Special Statement  Statement as of 2:14 PM PDT on May 21, 2013

A front is moving through the area this afternoon and evening.
Widespread showers are expected... especially west of the Cascades.
Showers may contain small hail and strong winds. Very gusty winds
will continue into the evening. Behind the front... a cold showery
air mass will remain in place tonight through Wednesday. Also
temperatures will fall sharply tonight and Wednesday morning.

Snow levels are expected to drop to around 2600 feet by tonight.
Cold showers will bring 3 to 6 inches of snow to all southern
Oregon Cascade passes and 1 to 3 inches over Siskiyou Summit. Snow
amounts of 3 to 6 inches are possible on the higher portions of
bear Camp Road. State Route 45 to the Oregon caves may also see
several inches of snow. Overnight snow levels may drop briefly
down to lower passes like Sexton Summit as well. However... with
the longer days and higher sun angles... soil and Road temperatures
are quite warm and snow may melt quickly... especially below 3500
feet elevation.

Cold nighttime temperatures will bring below freezing temperatures
east of the Cascades tonight and Wednesday night. Temperatures in places
east of the Cascades may drop into the mid to lower 20s... possibly
causing unprotected exposed pipes to burst. West of the Cascades
temperatures are expected to lower in the mid 30s for many
locations tonight and around freezing in the Shasta vally.

Stay tuned to your local National Weather Service forecasts for
updates as the system progresses.

... Unseasonably cold temperatures and pass level snow expected
this week...

A potent cold front will sweep through southern Oregon and
northern California today... bringing an unseasonably cold air
mass to the area. Strong gusty winds and widespread precipitation
will accompany the front as it passes through... and temperatures
will fall sharply.

Snow levels are expected to drop to around 2800 feet by Wednesday
morning... bringing in 3 to 6 inches of snow over all Cascade
passes and 1 to 3 inches over Siskiyou Summit. Snow amounts of 3
to 6 inches are possible on the higher portions of bear Camp Road.
Snow levels may drop briefly down to lower passes like Sexton
Summit as well. However... with the longer days and higher sun
angles soil and Road temperatures are quite warm... and it will be
difficult for snow to accumulate.

Cold nighttime temperatures will bring below freezing temperatures
east of the Cascades tonight and Wednesday night. Temperatures in places
east of the Cascades may drop into the mid to lower 20s... possibly
causing unprotected exposed pipes to burst.
