Today is the longest day of the year!

Hot weather expected today, with near record highs near 100. Peak PM heat indices to 105 degrees, especially over NW IL.

According to National Weather Service, hot temperatures near 100 will last through sunset before strong storms could hit Chicago between 7 and 10 pm this evening. The storms are more likely to move over Northwestern Illinois with the chance that they swing over Chicago. If they do they could penny-sized hailstones with wind gusts up to 60 mph.
Cooler and drier weather is expected from tomorrow through Friday before it warms back up over the weekend.
The weather won’t prompt a heat advisory like last week but NWS is still encouraging people to “plan ahead to avoid heat-related illness and check on relatives and neighbors.”
