Snow and bitter cold on the way for the weekend

By Adam Urquhart - Staff Writer | Jan 17, 2019

NASHUA – Forecasters have their eyes on a storm that has the potential to bring at least a foot of snow to Greater Nashua through the next several days, along with temperatures that could plummet below zero degrees Fahrenheit.

Doug Webster, senior meteorologist at Hometown Forecast Services in Nashua, said snow totals are still to be determined because forecasters are still not sure if the storm will stay all snow, or change to sleet or freezing rain.

On Wednesday afternoon, he said it is difficult to say. However, while speaking a few days ahead of the storm, he also said he would not be shocked if the forecast changes between now and then, as it often does.

The storm was just getting onto the California coast Wednesday afternoon, meaning the storm has yet to even be properly diagnosed by the models. However, prior to the weekend storm, Webster said there should be some snow tonight and into Friday morning.

“This is a timing thing that may occur during the Friday morning commute,” Webster said. “It may be slick for that, even though it’s a very minor event.”

After that snow has finished falling on Friday, he said colder air is expected to come in behind it, making for a chilly Saturday.

“That’s part of the key of how much of that comes in and gets ahead of that storm,” Webster said.

Webster said there will probably be some arctic air move across northern New England. In northern Vermont, New Hampshire and Maine, he said the temperature could be at or around zero during the day Sunday, while remaining much warmer at around 50 degrees in southern New England areas, such as Rhode Island and Connecticut. He also said where that really cold air settles in and drains in will make a difference.

“I would say that the minimum is at least several inches,” Webster said. “The question is, do we change to a mix or don’t we, or if we do, how long does it occur. It also may change back to snow on the back end of it too, which usually doesn’t happen around here, but it could in this case.”

Although Webster said it is really impossible to pin down totals this far in advance, he said it is likely the Nashua area will at least receive several inches of snow. He follows model trends, and the models run every six hours and each time, they may read something a little different.

When looking ahead at the beginning of next week, Webster said temperatures are about to dip down into the single digits.

“Following that storm, Monday and possibly part of Tuesday are going to be brutally cold, by far the coldest weather of the winter, by far,” Webster said.
