You had some sun before us and that can upset stable stuff and the 70-80kn winds are at 2-3k so doesn’t take much to mix them down. I don’t doubt that guesstimate at all.
Won’t take much to tap into the jet overhead. It is screaming.
Wind advisories up too for Dauphin, Lancaster, Lebanon and York counties. 15-25 mph with gusts to 50.
Not sold on much severe in the LSV Sunday - clouds might not let anything destabilize. But the winds will still be fierce and a squall line can still occur even if not officially severe.
I don't know the true definition of a derecho, but this evening in Missouri/Iowa/Illinois seems like a derecho event is going to occur.
The sun just broke out here finally at 3, where it's 53.
Sunday looks kinda rough, esp the more S/E you go in PA. But even if you miss the QLCS, very strong S winds will be an issue.
