Florida Heat Advisory: Relief on the Way?

A heat advisory is in effect for Broward and Miami-Dade counties today until 7 p.m., with heat indices potentially reaching 105 to 110 degrees. While Wednesday morning remained largely dry, scattered showers and thunderstorms are expected to develop later in the day due to increased moisture and lighter breezes.

Looking ahead to Thursday, spotty showers and storms are forecast, with high temperatures in the low to mid-90s feeling like the 100s due to humidity. By the weekend and into early next week, Saharan dust and drier air are expected to reduce rain chances, though the summer heat will continue with highs in the low 90s.

The CBS News Miami NEXT Weather team is tracking three areas in the tropics. A tropical wave in the central Atlantic, located approximately 800 miles southwest of the Cabo Verde islands, has a high potential of becoming a tropical depression within a couple of days. However, this system is expected to encounter strong wind shear and drier Saharan dust this weekend and early next week.

Another wave in the central subtropical Atlantic has a medium potential for development over the next seven days, but it is forecast to move away from the U.S. and reach cooler waters by Thursday, ending its development chances. In the eastern Atlantic, a tropical wave off the coast of West Africa is producing disorganized showers and thunderstorms. While environmental conditions are generally conducive for some development over the next several days, this system has a low potential for development over the next seven days.
