Snow will overspread much of Massachusetts, Rhode Island and Connecticut between 11 AM and 2 PM and will likely become moderate to perhaps briefly heavy for an hour or two before mixing with sleet and then changing over to rain. Snow accumulations will range from a coating to two inches, with a low probability of a few locations picking up near 3 inches. However with temperatures at or slightly above freezing during this time, most snow accumulations will be confined to non paved surfaces. The exception will be across the higher terrain where colder temperatures will result in a minor slushy accumulation on area roadways. Nonetheless moderate snow will result in poor visibility and impact travel. However by 4 PM or so much of the snow will have changed over to all rain, providing little if any impact to the late day commute.
