TONIGHT AND SUNDAY: THERE WILL BE SEVERAL CHANCES FOR SEVERE STORMS THROUGH THE EVENING ACROSS EASTERN NEBRASKA AND SOUTHWEST IOWA. STORMS DEVELOPING ALONG THE MISSOURI RIVER AT LATE AFTERNOON COULD PRODUCE HAIL OR DAMAGING WINDS IN WEST CENTRAL IOWA. MORE STORMS IN NORTHEAST KANSAS WILL TRACK INTO SOUTHEAST NEBRASKA AND SOUTHWEST IOWA AS WELL…AND COULD ALSO PRODUCE LARGE HAIL OR DAMAGING WINDS. THERE IS ALSO A SMALL CHANCE FOR AN ISOLATED TORNADO AS LOW LEVEL WIND SHEAR IS MAXIMIZED IN SOUTHEAST NEBRASKA.

MORE THUNDERSTORMS DEVELOPING IN SOUTH CENTRAL KANSAS AND FARTHER SOUTH ARE EXPECTED TO RACE NORTHEAST DURING THE EVENING. THESE STORMS COULD MOVE INTO SOUTHEAST NEBRASKA AND SOUTHWEST IOWA AT MID TO LATE EVENING BRINGING A DAMAGING WIND THREAT TO THOSE AREAS. AN INCREASING LOW LEVEL JET WILL ALSO PROVIDE NECESSARY SHEAR TO KEEP A SMALL TORNADO RISK IN THE FORECAST.
