With the outflow boundary out racing a lot of the convection, this has probably ended any scattered or widespread risk for wind damage. Looks more like generic thunderstorms for the rest of the evening.
Looks like the Greencastle storm died, threw an outflow boundary south into Maryland, and it's about to crest the Catoctin Mts. Wonder if that's what kicks off the activity in the lee of the mountains and northwest suburbs this afternoon?
Latest SPC mesoanalysis has an axis of ~2,500 SBCAPE in southern PA. Wonder if the southern edge of that enhanced CAPE might act as a boundary for the northern and western crew later?
Yup. That is the cell I was referring to. Would love to be up in Cascade, MD looking at this from their overlook. One of the prettiest places I've every been.
Thus far, the best cell of the day appears to be running just north of Mason-Dixon into PA. Consistent CG, tops sustained about 35,000 feet, and now some damage reports coming out as LSRs via CTP.
If you really want to see something depressing, check out the consistently large data gap of 00z/12z RAOBs across the intermountain west, desert southwest, and upper plains. Watching the US upper air network get decimated willy nilly is just a sight to behold.
