For tonight, a line of showers is expected to materialise across Manitoba along the low-level jet. This is expected to affect Winnipeg by sometime this evening then continue overnight and end sometime Saturday morning. 2-5 mm of rainfall is possible with locally higher amounts under any heavier bands. The low-level jet (llj) is expected to weaken as it moves east also dissipating the rainfall, therefore areas east of Lake Winnipeg may not even get a drop of rain tonight.

On Sunday, some showers and storms will be possible, especially in western areas of the province and along the US border.
Beyond that, I wont go into much detail due to the uncertainty. At least a small chance of scattered showers and storms looks possible almost every day next week. Some models have also been hinting at a more organised system south of the border to end the week for a few runs now. It's too early to say just how this will impact Manitoba.
Something you will notice in the next several days is the increased humidity as dewpoints rise into the low teens. Overnight lows will be quite mild, likely remaining in the teens, thanks to both the increased humidity and increased cloud cover.
