Forecast: More sun than clouds, but cool

Covering the period from April 8 to April 15

This issue’s map shows the total amount of precipitation that fell across the Prairies during the seven days ending April 1. This map shows the first wave of precipitation from last week’s storm system. Western and central regions saw upward of 15 to 30 mm of water-equivalent precipitation during this first wave. The second wave (not shown on this map) brought similar amounts to central and eastern regions.

If you recall last week’s forecast, I didn’t have a lot of confidence in the weather models, but as it turned out, they did a fairly good job. The one thing they missed out on was the intensity of the snow with the storm system that brought a widespread 10 to 20 cm of snow last Wednesday to Friday.

For those of us stuck working from home, practising social distancing and wishing we will see some nice warm weather, I’m afraid we are out of luck for this forecast period. While the weather models are struggling a little bit with the finer details of the medium-range forecast, they seem to be in good agreement that it will be a colder start to the month.

This forecast period will begin with an area of low pressure tracking by to our north. Behind this low, modified arctic air will move in, bringing sunny skies and cool temperatures. Expect daytime highs on Thursday and Friday to be in the 3 to 5 C range with overnight lows around -10 C. We should see a bit of a warm-up late in the week as another area of low pressure tracks by to our north. The warm-up looks to be short lived as a cold front is forecast to sweep through over the weekend, bringing a return to cooler-than-average temperatures.

High pressure then looks to dominate our region for the first half of next week. Temperatures will start off cooler than average, with daytime highs struggling to reach 5 C and overnight lows around -8 C. With the high providing clear skies and plenty of sunshine, the strong spring sunshine should allow temperatures to slowly increase each day. Forecasted highs by Wednesday are around 8 C, but that will depend on whether there is snow cover still left around.

Usual temperature range for this period: Highs, 0 to +12 C; lows, -11 to 0 C.
