The National Weather Service reports winter weather is returning across Missouri with snow and sleet into Sunday morning. A Winter Weather Advisory is in effect until 6 a.m. Sunday.
Following an unseasonably warm Friday, a strong cold front moved southeast across the state Saturday, sending temperatures falling into the 30s.
Meanwhile, a weak area of low pressure developed along the front to the southwest and brought moisture back north up and over the cold dome of air.
Rain is expected to change to sleet and snow before ending, with minor sleet and snow accumulations possible along and north of I-44 in Missouri and I-70 in Illinois. This could cause hazardous driving conditions on untreated roads.
