Day 2 Convective Outlook
VALID 06:00 UTC Mon 14 Aug 2017 - 05:59 UTC Tue 15 Aug 2017

ISSUED 21:00 UTC Sun 13 Aug 2017

ISSUED BY: Chris

A complex frontal system will move out of Ireland into western and central parts of Britain during the day and overnight. There is a signal for a split-cold front in the warm sector ahead of the main surface front, and this could aid in the development of embedded convection within the larger-scale frontal rain. In turn a broad isolated area has been created with the lightning risk translating north and eastwards through the zone during Monday and Monday night. It should also be noted cold air advection aloft may help to generate some post-frontal convection across western and central Ireland later in the afternoon and this could produce some small isolated convective cells with the potential of a few lightning strikes and perhaps some small hail.

Netweather have upgraded the possibility of thunderstorms in Dublin over the next few hours.

The rainfall radar is getting intense atm as well.

Some sparks now in Co. Louth. http://brunnur.vedur.is/athuganir/eldingar/i_dag_na.html?

Latest strike just on the north Dublin coast.

A few rumbles over Swords around 30min ago.

Mad looking cell north of Delvin, co Westmeath

Thunder heard south of Roscrea - Templemore direction

A couple of flashes and distant thunder getting closer here in south Laois..

Meteorite58

A cluster of strikes now between Templemore and Rathdwney.

Garden and the street is beginning to flood herein Naas now, very heavy rain, 32mm has fallen

Danno

Good few rumbles from Rathdowney, 8 miles west of here up the river.

I wonder will the SE get a few sparks before the rain clears late tonight / early morning. Still have conditions for lightning into the evening.

Meteorite58

Looks like a squall line near Belfast atm

jimmynokia

Teeming rain DN 22

Meteorite58

An interesting echo return near Belfast a short time ago....

Trebor176

Very heavy rain a little while ago in Clondalkin. No thunder, though, despite the dark skies earlier, and the biblical rain.

pad199207

Massive drops of rain here and hail falling now

Meteorite58

Detected sferics today. Heavy convective rainfall was the main feature.

Any opinions on met's forecast for tomorrow for thunder and lightning?

Thundery bursts is not the same as thunder and lightning

Thanks, I'm well aware of that.

Is that a regional forecast?
National forecast And graphic makes no mention of T and L

Leinster and Dublin.

I think ME changed the wording of the forecast earlier. I read "thundery bursts" in an earlier forecast and clearly the screenshot above shows a change to T&L.

Decent chances for today with the incoming front.

Could be some very heavy falls of rain in the east this evening!

A band of precip is developing now, stretching from east of Sligo town to east of Limerick city and down into Kerry. A few bright or sunny breaks ahead of it so this band may be the interest for this afternoon/evening.

A lot of the parameters there for lightning potential today but only a couple of sferics . Wondering why. Was looking at the mid and upper temperatures and wondering if they formed a cap or were just neither warm enough or cold enough to produce instability ?

Meteorite58

Tomorrow night / Fri morning look very interesting on the Western side of the country as a trough goes into a negative tilt and showing a lot of potential ( in my amateur opinion ! ). Most Notably I think cold mid and very cold upper temperatures passing over the warm SST's at this time of the year with plenty of warmer moist air lower down to get the convection going. Lapse rates are impressive.
