Crossing my fingers for some severe weather action tomorrow, as you all know this year has been a real bummer for that. Looking at the models, seems like CAPE values are going to be crazy (as high as 3,000 J/kg in some places), but seem to be lacking severely in wind shear, so I'm not expecting storm organization to be that great. SPC has also slapped on a 5% Marginal risk for the Lower Great Lakes tomorrow.
