WICHITA, Kan. (AP) -- The National Weather Service's office in Wichita will be offering advanced storm spotter training for the first time since it started giving basic sessions more than 50 years ago.

The Wichita Eagle (http://bit.ly/13t5jIZ) reports meteorologist Robb Lawson will present the advanced classes in Salina, Parsons and Wichita starting in early April. He says anyone who wants to take the advance training should attend a basic session first.

Lawson says the weather service has been working to make its storm spotter sessions interesting yet not so technical that they turn people off. Too much science can get boring, while too many light-hearted videos and anecdotes lead to people saying they didn't learn much.

Lawson says the basic sessions will focus on safety, while the advanced ones will focus on the science.
