No surprise we saw some decent tornadic supercells today... The Key West and Miami 0z soundings are both very favorable for tornadic supercells, with the Key West sounding showing ~2000 j/kg CAPE and >500 0-3km SRH.
EDIT: Just saw that the 1z Day 1 from SPC shows MDT risk with 15% hatched tornado risk for sw FL. This is quite impressive, and I don't think I have ever seen such a high risk for a landfalling hurricane. I've seen 15% before, but not 15% hatched. Typically, the highest tornado threat develops the day or two after landfall, as the cyclone weakens and allows for the development of stronger instability downstream.
