NH1 7-Day Forecast for Sunday March 15, 2015
Winter Storm warning in effect for Coos and Northern Carroll counties until 5pm Sunday. A Winter Weather Advisory is posted for the rest for the state until 5pm Sunday.
Low pressure will be strengthening east of the region today and as it does so it will draw down colder temperatures and additional moisture as a weak disturbance comes down from the northeast behind the departing storm.
For northern NH that means snow will continue throughout the day, possibly heavy at times then tapering off to snow showers before ending during the late afternoon.
For southern NH that means any morning rain showers will change to snow showers and then a steadier light snow continuing into the midday and afternoon then taper off during by the early evening. This will result in an inch or two of accumulation from Manchester to the Monadnock region down along the MA border to the seacoast. From Concord to the Upper valley and over to the Lakes region we can expect 2-4 inches of snow, while the mountains into the Great North Woods 4-8 inches will fall. Some of the higher mountains will pick up a foot.
High pressure settles back in for the start of next week with more seasonable temps returning. A cold front tracking through Monday Night into early Tuesday could spark some rain showers then some snow showers during the day Tuesday. Unseasonably cold temps will return for the mid to late part of the week but high pressure will otherwise make for fair skies.
Sunday: periods of snow, highs 31-35. Monday: Mostly sunny, highs 38-43. Tuesday: Partly sunny with a threat of am rain shower, highs 35-40. Wednesday: Mostly sunny, cold, highs 27-30. Thursday: Sunny, highs 36-40. Friday: Mostly sunny, highs 40-45. Saturday: threat of snow showers, highs 36-40.
