This Tornado Warning has ended but a Severe Thunderstorm Warning remains in effect for McCurtain County on the OK side of the Red River and for Bowie and Red River Counties on the Texas side of the Red River until 6:15 p.m.
I've linked a Severe Weather Statement concerning this from the Shreveport office of the NWS. It describes the storms current location and path. It also details some of the early damage reports from the Idabel area.
