Showers, but Sunny on Sunday
The next two days will be very similar in terms of weather. Showers and risk of thunderstorms are expected for southern BC in the afternoons and fair weather is expected in northern BC and Yukon. Temperatures will still be slightly below normals for this period. The weak upper ridge will finally arrive on Sunday. This will give drier and seasonal temperatures for BC. Yukon will be the opposite on Sunday. A low pressure centre is developing in central Yukon to give widespread showers on Sunday.
This 500 mb animation shows an upper ridge of high pressure over the Pacific Ocean stalling over the next two days, while a weak upper trough generates showers over southern BC. The upper ridge of high pressure will move inland on Sunday, bringing warmer temperatures and sunshine. However, the upper ridge will be short-lived. A weak upper trough and zonal pattern returns on Monday, so more showers are expected. The next Pacific system is expected to arrive Wednesday morning.
