NWS Medford, OR wrote its last area forecast discussion before this river flood watch went out at Mar 27, 2:48 PM PDT, 2 hours 31 minutes earlier.

Area forecast discussion, Mar 27, 2:48 PM PDT, 2 hours 31 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
248 PM PDT TUE MAR 27 2012

.SHORT TERM...STRONG SOUTHERLY FLOW WITH VERY STRONG WINDS ON THE
RIDGES. OCCLUDED FRONT HAS MOVED ONSHORE AND WILL SLOWLY MOVE
EASTWARD ACROSS THE FORECAST AREA TONIGHT. WINDS WILL DECREASE
BEHIND THIS FRONT. AREAS WHERE HIGH WIND WARNINGS HAVE BEEN POSTED
SHOULD SEE WINDS DIMINISH BELOW WARNING CRITERIA AFTER THIS FRONT PASSES.

HEAVY SNOW IN SISKIYOU COUNTY CALIFORNIA AT ELEVATIONS ABOVE 4500
FEET WILL CONTINUE THROUGH EARLY WEDNESDAY MORNING. HEAVY SNOW
WILL FALL AT LOWER ELEVATIONS AROUND THE MOUNT SHASTA AREA DOWN TO
3000 FEET BUT ACCUMULATIONS WILL VARY WIDELY DUE TO WET SNOW
CONSISTENCY.

PRECIPITATION WILL BECOME SHOWERY WEDNESDAY AFTER SUNRISE AS THE
TROF AXIS MOVES THROUGH SOUTHERN OREGON AND NORTHERN CALIFORNIA.
STILL...NORTHERN CALIFORNIA SHOULD SEE THE BULK OF THE SHOWER
ACTIVITY. A SHORT BREAK FROM THIS STORMY PATTERN WILL OCCUR
WEDNESDAY NIGHT INTO EARLY THURSDAY. A VERY SHORT BREAK INDEED AS
THE NEXT VERY MOIST SYSTEM MOVES ONTO THE SOUTH OREGON COAST
THURSDAY MORNING. SNOW LEVELS RISE WITH THIS SYSTEM AND RAPID
RIVER RISES IN COOS AND CURRY COUNTIES ARE LIKELY THURSDAY NIGHT
AND FRIDAY.

.LONG TERM...FRIDAY TO TUESDAY...THE HITS KEEP COMING AS AN
ATMOSPHERIC RIVER EVENT IS LIKELY TO BE UNDERWAY BY FRIDAY MORNING.
MODELS SHOW A GOOD FETCH OF 1 INCH+ PRECIPITABLE WATER VALUES
STRETCHING INTO SOUTHWESTERN OREGON FRIDAY INTO FRIDAY NIGHT.
ADDITIONALLY...AN ACTIVE MJO IN THE PACIFIC BASIN IS PROVIDING A
GENERALLY GOOD ENVIRONMENT FOR INCREASED DYNAMICS AND MOISTURE FEED
INTO OUR REGION. THEREFORE...EXPECT A WET FRIDAY WITH COASTAL BASIN
RIVERS RESPONDING TO HEAVY RAIN...AND HAVE BUMPED UP QPF VALUES IN
CURRY AND WESTERN JOSEPHINE COUNTY BY AT LEAST 25 PERCENT BASED ON
FAVORABLE FLOW NORMAL TO THE COASTAL TERRAIN AND HIGH MOISTURE.

LOW PRESSURE THAT DEEPENS OFF THE COAST WILL ROLL THROUGH THE REGION
SATURDAY...INCREASING WINDS ACROSS THE AREA AND SPREADING
PRECIPITATION INTO THE EAST SIDE. THE ECMWF AND GFS ARE IN AGREEMENT
WITH THIS FEATURE...BUT DIFFER SOME ON THE STRENGTH. WILL NEED TO
MONITOR FUTURE MODEL OUTPUT FOR A POSSIBLE SIGNIFICANT WIND EVENT
FOR THE COAST AND ESPECIALLY EAST OF THE CASCADES. SUNDAY REPRESENTS
A GENERAL BREAK IN THE ACTIVE WEATHER WITH SOME DRYING AS A FRONT
NEARS THE COASTAL WATER. THE EC AND GFS DIFFER SHARPLY ON THE
EVOLUTION OF THE PATTER MONDAY AND TUESDAY...WITH THE GFS SUGGESTING
MORE HEAVY PRECIPITATION AND THE ECMWF DRIER. THE FORECAST REFLECTS
ABOVE NORMAL CHANCES OF PRECIPITATION THROUGH TUESDAY.

&&

.AVIATION...THE MAIN IMPACT WILL BE GUSTY SOUTH TO SOUTHWEST WINDS
THROUGH EARLY THIS EVENING WHICH WILL RESULT IN MODERATE TO
SEVERE TURBULENCE. THERE IS ALSO A CONCERN FOR WIND SPEED SHEAR IN
THE UMPQUA BASIN AND ROGUE VALLEY THROUGH THIS EVENING. VFR TO MVFR
CONDITIONS SHOULD PREVAIL IN THE VALLEYS NORTH OF THE SISKIYOUS
TONIGHT EVEN AS THE FRONT MOVES INLAND. IFR WITH LOCAL VLIFR
CONDITIONS ARE EXPECTED SOUTH OF THE SISKIYOUS WITH AN UPSLOPE
SOUTH FLOW. MOUNTAINS WILL REMAIN OBSCURED THROUGH TONIGHT...WITH
THE MOST IMPACT OVER NORTHERN CALIFORNIA AND THE SISKIYOUS OF
SOUTHWEST OREGON.
