NH1 Weather Insider For Wednesday July 15, 2015
NH1 Chief Meteorologist
A cold front is on the move on Wednesday! A mild humid start to with temps near 70 at dawn. Some patchy in the valleys and at the coast during the early morning hours. Mostly cloudy skies will dominate the morning as a the front pushes towards the coast by the midday. The best chance of showers along this front will come during the late morning into the afternoon across southern and SE NH. The seacoast will see a showers linger in the afternoon, with even the potential for a thunderstorm. Meanwhile, farther inland skies will become brighter during the afternoon with falling humidity across northern and western NH.
Skies will be clearing Wednesday night as cooler and more comfortable air comes rushing in with a breeze from the NW. High pressure will sit over us with light winds and sunshine Thursday with highs in the 70's. High pressure slides south of New England Friday with high clouds increasing. Highs still in the 70's and Lwr 80's.
The weekend remains a bit tricky in as there are questions on how cool or how warm it will be. Wind direction, and the amount of cloud cover, precipitation will play a major role in determining if we stay in the 70's or climb into the 60's. Low pressure will be tracking into the Great lakes Saturday. A warm front will slide into Northern New England. Scattered showers and T'storms could erupt along this front during the afternoon. While mos of the day should be fine, clouds and humidity will increase. Any showers or storm could come with a heavy downpour during the afternoon.
The front will stall over us Sunday with partly sunny skies and the risk for another pop up scattered shower or thunderstorm during the afternoon. I expect a warmer feel for the weekend with highs in the lwr 80's. If an onshore wind becomes established ahead of the front we are in the 70's. If the front stays just west of New England, highs could climb into the mid 80's. It is a very close call. I have split the middle in the Lwr 80's for now. A cold front will push towards Monday and Tuesday and will become a trigger for more periodic showers and thunderstorms. Some of these may be stronger storms and come with heavier downpours.
