An upper trough will remain over the Coastal mountains today and consequently the entire province will be under a westerly onshore flow. A zonal jet stream will follow this upper trough on Saturday bringing heavy snow and strong winds to the Northwest Coastal. At this time, an elongated zonal jet has formed over the northern Pacific to fetch tons of moisture. A short wave developing along the jet stream will lead the a strong system striking the BC mountains on Sunday.
