A major winter storm is set to impact the region.
Flurries and light snow will develop across the Cape between 8 and 11PM tonight and quickly become a steady, accumulating snow across the area thereafter. Snow will gradually advance northward from the Cape and into the remainder of Southern New England through the overnight hours, with snow falling across most of the region by Saturday morning.
The brunt of the storm, which will include very heavy snowfall and powerful winds, will come during the day on Saturday. Travel on the Cape, and along much of east coastal Massachusetts, will be nearly impossible through the day with extreme blowing and drifting snow and whiteout conditions anticipated. Folks are advised to stay off the roads unless it is a true emergency. The combination of cold (becoming bitterly cold late in the day) temperatures, falling snow and howling winds will make for life-threatening conditions at times.
Snow – which will fall at rates of up to 2 to 4″ per hour between sunrise and midday – will gradually taper down as we head into Saturday evening and Saturday night. When all is set and down a solid 1 to 2 feet of snow is likely across Cape Cod, the Islands, and throughout much of eastern Massachusetts and Rhode Island. In some areas of eastern Massachusetts, higher totals – closer to 30 inches – are likely…but pinpointing those locations is challenging. Drifts could exceed 6 feet.
During the first half of the storm, temperatures will be relatively mild on the Cape – between 30 and 35F. This will lead to a heavy wet snow for a time, which increases the threat for power outages and tree damage. It’s possible some raindrops or sleet pellets mix in with the snow on the Outer Cape around midday or early afternoon. During the second half of the event, a sharp temperature drop will occur, with readings falling to the 10s and lower 20s.
