NAM model errors
I have noticed two errors with the NAM model. The first is super simple to fix and that's changing the label from "NAM 3km" to "NAM 5km". The second error is that the line marking where the NAM forecast ends and where the GFS forecast begins is not correct. I consistently appears between 6 AM and 9 AM when it should really be appearing between 12 PM and 3 PM since it is a 48 hour forecast model, not a 42 hour model. In fact, the data shown for these hours is actually from the NAM forecast up until 3 PM, then you can see the GFS model data is shown from 3 PM and beyond. The error is simply where the line is being drawn to mark where one forecast ends and the other begins.
