0630 Tuesday:
The Snapshot: It’s nice to see a little of
the white stuff. Light snow showers are
expected for the next three days with just an inch or two possible each day. Snow on Friday/Saturday, rain on Sunday.
The Science: A low-pressure system makings its way through Oregon
will spin bands of moisture up along the foothills of the Cascades for the next
few days. Cool air trapped in the
eastern basin will continue to influence freezing levels at the Pass. A frontal system will make its way on shore
late Thursday night. This will bring
some measurable precipitation on Friday with the potential of 4-6” of snow on
the ground by Saturday morning.
4-7day
Long Range: A strong SW oriented
frontal system is expected to hit Saturday night. As of now, heavy snow with a potential of a
foot or more is possible Saturday night, freezing levels rise to +-7k on Sunday
with heavy rain. The precipitation
changes back to snow on Monday and tapers off during the first half of the
week. Models still disagree on the
timing and specific details; so stay tuned a usual.
