Record-cold weather followed the latest snowstorm into the Sierra, where the overnight low dropped to minus 13 degrees at South Lake Tahoe, California.
The National Weather Service said the new record low set Tuesday along the Nevada-California line smashed the previous record of minus 8 degrees for the date set in 1990.
The service forecast highs in the mid- to upper-20s at Tahoe on Wednesday before lows drop to single digits Wednesday night, then back below zero Thursday night as another winter storm system makes its way through the region.
In eastern Nevada, the service expects lows of minus 4 to minus 6 in White Pine County along the Utah line early Wednesday.
Temps are dropping and so are snow levels.

Freeze warnings and frost advisories were in effect early Tuesday in the Central Valley, the Central Coast, around Los Angeles and down through the interior of Southern California.
A cold system is expected on Wednesday but isn't expected to bring much rain or snowfall.
But the Los Angeles-area weather office says Thursday looks to be an interesting day.
California
A very cold system from the Canadian interior is predicted to move into the state from Nevada, meaning the air mass won't be modified by passage over relatively warm ocean waters.
Forecasters say snow levels around Southern California could fall as low as 1,500 feet almost anywhere, except along the coast.
