Forecast discussion: As high pressure off the coast of Nova Scotia loses its grip on Southern New England, we will be seeing a lot of precipitation on Wednesday, although it will be mostly in the form of rain.
Looking at the latest radar image, the precipitation shield is working into southwest Connecticut at this time. Just after midnight, the south coast of Rhode Island should see the first raindrops. The northwestern part of the state will see a mix of snow and sleet to start, before changing to rain around the start of the morning commute. This area may see a coating to an inch of mostly slush before changing to all rain.
Also, there is a Coastal Flood Advisory for the south coast of Rhode Island. Due to the strong easterly winds and high tide around 8:30 a.m., there might be some minor splash over or some water making it onto roads. However, the advisory is only in effect from 11 a.m. to 2 p.m., so this will only be for a short duration. Also, some cities and towns may see some minor street flooding during the morning hours.
Rain will eventually taper to showers by tomorrow night, and some patchy fog will develop. As we head into Thursday, most of the precipitation will move offshore. However some drizzle and an occasional shower remain possible. As we head into tomorrow night, some moisture from lake effect snow will make its way over Southern New England. We may see a coating by Friday morning. By Friday afternoon, the storm system will begin to move out to sea, setting us up for a dry weekend.
This would be the first weekend in three weeks without seeing a low pressure system. We will see partly to mostly sunny skies during the weekend. The computer models suggest that a developing ocean storm will stay far away from Rhode Island, and poses no threat to us for early next week. So, we will start off the new workweek with more clouds than sunshine, before a weak area of low pressure brings us the chance for some rain showers on Tuesday.
