Heavy snow and frigid temperatures are expected in the Chicago area through at least Tuesday morning, with several Chicago-area counties under a winter storm warning.
Some locations could see a foot of snow or more, but models vary widely because of the impact of lake-enhancement of the snow storm. If the snow is heavily influenced by the lake, then models, such as the HHR model showing up to 16 inches of snow in parts of Chicago, could come into play.
Even if the lake doesn’t fuel huge additional snowfall totals, 4-to-8 inches of snow could fall by Tuesday morning, and when coupled with frigid conditions could make for a travel nightmare on Monday night and into Tuesday morning.
Here are the latest weather headlines from across the Chicago area:
