Northwest Oregon and southwest Washington will see cool
temperatures tonight, with overnight lows into the lower to middle
30s. This will be cold enough to support patchy frost developing
across the interior lowlands.

A system will push even colder air into the area late Friday
night into Saturday, which will bring rain to lowland areas. Snow
levels will lower to around 1500 feet, with minor accumulations
above that point. As this system passes, skies will clear later
Saturday. Expect freezing temperatures this weekend, with
overnight temperatures from the upper 20s to middle 30s across
lower elevations. This will result in widespread frost, Saturday
night into Sunday morning, and again Sunday night into Monday
morning across much of northwest Oregon and southwest Washington.

Now is a good time to pick your remaining vegetables and to cover
other frost sensitive plants. It is also a good time to winterize
your outdoor pipes and hoses for the upcoming winter.
