An arctic front will move into mid-Missouri Saturday afternoon bringing snow and bitter cold air to the region. Snow will develop through the afternoon north of I-70, spreading south through the evening. Temperatures will fall into the 20s by evening.

At the same time, a developing storm system will track to our south, heading into the mid-Mississippi valley overnight Saturday.  A band of moderate to heavy snow on the backside of this storm system will develop in areas south and east of HWY 54 into southeastern Missouri, continuing into early Sunday before moving to the east.

Snowfall amounts will be lower to the northwest and higher toward the east and south. Most of mid-Missouri will receive 2-4 inches of snow with higher amounts of 5-7 inches from the Lake of the Ozarks eastward. Visibilities will be reduced late Saturday night into Sunday from blowing and drifting snow as northerly winds increase.

Bitter cold air, the coldest since the 1980s, moves in Sunday. Temperatures will only reach the lower teens before falling in the afternoon through evening. Low temperatures will drop to -5 to -10 early Monday morning with dangerous wind chill readings from 20 to 30 below zero. Highs will only reach near zero Monday afternoon.

Travelers are urged to use caution Saturday night as the snow increases. Travel to the east or south will become treacherous in the heavier snow overnight Saturday into early Sunday. Slick roads are expected across all of mid-Missouri from Saturday evening through Sunday due to snow covered roads.
