Much Needed Rainfall in the Forecast

A frontal boundary currently positioned to our south (Figure 1) will shift northward today.  As this occurs, plentiful moisture will push into the Ohio Valley from the Gulf Coast on southerly winds.  The combination of the forcing associated with this boundary, instability,  and abundant moisture will lead to the development of showers and thunderstorms across central Kentucky and southern Indiana today through the weekend. The Hydrometeorological Prediction Center (HPC) predicts three-day rainfall totals from today through Sunday night will generally range from one half to 2 inches, with the higher rainfall totals located across south-central and eastern Kentucky (Figure 2).  Such area-wide precipitation would be extremely beneficial given the current drought conditions across Indiana (Figure 3) and Kentucky (Figure 4).
