NH1 First Alert Weather: February Snow Blitz!

NH1 Chief Meteorologist

On Saturday...the light snow will fall through the morning hours. Weak low pressure will develop over the Gulf of Maine Saturday morning with the onshore flow could help to enhance snow amounts somewhat near the coast... The snow should taper off over New Hampshire by afternoon Amounts will be in the 1 to 3 inch range... Otherwise...a mainly cloudy afternoon and evening as we await the arrival of a much more significant storm system on Sunday.

A high impact snowstorm is likely for Sunday into Monday with heavy snow for most if not all of the region, along with gusty winds. The snow may mix with rain for a while on the coast before the low really gets cranking off the coastline Sunday night. This could present a problem along with heavy wet snow loading on trees and power lines near the coast. The result could be power outages when combined with strong wind gusts. Speaking of winds, but late Sunday night and Monday morning, gusts of 30 to 45 mph will be possible with the highest gusts on the coast. The result may be a period of near-blizzard conditions during this time at dawn Monday. One limiting factor to blizzard conditions is the snow will be wetter on the coast for a longer period of time which reduces blowing and drifting.

The timeline goes like this. Sunday will start off cloudy and quiet. Snow will be filling in quickly Sunday morning, with a steady snow in place for the midday.

Some warmer air will try to mix in during the afternoon with possible a change to rain at the coast. Tough call for the seacoast at this time. This will make for lesser accumulations at the coast and a heavy wet snow just a bit farther inland. Snow become heavier inland during the afternoon Sunday.

Heavy Snow Sunday Night as the low tracks south of New England and starts to become a stronger storm. This will have any rain changing back to snow even at the coast.

By dawn Monday morning, Whiteouts, cancellations, snow bound roads and gusty winds as the low bombs out in the Gulf of Maine. Snow can be expected for much of the morning but the heaviest will be over. Snow will be tapering off during Monday afternoon as the storm pulls away.

An early estimate of the amount of snow we are expecting. The coast remains the tough call at this moment until we get an bit more information in. Heavy snow across the the state with much of eastern New Hampshire seeing a foot or more of snow. Maine will likely see jackpot amounts of snow.
