Weekend storm

WEATHER ALERT

The storm we have been talking about for several days is here. This unusually cold late-May storm will bring periods of heavy rain, damaging wind gusts, rough seas, and even some snow across the higher elevations of northern New England.

RAIN: Rain will overspread southern New England overnight and continue through much of Saturday. Total rainfall amounts of 0.50″ to over 1″ are likely, with locally higher amounts possible. The steadiest and heaviest rain is expected during the morning and midday hours before gradually tapering during the afternoon. While the rain becomes more scattered later in the day, a few spot showers may linger into Saturday evening.

WIND: Another concern will be the wind. A Wind Advisory is in effect from 8 AM to 8 PM Saturday with a High Wind Warning for the Cape and Nantucket. Wind gusts of 45 to 65 mph are possible, strongest along the coast and over the Islands. These winds could lead to isolated tree damage and scattered power outages.

COAST: Along the coastline, marine conditions will become dangerous. A Storm Warning remains in effect for the coastal waters with very rough seas and hazardous conditions for mariners.

SNOW: One of the more remarkable aspects of this storm is just how cold it is for late May. Snow is expected across the higher elevations of northern New England (mainly Mt. Washington), and while a wet flake or two can’t be completely ruled out in the Worcester Hills, no accumulation is expected locally. It does highlight the unusually chilly air mass moving into the region.

CHILL: Temperatures on Saturday will hover near 50 degrees for much of the day, but strong winds will make it feel significantly colder. Wind chills will remain in the 30s and 40s, creating a raw feel despite it being the end of May.

Conditions gradually improve Saturday night as winds slowly diminish and showers come to an end.

NEXT WEEK

Sunday will be the pick of the weekend. We’ll start with a mix of sun and clouds and temperatures will rebound nicely, reaching near 70 degrees during the afternoon. Clouds will increase later in the day, and a few showers will develop after sunset.

The weather remains unsettled to start the week as an upper-level low swings through New England. Monday will feature periods of rain along with the potential for a few thunderstorms. Showers remain possible on Tuesday as well, with temperatures holding in the 60s.

By the second half of the week, we begin to turn the corner. Sunshine returns Wednesday through Friday, and temperatures will steadily warm. By Friday, highs are expected to surge into the 80s, providing a much more summer-like finish to the week after our chilly and stormy weekend.
