NBC Connecticut team of meteorologists has also issued a First Alert for the threat of severe thunderstorms across Connecticut today.
Instability in the atmosphere will allow for the development of the thunderstorms in the afternoon, according to meteorologist Josh Cingranelli.
Any storms that do form have the chance to be strong to severe and will contain gusty, potentially damaging winds, frequent lightning and hail.
