The upcoming heat wave will not fit that description... but the weather has been near perfect for all of July and fires on the other side of the mountains are to be expected at this time of year.
18Z GFS is certainly not backing down... and maybe extending the heat. We will be in Minnesota one week from today... looks chilly there while its baking here.
New 12Z ECMWF surface map does show mostly sunny skies for everyone by 5 p.m. but it will probably take until mid to late afternoon to really break up.
