Tuesday Insights: Leftover Tropical Moisture to Graze Part of New England

We’re heading into a more fall-like pattern, but the dry stretch we’ve been experiencing isn’t going anywhere fast. Over the past 30 days, most areas across New England have seen a rainfall deficit of 1-3 inches, with dry conditions particularly notable in Southern Maine, Southeast New Hampshire, and Northern Massachusetts where “abnormally dry” conditions per the drought monitor are in place and are likely to be expanded during their Thursday morning map update.

The closest chance for some wet weather will be Wednesday evening into Thursday morning, mainly along the South Coast, Cape Cod, and possibly as far north as Boston. Any rain that falls won’t be significant, with most areas likely receiving less than half an inch. Some locally higher totals on Cape Cod could result if the steadier rain and downpours shift over that area. By Friday, some drizzle or light showers may persist, particularly near the coast, but the general outlook remains dry.

The upcoming weekend looks fantastic for outdoor plans! A new areas of high pressure will nudge its way in, bringing cooler fall temperatures, with highs in the 60s to low 70s and just a stray shower possible. Plus, the fall equinox kicks off Sunday morning, so it’s time to officially say goodbye to summer.

Coastal communities should prepare for rougher seas as low pressure offshore brings waves up to 5-8 feet Thursday into Friday, perhaps lingering into the weekend. We’ll also see gusty winds from the northeast in combination with astronomical high tides resulting in minor coastal flooding possible along the South Coast during periods of high tide.
