The Snapshot: “Let the games begin, and may luck
be always on our side.”
First, the UW Atmospheric Departmental web site is having an issue this
morning, so current forecast models are delayed. Light snow showers today with heavy snow
expected tomorrow.
The Science: The first in several progressively stronger
fronts will hit the PNW starting tomorrow.
Heavy snow expected tomorrow with freezing levels rising to 4000’. The next front hits on Tuesday with slightly
higher freezing levels and then another on Wednesday/Thursday.
4-7day Long Range: Storms will continue to pound the PNW
throughout the week. Rain is likely
below 4500’ on Wednesday. Long range
models are not available at this time so we will have to wait until tomorrow
for the most reliable information on the storms later in the week.
