The center of the ridging is a little west for big heat up here. With the seasonal progression, we're losing the effect of those lower heights to our northeast so at least some of the warm plumes aloft are getting our way instead of getting sheared and cut off to our south. EPS does try to erase the AK ridging and throw in a low around d10 so maybe we'll see the whole height field raise in the mid lats of eastern NAMER in response.
