When changing between the main page and grid page on my Tempest, I have noticed a significant difference in the forecasts - most significantly with precipitation %. Today, for instance the main page shows a 30% chance of rain - and the grid page shows an 84% chance. [https://tempestwx.com/station/19971/](https://tempestwx.com/station/19971/) [https://tempestwx.com/station/19971/grid](https://tempestwx.com/station/19971/grid) Is this by design, or is this a bug of some sort?? Thanks, Mark DesotoCountyWeather(.com) ---
