Forecast discussion: Providence received a mixed bag of precipitation Monday morning. According to the observations from T.F. Green Airport, we received snowfall from midnight to 4 a.m. From there, it changed over to freezing rain until 8 a.m., followed by a changeover to showers and drizzle for the rest of the day.
We will see some patchy fog until about midnight, when visibility will improve. However, this will not be the end of seeing precipitation. A low pressure system over southwest Georgia at the moment will bring another round of precipitation into Southern New England. This time, the precipitation will be all snow, and we will see it begin by the end of the morning commute on Tuesday. Light to moderate snow will continue into the beginning of the evening commute, before the moisture moves offshore. I feel the south coast will see the highest snowfall totals, but the capital city should see about 1-2 inches by the end of the daytime hours.
From there, a very strong high pressure system from the Rockies will bring drier conditions. However, it will also bring the coldest temperatures of the season. We will only reach the upper 20’s to near freezing up to Saturday. Overnight lows will range from the middle teens to lower 20’s.
As we head into the weekend, the computer models are suggesting another decent low pressure system forming over eastern Texas Saturday. The low, depending on its track, will bring another round of wintry precipitation to the region. There will be more than enough cold air to keep it as snow Saturday afternoon, but warmer air in the lower levels of the atmosphere could create some sleet and freezing rain on Sunday. Colder air behind the low’s center will change the precipitation back to snow showers by late Sunday evening. All precipitation ends by early Monday morning. At this time, the confidence in the forecast for this system is low, as the computer models disagree on the low’s forecast track at this time.
