  6. Dry Lines During the spring and early summer, forecasters in the south-central USA know to watch for the formation of a "dryline" - the narrow boundary separating hot, dry, southern Rocky Mountain air from very moist Gulf of Mexico air. The dryline's daily eastward movement, under the right conditions, can trigger severe thunderstorms and tornadoes. http://www.usatoday.com/weather/tg/wdryline/wdryline.htm
