Boston SSTs are running 2°F colder than last year for this date and the coldest since 2014, currently at 50°F. It should only get better after the arctic blast starting Wednesday. It won't matter much for these November storms around here, but it bodes well for the usual cliff hangers in December where a degree or two could make the difference, barring any unforeseen extended warmups.
