A classic fall pattern has tightened its grip B.C. to close out the week, set to continue through the Thanksgiving weekend. That will mean rain, and a lot of it, as multiple fronts pass through to bring up to 75 mm for the Lower Mainland and some 10-30 mm for parts of Vancouver Island by Sunday, along with a few dashes of alpine snow, and blustery winds along the coasts. Details and timing, below.
- Rain through Sunday, 50-75 mm expected for Lower Mainland, 10-30 mm for southern Vancouver Island
- High-elevation snow Saturday night
- Sunday wind gusts reaching 70-80 km/h
THE WEEKEND: RAIN-FILLED THANKSGIVING WEEKEND, HIGH-ELEVATION SNOW
The rain looks to continue steadily overnight through Saturday morning, gradually tapering off to showers through the evening. There is, however, a chance that light rain will continue in the Interior through the overnight.
There's also some risk of late afternoon thunderstorms for the coasts and Lower Mainland, with any that do spark up likely to feature small hail, strong winds, and heavy local rainfall.
In all, parts of western Vancouver Island and upper elevation mainland coastal areas look to get more than 100 mm by the time it finally clears out Sunday morning.
Sunday will be cooler and mostly dry, but that will be a short-lived break, with another system pushing in along the coast Sunday evening, continuing into Monday.
Winds will intensify Sunday afternoon for the North Coast, with gusts reaching 70-80 km/h. South Coast may see wind gusts up to 60 km/h in the overnight.
As for the snow, an overnight shot of alpine flakes will linger into Sunday morning, easing off in the afternoon mostly but with more possible into Monday. In all, freezing levels will be as low as 1,000 m over the weekend.
Rain showers and alpine snow Sunday, and becoming more widespread and heavier into pre-dawn Monday.
Beyond the weekend, cooler and unsettled weather is expected to continue into the middle of next week. However, forecasters are watching the potential for a period of warmer and drier weather during the second half of next week.
