Highs near 80 inland, upper 70s lakeside. Lake water temps remain dangerously cold in the mid 40s. 

Extended outlook calls for unseasonable warmth with highs in the upper 80s and to near 90 degrees this coming week, which are close to record high temps. It’ll be our longest stretch of warm weather since last October.  We’ll start getting much muggier starting Tuesday, which is also when there’s a slight chance of thunderstorms late day Tuesday and Wednesday, but only about 20% coverage for Chicagoland. Temps look to cool back into the 70s– which is still above normal– by next weekend.
