Chicago is gearing up for a sunny start to the weekend, but thunderstorms may roll in by Saturday evening. According to the National Weather Service, temperatures are expected to soar up to 93 degrees today, with the heat index nudging nearly 98 degrees, accompanied by a southward wind blowing at 10 to 15 mph, gusting up to 25 mph. Tonight's forecast points to a 30% chance of showers and thunderstorms, mainly clear skies, and a comfortable low around 76 degrees.
The warm and humid conditions are ripe for potential thunderstorms, and some areas in the metro could face a level 1 or 2 risk of severe weather, as reported by WGN-TV. Damaging winds are the primary concern, along with the possibility of heavy downpours. As the mercury hits the 90s, this stretch marks Chicago's third consecutive heat wave of the summer. Scattered clouds early on Saturday will give way to a possible shower or storm later in the day.
Amidst the heat, Lake Michigan offers a respite with its peak summer water temperatures, and the beach forecast anticipates a low swim risk despite 1-3 foot waves due to breezy conditions. Boaters heading out into the lake should be prepared for a choppier 2-4 foot swell, instigated by the 15-25 mph southerly winds.
The skies over Chicago are also expected to see some action, but from smoke rather than just clouds. Widespread wildfires have seen a large influx of smoke into the city's air. In fact, "42,670 wildfires have burned 3,613,023 million acres across the U.S. to date," as outlined by WGN-TV, with information from the National Interagency Fire Center in Boise, Idaho. As a result of the intense sunlight and heightened humidity, anyone spending time outdoors is advised to apply protective sunscreen to avoid sunburn in the shortened burn times.
Looking ahead to Sunday, the chance of showers and thunderstorms stands at 30%, with mostly sunny skies and a high near 90 expected. The ongoing pattern of warmth and possible storms extends into the early week, with a 60% chance of precipitation on Monday. It seems that Chicago residents should keep an umbrella close at hand and sunblock even closer, as the city dances between scorching sun and sudden downpours.
