8:25PM
A stormy night is underway, but the rain part of it will not last long. The heaviest is moving into the Boston area from the southwest as of 8PM and will be gone in about 4 hours. The positives about this are that it is quick-moving, the unfrozen ground allows absorption of the rain, and the lack of a frozen snowpack means less threat of flooding.
The main story with this system will be the wind. Strong south to southwest winds may occur with the heaviest rain especially south of the Mass Pike. As the storm passes north of the area and moves away Wednesday, strong northwest winds are expected on the back side. Some minor wind damage may occur, and power outages, though not widespread, are not out of the question. Dry weather will be back for Wednesday, with any snow showers hanging out in the Mountains far west and north of Boston as colder air moves in. Temperatures will fall during the day.
Expected a cold and dry Thursday as high pressure dominates.
By Friday, warmer air will try to move back in, and riding up over the cold air it will generate some snow and rain showers in the region. By late in the day and at night, a stronger impulse is expected to cross the region and may produce a general period of mixed precipitation to snow, with just enough cold air in place. By later Saturday, New Year’s Eve, mostly dry weather is expected but a gusty breeze and chilly air is likely. It will not be frigid, however, as some New Year’s Eves have been around these parts.
A milder day is expected for the first day of 2012.
Longer range models are divergent in their forecasts for what goes on during the first week of 2012, with one showing weak weather systems and no major storms, while the other shows a major storm threat for the East Coast. In the interest of the New Year’s weekend upcoming, and many other things going on during the next few days for holiday week traveling, I’m going to just leave next week alone for now and look at it later.
