Are the roads normally still full of snow this time of year ?
24 Feb - 10 Mar
Yosemite roads that are closed in winter and not plowed will be covered by snow. These include all of Tioga Road from just past Tuolumne Grove to the Tioga Pass entrance and the Glacier Point road past Badger Pass.
Roads that are plowed when snow falls will either be open & clear or will be in the process of being plowed. No one can predict the exact dates of snowstorms nor the elevation level where the precipitation is snow instead of rain.
Hopefully there will still be snow at Badger Pass / YosemiteSkiArea. It is possible there will be snow on the ground at lower elevations like Yosemite Valley.
