Another tough forecast, at least to start this forecast period. One of the big weather-makers to affect this forecast period will be just winding up on Wednesday. As a number of you know, I have to complete this forecast on Monday in order to meet the newspaper’s publishing deadline. As I write this there is still a lot of uncertainty as to how and exactly where a major storm system will affect our region. Currently it looks as if southern Saskatchewan, western Manitoba and the southern portions of central and eastern Manitoba, along with the northern half of North Dakota, will see some significant snow from this system.
The models point at snowfall amounts in some regions being as high as 20-25 centimetres from this system. While this system looks like it will add a fair bit of water to an already waterlogged drainage system, which will add to the flood threat, there is some good news. Cold air looks as if it will move in behind the system which will, at least temporarily, bring a halt to the spring snow melt. This cold air is forecast to stick around right through to the end of the month, with high temperatures running around -3 C and overnight lows in the -15 C range.
Looking a little further ahead, the weather models do show the spring melt picking up again later next week as daytime highs once again push above 0 C.
Highs:-6 to +8 C. Lows:-19 to -4 C.
Probability of precipitation falling as rain: 20 per cent.
