Forecast discussion: After several days of discussing it, the snow finally arrived during the early afternoon. Right now, the National Weather Service has issued two advisories for Rhode Island. North and west of Rhode Island has a Winter Storm Warning in effect until 1 p.m. Sunday afternoon. The rest of the state is under a Winter Weather Advisory, until 7 a.m. Sunday. The low pressure system is currently over Ohio, with a secondary low forming over western South Carolina. The snowfall will begin to come down a little heavier by about 10 p.m., and there may be times where it is falling at about 1-2 inches an hour.
By 2 a.m., we will begin to see warmer air move over the state. The secondary low will become the primary low by this time, as it moves over Long Island, NY and right over central Rhode Island. We will see a mix of freezing rain and rain in the central and southern part of the state. The northern part of the state will see a mix of snow and sleet. By 6 a.m., the whole state will see rain, with showers ending by mid-morning. Also, we will see partial sunshine in the afternoon, making temperatures rise into the lower 40’s. For final snowfall totals, I'm expecting 6-9 inches north and west of Providence. I'm expecting 4-6 inches from Providence to Warwick. From Warwick south, I am only expecting 2-4 inches.
We will see mostly sunny skies on Monday, thanks to high pressure ridging. Any snowfall on the ground will help lower temperatures into the lower teens. By Tuesday, an Alberta Clipper will bring some snow showers by the afternoon. At this time, it is possible to see a few inches by Wednesday morning.
We will see dry weather into Thursday, but we will be seeing another weekend storm, starting by Friday evening. However, the difference with this storm is we will have warmer air coming in from the south. Temperatures will be in the middle 40’s for the day, and staying above freezing during the overnight hours. However, colder air will move in once the cold front passes through during the afternoon. In fact, the precipitation may end as some wet snow.
