Winds will be strongest in the afternoon, with gusts closer to 35 mph. Temperatures will fall into the 20s by 3 p.m. Expect a few flurries and cloudy skies Monday afternoon and evening.

Arctic winds will continue into the night and throughout Tuesday. Overnight lows will fall toward 10°, with high temperatures in the 20s Tuesday. Sunny skies early will give way to afternoon clouds and a few snow showers in the bi-state. Another cold front moves in Tuesday, bringing yet colder weather—single digits below zero—Tuesday night.

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.
