Thunderstorm Outlook: Fri/Sat 16-17 September

After a very stormy week of 5-10 September, when an upper cold pool over the warm Mediterranean caused numerous storms and resulting floodings (and tornadoes, and sprites!), the past week proved more quiescent, weatherwise. Today cold air is again advected in the middle layers of the troposphere towards Spain, whereas warmer air and humidity converges in the lower layers. This brings life to new storms. In this time of year, the seas are relatively warm and function as a supply of energy to nightly storms, especially at the coasts of the Mediterranean. These days it will be mainly the Spanish east coast at night, later in the weekend the focus shifts to Italy.
