DGEX: Downscaled GFS with Eta Extensions Model

[mikegeukes]

Downscaled GFS with Eta Extension Model:
-Just wondering if anybody use the DGEX model at all in forecasting
-What are your opinions on the DGEX, its strenghts, weakeness, etc in daily forecasting.

Since it's a medium-long range model only, and medium-long range severe weather forecasting is not of much use, I can't see how it helps storm chasing that much...

It's primary purpose is to make the digital gridded NDFD forecast easier to generate for NWS mets.
