 +----------------------------------------------

A dry line is a term used by meteorologists to describe a boundary between moist and very dry air masses, but it differs from a cold front such that temperatures are often as warm or warmer behind the boundary.  These boundaries are common in places like Texas and Oklahoma, but are sometimes brought to Iowa by powerful storm systems like the one we experienced yesterday and often also spark severe weather.  The featured image is from IEM Northeast Ames sensor showing the drop in dew point with the passage of the dry line.
