The ongoing heat wave poses risks of heat-related illnesses, particularly for vulnerable populations such as the elderly, children, and those with pre-existing health conditions. Outdoor workers and individuals engaging in prolonged outdoor activities are also at risk. The storms expected Wednesday afternoon could bring damaging straight-line winds and isolated hail, though tornadoes are not anticipated. Cooler temperatures and rain over the weekend may disrupt outdoor Memorial Day plans but will provide relief from the heat.
