ST. LOUIS (KSDK) – The St. Louis metropolitan region is bracing for what could be the coldest night in two years.

A blast of arctic air, along with a clearing sky, will help lead to the chilly night for our region. The predicted low is expected to range from 0 to about 10 degrees across our part of Missouri and Illinois.

The last time Lambert-St. Louis International Airport reported single digits Feb. 1. That morning the airport recorded 9 degrees.

Tonight's forecast is calling for single digit temperatures with a light breeze, wind chill temperatures will be a little below 0.

St. Louisans will wake up to a clear sky Tuesday and very cold conditions. A modest warm-up is expected for Christmas Eve before temperatures rebound to above freezing for Christmas Day.
