Shifting into fall
A trough of low pressure will cross the BC coast today bringing showers and breezy conditions to the south. The trough will parade across the BC Interior late Saturday spreading clouds and scattered showers to the area. Most of the province will dry out on Sunday ahead of a storm that will cause a major shift in the overall weather to a fall pattern. Rain and very strong winds will reach the BC coast and Vancouver Island Sunday night, and continuing into Monday. Some showers will sneak into the BC Interior as the Coast Mountains will keep most of the precipitation confined the coast under a southwesterly flow.
The 500 mb animation depicted above shows the upper ridge over BC breaking down resulting in showers for the BC coast and a chance of showers for the interior. An upper low will approach Vancouver Island late in the day Sunday. The upper low will persist into early next week.
