Light snow this evening will keep roads slippery

The storm is now mostly over with snow totals around 10 inches quite common in the Boston area. A few spots hit the 12 inch mark with areas south of Boston seeing less snow. For the season, Boston has seen about 45 inches of snow which is above the
typical average for an entire winter.

Since the winter of 2002-2003, 7 winters have now seen snowfall above the thirty year average. Even if we didn't get any more snow this winter, which is highly unlikely, this would end up being a snowier than average winter.

As we head into the evening the light snow will continue for several more hours. At times the snow may even become moderate especially from Route 495 eastward. The snow could accumulate an additional 2 inches in the Boston area by midnight. (A bit more north) This means when you finish clearing the walk or driveway this evening, there could be some additional snow to clean-up before you head to work Thursday.

The reason for the snow lingering is because a lobe of the storm in the ocean is still lingering back across eastern Massachusetts. The models have done a great job forecasting this final part of the storm. This is why we left snow in the forecast through the evening even though the heaviest is over. The map below shows the main storm off the coast with a smaller low over the New York-Pennsylvania border. The connection between these two storms is helping keep the snow around this evening. Eventually, the entire area will move east and the snow will end.

Most areas got received 8 and 12 inches of snow with less over the south shore, Cape Cod and Islands where 1-6 inches generally fell.

Remember, if you are clearing your driveway or car, just be aware there will be a coating up to an inch or two by midnight to re-clear. I know it might be frustrating to see the snow lingering through the evening, but we do have dry, cold weather which will remain storm free for at least the next three days.

As temperatures fall below freezing overnight any residual moisture will refreeze and slippery walking and driving will ensue.

Early Thursday skies will clear and I am expecting lots of sunshine for the next three days. There will be some clouds mixing with the sunshine at times as temperatures remain cold only in the upper 20s for the balance of the week.

Extended forecast
The next storm threat is Sunday afternoon through Monday. There will be a big storm developing. However, the amount of snow could be near zero if the storm stays hundreds of miles off the coast or a much more significant storm if the track takes the system closer to the region. It’s still several days away and impossible to know at this stage. The latest models keep most of the storm out to sea, however, there has been a trend this winter to have the models forecast a storm a week in advance, take it out to sea 3 to 5 days ahead and then bring it back. I am not ready to say this isn’t going to hit the area just yet and won’t be until Friday.
