Winter Storm Hits Washington Cascades Tonight Thu Tuesday

If you thought spring was here already, you would be wrong. A large storm that buried parts of northern California with snow is now hitting Washington State starting tonight. The storm is forecast to bring 8-18 inches of snow to the Washington State Cascade mountains and a possible 40+ mph winds. That combination of snow and wind would make for treacherous driving conditions throughout the Washington State passes over the next couple of days.
