Precautionary/preparedness actions...

A freeze warning means sub-freezing temperatures are imminent or
highly likely. These conditions will kill crops and other
sensitive vegetation.

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 46 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 Valley.

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