Winter Storm To Continue Across The State On Saturday (Fri-Sat, Jan 10-11th) Update #9

(12:30AM - 1/11/30) The winter storm will continue to affect the state on Saturday.

Rain will continue to transition to a mix of snow/sleet/freezing rain across more of Northern and Western Illinois Saturday morning, this in addition to areas that changed over Friday night. Minor snow, sleet and ice accumulation is possible across Northern and Western Illinois Saturday morning through early to mid afternoon.

The main focus will be early to mid Saturday afternoon on into Saturday night. As the main storm system pushes northeast across the region and strengthens, a large area of snow is expected to develop across adjacent states to the southwest on Saturday. This snow will then spread across much of Northern and Central Illinois, Saturday afternoon into Saturday night. Periods of heavy snow with 1-2”/hr snowfall rates and thundersnow may be possible. Snowfall accumulation of 1-3” will be widespread across the aforementioned areas, with upwards of 3-6” possible with northward extent across Northern Illinois.

Below is the TAM snowfall forecast for this event.
