Melting snow is a good sign for anyone interested in local air quality. “We are already seeing a lot of surface exposure,” explains Dr. Lyman, Executive Director of the USU Bingham Research Center. “In other words, some of the land surface in the Basin is now snow-free and the more of that we get, the more the ground will heat and keep the melt coming.” Lyman explains that another storm starting around Sunday is going to bring more warmth, delivering another gut-punch to the snow pack. “It can only hold out for so long,” he says, “and there is reason to hope that the unsettled weather will keep us from having the extremely high late-season ozone that I’ve been warning and worrying about.”
