A strip of snow left down the center of the roof of a person's vehicle. Either because they are too short to reach it, or just too damn lazy. Resembles the Mo~hawk hairstyle.
There was so much snow on his car that George gave up clearing it off and he left a big old snow hawk.

The sculpted ridge of central snow left on the roof of a vehicle by someone either too lazy or too short to brush it all off.
I was cruising down the highway behind a Tahoe sporting this ginormous snowhawk when the Tahoe's driver hit a pothole. Like an icy combover on a guy in a convertible, the damned snowhawk grabbed air, flipped back towards me, and I was sure that was going to be the last thing my Prius and I ever saw.

When you are trying to clean your car off during or after a snowstorm but you and your ice scraper can't reach the top middle of the truck it creates a Mohawk-like design of snow on the vehicle.
Hey man, tough time reaching the top of your truck? Ya got a snowhawk there.
