Clayton Stiver's 7-Day NH1 Forecast for Saturday, Feb. 14, 2015
Source: Clayton Stiver
Fair skies remain through Saturday Morning as high pressure moves offshore. A decent dip in the jet stream will allow arctic air to filter in across NH. This arctic air will stick around into the beginning of next week.
We continue to track a significant snow storm for the Granite State from Saturday PM through Sunday. Initially, another "clipper" system will swing through, but this time, it will slow down just off Cape Cod and rapidly intensify as it moves north-northeastward. This storm will build into a major Nor'Easter as it moves through the Gulf of Maine and the Canadian Maritimes. Many across NH can expect to see 6"-12" of snow with 12" or more possible for portions of Rockingham, Strafford, and Carroll Counties. Folks right along the Connecticut River may see more on the order of 3"-6" of snow. Gusty winds will make for blowing/drifting snow and reduced visibility (blizzard conditions possible for eastern portions of NH, especially the Seacoast). Minor coastal flooding and beach erosion will also be possible a few hours either side of the 7am high tide on Sunday.
High pressure will once again settle back in for the start of next week leading to quiet weather. Another storm system looks to track up the eastern seaboard Tuesday Night into Wednesday possibly bringing yet another accumulating snowfall although much uncertainty remains with the track of this system. High pressure brings sunny skies Thursday and Friday but cold air comes with it as well.
