Arctic air blowing into the Inland Northwest prompted the National Weather Service to issue a wind chill warning for the Spokane region for Wednesday morning.
Forecasters expect temperatures around zero with 10 mph to 20 mph winds, which could create a wind chill of 20 below -- enough to freeze exposed skin.
Forecasters also say cold temperatures could set records in Western Washington between Wednesday and Friday. Highs Wednesday -- when the Seahawks parade in Seattle -- and Thursday are forecast in the 30s. Seattle's record low maximum for Feb. 5 is 34 (1989) and Feb. 6 is 37 (1949).
The Weather Service says the cold should start to ease by the weekend when precipitation arrives, probably starting as snow. Forecasters say temperatures should return to normal next week.
