Otherwise, temperatures aloft are cold for this time of year per the KSC morning sounding which is a sign of a strong storm signal given other factors are present as well, but guidance indicates some warming will occur as the day progresses. Suspect some showers could go up along the sea breeze as there is more moisture today than yesterday, and one did manage to go up down in Indian River County west of Vero Beach proper along the sea breeze with less moisture present.
There are some other meteorological parameters that are derived from equations that would support strong activity today, but very isolated, such as some pockets of dry air.
The additive bonus that goes without saying, but that which models cannot account for at least not very accurately, is the sea breeze convergence factor coupled with any outflows from even only rainshowers that set up boundaries prior to late day time frame when heating has been maximized and various lake and sea breezes begin to interact in random fashion.
Those combined with the aforementioned enhanced low level helicities east of I-95 toward Central Florida and toward the interiors up to the storm base level could give rise to some decent true to life thunderstorm activity given the current situation, unless things change radically between now and then. The down play toward North Central is a thin veil of high level cirrus clouds that are a result of thunderstorms over the panhandle region this morning.
BEYOND: More storms are possible through Friday, but each day will be on the "Play it as it Comes" . Other days before then could see some strong storms as well; e.g. The NAM model from overnight showed more so tomorrow. The front and storm system related to the severe weather in parts of the Deep South is expected to make headway through Florida late Saturday.
Below is only a make up of an area the blogger is watching for today for potentially damaging storms most concentrated wise; official outlets have the details though.
