June 10th, 2004 Chase highlights, Heffingen (Luxemburg)
On June 10th, the next day after our previous succesful chase, conditions were favourable again further south in Luxemburg. We intercepted a large multicellular storm complex coming from France and heading northeast, with a constant inflow of new cells at its southern tip. It was quite a rush to stay out of its raincore from the anvil but the road was perfect: first south and later a little southeast, and finally we reached a town called Heffingen, south of Diekirch (LUX) where we had a clear view at the main storm's most southern edge, after driving through a mini-rain core in front of the main system:
As if a show was set up especially for us: the storm behaved exactly what I was hoping for: a new segment entered the system. What started out as a small cigar-like shelf, turned into a monster shelf in less than 10 minutes, with parts turning over somewhat greenish before battering us with rain and hail up to 1.5cm (0.6 inch). We couldn't escape this baby and went south as soon the rain and hail set in, towards the highway we needed anyhow to go back home after this two day chase. Before we went west again, we followed the system a little further east on highway E44, and made our last stop on a parking lot at exit 3, Trier (Germany) of highway E44. There we found the largest hail: almost 2cm (0.8 inch) in diameter, but as you can see by the dents melted in from the grass (probably already 20 minutes or so): it originally probably had a diameter of a 2 euro coin.
Below are some slide scans of the same events. Colours are different due to different glass in lenses, provia slide film instead of digital etc etc. And besides that, these images too needed a lot of enhancement. I'm not very familiar yet with my new 12-24mm sigma. Getting the right exposure if things go this fast is not easy.
