A Memo from MEMA:
Severe Weather Potential for Thursday afternoon and evening...
There is some potential for severe thunderstorms late this afternoon or evening.
An approaching cold front will likely trigger widespread thunderstorms Thursday afternoon and evening from generally northwest to southeast.
Most of central and southern New England are at risk for some of these thunderstorms to become severe with damaging winds, large hail, and excessively heavy rain.
This is still too far away to know precisely how the event will unfold. It does seem likely, however, that there will be at least a few severe thunderstorms as a result of a very unstable air mass, approaching cold front, and moderately strong winds aloft.
There is some suggestion that the storms may form in one or more squall lines but it's too early to be sure. There will be a greater chance of strong or severe thunderstorms making it to the coast Thursday evening (as compared to this evening).
Please monitor weather.gov/boston for any later statements, watches, or warnings. If a Severe Thunderstorm Watch should be issued either later today, tonight, or Thursday, we suggest that you have a NOAA Weather Radio nearby in the event of any warnings being issued.
