Snow is approaching from the southwest. The part coming into the viewing area now is virga or snow that is evaporating in the dry air on the way down. You have to go south of Champaign to find snow reaching the ground. Some sleet may also be occurring with it.
Snow is falling in central Illinois & on the move northeastward.
Central Illinois bservation sites reporting snow falling are in bold. Springfield has moderate snow now with a visibility of 0.50 mile with interstates snow-covered as seen on IDOT cam. Rates have been high enough in Illinois with temperatures cooling to 30-32 for rapid road accumulation.

Looks like some snow & bit of sleet then changing to some rain with more snow in the northwest areas & much less in the south & southeast areas.
It should taper to some drizzle with fog tonight as brisk east winds become northeast & light to calm.
So, any snow will not last too long.
After wet-bulbing to 31-36 over the area, temperatures tonight will run 35-38.
1-2" is possible over northwestern & northern areas with much less as your go southward. So, 1-2" from near Ambia to Monticello to Lake Cicott to Denver & northwestward.
At this point, it appears the southeast may see 0.5" or less & 0.5-1" Greater Lafayette, but we will continue to monitor for sudden tweaks.
Best accumulation would be on grassy areas, decks, car wind shields, roofs & trees & white surfaces.
The NSSL model & NAM 3km seem to be the only ones capturing what is occurring in central Illinois the best right now, so those are the preferred models to go by currently.
Monday looks gray with some drizzle tapering & fog decreasing & highs in the 40s.
Tuesday looks gray & gross with gusty east to northeast wind increasing to 20-30 mph with cold rain developing & highs in the 40s.
Some waves of rainfall (& a few t'storms) are possible mid to late week as warm front moves northward.
Warm, windy weather with some severe weather risk is possible at the very end of the week.
