A double-barreled storm could drop up to a foot of snow on southern New Hampshire.
Meteorologist William Watson, of the National Weather Service’s Gray weather station, said snow will likely start late Sunday and continue through Monday morning. Another wave is expected on Monday afternoon, into the night.
The seacoast might get a little rain mixed with the snow, Watson said.
Laconia and Plymouth will get four to five inches of snow, he said, while Concord might see eight inches. In Manchester, forecasters predict about 11 inches of snow, and towns along the Massachusetts border could get a foot.
After the second wave of snow, temperatures in New Hampshire will likely stay below 40 degrees — too cold for much of the snow to melt.
“This might be the start of our snow pack,” Watson said. With no rain or warmer temperatures expected for another week, the snow might last.
Watson cautioned that the second wave of the storm could fizzle before reaching New Hampshire, so there is a chance there could be less snow.
No matter how much snow falls, winter parking rules will be in effect in Manchester as of 1 a.m. Sunday. On streets with parking on both sides, cars must be parked on the even-numbered sides of streets in December, before switching over to the odd-numbered side on Jan. 1. In snow emergencies, no parking is allowed on the street from 10 p.m. until 6 a.m.
