Forecast – for Feb. 3, 2011

Last week’s forecast played out pretty much as anticipated. The only fly in the ointment was that last Friday’s system ended up dropping more snow than expected. For this forecast period, it doesn’t look like we will see much snow, but there will be a fair bit of cold air to deal with.

The area of high pressure which brought the cold start to the week will be well to our south by the second half of this week. This will place us in a good westerly flow on Thursday and Friday which should help to warm things up. We should see temperatures around -5 C for highs, with some of the higher elevations over western regions possibly seeing highs near the 0 C mark.

Over the weekend we will have to watch another system that is forecast to drop out of the northwest. While this system is similar to last Friday’s system the models are not intensifying the system as much and are taking it on a slightly different track. They have the system remaining fairly large but rather weak and are sliding it in a more westerly direction before moving it off to the east. This should result in clouds and occasional light snow over the weekend but it doesn’t look like there will be more than a few centimetres with this system.

Arctic high pressure is then forecast to build back in by Monday of next week, bringing sunshine and cold temperatures once again. This high doesn’t look like it will bring bone-chilling cold air but it will still be cool. We should expect highs around -15 C with overnight lows in the -25 to -30 C range.

Usual temperature range for this period: Highs:-20 to -4 C. Lows:-32 to -13 C.
