Time and Day: 0630 Saturday
The Snapshot: Light snow showers with sun
breaks today, snow tomorrow and Monday. More winter storms next week.
The Science: This morning’s radar has
bands of snow showers moving NE through the state. A weak upper level ridge coupled with an
unstable atmosphere will keep intermittent snow showers with breaks in the
clouds today.
Clouds thicken tonight as the next system begins its approach. This system is timing out to reach the Cascade
Crest early tomorrow morning (4am ish). East
flow will briefly develop tonight then shift westerly with the passing of the
front. This storm has a more westerly flow effect than the last, so expect the wind
and The Puget Sound Convergence Zone to have some influence. The snow will continue Monday pushed by yet
another low pressure system.
Long
Range: The storms keep rolling in
through the middle of next week with more significant snow. There is a potential to have 2 or even 3 more
feet of additional snow pack by Christmas day.
