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.
