Clayton Stiver's 7-day NH1 Forecast for Tuesday, Dec. 30, 2014
Source: NH1 Chief Meteorologist - NH1.com
A broad dip in the jet stream will remain locked in place across the Granite State and the Northeast for much of the week. This setup leads to more seasonable, and even below normal temperatures. At the same time, high pressure at the surface overall keeps things quiet.
High pressure settles in from the west for Wednesday. A cold front will approach from the west on Thursday and will stall over the region on Friday. This front looks to be a dry passage. The front will gradually sag south of the region Friday Night as high pressure builds in from the west. This high pressure system will crest over the region Saturday and provide a northeast wind to re-inforce a seasonable cold air mass.
Our weather finally looks to get a little more interesting late Saturday Night into Sunday as low pressure and a series of frontal boundaries track up from our southwest. Initially the air mass looks to be cold enough for snow late Saturday Night/early Sunday as the moisture overspreads the northeast flow at the surface. The low track however looks to be to our west meaning a south wind and warm air eventually take over. This will transition snow to sleet and freezing rain and eventually plain rain by Sunday Morning Sunrise which could be heavy. This forecast is still very much subject to change so stay tuned!
