Showers could break Vancouver's run for driest month

There is a chance of showers at Vancouver International Airport around midnight Wednesday, as a spinning low-pressure system moves north into B.C.'s South Coast, says CBC meteorologist Johanna Wagstaffe.

The Fraser Valley and B.C.'s coastal mountains will see a good chance of thunderstorms Wednesday afternoon, but they should stay clear of Vancouver airport until the evening.

The risk of precipitation is low, but it would ruin Vancouver's all-time driest July (since records began 76 years ago) if we get more than trace amounts of rain.

Thursday morning will likely start off cloudy with a risk of showers for Vancouver airport. We may see some afternoon sun before the showers return Friday.

Showers will linger through the weekend between sunny breaks, before summery weather returns for the holiday Monday.
