Residents of Dawson City, Yukon, should brace for a wet and unsettled week as thunderstorm risks and below-average temperatures coincide with the town’s Canada Day celebrations. Environment Canada’s latest forecast calls for showers beginning Monday afternoon and continuing through Friday, with drier conditions likely by the weekend, potentially complicating outdoor events planned for July 1.
As of 1:00 p.m. on Monday, June 29, conditions at the Dawson Airport were already signaling change. The temperature sat at 17.9 degrees Celsius beneath mostly cloudy skies, with a southwest wind at 18 km/h and barometric pressure falling, a classic sign that an active weather system is on the way.
The Environment Canada forecast issued Monday morning shows a 60 percent chance of showers Monday afternoon and Monday night, along with a risk of thunderstorms and a daytime high near 19 degrees. Tuesday will remain cloudy with another thunderstorm risk in the afternoon and a much cooler high of just 14 degrees.
By Wednesday, Canada Day, conditions are expected to improve only slightly under cloudy skies and a 40 percent chance of showers. The high will reach 16 degrees, well below the normal high of 23 degrees for this time of year. The unsettled pattern continues Thursday and Friday with periods of rain and highs between 14 and 16 degrees. A modest break is likely by the weekend, when a mix of sun and cloud returns with highs near 16 degrees.
The timing of the wet weather could challenge the City of Dawson annual Canada Day program. The downtown noon parade, family activities including face painting and bouncy castles, live music, and free food are all scheduled to run from 11:00 a.m. to 5 p.m. on July 1 at various outdoor locations. Organizers are likely encouraging attendees to bring rain gear and stay alert for updated forecasts.
Dawson City normally enjoys a brief but lively summer season, with July bringing an average rainfall of 49 millimetres and over 21 hours of daylight. This week’s cooler, showery pattern is not unusual for the Yukon, where afternoon thunderstorms often bubble up during warm months, but residents are still being urged to monitor Environment Canada for any thunderstorm watches that may be issued.
