Mountain Weather Forecast

Today, there will be isolated showers with a risk of thunderstorms over the southern interior. The intensity of these showers will be lower compared to yesterday, as the atmosphere becomes more stable. A weak upper trough will cause showers to develop along the North Coast, gradually spreading clouds and isolated showers towards the Prince George area tonight. As we move into Saturday afternoon, the upper trough will bring increased instability to the southern interior, resulting in scattered showers and thunderstorms.

The 500mb animation displayed above illustrates an upper ridge extending from Vancouver Island to the BC Peace River region during the morning hours. However, this ridge will gradually weaken throughout the day due to the approach of an upper trough from the west, as well as a weak upper low that will linger over Washington State. Consequently, mostly sunny conditions are anticipated today, encompassing the South Coast, Central Interior, and BC Peace River region, thanks to the ridge of high pressure.

During tonight, the upper trough will progress across the central interior while losing strength, eventually reaching the southern interior by late Saturday. This movement will result in atmospheric destabilization within the region.

As we advance to Sunday and Monday, the upper ridge will rebuild over the southern half of BC, leading to sunnier conditions. However, an upper trough is set to advance onto northwestern BC on Sunday, subsequently crossing northern BC on Monday. This trough's trajectory will bring scattered showers along its path.
