A man was killed in southern Poland hit by lightning. In Paris, a birthday party in Parc Monceau was struck, injuring 11 people, eight of them children on Saturday afternoon, 28 May. Several are in a life-threatening condition. Three people were seriously hurt at a youth football match in Germany. Heavy rain caused some localized flooding as well. On 29 May to 30 May torrential rain hit south-western Germany and killed four people. Flash floods affected many businesses and homes. The worst affected region is the town of Braunsbach where floodwaters swept away two bridges as well. Dozens of homes there are at risk of collapse and must be evacuated. This investigation will focus on the event in Germany. |

3. Predictability
3.1 Data assimilation
As we recently have started to assimilate humidity observations from a few Lufthansa aircraft, this is a good case to monitor the use of this data.The plot below shows the the observation statistics for humidity observations from aircrafts for the lower part of the troposphere. The box is centred on Frankfurt to get observations from ascending and descending flights.
3.2 HRES
HRES forecasts and observations from precipitation valid 29 May 06z- 30 May 06z. The last forecast (29 May 00z) captured the region of maximum precipitation.
