Forecast discussion: After a cold front passed through Rhode Island earlier Wednesday afternoon, high pressure ridging began to build over the area. This caused winds to increase during the afternoon. Winds will diminish this evening, as clear skies and diminished winds will help bring temperatures down to near freezing. Even with bright sunshine on Thursday, increased winds will keep temperatures in the middle 50’s inland, and near 50 degrees along the south coast.
As we head into Thursday night, clouds will be increasing as a frontal boundary inches closer to the Northeast U.S. A weak cold front will bring some possible showers early Friday morning. We will see scattered showers through the day, with showers coming to an end by late Friday night. A new high pressure system will bring sunny skies for Saturday. The high will influence our weather into Sunday, although another weak front will bring some isolated showers by Sunday night.
The showers will end by Monday morning, although we will see limited sunshine. A strong high pressure ridge offshore will keep a very strong cold front to our west through the day. However, the ridge will break down by Tuesday, allowing the front to move eastward. We will see showers at first during the early morning, and one model continues to show very heavy rainfall by Tuesday afternoon. Because the front will be moving very slowly, we could see another round of significant rainfall. Eventually, the front will move offshore, as a strong high pressure system brings down some very cold air for this time of the year into New England. We will see sunny conditions by the midday on Wednesday, but temperatures will struggle to reach 50 degrees in some areas.
