AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
914 AM PDT SAT APR 6 2013

.UPDATE...
AN UPDATE HAS BEEN MADE TO THE FORECAST FOR THIS AFTERNOON TO ADD
SOME SHORT TERM DETAIL TO THE PRECIPITATION PROBABILITY FORECAST
BASED ON HIGH RESOLUTION SHORT TERM GUIDANCE. THIS WAS TO INCREASE
POPS FROM THE OREGON CASCADES WESTWARD, WEST OF THE SISKIYOUS, AND
FROM THE MARBLE MOUNTAINS WESTWARD, AS WELL AS FROM THE TRINITY
ALPS EAST-NORTHEASTWARD TO THE MODOC HIGHLANDS. POPS HAVE BEEN
REDUCED SOME FOR THE USUALLY DRIER PORTIONS OF THE EAST SIDE AND
THE KLAMATH BASIN UPRIVER OF HAPPY CAMP.

&&

.DISCUSSION...
SHOWERS CONTINUE ACROSS THE AREA THIS MORNING, THOUGH CLOUD TOPS
ARE GENERALLY DIMINISHING. SHOWERS WILL END ACROSS MOST VALLEY
AREAS AWAY FROM THE COAST THIS MORNING WHERE THEY HAVE NOT
ALREADY. HOWEVER, THE NEXT WAVE OF LOW PRESSURE WITH A COLD TROUGH
AT MID AND UPPER LEVELS WILL GIVE RISE TO SHOWERS ACROSS MUCH OF
THE AREA THIS AFTERNOON.

A WARM FRONT WILL THEN PUSH IN THIS EVENING, FOLLOWED BY A COLD
FRONT ON SUNDAY AS A FAIRLY VIGOROUS LOW PRESSURE SYSTEM PUSHES
THROUGH. LATE SUNDAY AFTERNOON AND EVENING THE UPPER COLD CORE OF
THIS SYSTEM WILL MOVE ACROSS THE AREA PROVIDING POTENTIAL FOR
GUSTY WINDS, POTENT SHOWERS, SOME THUNDERSTORMS, AND FALLING SNOW
LEVELS. WE WILL SPEND THE DAY TODAY DETERMINING WHAT ADDITIONAL
HEADLINES AND ADJUSTMENTS MAY BE NEEDED FOR THIS VIGOROUS SYSTEM
DUE IN TONIGHT THROUGH TOMORROW.

&&

.AVIATION...
BASED ON THE 06/12Z TAF CYCLE.

ALONG THE SOUTHERN OREGON COAST...WIDESPREAD MVFR CIGS ARE EXPECTED
TODAY AND TONIGHT AS WELL AS AREAS OF IFR CIGS THIS MORNING AND
AGAIN THIS EVENING AND TONIGHT. INLAND VFR CONDITIONS ARE EXPECTED
WITH ISOLATED MVFR CIGS IN SHOWERS AND AREAS OF MOUNTAIN
OBSCURATIONS. A STRONG FRONT MOVES INLAND SATURDAY NIGHT. THIS FRONT
WILL BRING INCREASING PRECIPITATION AND WINDS. INLAND...AREAS OF
MVFR CIGS WILL DEVELOP AFTER 06Z WITH WIDESPREAD MOUNTAIN
OBSCURATIONS. LOW LEVEL WIND SHEAR IS POSSIBLE ALONG THE COAST AND
INTO THE UMPQUA BETWEEN 06Z AND 12Z.  ALSO GUSTY WINDS WILL DEVELOP
AHEAD OF THE FRONT LATE THIS EVENING INTO TONIGHT ALONG THE COAST
AND OVER THE MOUNTAINS.
/CC

&&

.PREV DISCUSSION... /ISSUED 408 AM PDT SAT APR 6 2013/

DISCUSSION...COOL...WET AND BREEZY TO WINDY WEATHER WILL AFFECT
OUR AREA INTO EARLY MONDAY MORNING THEN CLEARING MONDAY NIGHT WILL
LIKELY LEAD TO CHILLY TEMPERATURES ON TUESDAY MORNING.

A RELATIVELY WEAK COLD FRONT HAS REACHED THE SOUTHERN OREGON
CASCADES AND WESTERN SISKIYOU COUNTY AND IS PRODUCING MAINLY LIGHT
RAIN. THE FRONT SHOULD EXIT EAST OF LAKE AND MODOC COUNTIES IN THE
AFTERNOON. BEHIND THE FRONT, THERE WILL BE OCCASIONAL LIGHT
SHOWERS WITH A WEAK SHORTWAVE OR TWO EMBEDDED IN THE MOIST
WESTERLY FLOW ALOFT. SO, SOME PERIODS OF RAIN BUT ALSO SOME BREAKS
OF SUN THROUGH THE CLOUDS.

CONDITIONS WILL DETERIORATE TONIGHT. A MUCH STRONGER COLD FRONT
..PRESENTLY NEAR 40N 140W...IS EXPECTED TO REACH THE COAST LATE
IN THE EVENING...REACH THE CASCADES BY EARLY SUNDAY MORNING THEN
REACH EASTERN OREGON BY NOON. PRECIPITATION AMOUNTS SATURDAY NIGHT
THROUGH SUNDAY WILL BE SIGNIFICANT BUT THE MOST IMPORTANT ASPECTS
OF THIS STORM WILL BE GUSTY SOUTHWEST TO WEST WINDS AND LOWERING
SNOW LEVELS TO THE MOUNTAIN PASSES. WINDS WILL BE STRONGEST ON THE
EAST SIDE...ESPECIALLY IN LAKE COUNTY. THE 00Z GFS AND 00Z NAM
EACH SHOW A 700 MB WESTERLY JET OF 60 KT OVER LAKE COUNTY SUNDAY
MORNING AND THAT IS A GOOD RULE OF THUMB FOR THE STRONGEST GUSTS
THAT WILL OCCUR IN THE VICINITY OF SILVER LAKE AND SUMMER LAKE.
I SHORTENED THE HIGH WIND WATCH FOR SOUTH CENTRAL OREGON BY 3 HOURS
TO END AT 8 PM AS THERE IS GOOD MODEL AGREEMENT ON WINDS
DIMINISHING SUNDAY EVENING.

