With increasing clouds, and some showers or thunderstorms likely at times from late morning through mid-evening, expect a high around 80 today, with a wind turning out of the northeast at around 5 mph. While thunderstorms are obviously not guaranteed, most spots in central/eastern MA and southern NH will likely see something today.
The primary threat today is very heavy rain in thunderstorms, which may cause flash flooding. Storms have the potential to be strong to severe, with the primary threat for severe weather being strong to damaging wind gusts. Frequent lightning is also a threat as usual. Small hail is possible in some storms, though large hail is unlikely. The storm threat should wrap up toward the later evening hours with the bulk of the activity during the afternoon hours.
Have a great day!
