Event narrative

Several AWOS sensors across Bristol Bay reported periods of light freezing rain near midday on November 30th, including Dillingham and King Salmon.

Wider weather episode

A low pressure system moving into Southwest Alaska from the Bering Sea, sending a layer of warm air aloft overtop sub-freezing surface temperatures. This resulted in a light mix of sleet, snow and freezing rain for a number of locations across the Kuskokwim Delta and Bristol Bay area. Accumulating ice was minimal for this event.
