...Heavy mountain snow and possible low land snow Tonight into
.A strong cold front will move through southern Oregon and
northern California today. As cold air pours in behind the front
tonight, snow levels will drop rapidly to around 1500 feet. Snow
levels will then fluctuate between 1500 and 2500 feet, highest
during Friday afternoon.
At the same time, a rich plume of Pacific moisture will take aim
at the area, and the result will be very heavy snow in the
mountains. Particularly hard hit will be the mountains of Curry,
Josephine, and western Siskiyou counties where several feet of
snow are possible. Heavy snow is also expected over the Cascades,
Mt. Shasta area, and portions of the east side, although
confidence in snow amounts is lower for these areas.
Snow may also impact lower elevations at times, especially at
night and especially the more snow-prone areas like the I-
5 Passes north of Grants Pass and the Illinois Valley.
