Attached is a one page briefing along with the relevant graphics regarding the potential for severe thunderstorms and heavy rainfall/localized urban flash flooding this afternoon. While damaging wind gusts are the primary threat, the greatest risk for an isolated tornado or two is across western MA/CT but potentially as far east as Metrowest. 

Looking ahead, it is likely that oppressive heat and humidity will return later this week. An initial heat index forecast is attached. Thank you!
