Forecast discussion: A strong high pressure system centered over Indiana at the moment is bringing dry weather for the entire east coast. This included, Providence, of course, as we had beautiful but cold sunshine on Friday. We will see the sun mostly in the morning, as some mid and high level clouds begin to move over the region by Saturday afternoon.
As we close out the weekend a weak area of low pressure, known as a trough, will come out of the Great Lakes. It will meet up with some upper level dynamics, to help create a low pressure center in the Mid-Atlantic Sunday afternoon. We will see some snow showers develop in the area by Sunday afternoon. However, this is going to be a pretty weak system. We may see a coating of snow by Sunday evening. Light snow showers will continue through the evening, and end by Monday afternoon. The most snowfall I can see will be about 2 inches, mostly north and west of the capital city.
By Monday evening, Arctic air will reign back down into New England from Canada. Temperatures will be bitterly cold Tuesday night, with lows falling into the middle single digits. With cloudy skies Wednesday night, temperatures will rebound into the middle to upper teens. I am still watching a potential coastal storm for Thursday. However, at this time, it appears we will stay on the warmer side of the low. So, the precipitation will start off as snow showers, before changing or mixing with sleet and rain. The precipitation will change back to snow showers Thursday night, before ending Friday morning. At this time, the computer models are either keeping the low’s center near the coastline, or completely taking it out to sea. For now, my confidence in Thursday’s forecast is very low.
