We haven’t had a completely dry weekend since September, and this weekend is no different.

But there’s a silver lining: The rain begins later Friday, and it will be over by the time most of us wake up Saturday morning. That means this weekend should end up dry during the daylight hours.

Here’s more detail on the incoming rain as well as your complete weekend weather forecast.

The rain begins Friday evening.

Friday features a little bit of sunshine early, but the clouds will thicken up during the day. I expect showers to start approaching western sections of the region after 3 p.m., but the heaviest rain will definitely hold off until after the evening commute is complete.


The rain will continue overnight into Saturday. If possible, clear leaves from gutters and storm drains —  the rain will be quite heavy.

High temperatures will reach near 50 degrees.

On Saturday, the rain shuts off very early, but be aware that heavy rain overnight may cause some small streams and rivers to flood.

High temperatures will brush the lower 50s around Boston and be slightly warmer south of the city.

Fields will still be quite wet, so if you have soccer, football, or other activities, including raking leaves, keep in mind that the ground will not dry out for several hours. Winds will pick up and temperatures will actually fall throughout the afternoon. Saturday night will be chilly.

Sunday will be unseasonably chilly.

That leads us into Sunday when temperatures stay in the low to mid 40s. There will be plenty of sunshine, though, making it a good day to work outside as Saturday’s dry weather should’ve made some of those leaves more manageable.

Looking ahead into next week, another storm system moves in Tuesday with more periods of heavy rain and gusty winds. It’ll then turn very chilly for the second half of next week.
