The North Shore and Boston have a chance to see rain after dark, but storms will have weakened at this point.
Temperatures in the mid-80s and humid conditions will fuel an afternoon front, packing the ingredients for summer storms west and north of Boston.
“Wind and flooding are my greatest concerns, and you heard me mention tornado, and it is a day where although it is a low threat, it’s very much there,” said Antico during his Saturday morning forecast.
Sunday is shaping up to be drab, with plenty of moisture in the forecast.
Because it will be cooler and less humid, severe weather isn’t a concern, but southern New England is in for cloudy skies and on-and-off showers.
