Temperatures reached the 50s on Friday, giving us a feeling of spring. But today, strong winds are bringing in much colder air from Canada and this will set the stage for a wintry storm early this coming week.
Low pressure will move up into the great lakes on Tuesday as a secondary storm reforms south of New England.
These scenarios typically bring snow or even sleet and snow at the onset, which often further mixes with or even changes to rain before the storm ends.
The snow will hold off until after the morning commute on Tuesday but will be here before the evening one. You should plan on slower travel Tuesday afternoon.
This will be a light or moderate snow storm. It’s the type that will cause delays and some cancellations, with a possible impact on flights at Logan airport. Anyone that does have travel plans Tuesday will want to check ahead with their airlines, and I expect a few flights to be completely canceled. In terms of impact to school, there may be early dismissals on Tuesday, but since the snow really won’t be underway until late morning and early afternoon, there shouldn’t be any reason to cancel the entire day.
The snow will quickly mix with sleet and then change to rain Tuesday night and early Wednesday before coming to an end. Since the storm is still several days away, accumulation predictions are uncertain. A warmer system would obviously lower the amount of snow and a colder system would raise it.
Northern New England ski areas should do particularly well out of this storm with six to 12 inches of snow likely. The greatest chance for more than 4 inches inches of snow in southern New England will be north and west of Interstate 495 and toward the New Hampshire border.
Greater Boston will probably see 1 to 4 inches of snow. There likely will be mixing as well. If this turns out to be more sleet again, then we are looking at even less snow. Obviously I’ll tighten up that range closer to Tuesday, but that will give you an idea of the type of storm were talking about at least 72 hours before it begins.
After this storm, a warmer system is forecast for late next week, likely bringing rain that would wash away much of the snow. The winter continues to be a dud for those who love lots of cold and snow, it’s not over yet, but time is running out.
