Quad Cities, Iowa/Illinois – The Quad Cities are in for a scorching weekend as humidity builds and temperatures rise through Tuesday. Starting today, hot, sticky conditions will persist, with Monday expected to bring peak heat indices above 100°F. Storms over the weekend, particularly on Saturday, may offer brief relief, but the real heat will ramp up as the weekend closes, pushing the area into a prolonged stretch of high temperatures.
According to the National Weather Service, heat indices will be in the 100–105°F range from Sunday through Tuesday, making outdoor activities risky for anyone without proper precautions. Additionally, storms are expected to produce heavy rainfall and isolated severe conditions, with damaging winds and flash flooding risks intensifying. A Flash Flood Watch has been issued for areas south of Highway 30, particularly this evening.
Travelers and residents are advised to limit exposure to the sun, hydrate, and avoid areas prone to flooding, particularly as repeated storms may inundate low-lying areas. Street flooding is a concern, and roads like Highway 30 could see rising water levels quickly. The heat combined with these storms is unusual, bringing a mix of dangers for commuters and outdoor activities.
As the week progresses, less humid conditions are expected by Wednesday, giving residents a break from the extreme heat. However, the storms and flooding risk could continue into the weekend, requiring ongoing monitoring.
