NH1 Weather Insider with meteorologist Bill Gile for Sept. 8, 2015
High pressure still to our south and east continues to pump in the heat and humidity. For many folks in southern NH it'll be 3 days of 90+ temperatures making it an official heat wave.
In northernmost NH Tuesday a frontal boundary will be draped along the Canadian border will drift down from Canada creating a bit of cloudiness and a scattered shower or thundershower. Otherwise, south of the lakes region we'll see more and more sunshine prevailing as you head down into MA. While it will be humid statewide, actual air temperatures will vary ranging from the mid 80s up north in the clouds to mid 90s in southern NH and northern MA in the sunshine!
Another hot, humid day will be on tap for Wednesday then a cold frontal system will finally move in for Thursday with thunderstorm activity that will break the heat and humidity. This will be giving us cooler air by week's end with highs only in the 70s. Some of the developing storms could become quite strong Thursday and a few showers will be lingering into Friday and then slowly dry up into the weekend. We really could use the rain since we've been in such a dry pattern lately and rainfall potential from the storms could produce 2 inches of rainfall.
Have a great week!
