Forecast discussion: After seeing the changeover to snow earlier Thursday morning, we have accumulations over central and northeast Massachusetts. Places like Mansfield and North Attleboro have seen about 3 inches. Norton, MA has just checked in with 8 inches. As we progress through tonight and into Friday, this is the time we will see heavy snowfall. Also, some areas may see some power outages, due to the combination of wet snow on power wires, as well as strong wind gusts during the overnight hours.
As the low pressure system continues to bring strong winds to the region, especially along the coastlines, the heavier bands will move from east to west. The National Weather Service has a Winter Storm Warning in effect until 1 p.m. Friday for all of eastern Massachusetts. Plymouth County has a Winter Weather Advisory, meaning they are forecasting less than six inches of snow. The coastline, Cape, and Islands have a High Wind Warning in effect, until the same time as the other advisories. Although this area will see more rain than snow, strong winds from the low pressure system could create wind gusts of 60-65 mph. This could create high power outages.
Also, due to the strong northeast winds, a Coastal Flood Warning is in effect, due to strong waves crashing into the beaches and land. Also, high tide will also help increase wave heights.
The snow will begin to taper off by the late afternoon, and will come to an end before midnight. We will still have mostly cloudy skies, with some partial clearing on Saturday. I have put my final snowfall totals down in the 72 hour forecast. But, with warmer temperatures into early next week, the snow should quickly melt.
An upper level ridge will move over the eastern U.S. early next week. This ridge will allow warmer air to filter into Southern New England. So, we will see mostly sunny skies for Sunday and Monday, with high temperatures rising into the upper 40’s. In fact, we may reach 50 degrees by Tuesday afternoon.
However, we will begin to lose the sunshine once again. A cold front will bring some showers into the state. Right now, the American model is moving the front quite slowly, while the European model moves the front a little faster. Right now, I will forecast showers developing by the morning commute, and ending by the late evening. But, I may change the timing of the shower activity if the European model keeps consistency over the next few days.
After the cold front passes, our temperatures will return to normal. Colder air behind the front will bring our high temperatures back to seasonable conditions, which would be the lower to middle 40’s.
