| Single- and multicell thunderstorms along convergence lines. |
| Synopsis: advection of deep unstable air from E. During the afternoon weak, moderate and isolated severe thunderstorms developed on a convergence line over northern Belgium. Over the Ardennes, some of the more intense thunderstorms were also triggered by orographic circumstances, and included even a right moving supercell near Liège. Over my area three weak thunderstorms passed within 6 hours, but with few precipitation. All pics taken at Kampenhout in local time (CET). |

towering Cumulus gave a nice crepuscular ray in the hazy sky. Compare
with the radar picture at exactly the same time.

09/05/2006 1830 NNE. Another vertical panorama stitch giving a
closer look of the threatening sky: only a few drops fell and each
minute (or two) a cloud-to-cloud strike did occur.

09/05/2006 1850 S. On the opposite side a wall cloud alike structure of this multicell, but in fact nothing more than a rain shaft with a towering Cumulus behind.
