Forecast discussion: Eastern Massachusetts has been getting hit from a band of ocean effect snow showers, along with a frontal boundary which is bringing Arctic air. Now, New England is bracing for a Nor’easter Thursday night, followed by bitterly cold temperatures Friday evening into Saturday. Milder temperatures are in store for early next week.
At this time, a low pressure system has developed and is beginning to intensify off the coast of Maryland. Current radar shows some light snow over eastern Massachusetts as of 8:30 p.m. However, southern and central Rhode Island are already seeing moderate to sometimes heavy bands. Also, strong winds are beginning to appear on the Cape, as buoy reports show winds of 25-30 mph off Boston Harbor. Seas are already at about 12-15 feet.
For most of Massachusetts, we are currently under a Winter Storm Warning until 10 a.m. Friday morning. Several cities and towns have parking bans in effect, and several towns have cancelled school. Some churches and many businesses have also closed for tomorrow. To see a complete list of closings for the Boston area, click here. For the extreme eastern coastline, along with the Cape, they are under a Blizzard Warning until 11 a.m. Friday.
Some parts of the state will be seeing snowfall tonight at about an inch per hour in heavier snow bands. Also, winds will be increasing, so we will be seeing blowing and drifting snow. So, if you absolutely have to travel by car tonight, please be extra careful. Give yourself extra time to make it to your destination. Already, parts of Peabody and Rowley have unconfirmed reports of 10-16 inches of snow.
By the time Boston wakes up, we should see anywhere from 12-18 inches on the ground. The area around Essex County could see up to two feet of snow. Southern Plymouth County will see 8-12 inches, while the Cape and Islands will see 5-8 inches. However, as you shovel and blow you way out of the driveway, please dress in layers. Wind chills will make it feel like 15-20 below in the morning, and high temperatures will only make it into the lower teens. By Friday night, it will be just bone chilling cold, as temperatures will plummet below zero. We may even break a record for Friday night, as the all-time low was 1 degree in 1904. This would be the first time Boston saw temperatures reach zero since January 24, 2011.
By Saturday, it will feel downright balmy, as high pressure brings mostly sunny skies and high temperatures will reach the upper 20’s. By Sunday, southwest winds will help bring milder air back to eastern Massachusetts, as temperatures climb into the upper 30’s. But, we will see another round of precipitation, albeit it will be rain. The rain showers may change over to snow showers by Monday afternoon, as a cold front passes through the state. We will once again see bitterly cold air behind the front move over the region.
We will see dry weather for Tuesday and Wednesday, with temperatures only in the 20’s. By next Thursday, a weak low pressure system will bring some possible snow showers by the evening.
