We’ve got a cold night on the way as the clouds continue to clear. Overnight night lows will be in the low to mid 20s across western Oregon. That means meltwater, slush and snow will freeze, creating slick spots on western Oregon roads. Drive carefully.

Keep that idea in mind for Tuesday afternoon, too. A new batch of snow is on the way.

A Winter Weather Advisory is up for the Willamette Valley and southwest Washington beginning at 4 pm Tuesday.

Snow may begin earlier in the day, but it really picks up during the afternoon and evening commute.

The Portland and Vancouver area will likely see 1 to 3 inches of new snow, with more in the hills and the Cascade and Coast Range foothills.

This round of snow will end early Wednesday morning. Wednesday will be partly sunny and cold again, with valley highs near 40-degrees.

We’ve got a couple more snow chances on the way later in the week.

Thursday will likely bring a rain snow shower mix, but little if any accumulation.

A stronger storm brings valley rain and mountain snow Friday night and Saturday. Behind it, snow showers may again reach the valley floor on Sunday.

The cold, occasionally wet weather pattern with low snow levels is likely to continue into next week.

Enjoy the snow.
