That humidity which has been so high the past several days is finally starting to go down and will continue to fall throughout the day today and into the evening. We have reinforcing shots of drier air moving in from Canada and this is going to set up a wonderful weekend with plenty of sunshine, low humidity and comfortably warm temperatures.
This is the first weekend the sun will set before 8 p.m. since May and we are continuing to increase the rate at which we lose daylight. The angle of the sun is also getting lower each day. This isn't to bum you out — just a fact of August. As the shadows grow, we will have mornings where it will feel cool for an hour or two.
When you get up Sunday morning, there will be a touch of fall in the air just for a short period of time before temperatures quickly rebound. Even by 8 or 9 a.m., it's going to feel like summer once again.
The only chance of showers I see would be Saturday afternoon north and west of Boston and into northern New England’s hills.
It turns warmer for Monday and Tuesday before another shot of cooler air moves in for the second half of next week.
