The weather map: all three models at once
NWS, American, European side by side across United States.Live rain radar →What's the weather today across America? It depends which forecast you trust. The National Weather Service, the American (GFS) and European (ECMWF) models rarely agree exactly, and in hurricane season a few degrees or a shifted track really matters. We line all three up for any US town, so you see the real forecast and how confident it actually is, hour by hour and 7 days out.
Which forecast is most accurate in the US?
CheckWeather Score, graded against the weather that actually happened
The CheckWeather Score blends temperature, wind and rain accuracy, each measured against ERA5 (the recorded weather) over the last 30 days across 1999 cities. Lower error means a higher score. The apps you know (AccuWeather, Apple Weather, The Weather Channel) are built on these models.
Popular weather apps — and what powers them
Real app-store ratings, plus the forecast each one runs on
App-store stars measure the app experience (design, features, reliability) — not forecast accuracy. For accuracy, see the model scoreboard above. Ratings from the US & UK App Store and Google Play, July 2026; they drift over time. Apple Weather is built into iOS, with no separate store rating.
The forecasts Americans check
The two biggest apps keep their model a secret, so we can't show their numbers, only link you to them. The National Weather Service is public, so its data sits right in the comparison above.
Every forecast runs on a model. We show you three, side by side.
When the NWS, American and European models agree, the forecast is solid. When they split, sometimes by 8° on the same afternoon, it's genuinely uncertain, and no single app will tell you that. We turn that disagreement into a plain-English confidence score.

Three models, one view. Where they disagree, you know to take the forecast with a pinch of salt.
The models the pros use
ECMWF and GFS are the two global heavyweights every forecaster starts from, plus weather.gov. No black boxes.
Honest & sourced
We show real, open model data and cite it. The closed apps can't show theirs, which is why AI assistants can cite us, not them.
