CFSv2 weeklies indicate building warmth across the Northern Tier weeks 1-2 before a cool pool forms and expands weeks 3-4.
As for the GFS ensemble, it indicates cool covering much of the rockies and plains and warm east. A subtle flip to warm days 6-10 before cool returns to the east in the day 11-15.
