Forecast discussion: A low pressure system well into the western Atlantic helped keep cloudy conditions over Providence today, but it was warmer. But, we will see colder air once again move over New England within 24 hours, and remain over us into early Saturday morning. Meanwhile, we will see two more chance for snowfall, although the weekend storm may see a wintry mix or even rain mix in with the snowfall.
For this evening, a series of low pressure systems will be passing into New England over the next 18 hours. The lows will help trigger some snow showers, which have already moved north of Boston, according to the latest radar image. We will see light snow showers through the evening, with light snow after a cold front passes to our south. We may see another 2 inches in total of snowfall before the light snow ends Thursday night. As we move into Thursday night, a new blast of cold air coming from the north will move over New England. Low temperatures will fall to near or below zero Thursday night. With breezy conditions, a Wind Chill Advisory may be needed.
We will enter Friday with a high pressure system over the Mid-Atlantic, giving us bright sunshine. But, with the Arctic air remaining over us, high temperatures for the day will only reach the middle teens. We will see partly cloudy skies Friday night, and temperatures will once again fall to zero. However, winds will be lighter, so I am not expecting a Wind Chill Advisory for Friday evening.
As we head into the weekend, the start of Saturday will be dry, as we begin to lose the influence of the high. Two different low pressure systems will bring moisture towards the east coast early Saturday afternoon, but the one from Arkansas will become the primary low. The precipitation will start off as snow just before midnight. But, as we move into the mid-morning on Sunday, temperatures will actually rise above freezing. So, I am expecting a transition of snow to either a mix of freezing rain and rain, or, for the first time since December, just plain rain. Although this will help us not add more snow to our totals, it will help weigh down a very thick snowpack. This will definitely create more stress on roofs that still have too much snow on them now. In fact, a custodian working at a Cumberland school was hurt today while helping to shovel snow off a roof. Unfortunately, she went through an unseen skylight. For the story, click here.
As we move into Sunday night, the low will pass off to our north and east, allowing the cold front to push through Southern New England. So, the precipitation will eventually change back to snow showers before the precipitation ends around midnight. High pressure in the central U.S. will give us mostly sunny skies, but temperatures will still remain well below normal, especially for the last week of February. We end the forecast period with a very weak area of low pressure over Quebec, Canada pushing a weak cold front over New England on Wednesday. We will see the chance for some snow showers during the end of the evening commute Wednesday evening.
