The calendar says it’s autumn, but it doesn’t feel like it when we’re talking about high temperatures in the 80s in Boston. But all good things must come to an end. We’re tracking big changes in your First Alert Forecast this week.

Enjoy the 80s and sunshine today! Hey, if you have a chance tonight, check out the full Harvest Supermoon! It’s the first supermoon of 2025, appearing larger than usual. Skies will be mostly clear tonight as the moon shines very bright in the sky. The moon will be in its full phase around 11:48 p.m. Monday. But even before that, around sunset, look east as the moon rises over the horizon. It should look spectacular, with even some hints of orange and yellow tints to the moon. Check it out!

Tomorrow, many areas will be in the 80s again under mostly sunny to partly cloudy skies. A cold front will move into the area on Wednesday, giving way to rain through much of the morning and into the mid-afternoon. Some pockets of heavy rain are possible. An isolated storm could develop, but no severe weather is expected. High temperatures on Wednesday will be in the mid 60s.
When will it rain on Wednesday?


How much will it rain?

Once the front is to our east by Thursday, our high temperatures will sink into the upper 50s. Morning temperatures by Friday will dip into the 30s! Start preparing today for the chill by the end of the week.
