Monday, August 11, 2014, 2:04 PM - "When our forecast team here at The Weather Network released our 2014 summer seasonal outlook, we warned of a warm and dry B.C., a cool and unsettled Manitoba and Ontario and a warm Atlantic Canada. Taking a look at the numbers and stats, the summer has been panning out just as predicted," said Weather Network meteorologist Dayna Vettese in a recent Insider Insight.

SUMMER SO FAR: A review of the 2014 forecast.

Like any summer, it's typically the warming temperatures that most people look forward to, but this year, there's been a clear divide.


"A persistent weather pattern this summer has been a trough of low pressure over central and eastern Canada and this has led to our unsettled and somewhat cool summer," explains Vettese.

Since May, major cities like Toronto and Montreal have only seen four days above 30°C. Parts of the Maritimes and the city of St. John's, Newfoundland on the other hand, haven't seen any to date.


Despite not reaching the 30 degree mark, it was the humidity in July that made things feel warmer across Newfoundland.

"Newfoundlanders are not necessarily prone to hot and humid summer, but July treated them to record breaking warmth and humidity," Vettese says. "St. John’s averaged about 25-26ºC for July for daytime highs where normally temperatures hovered around the 20-21ºC mark."

In fact, July 2014 is now the warmest month on record for St. John’s, Gander, Deer Lake and Stephenville. St. John ’s had a record 19 days above the 25ºC mark breaking the 1947 record of 14 days and three times the norm of 6 days in July above 25ºC.

"It’s not completely rare to have cooler summer," Vettese adds. "2009 was another summer where we struggled to make 30°C in central/eastern Canada."


Parts of western Canada have been in the opposite weather pattern, with a persistent ridge of high pressure dominating over them.

"This has led to a hot and dry summer for British Columbia," says Vettese.

Kamloops has already recorded over 30 days above 30°C while Osoyoos has already seen close to 40 days.

While great for beach goers, the extreme heat has kept fire crews across the west on high alert. Air quality advisories also remain in place as wildfire smoke impacts large sections of the British Columbia Interior.

"The rest of the summer should play out fairly similar to what we’ve been seeing," Vettese says. "Besides a few wobbles in the weather pattern, most things should remain about the same for the remainder of August."

Vettese says both coasts will hang onto the summer heat with the provinces in the middle struggling for some warm weather.
