Forecast Discussion for ILN NWS Office SYNOPSIS... A relative lull in thunderstorm activity is expected today before a warm front lifts back northward overnight. This will eventually result in scattered strong to severe thunderstorms on Saturday and again on Sunday, with heavy rain leading to some flooding issues. A cooldown is expected behind the cold frontal passage Sunday night, but hot and humid air quickly builds back into the Ohio Valley by the middle of the next work week.
