URGENT - WINTER WEATHER MESSAGE
National Weather Service Eureka CA
340 AM PST Tue Jan 5 2021

...Accumulating Snow Expected around Scott Mountain Summit on 
Wednesday...

.A wave of low pressure developing along an approaching front
will enhance southerly, upslope flow out of the Sacramento Valley.
This will enhance precipitation rates and localized cooling 
around northern Trinity County, keeping snow levels lower. While 
snow levels may rise above 6000 feet on Wednesday, particularly 
over southern and western portions of the Trinity Alps, enough 
snow is expected before this occurs, particularly around far 
northeast Trinity County, to have some travel impacts on Highway 3
at Scott Mountain Summit.
