...Scattered To Numerous Storms This Afternoon with Heat Indices 100 To 103 Inland Areas This Afternoon...

Today: Partly cloudy with chance of showers and thunderstorms in the morning...then mostly cloudy with showers and thunderstorms likely in the afternoon. Highs in the lower 90s. South winds 5 to 10 mph. Chance of rain 60 %.

Tonight: Partly cloudy. A 40 % chance of showers and thunderstorms in the evening. Lows in the lower 70s. South winds 5 mph.

High temperatures in the mid 90s inland will push heat indices to 100 to 103 degrees this afternoon. Exercise extreme caution when outdoors.

Scattered to numerous storms are expected to develop today mainly during the afternoon and evening as the sea breezes begin to develop and progress inland. The most coverage of storms is expected to be west of I-95. Some storms will be strong and produce frequent cloud to ground lightning, strong and gusty winds and locally heavy rainfall of over 2 inches. This heavy rainfall may cause local flooding of low lying or poor drainage areas.

Today's pollen level: 2.1-Low (on a scale of 1to12): predominate pollen: Grass and Oak.

Forecast Details: weak pressure pattern will continue with area sandwiched between upper ridges to the west and east. This opens the door for spokes of energy to ride south across the area which will enhance thunderstorm activity that will develop along the sea breezes and move inland. Have continued highest rain chance (60%) for inland northeast Florida generally between I-95 and I-75. The stronger storms will be capable of frequent cloud to ground lightning, strong gusty winds and locally heavy rain of 2+ inches due to the light steering (1000-700 mb) winds. Continued hot and humid with highs inland in the mid 90s with heat indices 100-105. Upper 80s to near 90 at the coast with heat indices just under 100.

Did you know that...?

1972 - Hurricane Agnes moved onshore near Cape San Blas FL with wind gusts to 80 mph, and exited Maine on the 26th. There were 117 deaths, 26 of them in Florida, mainly due to flooding from North Carolina to New York State, and total damage was estimated at more than three billion dollars. The rains of Hurricane Agnes resulted in one of the greatest natural disasters in U.S. history. Agnes caused more damage than all other tropical cyclones in the previous six years combined (which included Celia and Camille).

1987 - It was a warm June day, with plenty of thunderstorms east of the Rockies. A man was struck by lightning near his home in Manatee County FL.
