From thunderstorms to snow, spring snaps back into reality across B.C.

The sneak peek of summer in B.C. will come to an end soon as the upper-level ridge will break down towards the end of the week, bringing more reflective temperatures of the season, along with rain and high-elevation snow

Everything that has a beginning has an end, B.C.

The warm, summer-like conditions that have been occurring in British Columbia recently will persist for a bit longer. As an example, Castlegar experienced temperatures of 30.6°C on Wednesday. However, this warmth will not endure.

A temporary change in weather patterns is expected for this weekend and the following week, which will serve as a harsh reminder to residents that it is still a transitional season.

Alongside the cooler temperatures, wet weather will return, providing 20-40 mm of rain and the chance of high-elevation snow.

After temperatures climbed to 30°C for some across the province, a harsh reality will slip back into B.C.’s weather pattern this weekend with cool rain and high-elevation snow as the current ridge breaks down.

Temperatures climbed into the mid-to-upper 20s across the province of B.C. on Tuesday, with some daily high temperatures recorded. Even a couple stations reached 30°C, bringing a taste of early summer-like warmth. Temperatures in the upper 20s will continue through the remainder of the week for the southern Interior.

The heat has also fuelled some thunderstorm potential for the last few days across the southern Interior, and will continue while the heat remains in place.

The ridge of high pressure responsible for the warmth will break down across B.C. towards the end of the week and into the weekend, replaced by a trough swinging down from the northern Pacific and an upper low migrating north from the California coast.

As freezing levels fall into the weekend, precipitation is forecast to transition and fall as snow at the alpine peaks across the south, even reaching some of the mountain passes at times throughout the weekend.

Impacts from snowfall will be minimal unless residents have plans to travel from the coast to the Interior, depending on the day, and may encounter some mixing or wet snow through the southern passes.

Wet and cool weekend ahead

Cool rain along the coast and through the Interior will return Friday, and continue through the weekend for many southern communities.

A general 20-40 mm of rainfall expected along the South Coast from Friday through Sunday.
