It's like Mother Nature flipped a switch. From a record cold start to the year with temps struggling to get out of the 40's as late as April to 80's and humidity by early May. The northeast springs are not the best seasons, especially if you live near the water. However, this spring has transitioned even faster than normal.
With the warm, summer-like temperatures occurring on a daily basis over the last week, it has had some impacts on the otherwise boring weather. Since the waters of Long Island sound are still chilly from a very cold winter, a temperature imbalance is experienced every day. This imbalance results in fog!
As the temperature heat up over the land, it allows dew points to rise slightly. Then as the temps drop of considerably at night or as the sea breeze kicks in, the temp hits the dew point and fog is formed. This usually occurs at the coldest part of the day, which is a little after sunrise.
The fog usually begins out over Long Island sound and the Atlantic, where the temperature difference is not as great and then works inland.
Below are photos I took during a run to the beach in Milford, CT on one of these days. When I left my house, which is about a mile away from the shore, the fog had broken up and the sun was breaking through the clouds making it quite uncomfortable. As I got closer to the beach i could feel the cooler breeze and soon I could see the fog bank off the coast and along the shore.
