What happened

The episode as NWS OTX wrote it up.

Over a two day period, light to moderate snow consistently fell over the Central Panhandle Mountains of Idaho. During the first 24 hours, snow was of the heavy wet consistency, attributed to a deep subtropical moisture fetch aimed into the region. A cold front moved through on the 24th and snow processes became more convective and orographically driven. Given the subtropical moisture tap in place, snow mainly fell above 5000 feet until the morning of the 24th when snow levels lowered near 4000 feet. Over the two-day period, snow amounts measured at area ski resorts ranged from 18 to 21 inches.
