Spring is just a week away, but winter weather may not be over yet on SouthCoast with more snow possibly on the horizon, experts said.

There is the potential of snow squalls late Wednesday afternoon as well as the potential of another system developing possibly Tuesday, the first day of spring, according to Bill Simpson, a meteorologist with the National Weather Service in Taunton.

"Weather models are hinting at it, but there's no guarantee," Simpson said. The timing of this potential system also could be off by 12 to 24 hours.

"Models have it a little further offshore," he said.

Simpson said Tuesday's nor'easter — the third in two weeks — left between 10 and 14 inches of snow on SouthCoast with higher totals in some spots. It did not surprise the National Weather Service or other weather experts though.

"It played out just as we thought," he said with bands of heavy, wet snow plummeting the region, at times snowing at the rate of 1 to 3 inches per hour. 

Even though March is associated with spring and the end of winter, Simpson said three nor'easters in two weeks is rare, but March snowstorms are not. "They are not as common as January and February. March storms are not that rare."

"It is rare for March not to have snowstorms," said M.L. Baron, a spotter with the National Weather Service and the operations manager of the West Island Weather Service.

"This was a textbook March nor'easter," he said, explaining all the ingredients came into place for a classic nor'easter, namely moisture, energy, location offshore enough to keep cold in place.

Through the weekend, there will be "more clouds than sunshine" with temperatures running about five degrees colder than 44-45 degrees, which is traditional for mid-March, Simpson said.
