The little bit of snow and ice that cities in the metro-east got Monday afternoon was already melted by nighttime, but that might change going into Tuesday morning.
The National Weather Service cleared a winter weather advisory that had been issued for parts of Illinois and Missouri on Monday that included St. Clair, Madison, Randolph and Monroe counties and St. Louis. All the advisories ended at 9 p.m. Monday except for the one in Randolph County, which is in effect until 2 a.m. Tuesday and included patchy freezing drizzle with a light glaze of ice possible.
A hazardous weather warning was still in place for the overnight hours, however, with an additional half an inch to an inch of snow possible before 1 a.m. The warning also said very light glazing was possible for parts of Southwestern Illinois, including St. Clair, Monroe, Marion, Macoupin, Bond, Randolph, Madison and Clinton counties.
Accumulating snow is likely over portions of east central and southeastern Missouri as well as southwestern Illinois on Thursday, the hazardous weather warning said.
