This is pretty cool stuff for a weather geek. Take a look at the echoes racing west across Long island Sound. That is a backdoor cold front with a strong wind shift behind it and rapid temperature drop. The wind at Bridgeport is north at 15 mph and the temperature is 78º while the wind in Groton is southeast gusting to 32 mph and the temperature is 62º!
There’s another front on there and that a sea breeze front that has developed basically over New Haven Harbor and extends northeast into North Branford, Durham, and Killingworth with southerly winds behind it and northerly winds ahead of it.
One of the reasons the backdoor front has taken on a “C” shape is that less friction over the water has allowed the winds to be faster over the Sound than over land which is effectively bulging the front west in the water.
The echoes to the west over New York are showers falling from a mid level cloud deck that are evaporating before reaching the ground.
