Winter Storm Warnings Across Northern US
A big winter storm is happening in the northern part of the US.
It's bringing lots of snow, cold weather, and making it dangerous to drive in some places.
The storm started on Friday and will last through the weekend.
Places like Illinois, Michigan, Iowa, and Wisconsin might get a foot of snow.
The weather is also very cold, with temperatures in the 20s and 30s in the Midwest.
People traveling should be careful because of the snow and bad driving conditions.
Many flights have been canceled, especially in Chicago.
The governor of Iowa has asked everyone to be careful and follow safety guidelines.
The snow will be heaviest this afternoon and evening, so it's a good idea to stay home if you can.
Winter storm warnings are in effect from Montana to New York, with heavy snow expected in the Great Lakes and Midwest regions.
Up to a foot of snow is forecasted in parts of Illinois, Michigan, Iowa, and Wisconsin, with the highest rates around 1 inch per hour expected this afternoon into early evening (12-8pm CST).
Temperatures are significantly below average, with highs in the 20s and 30s in the Midwest.
Dangerous driving conditions are expected in eastern Iowa and northwestern Illinois due to snow squalls, with snow-covered roads and very low visibility.
