... Much cooler weather today snow levels lowering to pass level tonight...
There will be a drastic change in temperatures today as a cold low pressure system moves over northwest Oregon. Many locations will see temperatures 15 to 20 degrees cooler than those experienced Monday.
Snow levels will start out high... above 8000 feet this morning... then lower to 4000 feet this evening... and down to 3000 feet by Wednesday morning. Snow accumulations are expected to remain below advisory conditions with 2 to 4 inches expected between 3000 and 6000 feet Tuesday night through Wednesday. Higher snow amounts... 6 to 9 inches are likely above 6000 feet.
Showers at lower elevations may include small hail this afternoon... potentially resulting in extra slick roadways. There may also be a few thunderstorms this afternoon and evening.
Drivers should use extra caution... especially while driving over the Cascade passes or encountering small hail on the roads. Slow down and leave plenty of room between cars.
Hikers and climbers venturing into the mountains will want to be prepared for a quick change to cold and wet weather today... especially following a deceptively warm and sunny Monday. From 3000 feet and up... be prepared for accumulating snow starting this evening and continuing through at least Wednesday night.
