A cold low pressure system will begin spreading light rain across
southwest Washington and northwest Oregon late tonight into Tuesday
morning. There will be a drastic change in temperatures Tuesday...
as many locations will see temperatures 20 degrees cooler than those
Snow levels will start out high... above 8000 feet Monday evening...
then lower below 4000 feet by late Tuesday evening. 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 Tuesday afternoon
through Wednesday... potentially resulting in extra slick roadways.
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 Tuesday...
especially following a deceptively warm and sunny Monday. From 3000
feet and up... be prepared for accumulating snow starting later
Tuesday and continuing through at least Wednesday night.
