Issued: Monday, March 15, 2010 Covering: March 17 –March 24

Spring sure seems to have moved in early this year, but I don’t think winter is going to give up this easily. After seeing some near-record-breaking warm temperatures over the last week – at least where the sun was able to make an appearance – it looks like we will see a bit of a cooldown during this forecast period.

The models have been fairly consistent in bringing down an area of arctic high pressure by the end of this week. Before this happens, it looks like an area of low pressure will track through central regions, bringing some showers or snow to more northern regions. At the same time a stronger low will be developing to our south. The models keep most, if not all, of the precipitation with the low to our south and east. Once these lows push by, things will be clear for cooler arctic air to move in.

By the weekend we should see high temperatures drop back down below 0C with overnight lows in the -10 to -15C range. These cooler temperatures will last until at least the end of next week, before the models show mild weather moving back in.

One thing we will have to watch is the forecast for an Alberta clipper to develop early next week. If this system does develop, we could see a stormy day around mid-week, with the chance of some areas seeing upward of 10 cm of snow.

Usual temperature range for this period: Highs: -8 to 7C. Lows: -21 to -3C.

Probability of precipitation falling as snow: 80 per cent.
