New Jersey residents can expect a picture-perfect Fourth of July weekend with clear skies, low humidity, and comfortable temperatures in the 80s. The National Weather Service forecast indicates a dry, sunny Independence Day with northwest winds around 5-10 mph.

The Fourth of July has been celebrated across the nation since 1776. But when — and how — did Americans across the country agree to commemorate the holiday with a fireworks celebration?

Round Rock's all-day celebrations will include a parade throughout downtown, pig races, a speech by Mayor Craig Morgan, and musical performances. The Elevation Band will take the stage at 7 p.m., and the Austin Symphonic Band will perform alongside the fireworks show around 9:30 p.m.
