A few chances of snow, and colder than normal temperatures for the week ahead! Finally, winter is at least starting to settle in. It is amazing how quickly our ski season has taken shape in just the past two weeks! Our terrain has opened by 80% from where we were on the New Year. Temperatures will remain cold enough for snow making with even some natural snow in the forecast. Conditions should be great for the big Martin Luther King day weekend!
Our first chance of snow arrives today. Tuesday will start off dry, with even a little sunshine, but not for long. Clouds will be on the increase Tuesday withe a light Southerly wind pushing temps into the Lwr-mid 30's. An area of low pressure will track from the Great Lakes towards New England, with a weak batch of snow which will arrive in NH during the mid afternoon hours. It appears the first flakes will begin to fly around 3-5 pm.
While one low will track just to our north, a second low will begin to develop just off the coast and deepen as it moves into the Gulf of Maine and into the Canadian Maritimes. It looks like the low will develop just far enough east of NH to spare us any heavy snowfall... but as the storm begins to gather off the coast, snow will begin to fill in across the region during the evening commuter around 5-7PM. There will be the potential for a few heavier bands of snow and maybe even a few snow squalls during the evening hours. Any squall or briefly heavy band of snow will have the potential to create snow covered roads and slick travel. So expect conditions to quickly decline after sunset. Without the sun and cold temperatures in place it could get icy fast during the evening.
Luckily this will be a quick moving batch of snow which will help to keep accumulations to minimal amounts. Generally a widespread 1-2" of snow can be expected...with pockets of 3" possible. Across the north country, and also Carroll County, could see localized heavier amounts in any banding which could develop as the low deepens off the coast Tuesday night. A wetter mix will help to keep accumulations minimal near the coast.
The storm will deepen in the Canadian maritimes and wrap in gusty NW winds on the back side. This will direct a blast of colder air into NH with highs only in the 20's and windchills in the single digits and teens as winds could gust to 30+mph. A mix of sun and clouds will last Wednesday and Thursday with temperatures running slightly below the norm. High pressure from Canada will keep us dry into Friday, but we have to watch the weekend for another round of snow.
It is a while away and we are seeing a variety of solutions for the timing and the type of weekend precipitation. A similar pattern to today, with a low to our west and a developing low off the coast. This time, the storm may gather a little closer to the coast which would mean more significant impact. While temperatures will be cold enough to support snow, it will be borderline. There will not a be a huge supply of cold to play with. Winds will pick up from the ESE Saturday afternoon, and snow will likely begin to spread into the region and last into Saturday night. There are questions if the snow ends, or does it linger into Sunday because of a slow moving upper low. We will watch the trends on this. While we will be snowy, southern New England will be dealing with more of a wet mix. Several more inches of snow will fall from this disturbance by the time it departs Sunday. How much is still too early to tell. Colder air will follow in behind the snow with highs only in the Lwr-mid 20's Monday. Tuesday and Saturday snows along with cold sunshine and snow making....giving ski areas plenty to smile about in the coming days!
