Time and Day: 0800 Thursday
The Snapshot: Rain diminishes to scattered showers today, high
winds and heavy rain begins tomorrow and continues through Sunday. There may be a few inches of snow left on the
ground for the Monday commute. Dry
and cold next week.
The Science: The games
begin tomorrow morning when the first of several closely packed fronts plow into
the Cascade Mountains. The winds will
strengthen today as the pressure drops and gradients tighten. The first warm
front is scheduled to arrive early tomorrow morning with strong westerly flow
and heavy rain. Another front from the SW joins the action Saturday evening intensifying
the rain even further. Then on Sunday a cold front swings through from the NW
dropping freezing levels to +-4000’ and possibly leaving a few inches of snow
by early Monday morning.
Long
Range: Monday – Thursday of next week will be dry
and mostly clear under cool northerly flow.
Low temperatures could dip into the low to middle 20’early next
week. Good snowmaking weather.
