ARCTIC COLD! Oh yeah! Now this is New Hampshire winter! Temperatures are starting off near zero at dawn across much of the state. In the north country, morning lows will be below zero. The coldest air of this early winter season sits over us this morning, with high pressure just to our west. Sunshine with highs climbing back into the Lwr-mid 20's by afternoon, with a light wind from the NW. The wind chill factor will not be as much of a factor, though any breeze will make it feel colder. It will be another clear, cold, calm night Tuesday night, just not as cold as Monday night. Lows will still drop inot the single digits overnight.
High pressure south of New England for the midweek will wrap in a milder WSW wind flow allowing temperatures to moderate into the 30's and Lwr 40's. The cold pool of Arctic air will lift away, and temperatures will even average above normal for the rest of the week in the sunshine through Friday.
The weekend becomes more complicated as there are a few pieces of energy/moisture to track. We will also have to watch the temperatures in place in front and during the moisture's arrival. A warm front approaches Saturday starting off as a burst of snow in the morning, which will likely mix over to some rain in southern NH and at the coast. There will be a better chance of light accumulating snows across the NW interiors of the state. The warm front will take all day to push through, with the mixed back likely winding down Saturday night. It does not look very heavy, but it could get slick where it remains all snow.
The second batch arriving later Sunday is a bit more in question, as there are a variety of solutions. It will likely be the more significant batch of moisture. A cold front will approach later in the day with the potential for a stronger low to develop along that front. This could bring another batch of rain and snow to the region and will be winding down Monday morning. Again, the best chance of of accumulating snow will be in the NW portion of the state with more mixing with rain at the coast. But again, it is so far away, it is impossible to have much confidence. on how exactly this will play out. These are simply general ideas of how the weather is looking in the longer range without getting into too specific details.
Speaking of long range, a much colder pattern awaits for next week Jan-12th-17th with a persistent trough from the Great Lakes to the Northeast. Cold air will be spilling from the Arctic right into New England with below normal temperatures. No big storms from now through this time period, BUT models are hinting at a larger storm forming somewhere of the mid-Atlantic coast around the 17th or 18th..We'll see....
