More arctic temperatures are arriving across the Inland Northwest on northerly gusty winds that could cause drifting snow.
Plow crews were working their way from major routes and moving through secondary routes, hilly locations and residential areas after a half foot of snow fell from Saturday night into Tuesday morning.
The National Weather Service has advisories posted through 10 a.m. Wednesday for blustery north winds.
Lows are expected to drop to single digits from Wednesday through Friday nights before moderating temperatures move in for the weekend.
Forecasters said snow, then rain, are possible Sunday through Tuesday with the rain coming on Monday and Tuesday when highs get to the lower 30s. They said the forecast could change as the weekend arrives.
