BOSTON (CBS) – It was a great start to the last weekend in March. In bright sunshine, the heights rose into the 1960s, with 1950s in Boston and on the Cape and on the islands thanks to a developing sea breeze.
Unfortunately, the sunshine in the rear-view mirror is a low-pressure system and an approaching cold front will bring scattered rain and wind for Sunday.
Sunday morning starts dry with increasing clouds and temperatures in the low 40s. If you have to walk the dog or run errands, early morning is your best bet. In the morning, rain develops sporadically, which spreads around noon.
Expect rains through the afternoon as temperatures climb into the upper 50s by the evening. Wind gusts of 40 to 50 mph will likely develop over southeast New England by late Sunday afternoon. Some embedded thunderstorms may be possible in the evening, the main threats being lightning and noxious gusts of wind.
The showers leave the region between 10 p.m. and 10 p.m. from west to east. until 2 a.m., last over the cape and the islands.
The favorable amounts of precipitation are between 0.50 and 1.25 inches, with occasional higher amounts possible when thunderstorms occur.
Wind will likely be the main threat to this system. As the afternoon unfolds, a powerful low-level jet will attempt to create some gusty conditions along the southeast coast, cape, and islands. Wind may blow up to 45 miles an hour.
While the rain will come to an end, our attention is shifting to the strong to potentially noxious wind threat from Sunday evening to Monday afternoon. In the wake of the cold front passage, westerly winds can blow 40 to 55 miles per hour, with the strongest gusts blowing Monday morning into the early afternoon.
The east side of the Berkshires, the higher elevations of Worcester County, and the Outer Cape and Cape Ann can experience some of the strongest gusts of wind.
Minor tree and power line damage is possible, leading to isolated to scattered power outages. The winds will ease a bit in the afternoon, but will still be 25 to 35 mph.
Monday will be bright but cooler. The highs only reach the top 40’s and feel more like the 30’s all day due to the wind.
Temperatures are warming to end March with highs in the 60s on both Tuesday and Wednesday. The sunshine will fade behind the clouds on late Wednesday as our next system approaches and the rain is expected to start in April.
We will continue to update the timing and rainfall amounts as new information comes in. So stay up to date!
