Time and Day: 0630 Monday
The Snapshot: Increasing mixed rain and snow today with temperature
inching up. Heavy rain and high winds
are still on the menu for tonight and tomorrow.
The Science: As luck would have it, the storm sagged just south
of Stevens Pass and with it, the bulk of the warmer air. Steven received 6” of new snow last night. Currently,
there is very light snow showers with partially clear skies and temperatures at
320 .
A warm front is expected to lift north today with increasing mixed rain
and snow below 4500”. Another, yet
stronger, warm front will follow tonight with strong winds and higher freezing levels. Heavy rain is expected through most of
tomorrow with a cold front entering the scene late tomorrow night possible
changing the rain back to snow on Wednesday – more on that later today.
Long
Range: The active storms track will continue this
week with freezing levels bouncing between 3500’ and 4500’starting Wednesday. If luck remains with us, Stevens Pass could
weather the rain event well and have an additional foot or more snow on the
ground by the upcoming weekend.
