SPC has finally upgraded southern Florida to a slight risk of severe weather and probably will go with an enhance upgrade later on today.
I remain concern that the storms across southern Florida will not only produce damaging winds but may produce a few tornadoes.

The NAM shows the the Supercell Composite is moderate across southern Florida tonight.
The Helicity tracks from the HRRR and NAM model both show rotation tracks across the sotuhern Florida indicating storms may be rotating tonight. Rotation does always mean tornadoes, it can mean large hail too.
The radar out of Key West has been showing storms with rotation signatures all morning.
