NH1 First Alert Weather: Scattered Showers, T'Storms Wednesday

NH1 Chief Meteorologist

Heavy rain in the north and west mountains & valleys overnight with localized flash flooding. Wednesday will still be an unsettled day as the best dynamics for scattered showers and periodic storms remaining over the forecast area with a stalled front. Not everyone will get into the heavy rain. Showers will be scattered, but any slow showers could come with some heavy rain along with it. Highs will be mainly in the 70s and Lwr 80s.

A westerly flow will develop both at the surface and aloft for Wednesday night, returning a more continental airmass to Maine and New Hampshire with clearing skies and falling humidity. The wind may not be sufficient enough to prevent some patchy fog from forming, especially in areas that received heavy rainfall Wednesday.

Weak high pressure returns on Thursday with sunny to partly sunny skies as clouds will have a tendency to build with the heating of the day. NW winds on Thursday will warm temps into the mid 80's by aftyernoon. The next hazardous weather threat? Low. Friday will be another sunny warm day in the 80's, but a few thunderstorms are possible later Friday afternoon into Friday night along with another cold front.

Friday night into Saturday the upper level low will push eastward driving a surface front and rain into the region. With the front passage timing overnight at the moment, thunder is less likely but a few rumbles are still possible. Saturday westerly flow develops behind the front with generally clearing conditions. Temperatures will be slightly cooler in the mountains but the most noticeable effect of the front will be a drop in humidity through the day on Saturday. Sunday will be sunny to partly sunny and drier again with high pressure building in for the start of the week. Just beautiful weather near 80-85 degrees. A seabreeze will take over during the afternoon keeping temperatures cooler along the water. July 4th will have plenty of sunshine and comfortable air as well with highs in the Lwr-mid 80's. Next week is showing signs for a warm pattern to be developing across the nation as a whole. Plenty of more legs left to this summer! Make the best of it!
