Okanagan waits for summer weather, while eastern Canada deals with heat waves

Clearing conditions are expected for the first few days of this week in the Okanagan, but more showers are expected by Thursday.

More changing weather conditions are in the forecast this week in the Okanagan as temperatures continue to struggle to reach the seasonal norms this time of year.

Environment Canada meteorologist Lisa Erven says the whole country has been stuck in a pattern consisting of a broad trough over western Canada and a ridge of high pressure over eastern Canada for the past month and a half.

“The country has been basically split in two, with the west under a broad trough of low pressure, getting those cooler temperatures and more showery conditions, versus eastern Canada, which has been stuck in the heat for the past several weeks,” Erven says.

A weak ridge of high pressure is building for the initial part of this week that should result in a few days of sunny skies and warming temperatures. However, another low pressure system is expected to head our way for Thursday and Friday, bringing the usual showers and cooler temperatures.

Erven says the longer range forecast hints at improving conditions over the next two weeks, but there’s still not enough solid evidence to say the present pattern will change significantly.

“The summer has been very dynamic. With how persistent this trough has been, I’d like to see a strong switch to a dominating ridge of high pressure before I could say, ‘Here comes the  heat,’” Erven says.

Ontario did experience a return to normal temperatures on the weekend, according to the Weather Network, but the change is expected to be short-lived as another heat wave is expected by the end of the week.

In the Okanagan this afternoon, July 13, expect sunny skies with a high of 23 Celsius in Vernon and Kelowna, and 25 C in Penticton. It will be breezy, with winds northwest at 20 km/h gusting to 40. Clear conditions and a low of 10 C is expected overnight in all three cities.

Tuesday should be sunny with a high of 27 C and a low of 14 C under clear skies overnight.

Another sunny day is anticipated Wednesday with a high of 27 C and a low of 15 C.

Cloudy and unsettled conditions return Thursday with a 30 per cent chance of showers as the high reaches 26 C. Clouds and a 60 per cent chance of showers are expected overnight with a low of 15 C.

Friday should see a 60 per cent chance of showers with a high of 37 C and an overnight low of 15 C.

There’s a 30 per cent chance of showers overnight Friday.

The weekend looks promising at this point, with a forecast calling for a mix of sun and cloud and highs of 28 C for both Saturday and Sunday.

Normal temperatures for this time of year in the Okanagan are highs of 28 C and lows of 14 C.
