Only a matter of time before we get some of those prolonged ridges here. Doesn't take much. Our first warm-up last week set record highs here and the earliest 80F at NYC.
This region really has some cooler force field over it. The rest of the country will turn ridiculously warm and stay that way.
SW US has Phoenix pushing 105+ and Vegas 100+ next week. GFS OP shows a ridiculous warm/cool gradient LR
