Verification Methods in the NWS National Blend of Global Models

The course is good at describing the types of verification techniques that can be used. But there seems to be a barely substantiated bias towards URMA as the best analysis package. It only talks about temperatures and makes mention of wind and QPF but then never shows how URMA is the best analysis for these parameters. It also has a bias toward Blend as the superior forecast, which may be right. But it does not do a very good job of showing where Blend may have some weaknesses.

It was hard to see the numbers!

The graphics displayed weren't clear enough. The numbers within the pictures were not legible enough as well.

A little difficult to follow.

This lesson was simply propaganda promoting URMA/RTMA. I do agree that a National approach to NDFD needs to come, but this lesson was more about convincing forecasters that URMA/RTMA blending is better than current collaboration methods making NDFD. I'm fine with a National approach, but it isn't necessarily superior to collaboration approach for anomalous weather (e.g., mountainous terrain of western CONUS more challenging for URMA/RTMA blend, with NBM far inferior to SuperBlend method in quiescent weather).

Great overview of the verification of the National Blend.
