AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MEDFORD OR
415 AM PDT FRI MAR 30 2012
.DISCUSSION...YET ANOTHER WET AND WINDY SYSTEM MOVES INTO THE
REGION AS THE TRANS-PACIFIC ATMOSPHERIC RIVER FLOWS DIRECTLY INTO
OUR AREA. SNOW LEVELS RISE AS WARM CONVEYOR FLOW BRINGS A STRONG
LOW LEVEL CONTRIBUTOR TO THE SATURATED MID LEVEL EXTRA- TROPICAL
FLOW. WINDS ON THE COAST ARE BORDERLINE HIGH WIND WARNING AND ARE
ONLY EXPECTED TO BRIEFLY RISE TO WARNING CRITERIA. HOWEVER...WITH
THE EXTREMELY AND DEEPLY SATURATED GROUND IN THAT AREA...THESE
WINDS SHOULD BE MORE THAN SUFFICIENT TO CAUSE FURTHER SCATTERED
TOPPLING OF TREES AND POWER OUTAGES. AS THE FRONT MOVES INLAND
THE GRADIENT TIGHTENS IN THE SHASTA VALLEY WITH STRONG WINDS
RESULTING AND 700 MB WINDS IN THE 60-70KT RANGE EAST OF THE
CASCADES WILL BRING WINDS BACK UP AFTER A SLIGHT LULL
TODAY..LASTING THROUGH SATURDAY AFTERNOON.
A MENTIONED ABOVE THERE IS A PERFECT COMBINATION OF STRONG
OROGRAPHIC LIFT WITH STRONG BL THROUGH 700 MB SOUTH TO SOUTHWEST
WINDS...STRONG UPPER LEVEL SUPPORT IN THE RIGHT ENTRANCE REGION OF
THE WESTERN JET COUPLET...AND GOOD MOISTURE INFLUX AT LOW LEVELS
INTO A SATURATED MID EXTRA-TROPICAL FLOW. SNOW LEVELS DROP TO
AROUND 3500 FEET TOWARDS THE TAIL END OF THE SYSTEM AS COOLER AIR
IS ENTRAINED INTO THE TRAILING EDGE OF THE WARM CONVEYOR FLOW.
&&
.AVIATION...MVFR DECKS WITH HIGHER TERRAIN OBSCURATION REMAIN
THROUGH THE NEXT 24 HOURS AS FRONT STALLS OVER THE REGION. STRONG
RIDGE LEVEL WINDS SHOULD PRODUCE TURBULENCE OVER MOUNTAINS THROUGH
THE NEXT SEVERAL DAYS.
