From the National Weather Service, Norman Forecast Office (5:03 p.m.): Watching a complex of storms developing over central Kansas. This complex has a good chance of growing and speeding up as it moves south in the next few hours with primarily a damaging wind threat. Best guess is that this complex may move into far northern Oklahoma (Grant and Kay counties) sometime around 9 p.m. If this complex occurs, the Oklahoma City metro area could be affected some time between 11 p.m. and 1 a.m.
(Remember timing can change.)
