The first four days of March are averaging 8-14° colder than normal in Southern New England. The temperature started in the single digits in most spots early Tuesday before bouncing back into the mid to upper 20s in the afternoon. A few places, primarily in Eastern Massachusetts, reached 30. There was plenty of sunshine and a relatively light breeze.
Clouds will increase Tuesday night as the wind swings around to the north-northeast by dawn. The breeze will be barely noticeable at less than 5 mph. Lows will be in the mid teens in the countryside, and near 20 in the cities and near the coast.
Wednesday looks mostly cloudy with the chance of passing snow showers or flurries. A coating is possible on the grass. Roads will not become snow-covered with light snow likely and the temperature in the low 30s combined with a high early March sun angle to melt any snow on pavement. The snow showers will not be widespread, and the threat of light snow showers continues into Wednesday evening. A coating is possible after dark as the temperature falls through the 20s.
Thursday looks mostly sunny and cold, with highs again struggling to reach 30° after morning lows in the teens. The weather looks quiet and gradually milder from Friday through the weekend. Friday will be mostly sunny with highs in the mid 30s – still cool for this time of the year. Saturday will be partly cloudy with highs in the mid to upper 40s as the wind shifts to the west ahead of a cold front. The front will move through Saturday night or early Sunday with the chance of snow showers or flurries. Sunday looks dry and seasonable, with highs in the low 40s.
