Abstract: The present paper analyses the types of synoptic situations that generated obvious weather instability within Oltenia between May 25 and June 6. Weather instability is usually associated with pronounced coolings that brought to the occurring of monthly minimum values or event o absolute minimum values for May and June during the abovementioned interval. In certain years, in the same period, there occurred rain showers that generated great precipitation amounts and floods in certain parts of Oltenia, while other times, hail registered exceptional dimensions and, consequently, important material damages (June 2, 1995, Marinică, 1995, 2005). We consider this paper is extremely useful for the researchers involved in weather forecast and climatology.
