Millions of people will hit the road this Thanksgiving. Drivers in the St. Louis region may see rain in the next two days, and there’s a chance of snow in Illinois.

There have been 184 tornado warnings in Missouri in 2024, which is the third-highest number on record.

The windchill could hit 10 to 15 degrees below zero Fahrenheit on Sunday and Monday. In those conditions, frostbite can occur in 30 minutes and hypothermia can set in quickly.

The year in St. Louis’ climate was defined by nights that wouldn’t cool down and a record-setting lack of rain.

Meteorologists expect dangerous heat to stick around for at least another day. Experts urge people to stay indoors if possible.

Even when skies are clear, air pollution can affect the health of sensitive groups.

A sudden dust storm caused low visibility conditions that led to 72 vehicles colliding on Interstate 55 in Illinois on May 1. Seven people died, and 37 others were injured.

While the Mississippi River produced major flooding in parts of northern Illinois, Wisconsin, Iowa and Minnesota, it is expected to crest well below serious flood levels in the St. Louis area this weekend.

Many cities in the Upper Midwest have seen the river already reach its crest, as the water moves down through the system.

States in the Midwest and South have already seen many deadly tornadoes so far this year. These parts of the country are also where the number of severe events are steadily increasing.
