Although the midday hours should be primarily dry for cookouts and outdoor activities on the Fourth, there could be a stray shower or thunderstorms here or there, but primarily, it’ll just be very warm and humid. 

As afternoon Independence Day parades and activities commence, showers and storms will gradually increase in coverage, so have rain gear and also alternate plans ready.

Rain and storms will be widespread Thursday late-day and evening. If you’re planning a barbecue or gathering the family to head out to fireworks, this appears to be the wettest part of the day.

By fireworks time around 9 p.m., thunderstorm coverage should be on the wane, but there will likely still be some showers that could threaten some shows, so stay with WUSA9 and also download the WUSA9 App to stay on top of changing and evolving weather.

Fireworks Forecast

Most fireworks shows should get off OK, including the National Fireworks show on the National Mall, but there will still be some showers around, though, and perhaps a thunderstorm with temperatures still in the sticky 80s.

Another Heat Wave

In addition to the storm threat, it will also be hot and humid for the holiday. Actual temperatures will climb back into the low-mid 90s, but feel more like around 100 degrees once you factor in the humidity. The 90-degree-heat will likely stick also around all the way through the weekend and into at least early next week, meaning yet another steamy heat wave setting up.
