DES MOINES, Iowa (AP) — Iowans are preparing for another blast of frigid and dangerous winter weather this weekend. The National Weather Service has issued a winter weather advisory starting Saturday night in parts of eastern Iowa, and a blizzard watch for parts of northern and central Iowa into eastern Iowa on Sunday. Snow is expected in the northeast Saturday night. But by Sunday, strong winds of up to 50 mph are expected to create whiteout conditions in some areas.

Temperatures are also expected to plummet late Sunday, with lows coming in around 15-below zero in the northeast to near zero in southern Iowa. Wind chills of almost 50-below could hit some areas.
