Coverage, source & privacy

NOAA / National Weather Service · approximately 2.5 km forecast cells. U.S. coverage. Weather is loaded only when you ask.

A location rounded to 0.05° finds up to 25 neighboring forecast cells. The 3D view prioritizes up to nine cells nearest the selected field or loaded map location. Field boundaries, crop records, and account details stay on this device. Forecasts stay in memory; they are not in backups or offline packs.

Blank areas or missing values mean unavailable data. This view does not resolve field microclimates, cloud altitude, precipitation phase, or wind changes with height. Cold and heat colors mark forecast air-temperature thresholds.
