Forecasters at the National Weather Service's Storm Prediction Center in Norman placed western and central Oklahoma under an enhanced-risk Saturday afternoon outlook, with very large hail, damaging straight-line winds and a small number of tornadoes possible from the late afternoon into the early evening. The threat extends in a weaker form across parts of Texas, Kansas, the central High Plains and the Gulf Coast states, where slower-moving cells could produce flash flooding through Sunday morning.
Saturday's outlook came as Mississippi continued to inventory the damage from the May 6 tornado outbreak, which the National Weather Service in Jackson now confirms included fourteen tornadoes touching down across the southern half of the state. Approximately five hundred homes were damaged or destroyed across Lincoln, Lamar, Wilkinson, Lawrence and Franklin counties, and seventeen people were injured, the most serious of them a four-month-old infant in Bogue Chitto.
Governor Tate Reeves declared a state of emergency on Thursday and on Saturday morning toured the trailer-park community at Bogue Chitto, where a violent tornado flattened all but one of twenty-four mobile homes. The governor said he had asked the White House for a federal disaster declaration that would unlock direct assistance to homeowners through the Federal Emergency Management Agency, although he conceded that the agency's ongoing reorganisation under President Donald Trump had introduced uncertainty over response times.
The Mississippi Emergency Management Agency said on Saturday that it had distributed about 11,000 meals and 22,000 bottles of water through three staging sites in Lincoln County. The Salvation Army has set up a mobile kitchen at the Brookhaven civic centre, and a network of churches across the diocese of Jackson is housing displaced families on a rolling basis. No fatalities were reported from any of the Wednesday-night tornadoes.
The wider weather pattern is being driven by an unusually persistent upper-level trough that has stalled across the central Plains and is unlikely to break down before Tuesday. National Weather Service offices in Norman, Wichita, Amarillo and Tulsa have positioned additional radar staff and storm-spotter coordinators for the weekend, and FEMA Region 6 has pre-positioned ten generator-equipped command vehicles in Oklahoma City.
