Forecast discussion: A warm front passed through Rhode Island Thursday afternoon, helping to lower the cloud bank and produce some dense fog for the evening commute. The fog will remain thick through the evening, as a Dense Fog Advisory remains in effect for all of Rhode Island until 3 a.m.
We are awaiting a cold front to push through Friday morning. We will see some showers develop during the overnight hours, as the front inches closer to Southern New England. Heavier precipitation will arrive during the late morning and afternoon hours, and will continue into the evening. By Friday night, colder air will help change the precipitation to a frozen variety. At this time, it appears to be some wet snow showers, although a little sleet may mix in from time to time. The frozen precipitation changes back to plain rain by the middle of Saturday morning, before all precipitation ends around noon. We should see some sunshine before sunset, as skies continue to clear going into Saturday evening.
We will see sunshine during the daytime hours on Sunday, and it will be colder. Clouds will be increasing throughout the evening. This will be due to a developing area of low pressure around the Tennessee River Valley. The system will push high pressure into the Atlantic, and bring another round of winter precipitation into the region. This time, it will begin as some wet snow showers, before changing to a mix of sleet and freezing rain. This will continue into the morning commute on Monday morning, so you may want to take some extra time to arrive at work or school. Also, please take extreme caution while driving. Before lunchtime, precipitation should begin to change over to all rain. The showers will end by Monday evening.
For the rest of the forecast period, we will see partly to mostly sunny skies and cold temperatures. High pressure will influence our weather pattern, with daytime high temperatures only near freezing, with low temperatures in the upper teens to lower 20’s.
