NAM Continental US is a high resolution nest, that runs within the larger NAM suite of models. NAM is a mesoscale model, which means that the numerical analysis is able to model land, and other features, at a higher resolution than in a global model, leading to improved forecast accuracy.

This model would be an excellent choice for a short range weather forecast for anybody living in an area covered by its domain.

Here is a quote from the NAM homepage:

The North American Mesoscale Forecast System (NAM) is one of the primary vehicles by which NCEP’s Environmental Modeling Center provides mesoscale guidance to public and private sector meteorologists.
