The St. Louis metropolitan area is under a wind chill advisory until noon Thursday, according to the National Weather Service.
Overnight temperatures dipped to a low of 2 degrees in the metro-east. But with strong winds of up to 25 miles an hour in the area, the wind chill made it seem like the temperature was 19 below zero.
According to the National Weather Service forecast, the temperature will only warm to 3 by 9 a.m. Thursday with a wind chill of 15 degrees below. The high will eventually climb to a high of 10 by the afternoon.
Weather forecasters warned people to stay inside if they can. If they must go out during the wind chill advisory, people should dress in several layers to stay warm. Only a few minutes of exposure to the dangerously cold temperatures could result in frostbite.
