Convective/Thunderstorm Discussion : Spring/Summer 2017

How do you interpret a skew-t diagram properly? I always have trouble understanding how to work out what level convection begins, what the level of free convection is, and what the cloud top height might be?

So how do you interpret these charts to determine if a storm  is possible??

Can hear thunder here near Tralee.

Edit: Lots of thunder and lightning now in Tralee Bay

Plenty of heat here, still 18.7C

Just hearing a few claps of thunder in Listowel. Its also extremely heavy here! I think ill move away from under the skylight for a while!

My mate sent me a video from tralee, lightning is very frequent

MidMan25

Sat on a beach in the Maherees looking back towards Tralee Bay, great view of the cell as it passed over!

Interesting sky, seems to be all high elevated thunder.

Took a pic just 20mins ago looking NW





Got a fright there! The heavens just opened up, haven't heard rain like that in a long time, Rain Rate 44.6mm / hr

Edit: Rain stopped fairly quickly, I guess that is what Met Eireann were referring to as sharp showers in their forecast.

Sure, you are right next door to all the activity happening now! If I were you, I'd be out in my garden looking to the west

Lightning activity seems to be very sporadic

How familiar is that activity? You know what's going to happen...
Storms fire well off shore to the W / NW as the trough initially engages the plume - activity tracks off NE towards far west Scotland.... Nothing else fires further east.
Large shield of cloud and muck tracks up over Ireland and gives either a few and zero sparks. Just disappointment...
Tomorrow then has max temps suppressed due to more extensive cloud than you would want with such a warm airmass. further disappointment...
Meanwhile, across the water the temperatures soar.... the streets melt.... the CAPE goes through the roof.... the lifted index through the floor.... then BOOM! 40,000ft CB's with overshooting tops, MCS (with possible embedded supercell), prolific lightning, and all this continuing well into the evening and overnight as it tracks NE.. Everyone gets to see the light show - nobody misses out. Unlike here!!!

Seems to have come off exactly the way I feared. That is the thunderstorm distribution and also the concerns about cloud amounts this morning and it's potential to ruin temperatures today.

Thunder in Tuam.

Rumble of thunder in Athlone, preceeded by a heavy shower.

Weird sky though. From up close it doesn't look like it should have produced much of anything. Just a slightly darker patch of light cloud away north of us now

Cape values have increased for Leinster today on the overnight runs.

Similar sky here in north county Dublin. Heavy rain, more nimbus-looking sky, no no sign currently of the high temps and humidity forecast for today

I posted that just after I got onto the train and the air back home felt quite fresh. Am now in the city centre and both temp and humidity are appreciably higher. If this persists, it's going to be stifling.

As an aside, I see ESTOFEX have issued a level one and two warning for some parts of the UK, and our whole island is under a sferics watch

Clearing here now in Kildare. Plenty of convection now

A brief thundery shower recently in Monaghan, all of 4 rumbles.

Possible thunderstorms when these hit land in the southeast maybe?
They seem to be building too.:)

North Eastern UK getting a nice show.

A nice cell east of Cork City, headed NE.

Hopefully not. The heat and humidity out there now will help sustain it

pad199207

It hasnt rooted into the boundary layer, died off now
