Our own Mass. Emergency Management Agency warns we might need to get out the clubs to defend our homes from golf-ball-sized hail tomorrow afternoon - well, rush to a secure place away from windows. Granted, eastern Mass. has only a "low" risk of jumbo hail (as opposed to the "enhanced" risk west of 495), but the assessment also includes "a risk of isolated tornadoes," so keep your eyes on the skies tomorrow.
If you want to feel jitterier, there's always the ALL-CAPS rendition by the National Weather Service:
THE POTENTIAL EXISTS FOR A SIGNIFICANT SEVERE WEATHER OUTBREAK TUESDAY AFTERNOON AND EARLY EVENING...BUT WILL DEPEND ON HOW MUCH SUNSHINE DEVELOPS AHEAD OF A COLD FRONT. IF ENOUGH SUNSHINE OCCURS... SEVERE THUNDERSTORMS WILL BE CAPABLE OF PRODUCING DAMAGING STRAIGHT LINE WIND GUSTS AND LARGE HAIL. ISOLATED WIND GUSTS OF 70+ MPH OR EVEN HAIL UP TO THE SIZE OF GOLFBALLS WOULD BE A POSSIBILITY. IN ADDITION...AN ISOLATED TORNADO OR TWO MAY OCCUR.
