Some interest for the possibility of thunderstorms forming along W coasts on Sunday . CAPE levels not huge but a lot of shear available. Some very heavy rain possible in the W.

ECM 0Z and Rapid ECM 06Z showing potential for thunderstorms again tomorrow moving in from the W early morning and becoming widespread in the afternoon, mostly from W to E in the central 1/3 corridor of the country. Warm fronts followed by a trough providing the forcing . Warm moisture laden air mass with huge amounts of low level and deep level shear. CAPE not huge but with that amount of shear and vorticity in the atmosphere might be enough to produce storms. Possibly elevated storms again.

Will need to see tonight's charts and would like the views of others. Not too sure seeing such low CAPE readings.

Big rainfall accumulations showing up for the W, N Midlands, NE

ECM 12 continues to show thunderstorms from early ( around 10.00 - 11.00 ) moving inland in the SW, W and later in the NE as the warm fronts sweep up over the country. Showing the storms move from the coasts in over the midlands and peter out towards the E later in the afternoon.

Euro 4 showing thunderstorms but more a W to NE track and possible along S coasts . ICON having none of it. ARPEGE 12Z not showing much CAPE, AROME 12Z bit better.

Big Question marks about this one ????

No mention on MetEireann's latest update


' TOMORROW - SUNDAY 21ST JULY
On Sunday morning rain will spread across Ulster, Connacht and west Munster. It will extend to remaining areas in the afternoon and continue for the rest of the day. It will be heavy at times with a risk of localised flooding, especially in Connacht and Ulster. Highest temperatures of 18 to 21 degrees with fresh southerly winds, strong on coasts',

Day 2 Convective Outlook
VALID 06:00 UTC Sun 21 Jul 2019 - 05:59 UTC Mon 22 Jul 2019

ISSUED 20:12 UTC Sat 20 Jul 2019

ISSUED BY: Dan

Strong west-southwesterly flow covers the British Isles on Sunday, with a frontal system pushing across Ireland into western Scotland. Extensive cloud seems likely given deep moisture over these areas, with a broad warm sector covering Ireland during Sunday daytime - characterised by surface dewpoints of 15-17C.


Pulses of largely frontal (dynamic) rain will push northeastwards across Ireland and western Scotland, however there is scope for elevated convection to develop along the Theta-E ridge as a mid-level dry intrusion rides over an increasingly warm, moist low-level airmass. EURO4 / UKV / ECMWF have remained consistent in developing elevated thunderstorms late morning over the Atlantic to the west of Connaught / Munster, these then migrating northeastwards across Connaught in particular during the afternoon hours, and towards Ulster.

Confidence is rather low as to how much lightning activity will occur given rather weak instability and fairly saturated profiles, but the environment will be strongly-sheared and as such a low-end SLGT has been introduced. It is plausible there could be quite a bit of heavy (torrential) rain but a distinct lack of notable lightning activity. It is also possible other sporadic pulses of lightning could occur elsewhere in Ireland outside of the SLGT area, but it is rather difficult to be more specific at this stage - and adjustments may be required to the forecast.

While most convection will be elevated, should a stronger cell be able to root within the boundary layer then strong LLS, notable SREH and backed surface winds could allow a tornado to occur. In general, most lightning activity should decrease by the evening hours with only isolated strikes expected on Sunday night.

Status Yellow - Rainfall warning for Connacht, Cavan, Monaghan, Donegal and Longford

Through Sunday and Sunday night, falls of heavy rain will give high rainfall totals with reduced visibility and a risk of localised flooding.

Valid: Sunday 21 July 2019 06:00 to Monday 22 July 2019 06:00

Big flash of lightning and deep booming thunder in Letterkenny with torrential rain.

First flash of lightning I've seen in more than 2 years!

Chance this could affect The Open?

Very high.

Tee times were already brought forward a few hours but lightning in the area will disrupt it a lot.
