The main event on the borough calendar tonight is the annual Conshohocken fireworks display, launched from Sutcliffe Park at roughly 9:15 p.m. If you have watched from a stoop, a rooftop, or the middle of Fayette Street in years past, you know the show is big enough to be seen from most of town. Sutcliffe Park itself and the streets around it will be closed to the public during the launch, so plan your viewing spot accordingly.
The one wrinkle worth taking seriously is the weather. AccuWeather and WHYY are both flagging dangerous heat continuing through the day, with Philadelphia's heat emergency stretching into the holiday weekend and severe storm chances rising as we get closer to the Fourth. Translation for families: hydrate, bring more water than you think you need, and check the sky before you commit to a folding chair.
