Time and Day: 9:30am Tuesday
The Snapshot: More snow tonight and tomorrow; dry, clear and cold
for Christmas day and the start of the weekend.
The Science: A cold front, pushed by strong NW flow, will bring
the next round of snow to the Cascade Mountains tonight and tomorrow. Snow showers will continue through Thursday morning
and taper off by the afternoon.
Long
Range: There will be a well-deserved break in the snow Friday and
Saturday as a high-pressure ridge drifts over
the region. Cold air sinking in from
Canada could bring single digit lows on Friday and then again on Saturday
morning.
