Weekly Outlook: October 19-25, 2026

While the forecast for the upcoming week looks complex, it’s actually rather simple.

Low pressure will mill around south of New England for much of the week. Loop provided by Tropical Tidbits.

A large area of high pressure will provide us with more sunshine and slightly milder temperatures today, but we’re going to be watching a developing low pressure area off the Mid-Atlantic coastline. The system will meander around for a few days, blocked by the large high pressure to the north. The gradient between the high to the north and low to the south will result in breezy to occasionally windy conditions, especially along the coast from Tuesday into at least Thursday if not Friday. We’ll see some clouds start to move in ahead of the low pressure system later today, but the big question is whether any rain gets this far north. While many models keep the entire region dry, several bring a period of some showers at least to parts of Cape Cod and the South Coast towards Wednesday, some bring it even farther inland. The system starts to pull away on Friday, then high pressure builds back in for the weekend.

Will the system spread some rain in late Wednesday across Cape Cod? Images provided by Pivotal Weather.
