Winter Storm Tonight through Sunday

A major winter storm system is expected to bring measurable snow to much of the region tonight and continue through much of the day Sunday. Precipitation may initially begin as rain and/or sleet across portions of southeast Missouri and southern Illinois, but this should change over to snow by late tonight as the cold air rushes into the region. While it is still early, the latest indications are that significant snow accumulations will be possible across much of central and eastern Missouri as well as southwest and southern Illinois where 6-10 inches is becoming increasingly likely. After the snowfall, a bitterly cold Arctic air mass will settle across the region. Some uncertainty remains regarding the exact numbers, but this may be the coldest temperatures much of the region has seen in nearly 20 years. Low temperatures are expected to drop at or below zero across much of the area both Monday and Tuesday morning. High temperatures on Monday are expected to remain below zero across along and north of the interstate 70 corridor, while remaining in the single digits across the remainder of the area. Strong northwesterly winds are expected to create dangerous wind chill values ranging from -15 to -35 degrees late Sunday night through Tuesday morning. The coldest readings will likely be across portions of northeast Missouri and west-central Illinois.
