Forecast: Cold with only slight chances of snow

Covering the period from January 15 to January 22

Well, last week’s forecast played out not too badly. We saw an Alberta clipper come through late last Wednesday and into Thursday and it ended up dropping a bit more snow than originally expected. While the cold air moved in over the weekend, as forecast, it ended up being pretty much right at the temperatures the weather models predicted: cold, but not bitterly cold.

For this forecast period it looks like we are going to experience a good old blast of winter as arctic high pressure dominates the weather across a good portion of western North America. Luckily for us, even though it will be cold, the centre of this cold air outbreak looks as if it will be to our west.

This forecast period will begin with arctic high pressure building in behind a weak area of low pressure that tracked through our region earlier in the week. This should bring plenty of sunshine along with cold temperatures. Expect both daytime highs and overnight lows to be running toward the lower end of the usual temperature range for this time of the year. By Friday, the weather models show a Colorado low developing, then quickly moving off to the northeast on Saturday. Currently, it looks like the strong ridge of high pressure over our region will keep the bulk of this system to our south, but it may give us some clouds and a few flurries or some light snow across southern regions. Temperatures will warm up a little bit with this system; expect highs on Friday and Saturday to be around -20 C with overnight lows around -25 C.

Once this system passes by, we will likely see a reinforcing shot of cold arctic air spill southward, bringing a return to clear skies and very cold temperatures by Monday and Tuesday next week.

Usual temperature range for this period: Highs, -23 to -6 C; lows, -33 to -15 C.
