Arctic high pressure built into our region last weekend and into the early part of this week as expected, but what wasn’t expected was the strength and resultant cold air. Luckily, this arctic high will pull off to the east by the middle of this week, allowing milder air to move in again.

Several large systems will have an impact on our weather this forecast period. As arctic high pressure slowly pulls off to the east, a deep area of low pressure is expected to form over the central U.S. This low should be kept well to our south by the arctic high, but as usual, it will be something to watch. At the same time, energy from a large area of low pressure off the southern coast of Alaska will begin to push onshore over Northern Canada. With low pressure developing to our west and high pressure to our east, we should see a fairly strong southerly flow develop by Thursday or Friday this week. This will help to boost our temperatures, with highs making it into the low teens by Friday and possibly upper teens over the weekend. Combine this with plenty of sunshine and it will definitely feel very much like spring.

Some of the Pacific energy will move across the Prairies early next week. The weather models are having a tough time figuring out just where the main energy from this system will go, but there will be a good chance of some scattered showers and even the odd thundershower late on Monday and into Tuesday as the system sweeps through. Temperatures will cool down a little bit behind this system, with daytime highs cooling to the +10 C range on Tuesday and Wednesday, and overnight lows around the 0 C mark. I don’t see any outbreaks of really cold weather, though, as arctic air looks to stay well to our north.

Usual temperature range for this period: Highs, +1 to 14 C; lows, -8 to +2 C. Probability of precipitation falling as snow: 50 per cent.
