Weekend Outlook: April 30 – May 3, 2021

We’re stuck in a typical spring weather pattern for New England, which means that it’s not going to be sunny and warm for the most part, and probably won’t be for a while.

Temperatures are in the upper 40s and 50s north of a frontal boundary this afternoon, with 70s and 80s south of it. Image provided by Weathermodels.com

A wavy frontal boundary will be teasing us for the next several days while several waves of low pressure ride along it. South of that boundary, temperatures will be in the 70s and 80s, but north of it, only in the 50s and 60s. Unfortunately, that boundary is going to stay just to the south of our area for the most part. One wave rides along the front tonight, with periods of rain likely. The rain tapers off by Friday morning, and as the low pulls away. we may see some breaks of sunshine develop. As winds shift into the west and northwest behind the system, temperatures will actually warm up a bit, since the winds won’t be off the chilly Atlantic any longer. However, an upper-level low will be moving across the region, and it could help produce a few more showers Friday evening and night. With cooler air moving in, we could even see some wet snowflakes mix in, especially well inland and across some of the hills. High pressure will try to build in on Saturday with some sunshine along with gusty winds and cool temperatures.

On Sunday, that pesky front will try to lift back northward as a warm front. We’ll turn milder, but also have some clouds moving in with a few showers possible, mainly at night. The question becomes, how far northward does that warm front get on Monday? South of the front, temperatures will be well into the 60s and 70s, while north of it, temperatures will only be in the 50s, perhaps upper 40s. Right now, we’re leaning toward the colder side, because that is more typical of early May, but the warm air may settle in south of the Mass Pike. Some showers are also likely during the day, as low pressure slowly approaches from the west.

The models have differing opinions on how far northward the warm air gets on Monday. Images provided by Pivotal Weather.
