  "definition": "TROugh of Warm Air ALoft. Typically used during winter weather, it is a \"tongue\" of relatively warm/moist air aloft that wraps around to the\nnorth and west of a mature cyclone. It is best analyzed between 750-550 milibars using equivalent potential temperature (theta-e).\n\nAreas of intense lift and frontogenesis are commonly associated with TROWALs, hence they are favored regions for heavy and/or prolonged\nprecipitation. During a winter storm, the heaviest snowfall amounts frequently occur along and north of the TROWAL axis.",
