The heat index will approach 100 degrees again today as hot, humid air settles over the Tampa Bay area.
A steamy morning will lead to a hot afternoon, as temperatures will cross 90 under mostly sunny skies, News Channel 8 meteorologist Leigh Spann said.
There is a 20 percent chance of isolated afternoon thunderstorms, primarily near the coast and along and east of I-75.
The muggy conditions will remain tonight after the rain tapers off, with lows in the upper-70s.
