Forecast discussion: High pressure remaining over the eastern U.S. gave us one more picture perfect day of bright sunshine and warm temperatures on Sunday. It was one of those days you wish you could put into a bottle, and open it up during a cold spell in January. Unfortunately, this summer like weather will be coming to an end. However, we will remember it in the weather record books, as the high of 86 degrees broke the all-time high temperature for September 28.
As we head into this evening, some high level clouds will begin to take over the skies. A cold front over Canada at the moment will slowly make its way down south into New England. At the same time, we will be watching a low pressure system now moving into the Southeastern U.S. These two systems will give us the risk for some isolated to scattered showers after early Tuesday morning.
The models, however, continue to disagree on how far the low will move towards the coastline. On Monday night, the cold front passing through the area may bring a few showers into Tuesday morning. By late Tuesday morning, the low pressure system will move up the east coast, and help to bring scattered showers into the early afternoon on Wednesday. By Wednesday afternoon, a weak high pressure ridge will build over New England, allowing some drier air to move over the area.
We will still have mostly cloudy skies for Wednesday night, with partial sunshine on Thursday. As we head into Friday, we will begin the day with partial sunshine, but by the afternoon a cold front will be bringing some showers and light rain into Rhode Island through Saturday afternoon. A strong high pressure system coming down from Canada will bring bright sunshine back to us next Sunday, but we will see cooler air behind the system.
