Ever wondered how accurate your weather forecast actually is? VeriSky lets you find out.

See the Full Picture: VeriSky overlays past predictions against what actually happened, so you can see exactly where the forecast got it right and where it missed. Scroll back up to 7 days to compare what was predicted versus observed conditions.
