Forecast discussion: The good weather continues in Southern New England, thanks to a high pressure system over the western Great Lakes. This high will continue to protect Boston and the rest of eastern Massachusetts from any storm systems for the week ahead, as any storm systems move off to the south and east.
However, we will begin to feel the dog days of August once again by early next week. As the high pressure system moves off to the east and into the Atlantic, winds will continue to remain from the southwest. This will allow for more moisture from the Gulf of Mexico to move up into the atmosphere. So, temperatures will slowly increase, as the dewpoint temperatures increases. The humidity will increase, and the air will become muggy once again. High temperatures will slowly climb into the middle to upper 80’s by Tuesday. We may reach 90 degrees in some areas on Thursday.
Meanwhile, Tropical Depression Erin was centered at 17.7N 33.3W as of 5 p.m. EDT on Friday, or about 625 miles west southwest of the Cape Verde Islands. Maximum sustained winds around the center were at 35 mph and was moving west-northwest at 17 mph. Erin is forecast to remain at depression strength, due to some wind shear it will encounter. Despite the warmer water temperatures, this shear will not allow the tropical to strengthen. The system will continue to move towards the west-northwest and northwest over the next several days.
