The national weather agency says the precipitation will begin as snow overnight, changing to ice pellets before turning into freezing rain - the result of a Colorado low crossing Southern Ontario.
After some quiet weather today with mostly cloudy skies and temperatures in the seasonable 30s, we have a winter storm on the way for Tuesday.
Some areas received more than a foot of snow, and meteorologists say more is on the way early next week. As it now looks, the heaviest snow may actually occur overnight and into early Tuesday morning. This will be an event that will impact commute times and travel for children getting home from school, rush hour traffic getting home from work, and 2nd and 3rd-shifters going to and from work Tuesday night into Wednesday. Flakes should start falling around 3 p.m.in Boston, the weather service said in forecasts early Monday.
The precipitation is expected to turn back into snow by Tuesday night, as colder air settles over the city.More news: Turkey building collapse death toll rises to 18

The National Weather Service has decreased forecast snow totals for Northeastern Minnesota, however, with only a 30 percent chance that Duluth, the Iron Range and most of the North Shore will see 6 inches or more. And another storm bringing snow and the potential for freezing rain was on tap for parts of the Seattle area.
How much is possible in an extreme case? The snow won't be around for long but it will be a burst of heavy snow - before it switches over to either sleet or freezing rain.
- Another round of snow, sleet and freezing rain is on the way.
