An upper level low centered over parts of southern Missouri will slowly drop southeastward into Alabama by Sunday. In return, persistent bands of light-moderate showers will continue on its northwestward to southeastward track across the region. There will likely be some breaks in shower activity from time to time this weekend, especially across the Bluegrass region where chances will remain lower than parts of southern/western KY. Areal rainfall totals of 2-3 inches are expected from late tonight through Sunday, as small creeks, streams will rise as larger rivers are anticipated to reach minor flood stages. The slow moving low pressure system will continue to push through the state by Sunday afternoon, as rain associated with the front should exit the region by Sunday night with low overnight temperatures in the low 50’s statewide.
