"Many people wondered how snow could fall through air with 40- and 50-degree temperatures in the Valley, well above freezing. National Weather Service meteorologists said Sunday that moisture particles were being lifted higher in the atmosphere, where it is very cold."Today, what happened was, there was a little bit of clearing in the afternoon, instability, small thunderstorms formed south of Prescott and near Cave Creek and Carefree, moved south and there was a down rush of wind and particles," meteorologist Hector Vásquez said. He explained that all moisture in clouds starts off in snowflake form, but because the moisture was so high up in the atmosphere, it stayed colder for longer and didn't melt immediately, allowing it to remain as snow at non-freezing temperatures. It would be the same as watching an ice cube melt slowly rather than immediately on a warm surface, meteorologist Austin Jamison said."
Thank you for that ice melting metaphor, because without that I don't think I would get it.
