Clayton Stiver's 7-day NH1 Forecast for Friday, Nov. 21, 2014

A cold front tracks to the east of the Granite State Friday as another shot of arctic air builds in across the region. With high pressure building to our south, fair skies will be seen, but the pressure difference between the high to our south and an area of low pressure to the north in Canada will create gusty winds making for low wind chill values.
The high pressure system will slide off the east coast for the weekend allowing a return southwesterly flow of wind to usher in warmer air. The warm-up won't be too noticeable Saturday thanks to such a cold start to the day, but by Sunday, more seasonable air will have taken over. A weak upper level disturbance may clip the Great North Woods Saturday with some snow showers.
Low pressure will track out of the Midwest and across the Great Lakes Monday pushing a warm front across the Granite State Sunday Night into Monday Morning. This setup looks to spread a decent shot of rain across the area overnight Sunday into Monday. At the same time, a strong southerly flow of wind will pump in a mild air mass to the region.
A cold front will then slowly track through Monday Night with a seasonable air mass returning to the Granite State. A fairly dry air mass also looks to settle in for several days leading to quiet weather.
