Thanks to Anson Mount for this shot of Thursday afternoon's snow at Algonquin. Snowfall there has reached 1.5", Anson tells us. Thunder and lightning has accompanied the snow during the late afternoon and evening at Downers Grove and Oak Brook. Lightning data indicates the most prolific cloud to ground—236 strokes in the 10 minute period ending around 6:50 p.m. Thursday evening has occurred in the far southern suburbs. There are indications bursts of heavier snowfall is accompanying the east/northeast-bound thunderstorms there. Visibilities this afternoon and evening have dropped under one-quarter mile at times in the heaviest spells of snowfall. Full weather details on Thursday evening's Nine O'Clock News.
