MOUNTAIN WEATHER FORECAST

Time and Day: 0900

The Snapshot:  Dry with mostly clear conditions will prevail through the weekend. Snow likely on Monday, dry and cold to end the Holiday week.  

The Science:  High pressure building over the Cascade Mountains will bring mostly dry and clear weather to the area for the weekend.  East/off-shore flow will keep the temperatures cool through tomorrow.  Warmer air aloft will invade tomorrow pushing freezing levels to near 5500’.  Therefore, expect a beautiful dry and relatively warm weekend. 

Long Range:  A cold front will descend south along the BC coast on Monday producing snow and low temperatures.  As of now, 4-8” of snow is possible from this storm.  Dry and cold arctic air moves in on Wednesday; Stevens Pass could see single digit low temperatures on Turkey day.

Today’s 24hr Water = 0   Snow =  0
