If it’s a weekend, then a storm must be on the horizon.
For the third weekend in a row, the forecast holds the possibility of a snowstorm, National Weather Service forecasters say. The storm would follow the Blizzard of 2013 two weeks ago and a smaller but still annoying snow last weekend.
The forecasters said in a weather discussion that supercomputer models of the weather are in “eerie” agreement and that confidence is increasing that a “significant coastal storm is possible” Saturday through Sunday.
The forecasters said that the snow could be heavier across the interior, while there might be a mixture of snow and rain along the coast.
Forecasters said there was a possibility of heavy, wet snow falling at a rate of more than 2 inches per hour, putting tree limbs and power lines at risk. But it also said the storm’s track could change.
The risk of coastal flooding is also increasing, the forecaster said, with the possibility of prolonged easterly winds.
David Epstein, boston.com weather blogger and meteorologist, said a storm will move north from the Gulf of Mexico while another storm over the Great Lakes moves east. The interaction of these two storms and their exact tracks are going to be critical, he said. He predicted a plowable snow event over northern and central New England, but said the forecast was uncertain along the coast.
Partly sunny skies are expected Thursday, with temperatues in the lower 30s to upper 20s. Seasonable temperatures and dry weather are also expected for Friday and early Saturday.
