Quad Cities, IA/IL – Temperatures across eastern Iowa and western Illinois are surging into summer-like levels this week, with highs forecast to break into the 90s by midweek and potentially set new records by Thursday.
According to the National Weather Service Quad Cities office, daily highs will rise steadily, peaking Thursday between 84°F and 94°F with strong southwest winds contributing to the heat index. Forecasters expect Wednesday to reach 82°F to 89°F before Thursday’s spike, which could mark the hottest day of the season so far.
This uptick in heat is accompanied by isolated showers and thunderstorms, particularly in the afternoon and evening hours. While confidence remains low due to a warm air layer capping storm development, the potential exists for localized severe storms Thursday evening. Residents should stay alert for weather updates.
The unusual May heat presents elevated risks for heat exhaustion, especially for those working outdoors or without air conditioning. Local authorities urge people to limit strenuous activities during peak heat, stay hydrated, and check on vulnerable individuals.
This weather pattern deviates from seasonal norms, underscoring the importance of preparedness as warmer conditions set in early. For alerts and real-time updates, monitor NWS Quad Cities or local emergency channels.
