Some 15% EF0 tornado probs developing in that band.
Broken low-topped line or lines of gusty showers & t'showers should race through soon. Risk of a single isolated strong to severe gust for a cell that can really pulse up. Parameters are such to mention small risk of brief rope spin-up of EF0 tornado from one of the showers or t'showers where CAPE can reach 400 J/kg.
Clearing should then develop & it will be windy & cooler.
