LONG TERM /SUNDAY THROUGH THURSDAY/
ABOVE NORMAL TEMPERATURES WILL PERSIST TO START THE LONG-TERM
PERIOD, AS SOUTHERLY FLOW BEGINS TO VEER MORE WESTERLY AS THE
UPPER LEVEL RIDGE SHIFTS EAST. THIS IS IN ADVANCE OF A TROUGH
THAT WILL DIG DOWN FROM THE BRITISH COLOMBIA COAST AND SWING THE
AREA INTO AN UNSETTLED PATTERN. TEMPERATURES BOTH SUNDAY AND
MONDAY WILL BE 10-15 DEGREES ABOVE NORMAL.
COME LATE MONDAY/EARLY TUESDAY, THE AFOREMENTIONED TROUGH AND
IT'S ASSOCIATED COLD FRONT WILL CROSS OVER THE PACIFIC
NORTHWEST. THIS WILL ACT TO INCREASE PRECIPITATION CHANCES,
BRING BREEZY TO GUSTY WINDS, AND COOL TEMPERATURES DOWN NEAR
NORMAL. PRECIPITATION CHANCES WILL INCREASE THROUGH MONDAY
AFTERNOON, INITIALLY OVER HIGHER TERRAIN, BEFORE REACHING 40-80%
AREA-WIDE TUESDAY. THE UNSETTLED PATTERN WILL CONTINUE THROUGH
THE WEEK WITH EMBEDDED SHORT-WAVES WITHIN THE GENERAL TROUGHING
ALOFT. COME LATE WEEK, THERE IS GOOD CONSENSUS ON ANOTHER LOW
DIGGING DOWN THE COAST OF BRITISH COLUMBIA INTO OUR AREA, THIS
WILL INCREASE PRECIPITATION CHANCES TO 50-90% AREA-WIDE COME
THURSDAY AFTERNOON. WITH COOLER TEMPS AND LOWER SNOW LEVELS,
HIGHER ELEVATIONS WILL LIKELY SEE SOME SNOW ACCUMULATION.
