Friday I downloaded & installed Weather Bug ($1.99 version not the free one) and it can put a widget Doppler Radar Map on the home screen! It came in handy last week when I was at ORD. Note: the map takes 4x4 space. But I'm tempted to have one home screen with maps for the various airports I need to go through this week. This is a static map and only auto updates every 3 hours but you can force it to refresh.
