Special Weather Statement  Statement as of 3:23 am PDT on May 21, 2013

... 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.
