Outside of some areas of fog and drizzle, mostly quiet and cloudy conditions are the norm across the state right now as the upper level low and associated low pressure system at the surface continues to slowly meander its way through the state. More accumulating snow is expected later tonight and overnight. The latest follows below....
Taking a look at current radar across the region this afternoon, we can see that the brunt of the activity is off to our east across portions of Michigan, Indiana, and Ohio and this is the area to watch as this precipitation should continue to be pulled back/curl northwest into the northern portions of the state later tonight and overnight.
Below is an animation of the evolution of the snow across the northern portions of the state tonight. Precipitation will curl back northwest into northern Illinois and then changeover to snow across a fairly wide area of northern Illinois as you can see below. Snow will then continue in a light to moderate intensity with embedded isolated areas of heavy snow into tomorrow morning. Snow showers then could continue into tomorrow afternoon but accumulations will most likely slow or stop completely by morning as surface temperatures warm.
We have not changed our thinking is expected snowfall totals and these amounts are the multi day totals from when the event began on Wednesday.
