Don’t put away your skis yet. A light, late-spring storm is moving into the Sierra, freshening the slopes and keeping the Tahoe snowpack chilled. Snow flurries are in the forecast today with the storm fully developing Tuesday and dropping one to four inches as low as 6,500 feet. “The cold front associated with the low pressure system will drop south toward Nevada on Tuesday,” said Evan LaGuardia, a meteorologist with the National Weather Service office in Reno. “It’s not as strong as what we saw a couple weeks ago but it will prevent the snow from melting.”
