MIAMI — The heat makes a comeback this weekend! Record heat will be possible for Miami today, with a forecast high temperature of 93 degrees, and the record stands at 93 degrees last set in 1958. Humidity will also remain high as the moisture “tail” from Helene remains draped across the area. This has led to a Heat Advisory being issued for Miami-Dade and Broward counties, with a heat index range of 105 to 110 degrees expected.
