Time and Day: 0830 Friday
The Snapshot: Heavy rain and wind will be the game through late
Saturday night, snow possible on Sunday, dry and colder next week.
The Science: This morning’s radar is lit up with heavy rain
and high winds approaching Cascade Mountains. The leading edge of the
approaching warm front is expected to pass over the Cascade Crest around noon
or so today. Rain will intensify and
temperatures will rise with the passing of the front. The Puget Sound Convergence Zone will also
play a part in the precipitation and wind intensity tonight and tomorrow.
Sunday snow. Timing is everything.
Models are having a difficult time agreeing on the timing of the cold front expected
to swing through on Sunday. If freezing
levels begin to fall early Sunday morning, then Stevens could see over a foot
of snow on the ground Monday morning. The mountains above 5000’ could receive +-2’. Other models have the cold front passing the
over the mountains late Sunday afternoon/evening with rain turning to snow
later in the day. Either way, there
should be some snow left on the ground at or below 4000’ on Monday morning.
Long
Range: The action ends on Monday
with dry and cooler weather expected for most of next week.
