High pressure across the region will bring us lots of sunshine on Tuesday with high temperatures peaking in the mid 90's.  The heat index on Tuesday will range from 103 degrees by the coast to 113 degrees for some inland areas.  Isolated storms will be possible from 9AM until 2 PM for coastal and bay areas; with storms staying along and east of I-75 between 2PM and 9PM. 

On Thursday, as the ridge of high pressure weakens, moisture will spread northward as a tropical wave moves from the Caribbean toward the Gulf of Mexico. The added moisture along with light winds and more active sea breezes will increase our storm coverage to 60%.  With the additional clouds and rain, we will shave several degrees of our daytime highs bringing us back to normal levels with highs around 90 degrees.

Tuesday:  Sunny skies for the morning, with a low temperature around 77 degrees. Partly cloudy skies are forecasted in the afternoon and very hot with a high temperature near 94, and Heat Index values between 103 - 113 degrees. Some isolated T-Storms developing between 12pm-9pm.

Wednesday Scattered showers and thunderstorms, mainly after 2pm. Mostly sunny, with a high near 93. Heat index values as high as 102. Calm wind becoming west southwest 5 to 9 mph in the morning. Chance of precipitation is 40%.

Thursday A 60 percent chance of showers and thunderstorms, mainly after noon. Partly sunny, with a high near 90. Calm wind becoming south 5 to 8 mph in the morning.

Friday Showers and thunderstorms likely. Partly sunny, with a high near 89. Light south wind becoming south southwest 6 to 11 mph in the morning. Chance of precipitation is 60%.
