Time and Day: 0600 Thursday
The Snapshot: Snow has begun to fall at Steven Pass. Snow will continue through the day and taper
off to this evening. A few inches of
snow will be possible tomorrow afternoon. Winter storm advisory for the weekend.
The Science: A triple point low-pressure
system (a warm front, a cold front, and an
occluded front all connecting in the center) will bring pulses of snow
to Stevens Pass today. Once the cold
front passes east of the mountains this afternoon, the snow will taper to light
showers. Therefore, tonight will be
relatively quiet with little additional snow.
Another pulse of moisture tracking south of Stevens Pass tomorrow could
provide a few more inches before the big weekend game starts.
Long
Range: The game begins Saturday as
another strong triple point low-pressure
system approaches. Storm totals are
currently around 12-18” of snow by the end of the day on Sunday. More winter storms are starting to develop for
continued excitement next week.
