Narrative:

Snowplow on runway 10-28 crossed runway 4-22 after acknowledging to hold short. Because of visibility 1/4 mi or less, the plow was not in sight from the tower. During the time the plow was told to hold and was seen on the other side of runway 4, 1 atx departed and 1 landed on runway 4. Ground and local were combined because of staffing.
