Residents in Cornwall can look forward to a stretch of clear and sunny weather this week, providing a break from the stormy conditions that moved through the region earlier in April. According to Environment Canada, there are no weather alerts in effect as the community settles into a more stable pattern.

Sunny skies are expected to dominate through Saturday, April 25, with daytime highs ranging between 12°C and 14°C. While the days will be bright, those with gardens should take note of chilly overnight temperatures. Frost is expected as the mercury drops to between -1°C and -2°C on Thursday and Friday nights. According to the Old Farmer’s Almanac, the average last spring frost date for the area is May 7, making these cold overnight lows normal for this time of year.

Following the current stable period, the weather is expected to change early next week. Cloudier conditions with a 60 percent chance of showers are in the forecast starting Tuesday, April 28.

This calm weather follows a period of unseasonably warm temperatures that saw the region reach near 20°C earlier this month, accompanied by thunderstorms and gusty winds. Current conditions, as of 9:00 AM on April 23, show a temperature of 9°C with rising barometric pressure, signaling that the pleasant weather will hold through the end of the work week.
