...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE FLORIDA PENINSULA...
...SUMMARY...
A couple of strong to locally severe storms could still occur
through early/mid-afternoon across the eastern Florida Peninsula.
...Florida Peninsula...
The overall environment/scenario is trending less favorable for
severe storms, but a couple of strong/locally severe storms could
still occur across the eastern Peninsula through
early/mid-afternoon. Overall updraft intensity/lightning flashes
have diminished over the past few hours, with an exception being
some stronger storms at midday near the immediate coast of southeast
Florida, which are focused along prior outflow. This activity should
continue to quickly shift offshore away from the upper Keys and the
remainder of South Florida. Additional development across the
central/south-central Peninsula also seems unlikely or at least
uncertain given the prevalence of cloud cover and a tendency for
weakening convergence through the afternoon.
