Wednesday could be one of the coldest day of 2019, with a high temperature in the single digits after our below 0° start. Wind chill temperatures will be brutal, as cold as -20°F for the metro St. Louis region. This will be dangerously cold weather, especially on Wednesday morning.

More single-digit temperatures are forecast Thursday morning, with milder 20s during the day.

Things are looking warmer by the end of the workweek, with forecast temperatures in the 40s to 50s for Friday and the weekend. There may be some rain showers late Sunday into Sunday night. Otherwise, the weekend will be partly sunny and mainly dry. We'll turn a little colder again next week.
