‘Excessive’ heat wave to hit Chicago in time for Pride Fest weekend

‘Excessive’ heat wave to hit Chicago in time for Pride Fest weekend

Take every precaution needed to stay safe in the heat with indices near 100 degrees. One difference is that we will be tracking an isolated storm or two showing up across the Bluegrass producing some quick hitting showers. Today marks the another transition to hotter weather, as this weekend will be our third heat wave of the year! The criteria for an alert is a heat index of 95, and forecasts say the index, calculated using temperature and dew point, could be higher than 95 Sunday and especially on Monday.

The last weekend of spring will feel a lot more like summer as hot air surges into the Sault region this weekend.

Father's Day will be a touch cooler but not by much. An Excessive Heat Warning is in effect through Monday where heat index readings will range from 105° to 107° for four straight days. Before the storms arrive, temperatures will reach the upper 80s at the beach and lower 90s inland. Along with that heat streaming in from the Midwest will be very humid air, which could push dew points into the high 60s or low 70s. Highs in the low 80s, 70s lakefront.

Monday afternoon will see a slight chance of showers or thunderstorms in the afternoon and evening before temperatures drop again, according to the weather service.

A cold front approaching from the northwest is expected to pass through the area late Tuesday and Tuesday night, possibly bringing with it showers and thunderstorms. The only day where it looks like records could be broken is Sunday as shown in the above graphic.
