Friday Could Be Hottest Day of the Year

Meterologists predict heat advisories this weekend

Chicagoans might want to bring an extra water bottle during weekend Fourth of July celebrations.

Friday could be the hottest day of the year so far, according to NBCChicago's Andy Avalos, with temperatures reaching the mid- to upper 90s and heat index temps estimated around 105.

Saturday is expected to give some relief from the heat, though temperatures will remain in the lower 90s with heat indexes in the upper 90s. Sunday likely will cool off slightly, with temperatures in the upper 80s.

If Friday's temperatures reach the estimate, it would be almost 20 degrees hotter than the average high for this time of year, which is usually in the lower 80s.
