An upper ridge along the BC coast disappear
by Saturday when an upper trough rotates in from the prairies. Colder air that moved into the northern half of the province yesterday will infiltrate the southern half today. The Arctic airmass will
give very strong outflow winds through the Coast Mountains although temperatures will remain moderate near the coast. Some light precipitation over the SE Rockies today and over the Coast
Mountains tomorrow is the only precipitation noted over the next two days.
The extended forecast sees a stagnant pattern establish itself with an upper low over the northern half of the province. The only challenge will be a small low trapped over Vancouver Island. Where exactly this low ends up will dictate precipitation
type and amount for the Island and the lower mainland mountains.
