Love seeing a good timelapse, really shows the force of the weather.

Lived over there for 2 years. Was lucky enough to witness the big one in 2011. Astonishing to see an 8 mile high wall of dust coming your way! Darkness follows pretty quickly!

The dust creates huge amounts of lighting. The thunder is a constant rumble at times with no discernable gap between one clap and the next.

I wonder will Sat see some Lightning activity ( possibly the South of the country ?) Forecast to be heavy and persistent for a time on Sat morning and to clear Northwards.

The BBC forecast on news 24 just now with Darren Brett had that system on Friday night and Saturday very thundery and he mentioned thunder and lightning in in quite a few times moving up through Wales and Ireland

Can confirm that. Flash of lightning with near immediate thunder here in Dundalk.

There was a long tumble here in North Wicklow at around 4.

There is a big thunderstorm over nice, corsica and Sardines islands. It is moving towards Rome where I am these days. It looks like plenty of natural fireworks tonight.

Day 1 Convective Outlook
VALID 06:00 UTC Fri 14 Oct 2016 - 05:59 UTC Sat 15 Oct 2016

ISSUED 07:52 UTC Fri 14 Oct 2016

ISSUED BY: Dan

Scattered showers, some thundery, associated with a shortwave will continue to migrate NW-wards from the northern Irish Sea towards the Hebrides during Friday. Reasonably steep mid-level lapse rates and low CAPE suggests some sporadic lightning will continue to be possible, especially over water where warm SSTs will help develop deep convection.

Rain already into SW Ireland will slowly slide NE-wards with time during Friday and Friday night, perhaps with some sporadic embedded lightning. The post-frontal environment is characterised by much steeper lapse rates, and so the risk of lightning (albeit still sub-SLGT) increases with showers behind the cold front overnight, especially over seas. Small hail and gusty winds will be the main hazards.
