A light wintry mix will make for a wet and sloppy Thursday as many of us head out back to work, malls or returning home from our Christmas destination. The precipitation will be a nuisance only as very little snow accumulation is expected, mainly outside of the Route 128/95 corridor, where one half to one inch snow could accumulate. Its possible that secondary roads become slippery for a time. Along the coastal plain the light snow changes to mostly rain keeping any snowfall accumulation unlikely.
The low pressure system responsible for Thursday’s inclement weather will track quickly into the Canadian Maritimes Thursday night and Friday. Skies improve rapidly Thursday night and a pretty nice Friday will unfold as high pressure returns. We can look forward to a nice start to the upcoming weekend, the last of 2013, as dry and seasonably cold weather should be with us Saturday as well.
Low pressure will emerge out of the Gulf of Mexico and move up the coast. It is still somewhat uncertain as to the exact track of this storm, however early thoughts are that it moves well offshore, southeast of Nantucket Island Sunday night. This would bring a glancing blow to the local area, with southeast Massachusetts and the Cape and islands seeing more of an impact from the ocean storm. If the track moves further toward the coast then we can expect more of an impact. Further offshore, then a complete miss.
If you are going to the New England Patriots game be prepared for the possibility of wet weather as the system could impact the area during game time.
