Time and Day: 10:30 am Wednesday
The Snapshot: Steady snow will continue through tomorrow morning. Intermittent snow shower can be expected to
linger into Christmas day.
The Science: A low-pressure
system slowly drifting east will keep the snow pumping through tomorrow morning. The atmosphere will remain unstable under
cool NW flow into Christmas Day, keeping snow showers with clear periods possible.
Long
Range: The overall pattern begins to change on Friday
as a high-pressure ridge builds along the
PNW coast. The weekend will be dry and
partly clear.
