Residents of Owen Sound should prepare for a significant temperature shift this weekend as a cold start leads into a much milder Sunday, according to Environment Canada.

Saturday, May 2, will begin with chilly conditions and a morning wind chill of -6°C. While skies will clear to become partly cloudy, the high will only reach 5°C. Residents should be prepared for the coldest point of the weekend on Saturday night, when clear skies will allow temperatures to drop to -7°C.

The weather is expected to take a dramatic turn on Sunday, May 3, as conditions warm to a high of 12°C. While the day will feature a mix of sun and cloud, there is a 40% chance of showers. Cloudier conditions are expected by the evening, with the likelihood of showers increasing to 60% and a low of 6°C.

For those planning to head out onto the water, the Georgian Bay marine forecast indicates northwest winds of 10 to 15 knots throughout Saturday, with wave heights between 0.5 and 1 metre. Winds are expected to become light by Sunday, and the bay remains clear of ice.

While the weekend will see a 17-degree swing in temperatures, Environment Canada notes that these conditions remain within the normal range for this time of year, with historical averages for May typically reaching highs of 14°C and lows of 4°C.

Drivers and those with outdoor plans are encouraged to dress in layers to accommodate the changing weather and to remain mindful of fluctuating conditions throughout the weekend.
