NH1 Weather Insider with Joe Joyce: August 27, 2015

Well that feels better! The humidity has finally passed! After over a week with dewpoints in the 60's, a more comfortable airmass has settled in across the Great Lakes to the Northeast. The dry air is coming with seasonally cooler temperatures and the feel of Autumn, especially during the evening when lows will be dropping into the 50's. Very cool and crisp air will greet the early morning risers this Thursday & Friday. Cooler air aloft will still be sitting over us Thursday. So even though the day will start with sunshine, I do expect some building cumulus clouds during the afternoon, and even the chance of a spot shower or sprinkle in the mountains. Sunshine will be brighter and longer lasting at the beaches. Most areas across NH will spend the day with temps in the 70's to near 80. As the cool pool air above our heads begins to pull away, a more stable airmass will arrive by Friday with building high pressure (sinking air), warmer air aloft, and Sunny skies with highs in the 70's to near 80.
The weekend will start off fine, but high to-mid level clouds will be increasing Saturday. Partly sunny skies or filtered sunshine should be expected Saturday with warmer winds from the SW which will help to direct a warmer feel to the air with highs in the Lwr-mid 80's. A weak front will sag into New England Sunday which could trigger an afternoon shower. Otherwise, I would expect more partly sunny skies and highs in the mid-80's.
A significant upper level ridge will begin to shift into the Northeast starting next week. This will allow the heat and humidity to return. Highs Monday through Wednesday will average above the norm with highs in the mid-upper 80's nearing 90. Some areas may even come close to stringing together a heat wave! The normal high is 79 so we will be well over that. In fact, the first 2 weeks of September are looking very warm for the eastern third of the country, which includes us! If the upper level flow has anything to say about it, we could be seeing a very warm September ahead, which would be just fine for all the summer lovers out there who are currently suffering from depression as the summer season is quickly winding down.
In the tropics, things are firing up! We are watching Tropical Storm Erika who has been encountering some upper level wind shear slowing down the rate of intensification. This will be the case for the next several days. The storm should begin to strengthen as it nears the US coastline of Florida. The latest info is this stronger storm will likely stay just off the coast of Florida and drift up the coast towards the Carolina as a moderate storm. It is impossible to say where this storm will end up, but it is our job to remain aware of where this storm is heading and to make your places accordingly to keep your family safe. It is critical to pay close attention where this storm will eventually end up. Keeping the boat safe and out of the winds could mean the safety of your team.
