THE RIDGE BEGINS TO BREAKDOWN LATE FRIDAY AFTERNOON WITH A

OF 60S TO LOW 70S EXPECTED. OVERNIGHT LOWS WILL DIP INTO THE

IN A WEAK PRESSURE PATTERN, SUPPORTING SCATTERED MOUNTAIN
SHOWERS AND BREEZY WINDS. TEMPERATURES WILL REBOUND INTO THE 70S
AND LOW 80S MONDAY THROUGH AS ANOTHER RIDGE BUILDS. THE RIDGE
IS EXPECTED TO WEAKEN BY WEDNESDAY EVENING AS A LOW PRESSURE
SYSTEM FROM THE GULF OF ALASKA APPROACHES. THE MODELS ARE
TRENDING DRIER AS THE SYSTEM IS EXPECTING TO STALL AND WEAKEN
BEFORE MOVING THROUGH THE PACIFIC NORTHWEST. IT IS LIMITING THE
CONFIDENCE IN PRECIP FOR THE MIDWEEK. THE SYSTEM WILL USHER IN A
COOLER SOUTHWEST FLOW PATTERN ALLOWING FOR HIGHS TO MODERATE
BACK INTO THE UPPER 60S AND 70S. OVERNIGHT LOWS WILL CONTINUE TO
BE IN THE UPPER 30S AND 40S. /JDC
