From chief meteorologist Tony R Petrarca..
As of this writing (11:05pm) temperatures are already in the single digits and still falling. A very cold day ahead for Tuesday. Single digits early morning, only upper 20s by afternoon. Some light snow showers on Wednesday, but its not from a direct storm impact, but rather a shift in wind direction…
Cold east- northeast winds on Wednesday will pick up some Atlantic moisture . The net result will be light “ocean effect” snow showers. Best chance across southeastern Massachusetts…but parts of Rhode Island will see snow showers too. Amounts are will be very minimal, with a coasting to half inch in spots. Low clouds will keep temperatures in the 30s.
