An interesting week last week, as the predicted Friday storm system became much stronger than anticipated, bringing rain and some snow to southern and eastern regions. Then the second storm system predicted for early in the week did develop, but it was not as strong as expected and remained well to our south.

During the first half of this forecast period, high pressure will dominate our weather, bringing sunshine and mild temperatures. Daily high and low temperatures should be at the upper end of the usual temperature range for this time of the year for most of this week. Over the weekend an area of low pressure looks to track across the northern Prairies. This low could bring some showers or flurries to northern agricultural areas on the weekend. For southern regions we will see temperatures cool down a little bit as a cold front pushes through behind this low.

For the first half of next week the models are once again trying to develop a large powerful low to our southwest. Currently this low is forecast to bring rain to southern regions on Monday or Tuesday, with wet snow possible over western regions. Keeping in mind how these lows have tended to stay to our south so far this year, confidence in this system hitting us is not that high, but it is something to keep an eye on should it develop.

Beyond this system, the weather models show a bit of a cooldown as high pressure slides in from the north, but under the strong spring sunshine, temperatures look to quickly modify back to above average.

Usual temperature range for this period: Highs: 2 to 14 C. Lows: -8 to 2 C.

Probability of precipitation falling as snow: 40 per cent.
