Winter Storm in City and Borough of Wrangell, Alaska

Light snow fell during the MLK long weekend across Wrangell with heaviest rates falling on the 15th between 10am and 10pm. A trained spotter measured 14 inches storm total by late evening and others on social media confirmed that amount the next day.

Over an extended long weekend event, a prefrontal trough followed by a stronger main system with attached moisture plume, delivered first a wave of dry powdery snow with very high snow rations (40:1 to 50:1 in many places). The next wave/front of snow was wetter and difficult to shovel, with some places seeing a period of freezing drizzle in between the two waves. As the 2nd front tracked southward on the 16th, bringing snow to those areas and extending the duration of the event.
