The first of two storms to impact New England is on the approach. Precipitation will break out Sunday evening. Whether that precipitation will be winter or wet will depend on where you are in the region, as it has all winter long to this point. Here is the latest.
NORTHERN NEW ENGLAND IMPACTS
Northern New England is where you will find the snowstorm. Snow will be falling for basically the entire storm for much of the region. The exception will be the Maine coast and southeast New Hampshire, where mainly rain will fall. These areas will likely see some snow at the end of the storm, but by then, precipitation will be winding down, so only an inch or two will fall there.
There will be significantly more snow as you go north and west. There will be a jackpot strip of snow across the region. This strip will start in southern Vermont, head northeast into the White Mountains of New Hampshire and then continue northeast through central Maine to the Canadian border. This strip will likely see 5-8 inches of snow, with up to a foot possible close to the Canadian border in Maine.
The snow will be the wet, heavy and sticky variety. This could cause some power problems in the areas forecast to get the most snow with weighted branches. Winds will also gust as high as 40mph. While 40 is not quite damaging on its own, combined with the weight of the branches, could cause more problems. The snow will be fluffier at elevation.
In the areas that will see rain, a half an inch to an inch is possible. There is also the risk of some coastal flooding during the Monday high tide. This risk has decreased some as the storm has trended weaker. Minor coastal flooding will remain in the forecast.
NORTHERN NEW ENGLAND TIMING
Sunday evening: Snow breaks out in southern Vermont and southwest New Hampshire; cloudy elsewhere.
Around midnight: Heaviest snowfall rates for much of the region, rain falling in southeast New Hampshire and Maine coast.
Monday morning: Snow, rain continues across the region, heaviest snowfall rates for eastern Maine.
Around noon: Precipitation starts breaking up in Vermont and New Hampshire, steady snow continues in much of Maine, southeast New Hampshire starts snowing.
Monday afternoon: Snow continues in Maine, snow makes its way to the coast.
Monday night: Storm pulling away, drying out across the region.
SOUTHERN NEW ENGLAND IMPACTS
This will primarily be yet another winter washout for southern New England. Much of the region will see a widespread inch of rainfall. The exception will be the Berkshires of Massachusetts and the Worcester Hills, where snow will likely accumulate. 4-6 inches of snow is possible in the Berkshires and a few inches in the Worcester Hills. There are still discrepancies among weather models on just how much snow will fall in these areas.
The threat of damaging winds is decreasing. While winds will still be gusty, the ingredients are not coming together for damaging winds. On top of this, the storm is trending weaker as it makes its pass near Cape Cod. The NWS states:
"Strong, potentially damaging winds are looking like less of an issue given an offshore track of the low level jet and a fairly inverted sounding profile. However, we will have gusty N/NE winds on Monday morning."
Like northern New England, the prospect of coastal flooding exists across the Massachusetts coastline. Only minor flooding is expected at this time, but it will be something to pay attention to on Monday afternoon.
The areas that see mainly rain will again likely see some snowflakes fly at the end of the storm Monday afternoon. This could accumulate up to an inch or two across the region, with the exception of Cape Cod.
SOUTHERN NEW ENGLAND TIMING
Sunday afternoon: Rain breaks out in Connecticut.
Sunday evening: Rain spreads across Massachusetts and Rhode Island, snow falls in the Berkshires and Worcester Hills.
Around midnight: Peak snowfall and rainfall rates
Monday morning: Snow, rain continues.
Around noon: Precipitation starts to become lighter, snow showers are more widespread.
Monday afternoon: Light, spotty precipitation continues.
Monday night: Storm pulling away, region begins drying out.
