SEATTLE — A cold weather advisory has been issued for early Sunday morning across much of western Washington, with overnight temperatures expected to fall into the low to mid 20s — and potentially the upper teens in some areas, forecasters said.

A weather alert was issued by the NWS Spokane WA on Saturday at 5:49 p.m. for strong thunderstorms until 6:15 p.m. for Washington Palouse.
