That's what you call LAKE EFFECT! We see all sorts of fucked up weather. Last week we had 15 inches of snow and 20-25*F and 3 days later it was up around 55F and all of the snow melted. Now it's back down to a brisk 28F with a wind chill of around 15F. They only seen 4 inches of snow up in Johnstown Pa with is 1 hour NW of us up on top of the mountain.
Those rippled clouds are rite above me. Look at some geological and elevation maps of the same area it explains alot. We're on the most south eastern edge of a large mountain range. We get hit from weather up out of Baltimore Maryland and the nasty cold crap from the lakes. They combine just above us as the cold rolls down off of the mountain range and the slightly warmer and wet air comes in low and slams into the side of the mountain. It causes a rippling low pressure zone which can cause higher than normal precipitation and higher winds than it would just a couple of miles north of south of us.
The mountain just above us is the tallest mountain at 3,128 feet above sea level from here to the ocean. There are a couple "hills" between us and the ocean with sharp peaks up to 2,400 feet but no mountain ranges that high.
Overlay this and have a look.
