Loading live data…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.

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.
