Time and Day: 0630
Friday
The Snapshot: 21degrees
with 3” of new snow this morning. Snow continues today with the Holiday weekend
trending dry and clear. Another winter storm
is in the works for Monday night and Tuesday.
The Science: A low-pressure
system that has formed off the Washington coast will track NE through the state
today. This will provide steady snow and
cool temperatures for the next +-24hrs. The snow ends early tomorrow morning as the
flow splits around a high pressure ridge.
The weekend will be mostly dry with clear periods and cold air settling
into the eastern basin.
The Long Range: A strong warm front will bring another round
of moderate to heavy snow and a spike in freezing levels Monday night. Cool unstable flow fills in on Tuesday with snow
likely falling into early Wednesday morning.
