Arctic Air Mass Brings A Cold And Snowy Start to The New Year
ST. LOUIS (KSDK) - Our winter storm is is nothing if not prompt.
A strong arctic cold front arrived right on time, dropping temperatures twenty degrees or more in just a few hours and sending light to moderate snow into the area.
Now that the snow is here it will last through the night before lifting out to he east but it will leave behind 4-5" in St. Louis and north; 2-4" just south of St. Louis from southern Franklin county east to Carlyle Lake and 1-3" from Rolla to Farmington to Mt. Vernon, Ill.
As if that weren't enough lows will drop into the low teens by sunrise and winds chills between -5 and -10.
The National Weather Service issued a Winter Weather Advisory from 6 p.m. through 6 a.m. Thursday morning due to the expected snowfall.

Snow will work into our northwest counties by 7 p.m. and will spread into the St. Louis metropolitan area around 9 p.m. Heaviest snowfall will occur between 9 p.m. and 3 a.m.
The snow should exit our eastern counties fairly quickly Thursday morning. Two to 5 inches of snowfall is expected across the area with the heaviest totals along and north of the Interstate 70 corridor. Some spots could see totals of 5 or more inches.
The Southern third of the viewing area will see between 1-3 inches of accumulating snowfall.
A cold gusty north by northwest wind of 15 miles per hour, gusting up to 25 mph, Wednesday night will cause blowing snow across roadways and will reduce visibility.
The other side of this winter storm will be the very chilly temperatures. Lows will fall into the low 20s and teens with wind chills in the single digits to near 0 Wednesday night, and this will lead to very slippery road conditions.
