Forecast discussion: Despite high pressure over western Pennsylvania, we lost the sunshine in Providence by Saturday afternoon. This was mostly due to a weak disturbance south and east of Cape Cod and the Islands. Snow showers remained offshore, but the moisture associated with the disturbance brought high and then middle level clouds over the region.
The clouds will remain over us for Saturday evening, as the high begins to break and down and dissipate. A weak area of low pressure moving into the Great Lakes will gain some strength and form a weak low pressure center over the Mid-Atlantic Sunday afternoon. The weak area will gain some moisture off the Great Lakes, and help to create some snow showers by late Sunday afternoon. We will see scattered to constant snow showers through Sunday night, but end by the middle of Monday morning. Some areas may see just a coating on the ground. However, north and west of Providence may see an occasional snow band, allowing for up to 2 inches to fall. I would not be surprised if there were isolated areas seeing 3 inches of snow.
By Monday evening, a strong high pressure system coming down into the Rockies will move over the Central U.S. We will see sunny conditions, but once again Arctic air will give us well below normal temperatures. By Tuesday night, temperature will fall below double digits. However, by Wednesday night, some high level clouds will help keep temperatures in the upper teens.
As we look to the end of the week, the computer models continue to go back and forth with a possible coastal storm. However, it appears that the timing has changed. Now, it appears many computer models keep the low from moving up the east coast until early Friday morning. So, we will not see any precipitation until early Friday morning. At this time, the precipitation will be a mix of sleet and snow going into Friday morning, before temperatures are so warm, the precipitation changes over to rain. We will also see some melting, as temperatures remain above freezing for Thursday and Friday. By Friday night, the precipitation will change back to snow showers, before the precipitation shield moves into the Atlantic early Saturday morning. A weak area of high pressure will give us limited sunshine by next Saturday afternoon. But, temperatures will be slightly above normal for this time of the year.
