Tomer’s Take: The Western pattern turns tranquil with one exception. An area of low pressure develops 12/13-12/14 in Southern CO and Northern NM with moderate to heavy snow accumulation. Otherwise, the storm track stays quiet through 12/20.
In the Northeast, a Nor’ Easter might occur on/about 12/18 but it looks warm.
