Get ready for Nor’easter Round Two.

Another storm is coming to Boston on Wednesday, less than a week after the nor’easter that brought plenty of rain, wind, flooding, and power outages.

First, let me say what the storm is not going to be. This week’s nor’easter will not bring about the coastal flooding we saw last week. This storm will not be as intense, and the tides are going to be quite a bit lower than they were on Friday and Saturday, which saw the highest tides of the month. The storm will also not bring about the extreme winds we saw Friday. Gusts may reach 50 miles per hour along the coast, but we’re not going to see hurricane-force winds.


What we will see is a rain-snow line close to the city of Boston and the potential for up to a foot of snow in those areas that stay all snow. If the storm moves slowly enough and the cold air sticks around long enough, some places could even exceed a foot of snow.

Temperatures are going to be marginal for snow, which means what does fall will be heavy and wet. My early concern is that this snow will cause power outages inland just as power is being restored along the coast. This has the potential to put a lot of stress on power companies and their workers.

The snow should arrive sometime Wednesday, with the heaviest snow overnight on Wednesday, causing issues with the Wednesday evening and Thursday morning commutes. The storm will wind down quite early on Thursday.

The greatest chance for an all-snow event is going to be west of Interstate 495, and for an all-rain event over Cape Cod. This means the Boston area ends up in the middle, as we often are, leaving us with possibilities ranging from a moderate to major snowstorm to one that is mostly rain.

Forecasters will have a better idea of the rain-snow situation on Tuesday, but you should stay tuned to the latest forecasts. If you can move some things around in your travel plans, try to stay away from Wednesday afternoon through the first part of Thursday to be on the safe side.
