Special Weather Statement

Statement as of 2:17 PM PDT on May 20, 2013

Expires 6:30 AM EDT on May 21, 2013


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

A potent cold front will sweep through southern Oregon and
northern California Tuesday afternoon and evening... 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 2500 feet by Wednesday
morning... bringing in 2 to 5 inches of snow over
all Cascade passes... Siskiyou Summit... and The Mount Shasta area.
Snow amounts of over a foot 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 Tuesday 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.

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