The capital Ottawa witnessed a thunderstorm on Saturday night, although this is unusual in February.

Ray Holly, a meteorology expert at Environment Canada, said there were some scattered lightning strikes in eastern Ontario between 8 pm and 11 pm on Saturday 

While thunderstorm activity was not officially recorded at the Ottawa Airport weather station, many residents commented on the thunder and lightning on social media.

Holly also said that a warm front is moving from the U.S. Midwest mixed with cold air in Ontario.

He added: "When this happens, it can destabilize the atmosphere and create a thunderstorm."

Ottawa experienced the hottest February 9 ever on Saturday, with temperatures reaching 9.9 degrees Celsius, and the previous high temperature record for that date was 7.4 degrees Celsius, recorded in 1990.

There is a possibility of record temperatures today, Sunday, and Environment Canada expects a rise up to 8 degrees Celsius. The record on February 10 is 7.2 degrees Celsius, recorded in 1966. However, cold weather is on the way.

Forecasts indicate a return to more seasonal weather on Tuesday.
