Time and Day: 0600 Tuesday
The Snapshot: Its currently 380, windy, with almost .75”
of rain that has fallen since midnight… Wind and rain will continue today, mixed rain
and snow tomorrow; off and on snow for the remainder of the week.
The Science: Strong south-westerly flow will produce high winds,
high freezing levels and heavy rain at Stevens Pass today. The snow pack will begin to rebuild tomorrow as
a low-pressure system developing off shore drives more winterish storms into the
PNW. The rain changing back to snow game
will start tomorrow and last through the weekend.
Long
Range: High pressure building early next week will
bring drier weather with temperatures
near seasonal norms. (colder)
