After the surprise Ocean Effect Snow in New Jersey the other day and talking about how unusual it was, another unusual event happened today! This time it was sound effect snow from Long Island sound.
As this week's nor'easter slowed down and te upper level low caught up to it, we have seen the cold air and moisture wrap all the way around the storm. Even to one point where it was raining in Maine but snowing ins Philadelphia!!!! Crazy!
As this storm has sat and spun over us, the winds have shifted from the north east to the west and even south west. Usually this wind direction brigs warmer and drier air but being stuck under the trough of low pressure, with all layers of the atmosphere being close to or bellow freezing, there's been NO warming.
With this south west wind, cold air and relatively warm Long Island Sound, a very faint snow band formed over the sound north into Massachusetts. The wind direction was perfectly aligned with the length of Long Island sound, creating enough fetch and warm water to form the snow showers and flurries.
I've circled the sound effect snow band on the radar image below. It's faint compared to the ocean effect snow from earlier this week and nothing compared to the Buffalo lake effect storm from November 2014 but it's still very interesting!
