The city of Chicago is bracing for a tempestuous week ahead, with several rounds of thunderstorms anticipated through the end of the working week. According to the National Weather Service’s Chicago forecast, today carries a 20 percent chance of showers and thunderstorms after 4 pm, with mostly sunny skies and a high near 84 degrees. The wind, starting west-northwest at 5 to 10 mph, will become easterly in the afternoon, capable of gusts up to 15 mph.
As night falls, so does the likelihood of showers and thunderstorms, with a 50 percent chance mainly after 1 am. The city, partly covered by clouds, will see temperatures lowering down to around 72, the southeast wind changing to a southwesterly flow after midnight. Transitioning into Wednesday, Chicagoans will face elevated temperatures with highs near 90 and heat index values reaching as high as 95, accompanied by a south wind flowing at 5 to 10 mph. "Limited Thunderstorm Risk" with an associated "Level 1 of 5 Severe Thunderstorm Risk" is also detailed for Wednesday in the Hazardous Weather Outlook by the National Weather Service.
Moreover, the same outlook involves a "Level 1 of 5 Tornado Risk" and "Level 2 of 5 Damaging Wind Risk... up to 70 mph," among other severe weather conditions for today. Thunderstorms later this night could further bring damaging winds, large hail, and concerns of very heavy rain that might lead to flash flooding. The vigilance will carry over into Wednesday and Thursday, with a "Limited Flooding Risk" and persisting thunderstorm threats.
Towards the weekend, the chances for precipitation slightly abate, but not without leaving behind a 50 percent likelihood of showers and thunderstorms on Friday. Heading into the weekend, the city is forecasted to bask under sunny and mostly clear skies with highs resting comfortably near the mid-80s. The lake will not be spared; a "Limited Thunderstorm Risk... with an associated: Level 1 of 5 Thunderstorm Wind Gust Risk... up to 35 knots" is projected for the Illinois and Indiana nearshore waters of Lake Michigan, as indicated by the Hazardous Weather Outlook.
Apart from the intermittent storms, local meteorologists emphasize the backdrop of warmth and humidity afflicting the Windy City. Stepping outside might feel like stepping into a sauna, with a "Level 1 of 5 Excessive Heat Risk" in play for south of Interstate 80 the coming Wednesday and Thursday, as reported by NWS Chicago's post. Summertime in Chicago, as often is the case, proves itself not just a season but a force, one that oscillates between the balmy sunshine and the sudden rage of tempests.
