Dry Saturday Morning, Snow Arrives Around Dark

As I look at the latest charts for our Saturday night storm a few things are becoming clearer. First, snow amounts will be very low along the coast. Warm air will come onshore at the low and high levels of the atmosphere by the middle of the evening so any snow will quickly change to sleet and rain.

Because the roads are cold, what snow does fall will quickly stick to untreated surfaces. This means travel will be disproportionately poor for the amount of snow that falls.

The timing of the snow arrival is 4PM to 7PM from southern Worcester County to northern Essex County. Because of the wintry weather a Winter Weather Advisory Has been issued for most areas away from the immediate coast.


I’ll update the forecast during the morning and you can follow more of my thoughts on the forecast on Twitter @growingwisdom

Day two of the New Year continues to feature bare ground across the region, but this is going to change tomorrow evening, especially away from the coast. It might not last, but it will look wintry for a few hours. Last year we were in the throes of very cold air and a major snowstorm which dumped 1 to 2 feet of snow across the region. Back then some towns across Cape Ann saw over 2 feet of snow, but it was so cold the snow was easy to move around. While snow is in the forecast, I don’t see any major or even moderate snow events through the 10th of the month at least.


Above is the chart showing the highs, lows and snowfall for last January. Notice Boston saw three days in a row of temperatures close to zero. The thermometer at my house reached 7 below zero during this time The saying “it’s too cold to snow” certainly did not apply during that storm.


Today won’t be as cold as the past couple of days, but a brisk wind will make it feel quite chilly, especially around open spaces or in Boston as the wind comes around buildings.

Sunshine starts the weekend, but by the end of the day snow will breaking out across the region.

While it’s been cold enough for snow for a nearly a week, our next storm is going to once again drag very warm up from the south and limit accumulations. I am forecasting a coating to 2 inches for most of the area. West of Route 495, there is a Winter Storm Watch posted for up several inches of snow and up to a quarter inch of ice that could accumulate on top of that snow.


This amount of freezing rain isn’t a major event, but will cause hazardous driving tomorrow night, perhaps lasting into early Sunday morning. I don’t expect enough icing to cause power issues or tree damage. This isn’t a bit storm, but in a winter without much snow or ice it’s significant.

The rain will come to an end during the morning Sunday and temperatures will rise to the 50s along the coastal plain and interior back about 20 miles from the coastline. Further west, highs will stay in the 40s, with 30s confined to the Berkshires and extreme northwestern sections of Worcester County.

Behind the storm another push of arctic air will move into the region. I expect many of us to see single digit low temperatures during the middle of next week. Many areas will be back to bare ground after the rain, so temperatures won’t be as cold as they could be with deep snow cover. Even so, it’s going to be a very cold couple of days.
