On the subject of DP's and the surface, they rise really fast on the GFS. So, all the cooling is over in my locale by 1PM on Sat. A tad later on the CMC and Euro. So, they help at first but of course when it is saturated, we are going to need help from those rates pulling down some of that sweet, sweet upper 20's and low 30's 850/925 temps (non Euro) to keep us cool....almost like a nuclear reactor.
