The slow transition from abnormally warm to seasonable cold continues. Another wet day will be the result today. There may not be much rain falling at AM commute time, but during the course of the day, it will get wetter, and the PM commute will be a soaker. Some heavy rain will occur during the evening hours. As the wave of low pressure responsible for this races by in the early hours of Thursday, colder air will be coming in, resulting in some snow in higher elevations and a mix with or flip to sleet then snow elsewhere including closer to Boston. This will not be a significant snow event for most areas, with only mountain areas well west and north of Boston seeing any appreciable amounts. The Boston area will see nothing more than a slushy coating of snow early Thursday, with up to 1 inch in the 495 belt.
The express-train storm will be gone by mid morning Thursday with sun returning at that time, along with a gusty breeze and chilly air. A disturbance approaching the region Friday may produce a few clouds but most of them will move in at night and early Saturday, when there may be some snow showers or even a period of snow, before the system moves away. This does not look like an important system.
Dry and seasonably chilly weather will dominate the region on Sunday followed by some moderation in temperature early next week.
