Environment

Thunderstorms ignited along a frontal boundary draped over the region. The surface temperature map shows the nice thermal gradient associated with the front, with low to mid 60s in central IL and near 90 along the KY/TN border. A 500mb shortwave trough was located over the Central Plains with a weaker ripple in the flow located over western KY during the late afternoon. Mid level flow was enhanced with winds over 40 kts at 500mb. This helped sustain organized convection over our area. Precipitable water values were quite high, even by July standards, with values up to 2.3 inches! This resulted in thunderstorms being very efficient rainfall producers and thus flash flooding being an impact. Images below are from the NOAA/NWS Storm Prediction Center.
