An upper level wave over the High Plains Sunday night is working its way southeast giving us a mixed bag of precipitation overnight into Monday morning.
There will be a defined cutoff between precipitation types as we approach early Monday morning.
Much of mid-Missouri will see rain after midnight, more likely after 2 a.m. Depending on surface temperatures, cities along and north of I-70, near US 54 between Jefferson city through Louisiana, MO, and US 63 from Jefferson City to north of Kirksville will see a glaze of ice up to 0.2" of accumulation.
A freezing rain advisory is in effect from midnight to noon on Monday for Audrain, Boone, Callaway, Chariton, Howard, Montgomery, and Randolph counties.
If temperatures dip below 32, expect to encounter slippery spots on local and state roads.
Precipitation will continue through the late morning hours and end by around noon. Some areas north of I-70 could see some lingering flurries as the system continues on to the east.
Highs will reach the low to middle 40s Monday, with warmer temperatures further south, especially for the lake area.
Clouds decrease Monday night, giving way to warmer air and mostly sunny skies on Tuesday.
