NH1 First Alert Weather: Bitter cold returns to NH this week
Milder air continues for one more day, before a blast of arctic air moves in for the middle of the week.
Tuesday will bring some early sun, but then the sky will become partly to mostly cloudy. A spot rain or snow shower can't be ruled out to the north during the afternoon. Highs will be in the 40s to near 50 degrees. The cold front will move through Tuesday night. Out ahead of it, a few more snow showers or squalls are possible overnight, especially in the northern half of the state.
The wind will start to pick up early Wednesday and temperatures will stay steady, or drop some during the day. Some northwesterly gusts to 40 mph are possible on Wednesday.
High pressure builds in for Thursday. The forecast turns much more uncertain from Friday into the weekend. Mild air will attempt to build into the region, but cold air may be stubborn and tough to budge. A period of some wintry weather with cooler air is possible, especially Sunday or Monday.
