Dave, thanks very much for taking the time out to write that fantastic and detailed reply which I appreciate very much. Now I'm delighted I asked!.

That sounds like not only a great example of severe weather in Ireland, but quite a terrifying experience also. Not many people can say they have had a closer encounter with a tornado in this country, that makes two on this forum already, which shows just how often these events occur. Did you get any investigators ringing you after the New Year's day event , such as John Tyrrell from TORRO?. The account you wrote is amazing reading.

The sequence of events at the graveyard matches the classic severe weather structures on a storm cell. The dark wall moving toward you must have been the gust front with shelf cloud marking the leading edge of the storm cell. Behind that is the precip core where lightning would be most frequent, behind that was the rain free base where tornados can lurk. The improved visiblity after the encounter confirms that. (see image below - cell moving L to R)



I may have read on a few news websites about the car incident in Dublin so I must get back on the net and do some more research. The incredible experience you kindly shared with me has just got me even more interested in this subject than ever before!

Thanks also for the supercell and funnel info from the first account. I could imagine the adrenalin pumping as you ran for the camera!. Must have been quite a vortex whipped up by the rotation in the cell.

Thanks again Dave for the information, I will be returning to this thread again and again.  Smiley
