Synoptic and Mesoscale conditions for August 5th...A large upper trough was anchored over the central plains the morning of August 4th with a surface reflection across southeastern Iowa. A warm front stretched from this low across northern Indiana which provided the low level focus for shower and thunderstorm development the morning of the 4th. The airmass south of this front was tropical in nature with surface dewpoints in the middle 70s and precipitable water values from 1.75 to 2.00 inches.
