Analyzed are atmospheric conditions at the tornado formation in Obninsk (the Kaluga oblast) on May 23, 2013. The sets of meteorological parameters obtained from different sources including the high-altitude meteorological mast in Obninsk and giving the full pattern of conditions in the lower 300-meter atmospheric layer are used as initial data. Presented are the results of computation of some indices of convective instability using the WRF model with the high spatial resolution as applied to the conditions in Obninsk on May 23, 2013. Given is the assessment of the possibility of the advance forecasting of tornado-risk conditions based on the mentioned approach.
