Heavy Snow — Lewiston Area, Idaho

2012-01-18 · Lewiston Area, Idaho

Wider weather episode

Cold air already in place met up with a warm, moist Pacific air mass across the central to northern Idaho Panhandle. This warm front slowly progressed northward across the Idaho Panhandle with heavy snowfall over much of the region. The warm front stalled as it moved into the northern Coeur d'Alene Area and northern Central Panhandle Mountains during the late afternoon and evening hours of the eighteenth. This system weakened during the nighttime hours on the eighteenth into the nineteenth of January as drier air at mid-levels began to infiltrate in. Snow shower activity with a mix of some freezing rain/drizzle continued over the Coeur d'Alene Area and northern Central Panhandle Mountains through the early morning hours as this system wound down.
