Winter Storm Warnings Issued for Northern Cascades and Blue Mountains

Winter storm warnings from 1 AM Sunday to 4 AM Monday for elevations above 3,500 ft in the Northern Cascades and Northern Blue Mountains. Accumulations of 7-15″ and 10-15″ expected in respective areas. Snow levels currently around 4,000 ft set to increase, with warnings lasting into Monday. An active weather pattern is forecast, bringing continued precipitation through the week with chances of fog during rain.

Winter storm warnings have been issued, effective from 1 AM Sunday to 4 AM Monday, for elevations exceeding 3,500 feet in the Northern Cascades and Northern Blue Mountains. Residents can anticipate significant snowfall along with challenging visibility, leading to difficult driving conditions. Predicted accumulations range between 7 to 15 inches in the Cascades and 10 to 15 inches in the Blue Mountains.

Current snow levels are roughly around 4,000 feet, slightly lower than previously forecasted levels of 4,500 feet. This small variation has resulted in notable differences in the snowfall forecast. Areas such as La Pine and Lava Butte, located near 4,000 feet, have already reported approximately 3 inches of new snow. Over night, snow levels are expected to rise to between 5,500 and 6,000 feet.

The warnings extend over the eastern slopes of the WA/OR Cascades and Northern Blue Mountains, commencing at 1 AM on Sunday and lasting through Monday morning. A brief escalation in snow levels will occur due to cold air advection aloft, linked to a shortwave trough and surface cold front moving eastward away from the Cascades on Sunday afternoon. Following this, surface high pressure will emerge, resulting in breezy to windy conditions.

By Monday afternoon, the upper trough will have shifted eastward, leading to reduced snow shower activity. Despite the presence of an upper-level ridge, several shortwaves will continue to propagate over the ridge, suggesting that widespread precipitation is still anticipated, particularly late Wednesday into Thursday.

Current forecasts indicate that while an active weather pattern prevails, the occurrence of widespread fog or low clouds is not anticipated. However, patchy fog may manifest during heavier rainfall periods as conditions develop.
