Mountain Weather Forecast

An Omega blocking pattern develops over most of BC with a ridge of high pressure centred over northern BC, sandwiched between two lows; one over the Pacific Ocean, and the other over Saskatchewan. This stable weather pattern should give generally dry conditions for the majority of BC for the rest of the week. The exceptions will be along eastern facing slopes of the Rockies along the BC/Alberta border, and mountain ranges along the US/Canada border where a northeasterly upslope flow and lingering instability will produce light precipitation this week respectively.

An upper ridge building offshore will act as a block to any incoming Pacific weather systems, thus establishing the beginnings of an Omega blocking pattern for the remainder of week. This will result in fair weather skies over northern BC today followed by the rest of the province today and onwards. Weak signal of a ridge breakdown sometime over the weekend (Saturday over the south coast).
