March will begin with snow and plenty of it, says Environment Canada, and it warns that Tuesday afternoon’s rush hour won’t be pretty.
Most of the snow will fall overnight and the total may reach 25 centimetres.
The details:
“Snow, heavy at times, is expected. The snow will begin late this (Tuesday) afternoon and intensify late this evening with the heaviest amounts of snow forecast for tonight.
“Total snowfall amounts near 25 cm are likely by Wednesday morning.”
We may also get gusts up to 50 kilometres an hour, which will make visibility poor, sometimes without warning.
Environment Canada warns: “Consider postponing non-essential travel until conditions improve. Rapidly accumulating snow could make travel difficult over some locations.”
Once again, we can blame moisture from Texas and its neighbouring southern states. The jet stream brings cold air from the U.S. Plains states south to areas near the Gulf of Mexico, where they soak up moisture.

Then the jet stream swings north and east, toward Ontario and Quebec.
By early Tuesday morning, snow was falling across Michigan and moving well into Southwestern Ontario, with rain farther south in Ohio. All of it is moving east.
Meanwhile, Environment Canada’s spring seasonal forecast is out, and it’s a warm one.
Source is Environment Canada. Canada can expect above-average temperatures (yellow and orange on the map) for March through May.
Issued Sunday, the outlook for March, April and May shows above-average temperatures across the entire country.
Spring is already getting closer: Ottawa is now getting 11 hours and 10 minutes of sunlight each day, a gain of nearly two-and-a-half hours since the shortest day of the year, Dec. 21.
It’s the same amount of daylight as we had last Oct. 11.
As well, the sun is rising higher each day. When winter began it reached a maximum of 21 degrees above the horizon (where 0 is a flat horizon and 90 is straight up.) Now it reaches 37 degrees at noon.
Month-end statistics from February show it was a mild month on average, except for five nights in a row when the temperature dropped below minus-20 C (Feb. 11 through 15). The average high for the month was minus-3 C and the average low -13.3 C.
