Dismal weather drowned two rainfall records

The rain wasn’t going away over the weekend as a record amount of precipitation fell over the city.

Environment Canada meteorologist Doug Lundquist said from Kelowna, B.C. this morning that a record was set both Friday and Saturday.

On Friday, 18.9 millimetres of rain fell on the city, breaking the previous Sept. 5 record set in 1991 of 15 millimetres.

Then, on Saturday, the former Sept. 6 record of 10.4 millimetres of rain, set in 1963, was shattered when 17.2 millimetres fell on the city.

A further 8.1 millimetres soaked the city on Sunday, but that was not enough to break any records.

The unending precipitation, Lundquist explained, was caused by a combination of cold air moving in from the Northwest Territories with warm air coming in from the other direction.

The two weather systems met in Whitehorse – bringing three straight days of rain.

As Lundquist explained, what makes the weekend’s weather a “big deal” was that there was not just one daily record broken, but two in a row.

While precipitation levels have been about average and the temperature working out to be about half a degree above average throughout the summer, Lundquist acknowledged there may be a perception that it’s been been a cooler summer with more rain than usual.

Perhaps it’s the more recent precipitation that’s affecting the outlook of Whitehorse residents.

The last day there wasn’t anything less than a trace of precipitation in the city was Aug. 29.

Over the three months of summer, rainfall has been relatively close to the average with 28 millimetres in June compared to the average 32, 53 millimetres in July compared to the average 38 and 26 millimetres in August compared to the average 36.

While there’s a 60 per cent chance of rain Wednesday and 30 per cent chance on Thursday, Lundquist said Whitehorse residents may enjoy sunnier skies and warmer weather next weekend, when temperatures are expected to rise into the mid to high teens.

That would be above average, and also fits in with the long-range forecast that shows warmer temperatures in the weeks ahead as well as a higher chance of precipitation.
