The Snapshot: Light snow showers ending today. A
clearing trend begins this afternoon with extremely low temperatures for the
rest of the week.
The Science: Cold arctic air is currently streaming in from the northeast. The clouds, and thus the snow, will begin to
dissipate as the cold and dry air mass settles over the region. Warming trend begins on Friday.
4-7day Long Range: A low pressure system developing in the Gulf
of Alaska will bring rising freezing levels (+-4000’) and moisture to the PNW
during the weekend. Stay tuned as those
details develop.
