The wider storm
A robust Pacific shortwave moved east from the Great Lakes with attendant
primary low tracking well to the north on the 18th bringing accumulating snow Saturday afternoon and night. A secondary low developed in the Gulf of Maine late Sat night which was too far north to stop low level warming from advancing northward across southern New England Saturday night which changed snow to rain/wintry mix before ending. The precipitation ended by early Sunday as the storm moved away, followed by drier and colder weather.
