Forecast discussion: I hope everyone enjoyed the milder temperatures Providence has had over the last several days. It helped us get rid of a lot of snowpack. However, it may be just in time to add some more snow to the ground by the middle of the week.
At this time, we will be losing a high pressure ridge that brought bright sunshine and 50 degree weather to Rhode Island. A frontal boundary has passed to our east, and this will allow for colder air from Canada to begin moving into Southern New England. A weak disturbance will pass through later tonight, helping to trigger some precipitation. It will begin as rain showers before mixing and then changing to snow showers. The precipitation will not last long, as it will shut off by the start of the morning commute on Monday. But, a coating to an inch on the ground is expected. So, just take extra time to make it to work or school in the morning.
Winds will also increase Monday afternoon, as the high pressure ridge builds back over the area. It will continue to give us dry, cold weather into Tuesday night. As we move into Wednesday, old man winter is going to return. A low pressure system developing off the coast of North Carolina, coinciding with a weak low over New York will help bring significant snowfall. At this time, it appears the Cape and Islands will see the heaviest snowfall totals, and that could be 3-6 inches at this time. However, if the low continues to move further out to sea, then the snow totals will go down.
All snowfall will end by the early evening, and then temperatures will plummet. Some areas north and west of Providence will see temperatures Wednesday night fall into the single digits, with winds chills at or below zero. Temperatures during the daytime will be well below normal, and we will not even reach freezing. By the weekend, a disturbance passing to our south at the surface will combine with moisture coming off the Great Lakes. On Saturday, with a low moving south of the region, the precipitation will make its way into Southern New England. We will see more light to moderate snow Saturday afternoon, before ending early Sunday morning. With the help of fresh snowfall and Arctic air, temperatures will only reach the upper teens for highs, and lows falling into the middle single digits.
