Cold enough for you?

You'll be able to chill the New Year's champagne just by carrying it outside today and tonight.

But if you’re going any farther than the backyard, be careful. Driving conditions are going to be tricky.

Some updates:

Weather forecast: Sunny and cold. The National Weather Service says it’s not likely to get much above 40 degrees anywhere in the Puget Sound area for at least the next three days.

Nighttime lows are forecast to be in the low 20s and high teens. Clear skies are expected today. Saturday, Sunday and Monday will be partly cloudy.

Driving: Take it easy. Freezing nighttime weather is likely to leave roads slick in places, particularly on bridges and overpasses, on steep grades and on pavements that are not dry. Travelers can get more information by calling 511.

Cascades: Mostly sunny, clear and cold. A light wind – 10-15 mph – is expected in the passes.
