Metro-east skies cleared Tuesday afternoon and by evening, roads were dry and most accumulation was gone when the temperatures rose above freezing.
By nightfall, the temperature fell again and the wind kicked up, but no additional accumulation stuck around, despite a few flurries.
The National Weather Service in St. Louis originally forecasted an inch of accumulation in the metro-east for rush hour, but later changed the forecast to less than a half inch accumulation of snow in the region.
About a dozen flights were canceled Tuesday morning at Lambert-St. Louis International Airport. Some of those flights were related to nearly 1,000 flights canceled out of Chicago's Midway and O'Hare airports in advance of a winter storm expected to blanket the Windy City with up to 10 inches of snow.
Skies will be mostly sunny Wednesday, with a high of 38 and gusty winds.
The temperature will climb above normal later in the week, with a high of 43 expected Thursday and 54 predicted for Friday and possibly 60 by Sunday.
