Chicago might get measurable snowfall tonight, which would be the fourth-latest first fall in history and the first since April 18th:
Though flurries have been observed within the city limits four times this month and seven times since the snow season began this year on Nov. 9, the only "measurable snow" which has fallen has been across the northern suburbs.
That may change as a light-snow-generating disturbance swings across the metro area Thursday night. The system's approach will become more and more evident Thursday as sunshine is filtered by an influx of clouds out ahead of the disturbance's light snow, particularly Thursday afternoon and evening.
If there's a snowstorm in Chicago's future the next two weeks, there is NO computer model consensus on it at this point. That can change fairly quickly this time of year. But for now, Thursday night's wave of light snowfall is the only definitive snow threat the metro area faces in the short term.
