Thunderstorm Outlook: Thu 28 July

Was last night enervating with a large Mesoscale Convective System (MCS) moving from central France into western Germany, the following night may even surpass this - the Atlantic cold front pushes into the unstable airmass over France, and strong thunderstorms are expected to form in the 200 km wide zone ahead of it. The initially isolated storms in the afternoon are going to expand and merge into a long squall line or a number of MCS'es over a large portion of France as the night falls, providing a classic setup for a major sprite night. However, a good functioning of the camera systems is crucial.
After this night, cooler air will invade the observation area and high pressure will build on the Atlantic, keeping stormy conditions away for quite some time, except perhaps far over northern Italy.
