Nasty looking sky heading into West Dublin now

Sunrise lit anvil this morning - Low Res phone picture.

Thunder/lightning to the north west of Castlebar now.

A cell just off howth too , fecking typical , was out there on Monday hoping to catch something!!

Torrential hail shower reported in Celbridge from a developing cell that is only now beginning to appear on radar. Will probably hit Dublin city shortly - there may be sparks by then

Iancar29

My view towards the Airport awhile ago , saw a very faint flash of lightning and a distant roll of thunder

Massive hail shower at Punchestown Races today about 2pm accompanied by one flash of lightning and loud thunder.

Some potential for some pulse type thunderstorms late tomorrow afternoon in the North Midlands.

06z WRF showing a convective band heading NE


Some few hundred joules of cape and some decent instability should build if morning frontal mess clears quickly enough.


With the total lack of both low and mid level shear, I don't expect anything severe , but will hope the area of wind convergence will help a few active storms kick off.


06z NMM a little less appealing and has the ppn a bit further north.. I will hopefully be out if the risk is more in line with the WRF :cool:

Yep. Midlands and eastern parts probably looking most likely.

A wet start to Sunday in many parts of Ulster and Leinster but brighter, showery conditions elsewhere will soon replace the rain. However, showers will become heavy at times by afternoon, with an increasing risk of thunderstorms in many places through the afternoon and evening.

Afternoon looking good

Some good strong sunshine here in the west, some nice convection kicking off.

FWVT

Some potent lift along a convergence line through the east later this evening

Would the lack of solar heating at that time mean that there would be a much lesser chance of anything interesting building, with the sun having set and all by then?

Nice dark ridge of cloud heading north west of athlone. Not sure if there was anything thundery in it, but I'd say it was very WET!

There will still be plenty of lift through convergence to offset any diminishing diabatic heating at that time. Showers so far have been sprouting up at will, without any cap present. That convergence line later should lead to a more organised setup, though it still remains to be seen how much lightning it will produce (if any).

FWVT

ECMWF has decent CAPE this afternoon.

Looks like first couple of strikes in Monaghan.

Oneiric 3

First few strikes showing up through the mid-west into midlands.

FWVT

Nice development now, as shown by the cyan and red areas.

3 shots from my short chase yesterday near navan and then the Hill of Tara.

Maturing Cb , this tried to get a wall cloud going so bad , was nice to watch!


This cell went by right over head at the hill of Tara , perfect viewing spot may i add! Really thought this one would let out a bolt but sure probably best it didnt because i was on the highest point in the vicinity ! lol


On the way back i just had to grab a shot at this nice field rapeseed.


I'd give yesterday a 5/10

Potential for significant storm outbreak across France today.

The best radar for France that i've come across is here
http://www.infoclimat.fr/cartes-meteo-temps-reel-images-satellites-infrarouge-visible-haute-resolution.html?i=radar

Also this site is good for convective forecasts and lightning maps (although the lightning data just comes from blitzortung.org)
