As predicted, records were broken yesterday, and Environment Canada gave an official weather statement about the event which you can find here. Records of note include West Vancouver at 30.3°C, Abbotsford hitting 34.2°C, and the hot spot in the province was Agassiz beating out a record from 1892 at 34.6°C. Well done Agassiz.
The temperature at Victoria International airport reached 30.7°C, which unusually enough was the cities warmest temperature of 2013! Our neighbours to our south in Seattle also had their warmest day of the year hitting 34°C.
Would you believe me if I said low pressure was responsible for this extreme heat? Although a ridge of high pressure was over the entire area, the added thermal trough to our southwest gave us that record breaking extra boost, allowing warm air from the interior to flow towards the coast. Here's my first attempt at a weather diagram, using a visible satellite map from yesterday afternoon.
The thermal trough will move into Washington state and that will usher in our typical onshore flow pattern for the next couple days. Weather models right now are hinting at yet again a more unstable atmosphere for Sunday and Monday. With the added convective potential, I can't rule out thunderstorms coming back into the picture by late Sunday.

Bonus Fact: The erupting volcano illusion.
At first glace the photo below Mt. Ranier in Washington State looks like an erupting volcano, but on further inspection you'll realize the volcano is casting a shadow on the clouds above. This effect is most commonly found during dawn, and the angle of the sun has to be just right, so the 'erupting volcano illusion' normally just lasts a few minutes.
