Residents in Mississippi Mills, Ontario, should prepare for a return to winter weather as snow and freezing temperatures are expected to move into the area starting March 13, 2026. According to Environment Canada, the community will see about five centimetres of snow on Friday followed by a significant drop in temperature over the weekend.
The weather shift begins Friday with increasing clouds around noon followed by steady snow. While the daytime high will sit around -1°C, temperatures will continue to fall, reaching a low of -10°C by Saturday night.
These conditions may create slippery surfaces and travel delays for local drivers as the region moves out of a relatively mild mid-week period. The return to colder weather means that any slush or melted snow on the ground could freeze quickly, making roads and sidewalks hazardous.
The Mississippi Valley Conservation Authority is continuing to monitor local water levels and watersheds during the change in weather. The authority had previously issued a flood outlook on March 4, 2026, after warmer temperatures and rain caused concerns about runoff earlier in the month.
