.UPDATE...

The front appears to have cleared our area based on surface
observation. There are still some very small overrunning light
showers on radar over all but Levy county. The front will continue
south and east into the Bahamas and Cuba and should pull the low
clouds and showers with it.

&&

.AVIATION...

The TAFs are on track. Winds came down a little faster than
expected and CIG are still low at LAL and PGD. I will give it a
little more time especially LAL should be coming up. By the same
token FMY and RSW may need to be amended to lower CIGs. If I amend
I will bring down teh winds a little too.
