To the same time as Invest 91 in the atlantic (the first tropcial low of this hurricane seasion in the atlantic) we are expecting quite nice yloud formations, and thunderstorms. Today please get ready to take pictures and write articles on the forum; we will maybe have some great cloud formations today, in front of a cold front. But main concentration is expected tomorrow; Friday. The wonderfull towering clouds are already expected before noon; wonderfull to be seen at about 2:00 PM in Berlin, and then In the evening thunderstorms are possible, maybe even likely!!!!! the possibility is currently forecasted between 50 and 60 %, and these forecasts might still change. But tomorrow I am writing two forecasts, and am online "to your service" in the morning, and in the afternoon from aproximently 4 to 4:40pm. Please post pictures and write about your "chase".
