^It must have an error with surface based warmth then.

There’s something wrong with a lot of their 1981-2010 2m climo during the winter months around the Great Lakes. Almost like they’re using Lake Superior water temps in the grids so that there’s always a large, permanent negative 2m anomaly there.

I bet it'll be possible to take a pleasant hike in short sleeves and shorts along the hudson bay on christmas.

Well in the Deep south +2-7F occurred in August and the model at a 0.0 month lead had ~0F. Denver verified +4F vs the models -3F.
