Breaking Down Unsettled Weather Coming to New England

Unsettled weather is returning to New England for the next several days thanks to a very slow-moving frontal boundary. This boundary will drop into New England Friday afternoon and hang around through the weekend, leading to a mostly cloudy and unsettled weekend for the region. Despite this, the weekend will not be washed out. Here's a look at each disturbance and what they will likely bring to New England.




FRIDAY AFTERNOON-SATURDAY MORNING | IMPACT: LOW


A quick-moving, weak area of low pressure will bring light showers across the entire region during this time. The showers will move across New England from west to east, likely starting around sunset and continuing through sunrise. This is a fast mover and will likely be gone for all but eastern Maine by early Saturday morning.


Expected weather overnight Friday into Saturday morning:


This will be a mild system that will bring rain showers to pretty much everyone in the region. Some light snow showers will be possible across northern areas toward the Canadian border and Green Mountains, but most areas will likely have trouble accumulating anything. Areas in Vermont above 1,500 feet would stand the best chance to get some snow on the ground by Saturday morning. For everyone else, rainfall will generally be light and will add up to a quarter of an inch or less.



SATURDAY AFTERNOON & NIGHT | IMPACT: LOW


Another quick disturbance will skirt through Saturday afternoon. At this point, the frontal boundary will likely be draped right across New England. This will lead to more showers in northern New England during this time. Showers, both snow and rain, will begin to pop up across New England Saturday afternoon.


Expected weather Saturday afternoon:


These showers will likely be most numerous near the Canadian border and gradually diminish in coverage as you work south. Central and southern New England will likely see a mainly dry, but cloudy day on Saturday with some on and off drizzle possible. These scattered showers will likely continue through the night and into the morning.



SUNDAY | IMPACT: LOW


Models begin to diverge more heading into Sunday, leading to more uncertainty. Sunday will likely see more widespread showers across all of New England as the next disturbance moves through the area. By Sunday, the frontal boundary will likely be south of New England, leading the disturbance to the south. This will again be mainly rain showers with light snow snowers across northern Maine. Areas of northern Maine could see a couple inches of snow throughout the day.


Expected weather Sunday around midday:


Sunday afternoon and evening will likely be determined by the timing of a more organized system approaching the region. The summary is to expect cloudy and damp weather through Sunday, but the entire day likely won't be washed out.



SUNDAY NIGHT-MONDAY | IMPACT: MODERATE?


With models beginning to split on Sunday, there remain questions about the impact of the more organized system likely coming late in the weekend to early next week, which is why we're putting the impact on moderate for now. Right now, major models are favoring this system coming through Sunday night into Monday before exiting Monday night.


This storm will likely feature a rain/snow line with southern New England seeing mainly rain and the higher elevations of northern New England and northern Maine seeing snow. Exactly where the rain/snow line sets up in between remains to be seen. This will be determined by the storm's strength and ultimate track. Some models are giving a stronger and snowier storm while others show a weaker and rainier storm.


What the Euro, GFS and CMC are showing for Sunday night/Monday:


This discrepancy is mainly due to the fact that the pieces of this storm are currently over the Pacific Ocean. Models can have some trouble figuring out exactly what a storm will do until it enters the United States, where the pieces come together in the upper winds over land.
