Preference: General model blend, with less weight given to the NAM
across the northern Rockies/High Plains Mon morning
Confidence: Average

For most of the larger scale systems, a general model compromise
may be applied.  This includes the 00z ECMWF, which in comparison
to its 12z run is now notably slower with the upper trough across
the northern Rockies/High Plains Mon morning.  While the ECMWF has
moved into better agreement with the model consensus, the NAM is a
bit of an outlier with this system -- closing off a deeper upper
level center near the Montana-Canada border that is not
well-supported by the other models.
