After a week of summer-like weather, conditions will return to reality. More fall-like temperatures are expected this week along with some rain.
Today will be mainly cloudy with a chance of an isolated shower or drizzle. Low-level moisture under a strong ridge of high pressure will be responsible for the cloud. We may see some clearing late in the day, but that won’t change the day’s expected temperatures. High temperatures today will be in the low teens, with a light easterly to south-easterly wind.
Tuesday will remain on the cool side, with temperatures in the low to mid teens. Despite the fact that these temperatures may seem cool, especially compared to last week, they are actually near normal for this time of year. Our next chance for rain will begin on Tuesday night as a compact, but intense, low pressure system spreads rain over southern Manitoba.
The aforementioned low pressure system will be the dominant weather feature on Wednesday. It is expected to bring light to moderate rainfall to southern Manitoba for most of Wednesday. It is too early to predict how much rain will fall, but at this point 5-10 mm looks most probable.
The long range forecast looks very fall-like. Current modelling suggests we will see normal to below-normal weather as we move into October. That means temperatures in the low teens, plus or minus a few degrees.
