The GFS 2m temps have been improved from last year. I mean it was trying to lop 20C onto the 850s last year to produce 110F 2m temps. Of course dews ended up overperforming as well which limits your heating potential. So 100s really didn't have much of a chance.. 22-23C with W flow and good mixing would get it done though barring 75-80F dews. It's all kinda moot except for the weenieness that is actually the century mark. If we were a celcius country we probably wouldn't oooh and ahhh until the temp hit the elusive 40C (104F). Anyway, it'll be brutally hot in some way, shape, or form. Whether it's 98F or 101F or 95F/77F.
