After a short reprieve, Chicago comes under another heat wave Monday and Tuesday.
Temperatures begin the week in the upper 90s with heat index readings between 95 and 100. The same sweltering conditions continue into Tuesday with temps topping out between 95 and 100, according to NBC Chicago meteorologist Andy Avalos. Heat indices could reach 100-105.
Three consecutive days of triple-digit temperatures set records each day of that heat wave, raising the water temperature in Lake Michigan to 80 degrees.
This round of heat isn't expected to be quite so hot, but the National Weather Service released a hazardous weather outlook warning of triple-digit heat indices.
A cool front moves in Tuesday night with a few potential thunderstorms in the late evening or overnight hours. A few more scattered showers and thunderstorms are likely Wednesday morning as conditions turn less humid and temps dip to the upper 80s inland and 80 near the lake.
Rain stays on the radar through Thursday, but sunshine returns Friday with temps settling into the upper 80s to lower 90s.
