The record-breaking heat provided a brief taste of summer for Chicago residents, but the rapid temperature drop later in the week could pose challenges. Those sensitive to sudden weather changes, such as the elderly or individuals with certain health conditions, should take precautions. The potential for frost later in the week may also impact outdoor plants and gardens, particularly in outlying areas where temperatures could dip into the upper-30s. Additionally, showers and thunderstorms expected Tuesday night could lead to localized disruptions.
