Weather Warning : Heavy rain leading to spot flooding Sat 10-8-19
-
09-08-2019 08:01PM#1Thought it might be an idea to put up a dedicated thread for what could become a very wet day especially across central counties.
Possible that we might see thunderstorms also with very heavy local showers.
No warnings in place as yet but the charts are showing some very high totals possibly leading to spot flooding especially after the heavy rain of the last couple of days.
As the LP system moves off to the NW tomorrow we get an active frontal passage over the country which could produce a lot of rain, possible warning levels.
Very little DLS but has LLS with a pronounced convergence zone especially across the center of the country, this could producing forcing along the front with thunderstorms a possibility.
Cooler fresher air mass to follow the passage of the front.

Latest AROME 18Z Showing some of the highest totals up until late tomorrow night ( will probably rain on after that too for a time ).
MUCAPE would appear to peak there in the afternoon as well possibly bringing some thunderstorm activity. will see.
Convective weather showing a slight risk for Northern Leinster into central counties.

Day 2 Convective Outlook
VALID 06:00 UTC Sat 10 Aug 2019 - 05:59 UTC Sun 11 Aug 2019
ISSUED 20:01 UTC Fri 09 Aug 2019

A vertically-stacked low will drift slowly northeastwards across Scotland during Saturday, the associated cold pool creating an environment with marginally steep mid-level lapse rates, and 600-900 J/kg CAPE in response to diurnal heating. Assuming sufficient cloud breaks occur, scattered heavy showers and a few isolated thunderstorms may develop by the afternoon and early evening hours.
Weak shear will result in "pulse type" convection, with slow storm motion bringing the risk of localised surface water flooding from prolonged downpours. This combined with fairly saturated profiles suggests the lightning potential is quite limited, and many areas within the SLGT will likely remain void of any lightning. A couple of funnel clouds will be possible as low-level vorticity gets stretched upwards by passing updrafts.
Cloud cover is likely to be fairly extensive across Ireland courtesy of several occluded fronts - however, 500-700 J/kg CAPE could develop by the afternoon hours. Low-level convergence along and to the north of the frontal boundary could allow some heavy bursts of showery rain to develop, with some sporadic lightning - although given saturated profiles and weak shear, the coverage of lightning is rather uncertain.0 -

Heaviest of the rain only lasted just over an hour with just pointless dribbles since. Still, managed to grab 20mm + within that small timeframe.
Nowhere near the scale of what Galway & Athenry experienced the other morning, but still, not bad.New Moon
