Extended periods of snowstorm activity

Dan is getting annoyed with the inability of Boston meteorologists to speak English:

... Boston meteorologists need to lighten up and give a straight forecast. The forecast last night called tonight's anticipated "snowstorm" as one that will be plowable.

Plowable?

Geez. What's the alternative? That New England shuts down for four days because the plows can't get out?

Plowable.
