Snow Falling Across Much of Midwest, Parts of Northeast...

The above radar mosaic shows a large area of light to moderate snow across much of the Midwest and western portions of the Ohio Valley. Snow is also falling across the region from upstate New York on into Maine.

Snow is beginning to accumulate, lightly, in the Chicago area, as you can see on this recent picture posted on twitter:

The latest run of the experimental HRRR computer forecast model is calling for widespread snowfall of 3-6 inches, with localized amounts near 8 inches across the greater Chicago area through Midnight this evening:

Travel is highly discouraged, as Northwest winds of 20-30 mph with gusts to 40 mph will cause blowing and drifting snow in many areas, resulting in a further reduction in an already low visibility situation.

The threat of locally heavy snow will spread Eastward overnight, with widespread 4-8 inch amounts forecast across much of Michigan by 7am EST on Friday:

...and on into upstate New York during the day Friday (the following image is valid 7pm EST Friday:

Extensive travel delays can be expected at the major airports across the Midwest and Northeast through Friday.  This will especially be the case at the Chicago area airports this afternoon and evening.
