We ride the temperature roller-coaster

By the time you read this forecast, we’ve either just dodged a big winter storm to our south or are just starting to dig ourselves out of it! The weather models have been pretty consistent with bringing a strong, slow-moving storm system across the northern U.S. during the middle of this week. Whether this system hits us or not, we’ll definitely see a major shot of cold air later in the week.

As the strong area of low pressure pulls out to our northeast on Thursday, we’ll see a large area of arctic high pressure begin dropping southward. The centre of this high looks like it will track through Saskatchewan and then move through the Dakotas over the weekend. This should keep us from seeing the really cold temperatures, but we are still going to be cold. In fact, with the departing low to our east and strong high pressure to our west, it looks like Thursday and Friday will also be fairly breezy. Combine these winds with temperatures in the -15 to -20 C range and wind chills will become an issue, with values expected to drop into the -30s.

The cold weather looks like it’ll stick around for at least the first half of next week as another arctic high drops southward, bringing with it a reinforcing shot of cold air. Highs are only expected to be in the -16 to -20 C range to start the week, with overnight lows in the -25 to -30 area, near the bottom end of the usual temperature range for this time of the year.

Looking a little further ahead, the weather models are keeping cold air in place right through to the weekend before another storm system is forecast to move in off of the Pacific. This will allow for some milder air to begin moving back in. Along with the milder temperatures will come the chance for more snow!

Usual temperature range for this period: Highs, -17 to -1 C; lows, -27 to -9 C.
