Late-Week Nor’easter Could Bring Rain and 40-MPH Coastal Gusts to Boston, but Track Remains Uncertain

A nor’easter could bring strong wind and plenty of rain to Greater Boston from late Thursday into early Saturday, NBC10 Boston forecast Monday, Nov. 9. The National Weather Service office in Norton said the same day that a lot of uncertainty remained about the storm’s track and its effects on southern New England.

What the forecasts say

NBC10 Boston said the storm promised strong wind and plenty of rain, and possibly the season’s first snowflakes in some places. The station said wind gusts could top 40 mph at times, mainly along the coast.

The station said it expected the storm to begin late Thursday and end by early Saturday or very late Friday night. Along the coast, NBC10 said it was more confident the precipitation would stay rain for the whole storm.

Snow could mix in across northern New England on Friday, NBC10 said. It could reach the higher terrain of southern New England on Friday night or very early Saturday, according to the station. NBC10 said it was too early to estimate snowfall amounts.

Where the forecasts differ

The weather service’s forecast discussion, issued at 2:05 a.m. Monday, described computer models that disagreed on the storm’s path. It said only that unsettled weather “may return late this week.”

The American GFS guidance favored a warmer and wetter storm tracking more directly over the region, the discussion said. That scenario would keep precipitation mostly rain. Wet snow would be possible on the eastern slopes of the Berkshires and the higher elevations of the Worcester Hills.

The European and Canadian models brought colder air in earlier, the weather service said. Those models also tracked the center of the storm farther from the region, which would keep it drier.

NBC10 said the exact track and intensity likely would not be settled until Tuesday or Wednesday. The weather service said more should become clear as this week’s earlier weather systems develop.

The days before the storm

Highs were forecast in the mid-to-upper 50s Monday under clouds, with a passing shower threat, NBC10 said. The weather service said showers were most likely from late morning into the afternoon, especially in the higher terrain of western Massachusetts.

Wednesday, Veterans Day, looked like the sunniest day of the week, according to NBC10. The weather service forecast highs in the 50s and lows in the 30s and 40s through midweek.

On the water, a Small Craft Advisory ran until 7 a.m. Wednesday for parts of the coastal waters, the weather service said. Its marine outlook called for rain likely Thursday night and Friday, with gusts up to 35 knots and rough seas up to 11 feet on Friday.

Sewage advisory expired Monday

A separate City of Boston public health advisory on a combined sewer overflow expired early Monday. A Massachusetts Water Resources Authority outfall at the Prison Point facility had a treated discharge or overflow from 8:20 p.m. Nov. 6 to 12:07 a.m. Nov. 7, the city said.

The event affected the Inner Harbor, and the advisory ended at 12:07 a.m. Monday, the city said. Combined sewer overflows occur when a large storm overwhelms the sewer system, according to the city. Boston advises the public to avoid contact with affected water bodies for at least 48 hours after a sewage discharge and during and after rainstorms.
