Clayton Stiver's 7-day NH1 Forecast for Friday, Dec. 19, 2014
Source: NH1 Chief Meteorologist - NH1.com
High pressure will settle in for Friday and remain locked in place through the start of next week leading to quiet weather. A north to northwest flow of wind and a dip in the Jetstream will make for temps around or just below normal for this time of the year. A bit of an onshore fetch of wind Sunday could lead to some snow showers for the Seacoast, but little or no snow accumulation is expected at this time.
A weak area of low pressure will likely strengthen and pass to our west Tuesday. This system looks to spread light precipitation across the Granite State. Inititally, a northeast wind will lead to cold temps at the surface which allows for light snow. The low will push a warm front through however leading to a southerly wind and warmer air building in. As it appears now, this will allow for a change to sleet and freezing rain, and eventually all rain. Again, it appears at this time that amounts with this system will be light.
A stronger area of low pressure looks to develop and strengthen to our west for Christmas Eve. This setup has the potential to bring heavy rain to the Granite State along with a surge of mild air and gusty winds. These conditions could linger into Christmas Day Morning, then gusty westerly winds bring dry air in to clear the skies out throughout the day.
