A blizzard is developing in the Upper Midwest that could dump heavy snow and bring strong winds for many hours through Friday, forecasters say.

Blizzard warnings are in effect with up to 8 inches of snow expected for a widespread area. However, isolated amounts of higher totals can’t be ruled out.

Freezing rain will also be possible across the Upper Mississippi Valley. Traveling will be dangerous at the height of the storm with whiteout conditions, and power outages will also be a big concern, forecasters warn.
