Forecast Differences

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.

Is this by design, or is this a bug of some sort??

Thanks,
