Yesterday was cloudy and cool for Father's Day (almost 20° below normal!), so grilling nearly required a jacket! Today will bring similar conditions with overcast skies, occasional showers, and temperatures remaining in the mid-60s.

The dangerous heat wave continues Sunday around Chicagoland, with heat index values near 110 in some locations.

The head index is expected to reach around 105 and an extreme heat warning is in effect until Monday, according to the National Weather Service.
