.SHORT TERM...TODAY THROUGH THURSDAY NIGHT...A PACIFIC SYSTEM WILL
MOVE THROUGH THROUGH THE PACIFIC NORTHWEST TODAY AND TONIGHT. THIS
SYSTEM WILL BRING VARIABLE AMOUNTS OF PRECIP TO THE REGION TODAY AND
TONIGHT. WINDS WILL INCREASE THIS AFTERNOON ACROSS MUCH OF THE AREA
WITH BREEZY TO WINDY CONDITIONS EXPECTED ACROSS THE COLUMBIA BASIN.
A PERIOD OF VERY WINDY CONDITIONS IS EXPECTED LATE AFTERNOON INTO

HEAVIER SHOWERS. SLOP OVER SHOWERS WILL PERSIST ALONG THE CASCADE
EAST SLOPES OVERNIGHT, WHILE UPSLOPE INDUCED SHOWERS WILL CONTINUE
OVER AND NEAR THE INTERIOR MOUNTAINS. SNOW LEVELS WILL LOWER TO

.LONG TERM...FRIDAY THROUGH WEDNESDAY...ON FRIDAY THE PACIFIC
NORTHWEST WILL BE ON THE EAST SIDE OF AN UPPER LEVEL RIDGE CENTERED
OUT IN THE EASTERN PACIFIC OCEAN. WE WILL BE IN A NORTHWEST FLOW
ALOFT WITH LITTLE IN THE WAY OF DISTURBANCES MOVING INTO THE AREA
THROUGH SATURDAY. IT SHOULD BE A PERIOD OF MOSTLY CLEAR SKIES, LIGHT
WINDS AND TEMPERATURES IN THE 50S WITH MID 40S TO LOWER 50S IN THE
MOUNTAINS. SATURDAY NIGHT A WEAK DISTURBANCE WILL MOVE OVER THE
RIDGE. THE GFS HAS IT PASSING TO OUR NORTH WHILE THE ECMWF IS A
LITTLE FURTHER SOUTH AND BRINGS A FEW LIGHT RAIN AND SNOW SHOWERS TO
THE WASHINGTON CASCADE CREST. HAVE LEANED TOWARDS THE ECMWF AND PUT
SHOWERS THERE WITH THE REST OF THE AREA DRY. MOST OF THE AREA WILL
JUST SEE A MILD INCREASE IN CLOUDINESS. ON SUNDAY AND SUNDAY NIGHT
THE RIDGE STRENGTHENS SHARPLY AS A STRONG SYSTEM APPROACHES OUT IN
THE PACIFIC. THE RIDGE WILL BE PUSHED OVER HEAD ON MONDAY AND THEN
OUT OF THE AREA TUESDAY. SUNDAY THROUGH MONDAY WILL BE ANOTHER DRY
PERIOD WITH TEMPERATURES WARMING TO THE UPPER 50S AND MID 60S WITH
MAINLY 50S IN THE MOUNTAINS. THE SYSTEM THAT IS PUSHING THE RIDGE
EASTWARD WILL ARRIVE EITHER TUESDAY OR WEDNESDAY DEPENDING ON THE
MODEL CONSULTED. GIVEN THE DIFFERENCES, HAVE A SLIGHT CHANCE OF
MAINLY RAIN SHOWERS OVER THE MOUNTAINS TUESDAY THEN A CHANCE OF
RAIN IN THE MOUNTAINS AND A SLIGHT CHANCE OF RAIN IN THE LOWER
ELEVATIONS TUESDAY NIGHT AND WEDNESDAY. TEMPERATURES WILL COOL A
COUPLE OF DEGREES FROM SUNDAY AND MONDAY BUT SNOW LEVELS WILL REMAIN
ABOVE 5500 FEET. PERRY
