Very bored tonight so was looking through some images which I thought I would share. This was some of the excellent convection on Aug 11th 2008 about 30 min's before a good thunderstorm broke out.

This a huge cumulonimbus with rock soild anvil indicating serious updraught strength. Usually the anvil is fuzzy indicating weak updraught winds but this guy was like a building. Taken from Coleraine Road looking E.

Same huge cell from the country. The base was so low that the horizon and cell blended in together. A good candidate for a funnel or better. It later developed a cluster of nice white mammatus on this side of the anvil.

From a country location looking W at heavy showers of rain and hail with cool dark scud clouds near the outflow

Storm clouds gathering in the SW near Slieve Gallion and becoming organized with heavy showers below.

Very nice cumulus congestus with updraught tower highly sheared to the R (N). Nice lowering to. Look how dark the sky is over the mountains.

Looking W over the Sperrins. I didn't know at the time but that darkness was an approaching gust front with huge shelf cloud many miles away which would produce a good t-storm and flooding.

Pity the weather is so boring at the min. I have my eye on Mon or Tues for possible t-storms or at least good convection.

Nice images, especially the last two. 

Those don't look like a summer photos...  Grin
