... Unseasonably cold temperatures and pass level snow expected
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.
Stay tuned to your local National Weather Service forecasts for
updates as the system progresses.
