DISCUSSION
WITH A BIT OF NORTHERLY FLOW ALOFT, WE MANAGED TO CLEAR OUT
ACROSS THE REGION TODAY AND THE SUN ACTUALLY MADE AN APPEARANCE
FOR THE FIRST TIME IN AWHILE. HOWEVER, THE SUN WILL BE SHORT LIVED
AS THE RIDGE WILL RE-ESTABLISH ITSELF OVER THE COURSE OF THE
COMING WEEK.
HIGH PRESSURE WILL BUILD BACK OVER THE REGION BEGINNING ON SUNDAY.
HOWEVER, A WEAK TROUGH WILL THEN MOVE OVER THE PACIFIC NORTHWEST
ON MONDAY. THIS TROUGH SHOULD BRING NOTHING MORE THAN SLIGHT
CHANCE POPS (20 PERCENT) FOR THE CASCADES. THE HIGH THEN REBUILDS
(ALONG WITH FOG AND STRATUS CHANCES) THROUGH MIDWEEK. A SERIES OF
WEAK SYSTEMS WILL AFFECT MAINLY THE MOUNTAINS BEYOND MIDWEEK, THAT
WILL BREAK DOWN THE RIDGE AND THEN BUILD IT RIGHT BACK UP AGAIN.
HOW MUCH IMPACT THESE SYSTEMS WILL HAVE ON DECREASING THE FOG AND
STRATUS REMAINS TO BE SEEN. ULTIMATELY, TEMPERATURES WILL BE
BASED ON THE STRATUS RETURNING. IF WE RETURN TO BEING
CLOUDED/FOGGED IN TEMPERATURES WILL BE BELOW NORMAL. IF WE EVEN
GET SOME BREAKS ON SOME DAYS, TEMPERATURES WILL BE CLOSER TO
NORMAL.
