Not that gob****e again. Every day is a warning day for him. Pure clickbait.

He's a cockwomble and I've called him out again on his page. In other news I'm gearing up for the night myself so hopefully it's lively.

I'm a little surprised at the mention of hail as the freezing level will be at 3.0-3.5 km and the CAPE profile fairly skinny. Maybe shear and a bit more forcing from the upper trough will help.

Lots of altocumulus visible here in Arklow at the moment

Storm 10

Few heavy showers off West Coast and a spark to the South

Mr. Jetstream on the latest UK Met video forecast mentioned the possibility of hail as well for the UK with these showers.

Loads of good quality live stream cameras along the South Coast of the UK to check out tomorrow for storms

Latest 'significant' weather offering from the ECMWF for midnight tomorrow night:



Pretty much on track with the increased chance of a little something for the NW region as well (pink = thunderstorm possibility/dark pink = severe thunderstorm)

Bye Gorey.

Don't worry Gonzo. Cathal Nolan has Meath in his red zone. That's the greatest reassurance anyone could have

Sky is spectacular here in north Dublin particularly looking east. Charred up and not dissimilar to what you'd see in the US mid west desert regions this time of year.

Unusual to see here and screaming instability to come :cool:

It's just indicative. Chill. :cool:

The sky over Dublin 8 is amazing, can you guys tell me what kind of clouds these are? I don’t remember seeing a sky like this before.

Altocumulus. Sky is class in Wexford as well

Interesting....

In meteorology, altocumulus castellanus (ACCAS) is a cloud type named for its tower-like projections that billow upwards from the base of the cloud. The base of the cloud can form as low as 2,000 metres (6,500 feet), or as high as 6,000 metres (20,000 feet). They are very similar to cumulus congestus clouds, but at a higher level and with the cloud heaps joined at the base.

Castellanus clouds are evidence of mid-atmospheric instability and a high mid-altitude lapse rate.[1] They may be a harbinger of heavy showers and thunderstorms and, if surface-based convection can connect to the mid-tropospheric unstable layer, continued development of Castellanus clouds can produce cumulonimbus clouds.

Great cloud scape this evening, looks like on the continent.

Popcorn clouds. Seeing them in Dublin 16 too.

Models dialing in now, some differences in intensity and timing,WRF way out in front showing the highest Dp's and showing the highest rainfall . One common trend I think is the chance of 1 or multiple severe storms moving into or along the SE and up along the E early Fri morning. Prime location for a MCS perhaps ?
