Is this a wishcast, especially using the 18Z NAM? You bet!! It IS November after all, so that’s about all I have to cling to. First, the 700 mb vertical velocity chart at 18Z Saturday:

namSE_700_vvel_048And now the supercell composite parameter at the same time:


Low instability values prevail while shear is off the chart. Vertical profiles look pretty wet as well so a low overcast will inhibit visibilities.

So am I excited? No. Will I keep an eye on Saturday’s setup? You bet!
