A couple more days of miserable weather are in store before we move toward a nicer weather pattern. Conditions will gradually improve as the week progresses.
Monday will be another cloudy, cool, and even rainy day. A major upper-level low pressure system (as seen above) will be sitting over Southern Manitoba for most of Monday. This system will generate rainfall through much of Central and Southern Manitoba during the day, which won’t allow temperatures to rise much higher than the low or mid teens. Rainfall will be more persistent through Central Manitoba, where light rain will be present through much of the day. Areas further south are more likely to see showers in the morning, followed by more continuous rain in the afternoon and evening hours. Total accumulations in the south won’t be heavy, but as much as 5 or 10mm may accumulate by late Monday evening. Some light shower activity may persist in the Red River Valley and Eastern Manitoba on Tuesday morning, however Tuesday is generally expected to be a dry but cool day with high temperatures in the low teens.
Conditions will improve as we move later into the week with a high pressure system sliding into the region. The Wednesday to Friday period should be dry, barring perhaps an isolated shower or two, with temperatures rebounding back to near normal values. Wednesday’s temperatures should be in the mid to high teens in Southern Manitoba, while temperatures on Thursday and Friday will hover around the 20C mark. A series of low pressure systems are currently forecast to traverse Manitoba next weekend and as such the forecast for that time period is quite uncertain. More updates on the weekend weather will be available towards the middle of the week.
