It might be spring, but winter’s still lurking

Spring has arrived — although the equinox was marked with stark contrasts in our weather.

Strong winds were felt right across Atlantic Canada, but there was more sunshine to be found in the Maritimes, with western Newfoundland and Labrador receiving snow and, for some, blizzard conditions.

Of course, just because it’s spring on the calendar doesn’t mean winter is finished with us. In fact, there’s more snow in the forecast.

A ridge of high pressure will be the main influence over the next few days, with onshore snow easing in Newfoundland and Labrador, but a low-pressure system developing near Colorado will influence the weather in Atlantic Canada near the end of the week.

I expect snow will move west to east across most of mainland Nova Scotia and New Brunswick through Thursday, then into Prince Edward Island and Cape Breton Thursday night into Friday and Newfoundland

through Friday. However, snow will likely mix with rain for parts of Nova Scotia, Prince Edward Island and southern New Brunswick.

Amounts are still quite uncertain due to this potential

mixing, but the best shot at amounts approaching or exceeding 15 cm will be northern New Brunswick, along with Prince Edward Island, Cape Breton and Newfoundland’s south coast if mixing is limited or doesn’t occur.

A second system will then strengthen over the midwestern U.S. Friday and Saturday and move through New England, then over or just south of the Maritimes Sunday. This carries greater uncertainty, but snow is possible, with mixing not being ruled out.

The benefit — it’s spring, so the snow shouldn’t hang around much longer. Perhaps one of these systems will be Sheila’s Brush?

Time will tell.
