This week will start out with some nice hot weather, but then rapidly cool off from there. Fall weather appears to be here to stay.
Monday will be one of our last hot days of the year as temperatures climb up around the 30C mark in Southern Manitoba. However, the heat won’t last long, as a cold front will sweep through on Tuesday, bringing cooler weather for the rest of the week. Temperatures from Tuesday through Friday are expected to be fairly typical for mid-September, with values in the upper teens or lower twenties expected. No significant precipitation is expected for the first part of this week, though an odd shower is possible.
At this point most long-range models don’t give a clear picture for how September will proceed temperature-wise. For the most part is looks like we’ll see many normal weather, with some ups and downs here and there. A more interesting long-range weather feature to watch is the development of El Nino conditions in the Pacific Ocean. Most long-term forecasts are calling for the development of weak El Nino conditions in the central Pacific Ocean for this fall and winter. El Nino events tend to bring warmer and drier than normal weather to Western Canada. The stronger the El Nino is, the greater the chance we’ll see a warmer and drier than normal winter here in Southern Manitoba. As we move into winter you will no doubt be hearing more about this topic.
