12Z NAM/GFS evaluation along with final preferences
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Overall model preference: General model blend
Confidence: Slightly above average

19Z update: No significant changes were noted in the 12Z
ECMWF/UKMET/CMC relative to their previous cycles.

The guidance continues to show good agreement regarding mass
fields from the surface to the upper levels with relatively minor
differences in the details. Given good run to run continuity
through Friday morning from the West Coast to the East Coast, a
general model blend is preferred.

For preferences within areas which are expected to received heavy
rainfall, consult WPC excessive rainfall discussions.
