A winter storm is bringing between 2 and 4 inches of snow to most of the state, with as much as 5 inches expected to fall between Columbia and the St. Louis area.

Meteorologist-in-Charge Wes Browning with the National Weather Service’s St. Louis office says that’s where the system will be the most, “wound up … the snow will be heaviest probably between 10 p.m. and about 6 a.m. in the St. Louis area.”

Behind that storm is a cold air mass that will leave temperatures significantly colder tomorrow, but another one is on the way that will be colder still.

“Sunday into Monday there is possibly a historic arctic outbreak that’s going to come down,” Browning says, “It could actually bring us the coldest temperatures we’ve seen in 15 years in parts of the state. Places like St. Louis may actually go below zero (for overnight lows) and we haven’t done that in 15 years.”

Another storm could also bring significant snowfall to Missouri Sunday.

Browning says it’s too early to tell how much snow could fall, but Missourians will want to be watching developments, “Especially if they’re travelling. If you’re travelling this weekend you’ll want to keep in tune to later forecasts.”
