So this is basically a global version of the HRRR? The HRRR has a 3km resolution. So does the NAM.

Yeah, basically. They're going to pull data from weather stations (like the private ones populating wunderground). Which is good but it's not like it'll be pulling soundings from those locations.

A lot of the issues upper air data is generally only collect twice a day and the grid of that data collection is very coarse. And it is almost non existent over the oceans except from airplanes. Until we have better upper air data over the Pacific forecasting individual storm systems out more than a few days over the US is very problematic. Now large scale changes are much simpler to forecast at longer ranges. Such as the flip to a colder pattern for the E 2/3 of the US that is coming in a couple weeks has been forecasted since before Christmas. Individual storms are another matter as many are just a ripple over Asia a week out from impacting the southern US.
