Clayton Stiver's 7-day NH1 Forecast for Wednesday, Jan. 7, 2015
The jet stream will remain well south of NH for some time keeping below normal temps in place for a while. At the same time, no real strong storm systems are expected to impact the area.
An arctic cold front will track through Wednesday bringing some flurries and snow showers. Some localized bursts of heavy snow are possible bringing a quick inch or two of snow with whiteout conditions and icy roads. Some folks will stay completely dry. The front will usher in the coldest air mass of the season by Wednesday Evening. Gusty winds and very low temperatures will make for dangerous wind chill values Wednesday Night into Thursday Morning, anywhere from -20 to -45, the coldest values being across the Mountains and Great North Woods.
High pressure builds in from the west Wednesday Night and crests across the region Thursday. Low pressure will move east across Southern Quebec late Thursday into Friday dragging another cold front across the region. Again this could bring some snow showers and snow squalls.
High pressure settles in for the weekend into the start of next week making for quiet weather. An ever so slight warming trend will start to develop.
