I was on the mid cape driving between Barnstable and Yarmouth at about 615 and I saw a blue green flash that I thought was a transformer. It wasn’t windy and only a couple inches of snow so it wasn’t a power outage. I’m now thinking lightning/thunder snow. Any way to check for strikes around that time and location. I was pretty focused on the road and not the time so it was 550 to 630 pm. On a side note I saw 4 accidents and the roads were horrible.
