Big changes unfold in the next couple of days. A strong storm passes through southern New England on one of the busiest travel days of the year as a double-barrel low pressure area moves north northeast, the first low center passing over western and central New England by the middle of the day Wednesday, and a second low center passing just a little further east later in the day. These combine to bring mild but very wet weather for Wednesday with moderate to heavy rain and even a chance of a few rumbles of thunder. Rain will cause some areas of flooding, especially in poor drainage areas and where leaves block storm drains. A bigger story may be the wind, which will blow from the southeast to south between 25 and 40 MPH with gusts as high as 50 to 60 MPH possible. Wind damage and power outages may result. The peak of both the rain and the wind will be in the window of just before dawn to just after noon on Wednesday before things settle down somewhat. As the storm pulls away, colder air will flow in on the back side of it, and a little leftover moisture means the risk of rain showers going over to snow showers later Wednesday night. There is a chance that a few areas could receive a coating or dusting of snow in the early morning hours of Thanksgiving, but this should not have a significant impact as a dry and cold wind will evaporate most anything that falls by about sunrise.
Thanksgiving Day itself will be a blustery and very cold day, not quite to the level this past Sunday was, but still feeling more like December or January. Although fair weather is expected, it will be quite cold and windy for local travel and high school football games.
High pressure moves more overhead by Black Friday which should be a fair and chilly day. Some clouds may appear in the sky as a very weak disturbance passes north of the region.
The weekend starts bright for the last day of November and turns cloudier for the start of December as high pressure to the north eventually shifts the wind to the east and southeast and allows some moisture to return to the region.
Early next week looks mild and damp and I’ll be watching for a possible ocean or coastal storm around Tuesday.
