Plow wind is an outdated rural nickname for strong and severe outflow winds from thunderstorms, especially those that "plow" the dirt into the air, as in this fine example. Such winds aren't restricted just to squall lines or multicell storms. The plow wind here, evident underneath a ragged arcus cloud, was part of a west Texas supercell's rear-flank downdraft.
