…LOW SNOW LEVELS WITH MULTIPLE ROUNDS OF PRECIPITATION…
.A sharp cold front will push through the region Monday night into
Tuesday morning with a cold air mass to follow through at least
Thursday. Snow levels will quickly lower from around 3000 ft during
the day Monday to around 1000-1500 ft late Monday night into the
early hours of Tuesday. Multiple waves of precipitation will move
through the region while this cold air mass is in place, bringing
multiple opportunities for low elevation snow. This will be a long
duration event, and after the initial front Monday night,
precipitation will become more showery, resulting in periods of
spotty and quick accumulations. The values reflected below indicate
totals over a 72 hour period from 10pm Monday through 10pm Thursday.
Daytime heating will result in snow levels rising to around
2000-2500 ft during the daylight hours, then lower back down during
the overnight periods. The best chances for accumulating snow down
to valley floors will be during the overnight and early morning
hours.
* WHAT…Heavy snow expected above 5000 ft through Monday morning
with accumulations of 4 to 8 inches expected. After a brief lull
in precipitation Monday afternoon, snow levels drop to all areas
Monday night into Tuesday, and remain low through Thursday.
Additional snow accumulations 10 to 15 inches are expected with 1
to 2 ft expected above 4500 ft. Winds gusting as high as 40 mph
over high and exposed terrain.
* WHERE…Southern and eastern Siskiyou County. This includes
Highways 97 and 89, Interstate 5 south of Weed, Black Butte
Summit, Snowman Summit, Dead Horse Summit, Grass Lake Summit and
Mt Shasta Ski Park Road. This also includes the communities of Mt
Shasta City, Dunsmuir, McCloud and Tennant.
* WHEN…Until 10 AM PST Thursday.
* IMPACTS…Travel may be very difficult to impossible. The
hazardous conditions could impact the Monday morning and evening
commutes. Gusty winds could bring down tree branches.
* ADDITIONAL DETAILS…Snow levels of 5000 feet today are expected
to lower to 4500 ft tonight then down to 4000 ft Monday. There
could be a period early Monday morning when precipitation
intensity brings snow levels down to Mt Shasta City, resulting in
accumulating snow along the I-5 corridor.
