Forecast discussion: After a few light showers passed through eastern Massachusetts early Saturday morning, we had bright sunshine the rest of the day. Temperatures in Boston almost reached 70 degrees. We will see a few clouds during the overnight, so lows will slowly fall into the middle 40’s. A weak cold front over Northern New England will produce the clouds, and the front will move slightly southward on Sunday. Despite the limited sunshine, temperatures will be near 70 degrees once again. However, thanks to a south-southwest wind, the south Cape and Islands will be cooler, as the wind comes off the colder ocean.
The cold front will pass through our area tomorrow night, bringing us mostly cloudy skies. It will remain breezy, and with the cloud cover, temperatures will actually be quite warm, as they only fall into the lower 50’s. We will once again see limited sunshine on Monday, with temperatures reaching 70 degrees in some areas.
The mild weather will come to an end by Monday night. A strong frontal boundary over the Central U.S. will slowly move east, and reach New England by Monday evening. We will see showers at first, but the slow moving front will eventually bring some heavier rainfall by the afternoon. At this time, an inch of rainfall is very possible. Also, behind the cold front will be some very cold air for the middle of April. So, after the front moves offshore, high pressure will bring sunny skies into the weekend. However, temperatures during the day will feel more like this weekend’s low temperatures. We will see a slight warming trend into next weekend, with the chance of some showers ahead of a cold front which would arrive by Saturday afternoon.
