Mount Charleston saw a rare may snowfall on Tuesday, as lightning flashed and thunderstorms pelted parts of the Las Vegas Valley. The National Weather Service said it will not have a total measurement for Tuesday’s snowfall until Wednesday morning. Over the last 30 years, more than 5 inches of snow has accumulated on Mount Charleston just six times during the month of May, meteorologist Ashley Wolf said. “We might get close to that,” Wolf said Tuesday.
Mount Charleston's record for snow in May was 10 inches, which all fell on May 7, 1986, meteorologist Chelsea Kryston said.

The snowfall record for May 1 is 3 inches, measured in 1983, according to Kryston.
