Lightening lit up the skies over Offaly on Sunday night as a number of thunderstorms hit the county. 

At one stage, at least three thunderstorms were visible with one close to Birr, one over Derrinlough and another in the direction of Cloghan.  Our video shows a series of lightening flashes over the wind farm at Derrinlough.
