Thunderstorm Outlook: Wed 27 July

A particularly strong thunderstorm event is expected near the thermal low over northern France this afternoon into tonight. Supercells may be able to develop as the vertical windshear and veering of the winds with height support storm rotation. Large hail and even tornadoes will be possible. These cells may merge into a line of storms with a primary risk of gusts, and this MCS during the night offers a good possibility to generate sprites. More isolated convection is likely over central and southern France. See for a thorough discussion

It is 19:20 local time and storms have started to grow in southwestern France. It may eventually grow into a mesoscale convective system... hopefully also bringing good lightning activity in Toulouse where I live. The northern France area is still free of storms, but I will not exclude that they do develop tonight. Good luck to Agnes & Olivier tonight!
