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
Will still be quite chilly especially after the warmup.
Crazy heat SW US. Phoenix could have multiple 100+ readings and even Vegas approaching 100 in March, which is nuts. That's like us seeing 90s
Near 80F is like late summer warmth with the nearly September sun angle
Although the NAM shows some very strong sea breezes really cooling the coast down.
