Meteorologists from National Weather Services offices will survey damage paths on Saturday, but initial reports from the Storm Prediction Center indicate more than two dozen tornadoes impacted states from Arkansas to Kentucky.

President Joe Biden tweeted Saturday that he was briefed on the situation and pledged the affected states would "have what they need as the search for survivors and damage assessments continue."
