Nothing happening down here.

Yea, about 25 miles north of you here, on fairly high ground, and just a light breeze. Looking like about 3am it will start to get windy again.

Some clusters of heavy showers off the southwest coast zipping along towards us: http://www.sat24.com/Region.aspx?country=gb&sat=ir&type=loop

96.3kmph gust recorded at Mace head already.

Sounds like that wind was the outflow from the cloud dropping that hail. Can see some pink flecks in that shower on the radar that probably got you. Plenty of those heavy/thundery showers expected to roll in tonight.

I wondered that but the shower cloud was to my SE & the wind definitely came from WSW. I was in the south of the UK during the famous "hurricane" so I have experienced high winds - I watched 6 in diameter conifers snapping like matches. Tonight's wind episode was almost explosive. I did wonder if it was a "mini tornado" but the wind was not circular.

Can someone describe/explain what a bow echo looks like on the radar ?

it might be a small country but it makes the world of difference which side of it you live on........light to moderate rain today and breezy top gust was about 50kmh ......i bet people in the west and north have a whole other story to tell......im in the sunny ..na ...shelthered south east:)

Look at the cold front passing over the UK at the moment, see the snake like features near the leading edge? http://www.raintoday.co.uk/
Basically they are curved like a bow getting drawn back.

Wind is beginning to make some noise here. Has become very blustery over the last 15 mins. The trees about 100 metres away are screaming! Feels milder than earlier though.

Bow echo would only apply to a long, continuous squall line feature that shows a bulge towards the direction of movement, in other words, a bow shape about 50-100 miles long usually. The activity currently on radar in western Ireland is more isolated convection, it looks like somebody opened up a hornet's nest somewhere.

Bow echo features can produce tornados but are more likely to be associated with damaging straight-line winds. A tornado is more likely from isolated thunderstorm cells ahead of the squall line feature. The kind of tornado that can accompany these cold weather low-topped convective clouds is really more of a waterspout feature that may form near land or over a lake, and then track for some distance across land before dissipating.

They are all destructive to some extent, but the big tornados that form in the central U.S. and occasionally in parts of western Europe are more likely to form on fast-moving cells that are a few miles south of a well-defined front, or along such a front in some cases. If a tornado is going to form near a bow echo, it's usually somewhere near the southwest end of the bow, or the leading edge of it.

This is a bit sketchy, but if you see a radar echo that looks like this, it's a bow echo (and especially if it has high intensity levels too, if weaker, it would be more of a gust front sort of thing).

What causes a bow echo? Usually it's some condition along the path of a cold front that causes one part of it to accelerate, perhaps it meets with less topographic resistance for a while, or clouds along it reach higher altitudes and are pushed along faster by stronger winds. They obviously have a sort of self-correcting mechanism because after some time, if the bow breaks away from the line, the front is likely to re-form behind the break, and the break-away cells may then either go tornadic or simply dissipate as they stop lifting.

Lightning in those showers swinging up from the SW

Constant wind noise now as I lay in bed. Intermittant loud gusts. Since 0.00 it's really picking up.

All quiet here so far.

irish1967

Constant wind noise is so cool. Long may it last. Well at least until I have to go out at 8am.

howlinwolf

will the east see some of this storm in the early hours or will it track north towards scotland?

Deep Easterly

Well that was great! Flat calm here now and stopped hailing. Like nothing happened!!! Maybe I only imagined it.....:D

IMBACKLATER

very windy outside, howling and roaring, not surprising being a mile from the coast

Looking at the radar/sat loop Im sure youll see more as the night/morning goes on.

Yep, hopefully, although they seem very much hit and miss jobs at the moment. As I type a very very severe downpour of hail. Jesus christ this is mad1!!

Edit. Stopped again, but that was weird. No wind. wait, now there is.

West and northwest will be getting the strong winds, its tracking towards Scotland, yes. East coast and Irish Sea will be windy in the morning though.

Other than that keep an eye on those showers on the radar to see if any head your way as they could bring you hail/thunder/downburts when they pass.

RoisinD

Winds regularly gusting to around 100kmph. Some nasty hail showers rolling in as well and it looks like there are many more to come.

Nasty looking shower heading for Listowel area on the radar.
