Thursday
The Snapshot: Mixed rain and snow today, rain turning to
snow tomorrow night, heavy snow expected on Saturday, then back to rain on Sunday.
Sporty.
The Science: Several fast moving frontal systems will move through
the PNW during the next 3-5 days. Waves
of moisture with freezing levels bouncing above and below 4500’ will be the game through the weekend. The winds will also be gusty as the fronts come and
go.
The first warm front
enters the mountains this afternoon with moderate rain showers; a cold front
follows tomorrow afternoon changing the rain to snow late tomorrow night or
early Saturday morning, moderate to
heavy snow is expected on Saturday with +8” possible.
The Long Range: Warm SW flow will push freezing
levels above 5000’ on Sunday with rain showers persisting into Tuesday.
