Golf ball sized hail and wind gusts of up to 64 mph recorded!

June 12, 2011 - The atmosphere was highly unstable with hot temperatures at the surface and cold air aloft.  High temperatures reached the mid-90s just inland from the coast with areas from West Kendall to Pembroke Pines reaching 95F and Heat Index readings near 100F due to high humidity. This lead to high instability and the development of thunderstorms.

Thunderstorms first developed across southern Miami-Dade County. These thunderstorms produced a northward moving outflow boundary, colliding with the inland moving Atlantic sea breeze to result in a thunderstorm developing further to the north near the intersection of Krome Avenue and Okeechobee Road. This thunderstorm quickly became severe. For a look at the progression of the severe thunderstorm development, click the below images.



This severe thunderstorm produced 3 independent reports of golf ball sized hail (very rare for South Florida) and wind gusts as high as 64 mph in Weston.  For a complete listing of the severe reports click here.

Here are some pictures of the hail which occurred in Weston.
