SLIGHT to ENHANCED RISK for severe is up for nothern Illinois. The SLIGHT RISK is painted Warren to western Pulaski counties & northwestward with MARGINAL elsewhere in the viewing area.

Here, a few severe storms are possible 4 p.m.-12 a.m. generally with wind, isolated tornado, hail risk. Coverage will run at 50% in the viewing area.
Before that a random small cluster or two of storms are possible.
After a couple isolated storms possible on tail-end of MCV's outflow boundary Sunday, rather compact MCV may bring some storms Monday with risk of a couple of severe storms in the afternoon-evening.
