(10:00PM - 11/25/18) A short term/quick update on the blizzard that is currently affecting portions of the state...
The rain/snow line currently sits from downtown Chicago, down towards Central Illinois. This is steadily pushing east, with a transition to snow occurring. Heavy snows are likely overnight across a good portion of Northern and Central Illinois. Winds gusts of 30-50mph will also continue to be likely, leading to blizzard conditions. Additionally, the heavy/wet nature of the snow combined with the high winds will likely lead to widespread tree damage and power outages.
Our earlier snowfall TAM is still on track, with a large swath of snowfall totals of 9-12" being still likely, with localized totals of 12-15" possible as well.
