One night, the whole country's sky — photographed. The forecast made a claim about every show. Tonight, the sky answers.
The Fireworks Index scored the sky over 1,719 shows before the first shell went up — cloud ceiling against burst height, the smoke-clearing wind, visibility, darkness.
A forecast is a claim; a photograph is the proof. Every frame you add is an observation — the ground truth the Index is measured against, one sky at a time.
As the shows fire across the time zones, the record fills — one frame of the country's fireworks, all at once. Curated as they come in.
The forecasters we're watching on the 4th. If they call the night's sky, we'll feature the call here — beside what the sky actually did. Presence here is an open invitation, not an endorsement.
Not on the list? Tweet your show's sky at @tomorrow_io with #FireworksIndex — we're reading, and the best calls get featured.
