I recall somewhat of a similar setup...forget there year but it was early 2010's. I think there was an EF-2 or even EF-3 around the Albany area which occurred with a supercell on the northern fringe of the warm front and they only had temperatures in the 60's. It was a crazy gradient with temps in PA near 90 and dews around 70. I remember chasing that day with my friend and we had gone into PA. Even though the temps were rather chilly the storm was drawing inflow from the southwest where instability was large
