Absolutely rotten weather here (Collooney) this morning, shallow flooding in some places on the roads already. Cold and miserable... yuck!

*Drat should have checked my station before leaving the house this morning. Think a battery change might be required

Frankly Wexford looks like getting away Scot free from this one ( and Donegal more or less) and it may only be a fringe event in Dublin. Cork/Kerry up to the Midlands is the main soak pit.

Mount Dillon and Moorpark are notably missing as I post.

Johnstown Castle 3.8mm.

Cork Airport recorded 24.4mm ( and 6mm the previous night as the system came into Cork and the S/W before midnight)
Gurteen 26.9mm
Mullingar 25.6mm
Ballyhaise 24.4mm

In contrast

Dublin Airport 9.3mm
Mace Head 9.5mm
Johnstown Castle 3.8mm
Sherkin 0.9mm

So the worst rain fell inland in a band from Cork to Cavan and would include Moorpark and Mount Dillon. The system sort of tore across the west coast ( Sherkin 0.9mm) and slowed down as it crossed the Midlands and moved NE.

A slow moving band of fairly heavy and persistent rain is pushing into west Munster.

Good shower, heavy, thundery but I heard nothing.

1.5mm in just a few minutes / little more than 7mm/hr though so not a tropical monsoon.

Sponge Bob, IanCar, or anybody else with an idea, let me know what you think of this. During a disastrously wet summer for farming I have been watching the radar on a daily basis trying to get work done between the downpours.

I have observed a tendency for organised bands of thunderstorms to follow the general path of the river Shannon from south to north in a consistent manner. This path (maybe 30-40km wide) from Limerick/West Tipp north to Sligo/Leitrim/West Cavan seems to be followed, even if winds (and often clouds) are actually being driven by south-westerly or south-easterly winds.

It seems to occur mainly as I say with trains of thunderstorms, but the development/direction of the wave (was it a wave?) in Thursday morning's front appeared to do the same thing (at least with respect to the intensity of the rain)....i.e. as the front passed from west to east it seemed to stall around the Shannon basin, intensify and the heaviest of the rain took this general path northwards along the Shannon. As a result we ended up with about 5 hours of torrential rain (over 40mm) while places 40km east or west recieved relatively very little. If it is possible to view an animation of the radar from that day it can be seen?

Anyways, Thursday aside, could there be any possible mechanism whereby thunderstorm cells are somehow almost "drawn" towards the path of the river Shannon even when wind direction would be expected to take them on a different trajectory???

The lightning strike cluster along the Shannon in the linked post by lostinashford shows a perfect example of this from last August. Let me know what you lads think...am I barking mad on this one?...:D

EDIT: just noticed this post from RickyLovesYouAll from that day which backs this up
http://www.boards.ie/vbulletin/showpost.php?p=80057467&postcount=1907

By the way I had observed this tendency locally in previous years but it is easier to identify with the wonders of rainfall radar technology!
