Any flurries that occurred last night or this morning are essentially Long Island Sound or Atlantic Ocean effect as we have a SE wind off the water. This combined with some mid level energy is the trigger for the flakes. It is rare to see this as a SE wind often brings warm enough air for rain, but in this case, temperatures were just cold enough for light snow. As the breeze off the water brings more humid air to the coast, it is forced to rise as it encounters the terrain of Southern New England. A wind off the water also brings salt crystals aloft, which aid in forming precipitation via additional condensation nuclei. Much of the snow reported didn’t even show up on radar, but was there nonetheless!
