Why Some Fireworks Displays Are Spectacular and Others Disappoint: The Weather Behind the Show
The Forecast Matters More Than You Think You’ve been to fireworks displays where the shells burst in brilliant, perfectly defined starbursts against a deep black sky, each explosion distinct and vivid before fading cleanly.
