unfortunately all weather apps you can find require some form of data, thats how they give you the forecasts and current temperature. so unless you are able to be in WiFi, you will not find a weather app that won't require data of some kind.

The Weather Network seems the exception but the latest version is freezing my cell. Took it off and no freezing in the last 2+ days.
Was using the previous version for about 2 years.
Bummer.
