Don't let em spook you... T-storms can happen any time in S. Fla...
Yes, they are more frequent after noon, but that doesn't mean that at
precisely noon the state goes into aviation lock down... I have flown
all over that state at all times of the day numerous times over the
past 25 years - for example, plowing right down the West coast three
miles off shore to get to Fun-N-Sun by 8PM...
Most trips I never saw a bumper, other times I did have to deviate 20
miles or so, once I had to land and wait 2 hours for a line of T-storms
to pass over at 10AM, and then went back to motoring North..
Fly smart, deviate around the bumpers, and don't worry about what time
you get there after noon...
