New Orleans weekend weather

This weekend in New Orleans, LA, model by model. Weekend forecasts are far enough out that the models often split — so we show you where.

Weekend

The models centre on about 93° across the weekend. Agreement is low — the weekend is genuinely up in the air at this range. Rain chance reaches 84% on at least one model.

The models are 10° apart on this day. That is genuine uncertainty — any app showing you a single confident number is hiding it.

The models often agree on temperature and still split on rain — and rain is usually what decides whether a plan survives. A wide rain range means the shower is genuinely uncertain, not that the forecast is wrong.

Common questions

Will it rain this weekend?
At least one model puts the weekend rain chance as high as 84%. Weekend forecasts sit far enough ahead that models frequently disagree on showers — when they do, no single app can honestly tell you it will or will not rain.
How reliable is a weekend forecast?
It depends how far away the weekend is. Forecast error grows steadily with lead time, so a Saturday forecast made on Friday is far stronger than one made the previous Monday. The honest signal is model agreement: when they converge the forecast is solid, and when they spread the weekend is genuinely uncertain.
