Our nor’easter continues to bring gusty wind and waves of rain across southern New England tonight. More heavy rain and even higher wind gusts along with increased wave heights are forecast for Thursday into Friday as the storm stalls south. We won’t see an end to the raw conditions until a cold front sweeps the storm away by the end of the weekend.

Timing, Rain:

Showers have been steady across Connecticut, Rhode Island and Massachusetts all day. There will be a few breaks in the heavy rainfall, but more waves of rain will move in tonight and last through Saturday morning.

The heaviest rainfall totals will be across southeastern Massachusetts. By Saturday, they could see 3-6” of rainfall which may lead to some street flooding. 1-3” of rain is likely across Rhode Island and central Massachusetts to Boston. Less than an inch of rain is expected in western Massachusetts, central Connecticut and southern Vermont and New Hampshire.

Northern New England will miss out on all this heavy rainfall. They will continue to see cool temperatures and breezy weather through the end of the week. Falling leaves will add to the slick road conditions and may also clog the storm drains.

Wind:

The wind gusts will increase gradually tonight and will stay strong through Friday morning. Peak winds between 30 and 40 mph will be likely from Boston to Worcester, with higher and more damaging wind gusts across the coastline. The south shore, Cape Cod and the islands will see 50-60 mph gusts. This will lead to some power outages and damage may be more widespread with the leaves still on the trees and weighing them down.

Coastal Flooding:

We have four tide cycles where there is a chance for splashover and possible minor flooding in low-lying communities. Our tides are astronomically low, but the wave heights offshore will be 10-20 feet from Thursday morning through Friday night. As we continue to see a northeast flow, there will also be beach erosion on northeastern facing beaches.

10-Day Outlook:

A cold front heads through Saturday into Sunday, sweeping out the nor’easter. Lingering showers will taper Saturday, and we clear out Sunday with sunshine and temps in the low 60s. We keep a break in the rain through Monday. Showers return for mid-week next week as temperatures stay with the autumn season, highs in the low 60s to 50s north.
