Forecast discussion: Monday brought a little bit of reality back to Boston. After temperatures hit the lower 50’s, we returned to winter, as we saw a little bit of light snow during the overnight. We will return to seeing some spring like weather for Tuesday. Then, a low pressure system is going to bring a lot of precipitation to the area on Wednesday.
For tonight, we will begin to see warmer air return to Southern New England. This is due to a frontal boundary passing through Northern New England at the moment. The low’s center will remain over Canada, but the warm front will help increase our high temperatures into the lower 50’s, despite limited sunshine. We may see a spot rain or snow shower passing over the capital city during the early morning. Otherwise, we will have limited sunshine going into early Wednesday morning. Then, we will be hit with a strong storm system that will make its way into the Mid-Atlantic by Wednesday afternoon.
At this time, the computer models continue to agree that the low will track to the south of us, but will continue to remain in the warm sector. So, temperatures will reach the upper 40’s, and the precipitation will start off as showers. The precipitation will become heavier by the evening commute, so we could see isolated street flooding. We could see a half inch to an inch and a half of rainfall before midnight. By early Thursday morning, the cold front will begin to come through, and temperatures will drop quickly. We will see a changeover to sleet mixing with rain by midnight, before changing over to all snow around 4 a.m. However, the snow will be light, and I am not expecting any heavy snowfall amounts. The most an area might see would be about 3 inches by Thursday evening. Then, temperatures will be quite cold Thursday night, as we could be close to breaking an all-time record for low temperature in Providence.
Temperatures will slowly warm up back again during the weekend, with a low pressure system possibly creating some showers for Saturday. It will be quite mild, as temperatures rise into the middle to upper 40’s. But, a cold front behind this low will bring back winter, as temperatures during the day will fall back into the middle 30’s for Monday.
