Tonight, we anticipate cloudy conditions coupled with scattered showers, especially as a low-pressure system continues to influence our local weather. Cooler than normal temperatures will persist, with some areas along the Cascade Range seeing snow levels drop to around 3500-4500 feet. There is a chance of brief thunderstorms for northern portions of the forecast area this afternoon, though a stable layer of warmer air aloft should limit their intensity.
For those planning travel over the Cascade Passes, we caution that snow-covered roads are possible at elevations above 4000 feet, where a Winter Weather Advisory remains in effect. Total snowfall could range from 4 to 8 inches, with higher amounts near Mt. Hood. However, the higher May sun angle will help melt some of this snow quickly today…
