Special weather statement issued by Environment Canada:

 

Mild temperatures and potentially heavy rain today and tonight.

 

Periods of rain, heavy at times, are expected to begin this morning and continue tonight. Rainfall amounts in the 15 to 25 mm range are expected by early Friday morning. A few isolated thunderstorms are also possible today and tonight.

 

The heavy rain will combine with mild temperatures near 7 degrees Celsius to produce potentially significant snowmelt and localized ponding on streets and other low lying areas.

 

The heavy rain and mild temperatures are associated with a strong Colorado low that will transition across Northern Ontario tonight.
