Powder Alert -PNW/BC- Longer Range Pattern Looks Good

Share

Synopsis:

We are a non-AI-generated forecast

Low pressure over British Columbia slowly moves south over Vancouver Island from Tuesday PM to Wednesday morning. Widespread 5-11 inches of snow are likely from western BC and a wide area of the western Cascade Range from Washington to Oregon. Temperatures plummet below seasonal norms by Wednesday morning, driving snow levels below 3500 feet. This low is a slow mover and could bring some surprise upside to the Cascades (Outside chance of 11-17 inches in isolated locations).

Northern Idaho and Montana, including interior regions of BC, will also grab decent freshies with this storm.

Extended Forecast! November comes in Deep?

Below: 24-hour snow totals on a moving map from 11/1 to 11/3. You can see a trend for deeper pockets of snow from Idaho into most of the northern Rockies, peaking over most of Colorado by 11/2-11/3 (Date and time in the upper right corner). This could be a good storm!

Below: Low pressure in the extended forecast overspreading the Rockies in the first few days of November. This system currently looks relatively strong.
