.Discussion...
Additional rounds of showers and thunderstorms will be possible
throughout the day, but become increasingly likely by the late
afternoon/early evening ahead of an approaching cold front. A few
storms this evening may contain strong winds. Behind the front, we
expect much cooler weather with breezy to windy conditions
developing out of the north. The front will linger near the Keys
through the week providing ample instability and moisture for
showers and storms.
