Here’s David Epstein’s forecast for the first weekend of August

Expect warm temperatures but not excessive heat.

The dew point is finally dropping in the northern sections of Massachusetts, but the weather remains relatively muggy across the Cape and islands.

Here’s your complete forecast for the first weekend of August.

Friday is warm and dry.

Highs Friday will be in the 80s in most areas. —WeatherBell

Closing out the work week, Friday will feature a lot of sunshine and warm temperatures everywhere. There’s virtually no chance of showers. 

High temperatures will be in the 80s in most areas. There will be sea breezes along the coastline in the afternoon.

If you want to escape the humidity even more, head into northern New England, where it’ll be much dryer this weekend.

Saturday brings warm temps and notable humidity.

Temperatures continue to be above average well into the 80s. Although we are past the peak of this summer’s readings, we will still be above average for the foreseeable future. The humidity will be notable; it’ll be highest across the south coast and lowest and most comfortable into the mountains of northern New England.

I can’t rule out a quick isolated shower or thunderstorm, but 90 percent of you will see nothing at all. I’m just mentioning it in case it happens.

The humidity declines Sunday.

It will be very warm on Sunday with more humidity. —WeatherBell

Temperatures remain warm on Sunday with some upper 80s starting to show up along with a decrease in humidity, especially late in the day or at night.

Just like Saturday, most of us will not see any precipitation, but there is a nonzero chance of a pop-up shower or thunderstorm in the afternoon.

Next Week

More summer warmth is likely for much of next week. Monday will be the most comfortable day in terms of temperature and humidity with an increase in both as we progress through the week.

I don’t see much in the way of precipitation, but a scattering of showers is possible.

Probability forecasting favors warmer than average conditions into the second week of August. —NOAA
