Clayton Stiver's 7-Day NH1 Forecast for Friday, Feb. 13, 2015
Source: Clayton Stiver
High pressure moves back in for Friday leading to sunshine. The high will keep fair skies in place through the morning hours Saturday. A decent dip in the jet stream will allow arctic air to move back across NH. Cold temperatures are expected from Friday through the beginning of next week.
Things look quite interesting for Valentine's Day PM into 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. Another significant snowfall can be expected for much of the Granite State with many seeing 6"-12" of snow with 12" or more possible for portions of Rockingham, Strafford, and Carroll Counties. Gusty winds will also make for blowing/drifting snow and reduced visibility (blizzard conditions possible for 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. Yet another storm system could potentially bring significant wintry weather to NH for Tuesday Night into Wednesday.
