"A slow moving area of low pressure over the central United States will bring an extended period of rain to parts of northern Ontario," Environment Canada warns. "The frozen ground has a reduced ability to absorb this rainfall."

Thankfully, the showers will have mostly disappeared by the weekend.

Meanwhile, southern regions will be remarkably sunny and warm this week with daytime temperatures reaching as high as 14 C on Wednesday in Toront.
