NW Open Snow Headlines
High pressure weakens, lows move in
Active weather pattern unfolds
NW Open Snow Inside Story
Our recent dry pattern is ending. The pattern was caused by a persistent high-pressure area, which now is changing, allowing a low pressure to move in. The snowless weather pattern of the last week will end with a bang, as the gates open to an unsettled weather pattern. The transition will be slow so don’t expect any significant snow until later Tuesday and Wednesday – but we'll see a little later today.
Although the models show several storms lined up from Wednesday through Sunday, the timing has been variable. The snow level will be between 2500 – 4000ft, possibly 5000 ft on Saturday for a short time (weak atmospheric river ). Each weather system in the series has a warm sector (SL 3000-5000ft) followed by a cold sector (SL 2500-3500ft), so there will be some low elevation rainfall, from time to time. But also expect some low elevation snowfall. Total snowfall from Wednesday – Sunday above 4500ft will be 10” - 20” ft. (below 4500ft: 2-10").
Whistler will benefit the most, as the greatest cold and accumulations will be north and their elevations are generally a tad higher on the upper mountain.
In the extended forecast, beyond next weekend, the models continue a series of storms headed our way – so the pattern is looking good for additional snowfall.
