The weather over much of North America played out a little differently than expected last week as two major storm systems “took control” of the weather. The first system was the incredibly strong nor’easter that hit much of the northeastern U.S. and southeastern Canada last weekend. The second system was the strong Colorado low that missed us to the south. Both of these systems ended up changing the overall weather pattern, making last week’s forecast for our region a little unreliable.
It looks like things will quiet down a little for this forecast period. The weather models show an area of low pressure sliding out of the northwest during the middle of this week. Much like the past three or four systems, it will likely bring a few centimetres of snow late Wednesday and possibly into Thursday morning. Behind this system colder air will try to move in, but the coldest air looks to stay to our north and east.
Typical winter weather will be over the region to start the weekend, with mainly sunny skies and high temperatures around the -16 C mark. Another area of low pressure is forecast to drop southeastward late in the weekend and depending on the track of this system, either southern or central regions could see another few centimetres of snow.
Once again it doesn’t look as if any really cold air will move in behind this system. Monday will be the coldest day, but by the middle of the week, temperatures should moderate, with high temperatures expected to be in the -12 C range.
Usual temperature range for this period: Highs, -18 to -3 C; lows, -30 to -12 C.
