Forecast discussion: A strong high pressure system over central Pennsylvania helped to bring picture perfect weather to Providence on Friday. Thanks to northeast winds, we had a cool breeze, and with the dewpoint temperature very comfortable, the humidity remained low.
As we head into Saturday, the daytime will be just fine, although we will begin to feel the humidity increase, especially by the evening. The winds will turn to the southwest, and it will become quite windy by the afternoon. A warm front will be making its way towards New England tomorrow night. We may see an isolated shower or two before sunset. Otherwise, the front will help create scattered showers and thunderstorms around midnight.
As we head into Sunday, we will see some hit and miss showers and thunderstorms. Also, during the mid-morning hours, we may see a lull in the precipitation. A second low pressure system will come in along the front, and help bring another round of showers and thunderstorms by the late afternoon.
The cold front will begin to make its way into the region on Monday, which will continue to bring scattered showers and thunderstorms. The cold front will linger into early Tuesday morning, before it moves offshore. There is the chance we may see some isolated showers into the morning hours, as the American model does not clear us out as quickly as the European model. We will see some partial sunshine during the afternoon.
High pressure will fully take over our weather by Tuesday night, as we will see partly cloudy skies. The sun will return for Wednesday and Thursday, although temperatures will remain in the lower 80’s. A deep long wave trough in the upper levels will remain near the eastern U.S., keeping our temperatures right at seasonable levels.
On Friday, a weak disturbance will form off the Mid-Atlantic coastline. It will remain disorganized, but it will move towards New England. The disturbance will remain offshore, but it will bring the threat of some showers to the area by Friday afternoon. Right now, I feel the chance for showers is slim, as the European model keeps New England completely dry.
