The main focus for impacts through this forecast period is steam fog at the river valley sites of KJEF, KSUS, and KCPS. As with the last several nights, KSUS is expected to see the worst of the impacts. Any fog that develops will dissipate shortly after sunrise, with VFR flight conditions expected the rest of the day.
