Forecast: More Snow Heading Our Way Friday

Update 5 p.m.: 

BOSTON — It appears Boston will be getting a couple more inches of snow than originally predicted. Here's the latest:

Snow begins Boston pre-dawn Friday, ends pre-dawn Saturday. 2 bursts give 1-2" Friday & another 2-4" Friday night. pic.twitter.com/9rYPiOqCe3— Dave Epstein (@growingwisdom) January 29, 2015

Both commutes Friday will have some snow, but I believe evening commute potentially worse. Friday+snow=slow.— Dave Epstein (@growingwisdom) January 29, 2015

Our original post continues:

We have a wonderful winter day on tap, though the morning is quite cold. Skies will also be bright, so don’t forget your sunglasses.

A new storm will move from the Great Lakes eastward Thursday night and then redevelop off the coastline on Friday before heading in the Gulf of Maine Friday night. This storm is a very close call with regard to how much snow we see.

Presently, it looks like northeastern Massachusetts will see the most snow, up to 6 inches before it ends around 1 a.m. Saturday. This 6-inch line could make it further south and into Boston if the storm becomes stronger along the way.

The snow starts early Friday morning, and there will likely be a coating to half an inch of new snow on the ground for the morning commute. This is going to slow down an already slower driving pace, especially on secondary roads.

During the day snow will continue and may even be mixed with a bit of rain at the coastline. For the evening commute, as colder air works back into the storm the snow will become steadier and heavier. The bulk of accumulation will occur at this time.

The storm will end around midnight, and skies will clear during Saturday morning. I expect a blustery and cold day with highs in the upper teens in most areas. Sunday also looks dry and cold.

The potential storm for Monday is still in the cards, but as I mentioned yesterday the track isn’t yet known. This storm could be a complete miss or bring us some accumulating snow, but it’s just too early to say.
