Issued: Monday, April 19, 2010 Covering: April 21 –April 28

All I can say to start this forecast period is that it’s going to be pretty hard to beat the incredible weather pretty much all of agricultural Manitoba saw last weekend and the beginning of this week. Thanks to a ridge of high pressure and a very dry air mass, most places recorded temperatures in the low 20s for highs, but with the lack of moisture overnight, lows were still falling below freezing.

It looks like the nice spring/early-summer weather will continue for at least the next week or so. I say “early-summer” weather as it took until the first week in June last year for us to see this type of weather! The forecast for the next couple of weeks has it looking more and more like April will follow March with well-above-average temperatures.

The main flow across North America will continue to be split, with energy flowing well to our north and to our south. A fairly strong storm system is forecast to move through the southern stream late this week but all indications have this system staying well to our south. This means high pressure will continue to dominate our weather and we should stay on the sunny side (areas closest to the border may see some clouds) with highs continuing to run in the 15 to 20 C range.

The weather models have been trying to back-door in a cool area of arctic high pressure early next week, but each new model run is pulling back on this feature. So it looks like for next week we will continue to see plenty of sunshine and continued mild temperatures.

Usual temperature range for this period: Highs: 6 to 20 C. Lows: -4 to 6 C.

Probability of precipitation falling as snow: 25 per cent.
