(12:30PM - 5/16/20) The same storm system that will bring the chance for severe t'storms to the state on Sunday, will also bring heavy rain and flood potential to portions of the state as well from today through Monday morning.
Multiples rounds of rain and t'storms will move across the state, from this afternoon through Monday morning. This activity will be widespread, with much of the state seeing multiple rounds of activity during this period. Given there will be high atmospheric moisture content for efficient rainfall, repeated rounds of activity, and training potential, a low flood potential will exist for a good portion of the state. Additionally, for areas across portions of Northeast Illinois that were recently affected by heavy rain and flooding a few days ago, moderate flood potential will exist across this area given saturated soils and some flooding still ongoing. Final event rainfall totals for this period will range from 1.00-3.00" across the main corridor across the state, with localized higher amounts possible. Outside of this main corridor, rainfall amounts of 0.25-1.25" will be more common.
Below is the flood forecast for this event.
