An excessive heat dome is impacting Fourth of July festivities across the United States, particularly in Washington, D.C., where the nation is celebrating its 250th birthday. The extreme heat forced the cancellation of the city’s annual parade late Friday and delayed the opening of the Great American State Fair and other events until later on Saturday.

Despite the heat, President Trump is expected to deliver a "long" Salute to America Celebration speech late Saturday on the National Mall. The speech will be followed by what is anticipated to be a record-breaking fireworks display.

These adjustments reflect efforts to balance public safety with the patriotic celebrations marking this significant milestone.
