The HRRR has a bias against stratoform precip, particularly of the lighter variety. I'm more worried about dry air ahead of the front than I am about model outputs
IF the soil moisture was drier I could see the possibility, but the general trend this season and the fact that most of the Midwest has been quiet wet, it'll be hard to drive temps that high. Who knows though, if that GFS Op run pops that 597dm ridge then it'll be FUEGO.
HRRR looks pretty underwhelming tonight and is catching up to the globals. Went from this
To this
In the space of a few runs. Pretty disorganized and meager looking stuff with this.
