Projections for Friday’s storm are now suggesting a historic event that could dump as much as two feet of snow on Narragansett and South Kingstown by the end of it all on Saturday night.

The National Weather Service officially upgraded the weather advisory from a winter storm watch to a blizzard watch on Wednesday night. For their latest advisory, which was released at 4:25 a.m. Thursday, click here.

Except for very tiny slivers of land by the coast and Cape Cod, all of Rhode Island and Massachusetts is now projected to get between 18 and 24 inches of snow.

As far as the storm’s timetable, according to the NWS, light snow will begin on Friday morning. This will give way to rain as morning segues to afternoon, but from Friday night to Saturday afternoon, a long stretch of heavy, wet snow is expected.

In addition, sustained winds of 40 to 50 miles per hour are projected, with gusts up to 75 miles per hour. Whiteout conditions are possible, with visibility falling to a quarter of a mile at times.

Although no school districts have officially cancelled for Friday as of Thursday morning, many are expected to following classes on Thursday. Some are already taking preemptive measures – For example, Chariho has rescheduled Friday sporting events for either today or next week.
