Weekend Outlook: May 15-18, 2026

The warmer weather that you’ve been waiting for is finally arriving.

Showers taper off this evening, but don’t end until Friday afternoon. Loop provided by WeatherBell.

Low pressure passing south of New England brings us some much-needed rain this evening, tapering off to showers overnight as the low gets stuck under an upper-level low and only slowly pulls away. Friday will feature lots of clouds, cool temperatures, and some additional showers, especially during the morning, before the low pulls far enough away to lose its influence on our weather. High pressure then builds in, with skies clearing out Friday night, setting the stage for a fantastic weekend weatherwise. Sunshine is likely for much of Saturday, with some clouds around during the afternoon as the upper-level low remains nearby, but we should see temperatures getting well into the 70s away from the South Coast thanks to gusty southwest winds. Sunday looks even better, for the most part. We’ll have partly to mostly sunny skies with temperatures topping 80 inland, 70s or 60s along the coast thanks to a seabreeze, as winds will be lighter. However, we’ll be watching a backdoor cold front trying to move down the coast. How far south it gets and when it does so are a bit of a question mark. This could allow much cooler air to move into at least coastal areas late Sunday into early Monday, but it does look like it should start to lift back northward on Monday, allowing areas that turned cooler to warm back up, while inland areas may stay very warm. Although it isn’t technically part of this outlook, we figured we’d point out the fact that Tuesday as the potential to be a very warm to hot day, with temperatures possibly topping 90 inland.
