...BLOWING SNOW FOR PORT HEIDEN THROUGH TUESDAY NIGHT... Blowing snow with reduced visibility is expected for the extreme southwestern portions of the Bristol Bay coast, particularly Port Heiden. Cold, Arctic air wrapping around the back side of a low in the Gulf of Alaska is expected to enhance snow showers and gusty northwesterly winds across portions of the eastern Bering Sea. These conditions will combine to produce blowing snow with visibilities dropping to as low as one half mile at times. Winds will increase during the morning hours today, which will initiate the threat for blowing snow. Northwesterly winds 25 to 35 mph can be expected near Port Heiden, with gusts to 45 mph at times. Snow shower activity, along with the threat of low visibility, should diminish through the evening hours as a warmer and drier airmass moves into the area, though gusty northwesterly winds will continue through Tuesday night.
