The first batch of severe weather in this year's tornado season officially hit Oklahoma and Arkansas on Wednesday, with one twister captured during a live TV weather report. That tornado, which hit as KFOR meteorologist Mike Morgan and helicopter pilot Jon Welsh were on the air, swept through the Oklahoma City suburb of Moore, caused electrical explosions and other destruction on screen. Seven people were injured and significant damage was done to homes and business, with the roof of Southgate Elementary school ripped off. Moore is the suburb where 24 people died in a top-of-the-scale EF5 tornado in 2013. Scroll down for videos .

Meteorologist Jeff Hood in Little Rock said a weak waterspout tornado briefly touched down in Bull Shoals Lake in Marion County in northwest Arkansas on Tuesday night. He said it will likely be classified an EF0 — the weakest tornado with wind speeds of 65 to 85 mph. A waterspout forms over water. The tornado never made it onto land, and there were no reports of damage. Before this week, only about two dozen twisters had been recorded this year during a period when about 120 are typical. The last time the U.S. had no twisters in March was nearly 50 years ago, according to figures from the Storm Prediction Center in Norman, Oklahoma.
