It was a wet end to the Colonel By Day long weekend.
Ottawa received 38.4 mm of rain on Monday as a series of thunderstorms rumbled across the region.
The 38.4 mm of rain set a record for the wettest August 6 in Ottawa history. The previous record was 29 mm set in 1984.

The thunderstorm forced a ground stop at the Ottawa International Airport on Monday. Several departures were cancelled because of the storm.
Weather in #YOW is improving and operations will very slowly return to normal as ground crews try to catch up with big backlog. We apologize for the inconvenience and thank you for your patience. #OttCity pic.twitter.com/ed0uDvRYBB
