when warm and cool air mix

welcome to september. the end of summer in the north is bittersweet indeed. there is nothing subtle about our seasonal transitions in the north. one day the winds are warm, pushing moist humid air up from the gulf of mexico, and the next they are cold, with dry winds pushing down from canada. for a few weeks in spring, and few weeks in autumn, there is a tug-of-war that is played out right above our fare state. it usually means rain and thunderstorms as the giant air-masses duke it out. and in both seasons rains mean mushrooms.