RAIN IS EXPECTED TO CHANGE TO SNOW ON MANY OF THE MAJOR PASSES
SUNDAY MORNING INCLUDING AT DIAMOND LAKE JUNCTION, LAKE OF THE
WOODS ON HIGHWAY 140 AND SISKIYOU SUMMIT ON I-5. SNOW LEVELS ARE
STILL EXPECTED AT 5000 TO 5500 FEET SATURDAY NIGHT THEN FALLING TO
AROUND 3500 TO 4500 FEET SUNDAY. IT IS SO LATE IN THE YEAR AND
ROADWAY TEMPERATURES HAVE RECENTLY GOTTEN SO VERY WARM THAT IT
WILL BE INTERESTING TO SEE HOW LONG IT TAKES BEFORE SNOW BEGINS TO
STICK ON ROADWAYS. IT WILL DEFINITELY BE A BAD TIME TO BE OUT AND
ABOUT IN THE HIGH COUNTRY.

THE SNOW LEVEL WILL CONTINUE TO DROP SUNDAY NIGHT INTO MONDAY
MORNING AS THE UPPER LEVEL TROUGH MOVES INTO AND ACROSS THE
PACIFIC NORTHWEST WITH ADDITIONAL SHORTWAVE DISTURBANCES. THESE
SHOWERS AND SNOW SHOWERS WILL BE GRADUALLY DECREASING IN COVERAGE
AND INTENSITY. ELEVATIONS AS LOW AS 2500 FEET COULD SEE A LITTLE
SNOW LATE SUNDAY NIGHT/EARLY MONDAY MORNING. DESPITE THE COLD AIR,
LINGERING CLOUD COVER SHOULD PREVENT ANYTHING MORE THAN ISOLATED WEST
SIDE FROST ON MONDAY MORNING.

IT WILL LIKELY BE A DIFFERENT STORY ON TUESDAY MORNING. HIGH
PRESSURE OFFSHORE ON MONDAY WILL NUDGE INTO THE PACIFIC NORTHWEST
WITH A DRYING AIR MASS AND DECREASE IN CLOUD COVER BUT ALSO A
CONTINUED COLD NORTHERLY FLOW. THE 00Z GFS INDICATES A VERY WEAK
INVERSION WILL BE PRESENT. LOWS ON THE WEST SIDE WILL BE MAINLY IN
THE 30S AND MAINLY IN THE 20S ON THE EAST SIDE.

WARMING WILL BE NOTICEABLE DURING THE DAY ON TUESDAY THEN THE
RIDGE WILL LINGER WITH A WARMER AIR MASS TUESDAY NIGHT INTO
WEDNESDAY.

MODEL DIFFERENCES INCREASE WEDNESDAY AFTERNOON WITH UNCERTAINTY
IN THE SOUTHERN EXTENT OF THE TRACK AND STRENGTH OF A COLD FRONT.
THIS SYSTEM IS VERY LIKELY TO AT LEAST AFFECT WASHINGTON AND
FLATTEN THE RIDGE OVER THE WEST COAST. THE FRONT IS EXPECTED TO
REMAIN OFFSHORE THROUGH THE AFTERNOON THEN FOR WEDNESDAY NIGHT THE
PROBABILITY OF MEASUREABLE RAIN IN OUR AREA IS HIGHER AS ONE GOES
TO THE WEST AND NORTH. THE MOST LIKELY SCENARIO IS A PERIOD OF
BRIEF VERY LIGHT RAIN CONFINED TO SOUTHWEST OREGON AND NORTHWARD
WEDNESDAY NIGHT.

A SHORTWAVE RIDGE IS EXPECTED THURSDAY BUT THE WETTER 00Z GFS
SUPPORTS A MENTION OF A SLIGHT CHANCE OF VERY LIGHT OVERRUNNING
SHOWERS NORTH OF THE UMPQUA DIVIDE. THIS WEAK RIDGING IS LIKELY TO
PERSIST THURSDAY NIGHT INTO FRIDAY. UNCERTAINTY IS VERY HIGH WITH
THE STRENGTH AND TRACK OF ANOTHER COLD FRONT LATE IN THE WEEK.

AVIATION...
BASED ON THE 06/06Z TAF CYCLE.

OCCASIONAL MVFR CIGS ARE EXPECTED AT THE COAST THROUGH THE EARLY
MORNING. ALSO, AREAS OF MVFR WITH MOUNTAIN OBSCURATIONS IN THE UMPQUA
BASIN AND POSSIBLY THE ROGUE VALLEY AS A COLD FRONT APPROACHES.
MVFR CIGS ARE EXPECTED TO PERSIST THROUGH MOST OF THIS MORNING. WIND
SPEED SHEAR COULD DEVELOP AT KRBG. FOR NOW NOT EXPECTING WIND
SPEED SHEAR TO BE AN ISSUE IN THE ROGUE VALLEY...BUT WILL NEED TO
BE WATCHED CLOSELY. GUSTY WINDS WILL DEVELOP LATE THIS AFTERNOON
AND THIS EVENING AHEAD OF THE FRONT...ESPECIALLY ALONG THE COAST
AND OVER THE MOUNTAINS.
