Our week of sunny summer weather is coming to an end for a few days. An active cold front promises to cool things down with some heavy rain showers and possible thunderstorms.

Environment Canada has issued a special statement for the next 36 hours when severe weather could develop. Watch for severe thunderstorm warnings through Tuesday.

Heavy rain is expected to start in the Sault Ste. Marie region after 10pm Sunday and last all day Monday.

Significant rain continues today through Tuesday morning for areas north and east of Lake Superior. Rain developing over Northwestern Ontario Monday morning, the statement reads.

Showers from Lake Superior northeastwards towards Kapuskasing as a front remains nearly stationary over the area. These showers are expected to ease somewhat overnight however a developing low pressure system currently over South Dakota will spread rain over much of Northern Ontario early Monday morning. Total rainfall amounts of 25 to 40 mm are expected by Tuesday morning. Locally higher amounts may be possible due to thunderstorms where rainfall amounts may exceed 50 mm over the two day period. Rain will taper off in Northwestern Ontario Tuesday morning and late Tuesday for Northeastern Ontario.
