Details on the Nor'Easter Set to Impact the Granite State the Next Few Days

Source: NH1 Chief Meteorologist -

A bit of everything on the way for the Granite State over the next couple days. With an area of low pressure moving up the east coast and parking itself over Long Island, this will draw in warmer air from the Atlantic which sets the stage for a transition from snow to rain.

This storm system looks to be with us through Thursday, but the most significant impacts with snow, ice, rain, and wind will come Tuesday Afternoon and Tuesday Night. Folks across the higher elevations from Monadnock up through western reaches of Hillsborough and Merrimack Counties, the Upper Valley, northern Lakes, and points north have the best chance to see a heavy wet snowfall which combined with gusty winds could lead to power outages. Amounts of 3"-6" and 6"-12" will be possible in these areas with the highest amounts from the Upper Valley through the Mountains and Great North Woods. Even here I expect the snow to eventually mix with and change over to rain, especially once we get to Tuesday Night. In the middle of that transition, there could be some freezing rain which may lead to ice accumulation on the order of 0.10"-0.25" Elsewhere ice accumulation doesn't look to be as big of a deal.

If that wasn't enough, there's a heavy rain aspect to all of this which could lead to flooding. Folks from the Merrimack Valley and points south and east will see the longest period of plain old rain which looks to be on the order of 1"-2" with locally higher amounts. With the frozen snowpack on the ground, the ground will have a tough time absorbing the rainfall. This leads to runoff issues with urban and poor drainage areas needing to be on the lookout especially for flooding. Coastal flooding and beach erosion will also be a concern for the Seacoast, especially Tuesday Afternoon.

Look for gusty winds, perhaps over 40mph, for Tuesday Afternoon and Tuesday Night. The Seacoast will see the strongest winds.

Primarily rain showers are expected for most Wednesday, then we could see a change back to snow showers on Thursday. This activity looks to be light at this time so I'm not anticipating big accumulations there. I will still be monitoring for any changes regardless so stay tuned!
