INCHES TUESDAY NIGHT THROUGH WEDNESDAY
MORNING. NAM STILL SHOWING 70KTS AT 700MB TUESDAY AFTERNOON PUSHING
PLENTY OF MOISTURE INTO THE MOUNT SHASTA AREA. UNLIKE THIS PAST
SATURDAY, THE FLOW WITH THIS SYSTEM IS STRONGER AND MORE
SOUTHWESTERLY. UPSLOPE WILL STILL BE A DRIVING COMPONENT IN
PRECIPITATION RATES, BUT SOUTHWEST SLOPES WILL RECEIVE THE BRUNT OF
THE SNOW THIS TIME. HIGH PRECIPITATION RATES WILL ALSO CAUSE LOCALLY
LOWER SNOW LEVELS AROUND THE MOUNT SHASTA AREA. GENERALLY SNOW WILL
ACCUMULATE ABOVE 3500 FEET...THOUGH SNOW COULD FALL AS LOW AS 2500
FEET DURING THE HEAVIER SHOWERS. THIS SNOW WILL BE OF THE HEAVY AND
VERY WET VARIETY. WHEN COUPLED WITH THE GUSTY WINDS...POWER LINES
MAY GIVE WAY UNDER THE WEIGHT. CONFIDENCE IS ONLY MODERATE IN
ROAD ACCUMULATIONS NEAR 3500 FEET DURING THE DAY TUESDAY AS
SURFACE TEMPERATURES ARE FORECASTED TO REACH NEAR 40 DEGREES.
WITH ANOTHER SHORT BREAK ON WEDNESDAY, ALL MODELS ARE IN
GOOD AGREEMENT FOR THE NEXT HEAVY PRECIPITATION EVENT TO START
VERY EARLY THURSDAY. SNOW LEVELS WILL RISE TOWARDS 5000 FEET
THURSDAY. SO THE BIGGEST IMPACT FROM THIS SYSTEM LOOKS TO BE
ANOTHER BOUT OF HIGH WINDS AND HEAVY RAIN. WITH COMBINED
ACCUMULATIONS WITH THESE EVENTS, THE MOST SIGNIFICANT COASTAL RIVER
RISES ARE EXPECTED AS WE ENTER THE WEEKEND.
LONG TERM...THURSDAY, MARCH 29TH TO TUESDAY, APRIL 3RD...
AT THE BEGINNING OF THIS PERIOD A 150 KNOT WEST TO EAST JET STREAM
WILL BE CUTTING ACROSS THE CENTRAL AND EASTERN PACIFIC AROUND 40
DEGREES NORTH LATITUDE. THIS WILL POWER A LARGE PARENT LOW IN THE
GULF OF ALASKA. THURSDAY THROUGH NEXT WEEKEND THIS JET STREAM WILL
DRIVE STORMINESS INTO THE AREA AS A BROAD LONG WAVE TROUGH IS CARVED
OUT IN THE GULF OF ALASKA. FROM SUNDAY THROUGH THE FIRST FEW DAYS OF
APRIL MODEL GUIDANCE HAS BEEN VERY INCONSISTENT. THE GFS40 KEEPS
NEAR WEST TO EAST MORE ZONAL FLOW OVER THE AREA AND THE BULK OF THE
UPPER TROUGH OFFSHORE THROUGH DAY 10, WHILE THE ECMWF BRINGS THE
LONG WAVE TROUGH AXIS ONTO THE WEST COAST AND INTO THE AREA. DUE TO
FAIRLY GOOD ECMWF RUN TO RUN CONSISTENCY AND EXCELLENT AGREEMENT
AMONGST THE ECMWF ENSEMBLE MEMBERS VERY LITTLE CHANGE WAS MADE TO
THE FORECAST BEYOND DAY 5. THIS YIELDS A SOLUTION CLOSE TO THE ECMWF
ENSEMBLES, WHICH KEEPS SHOWERS GOING INTO EARLY NEXT WEEK. IT SHOULD
BE NOTED THAT LONG RANGE GUIDANCE HAS BEEN STRONGLY HINTING AT A
PATTERN CHANGE SOMETIME BETWEEN APRIL 3RD AND THE 8TH. THIS WOULD
BRING DRIER AND WARMER MORE TYPICAL SPRING TYPE WEATHER IN THE FORM OF
SLIGHTLY WARMER AND DRIER THAN NORMAL CONDITIONS TO THE AREA.
IT SHOULD BE NOTED THAT THE EFFECTS OF A STRONG MADDEN JULIAN
OSCILLATION WILL CONTINUE TO TRANSLATE FROM THE WESTERN PACIFIC INTO
THE WESTERN HEMISPHERE DURING THIS PERIOD. THIS MEANS UPPER LEVEL
CONDITIONS WILL CONTINUE TO REMAIN FAVORABLE FOR SIGNIFICANT STORM
ACTIVITY AND THE FLOW WILL BE FAVORABLE FOR SIGNIFICANT
PRECIPITATION THROUGH ABOUT THE END OF THE MONTH.
A STRONG STORM SYSTEM WILL DRIVE ONTO THE COAST ON THURSDAY WITH THE
FRONT STALLING ALONG AND NEAR THE COAST. IT WILL WEAKEN SOME AS IT
MOVES ONTO THE WEST SIDE ON FRIDAY. FRIDAY INTO SATURDAY...THE NEXT
BATCH OF ENERGY RIDING INTO THE FRONTAL BOUNDARY FROM THE PACIFIC
WILL SEND AN ENHANCED COLD FRONT INLAND ACROSS THE AREA. WE WILL
NEED TO WATCH THIS FRIDAY SATURDAY TIME PERIOD, AS THE MODELS HAVE
BEEN INDICATING AN APPRECIABLE TO STRONG WAVE OF LOW PRESSURE RIDING
ALONG THE FRONT FRIDAY NIGHT INTO SATURDAY. AREAS WHERE THIS FRONT
LIES WILL GET HEAVY PRECIPITATION, BUT WHERE THAT OCCURS COULD BE
ANYWHERE ALONG THE OREGON COAST AT THIS TIME. THE ECMWF OPERATIONAL
RUN ALSO INDICATES A VERY STRONG LOW COMING INSIDE OF 130 WEST
DURING THIS TIME PERIOD. THIS SEEMS TOO STRONG GIVEN THE SEASON, SO
HAVE NOT BOUGHT INTO THIS AT THIS TIME. ON THE BACK SIDE OF THIS
FRONTAL SYSTEM BOTH MODELS HAVE BEEN SHOWING SNOW LEVELS ENDING NEAR
2000 FEET OVER THE LAST TWO DAYS IN THE SUNDAY TO MONDAY MORNING
TIME FRAME.
CONCERNS STILL REMAIN FOR POTENTIAL FLOOD PROBLEMS ON THE COQUILLE
RIVER DURING THIS PERIOD AND OTHER NEAR COASTAL RIVERS, THE DETAILS
OF WHICH WILL BE DETERMINED BY HOW MUCH THESE FRONTS STALL OVER ANY
ONE AREA. AT THIS TIME MINOR TO MODERATE FLOODING ON THE COQUILLE
APPEARS TO BE THE PRIMARY EXPECTED HYDROLOGICAL IMPACT. BTL
