As I suspected Helen's Bay seems to have recorded the most rain from Monday/Tuesday's event - had my rain gauge been working :rolleyes: I'm sure I would have recorded something similar or perhaps even more than 54.2mm:

that shows about 40mm for ballykelly so that must mean something close to 30 -35cm fell on the hill behind me.

Good forenoon everyone.

Light rain here, hopefully it will get heavier. How come the UK met office radar has most of Ireland cut off?

Must have rained on that hill owen, same thing happened here... one of the mountains was covered in snow, a cloud covered it for a couple of hours then all the snow had gone, then it was back again the next morning, meanwhile other mountains around it still had snow.

Su Campu · 02-04-2010 11:09AM

The Valentia 06Z sounding shows some marked mid/upper level cooling behind the front, with a convective temperature of around 7-8°C. With further upper cooling taking place throughout the day and a good clearance already making its way through Kerry and Cork, we look like we may be in business later!

WolfeIRE · 02-04-2010 12:02PM

Fairly typical Easter weather I must say.

dloob · 02-04-2010 12:52PM

Just bit overcast in Galway at the moment, 9C and drying out from the earlier rain.
Ohh and a big shout out to my top compatibility matches from yesterday Deep Easterly and Weathercheck, WolfeIRE was on there as well

This is the nearest AWS to me that I know of, 30mm between Monday and Tuesday morning.

Fair enough!

. Didn't get quite so much this side with a daily total of just over 20mm, which accumulated over much of day by light to mod rain with just the odd heavier burst.

Looks like it could be a clear case of snow theft then.

Just a spell of light/occ mod rain here to with 3.6mm recorded in total. Clouds are trying to break at the moment but not really being successful as of yet.

We need to keep an eye on how temperatures are reacting tomorrow afternoon, if we get above 8 then we're in business!

Reached the magic 8.0C here!:pac: The sun is yet to show itself though..

Just broken the 8.0c barrier here, and there is a couple of light looking showers breaking out to my east. Su's 8.0c theory seems to be working :eek:

Edit 2.27pm. Heavy shower now, although clouds don't look that dark or sinister. Rain rate at 17.1mm/ph

Trogdor · 02-04-2010 02:33PM

Up to 8.9C with the sun out now and a bit of cumulus around

Deep Easterly · 02-04-2010 02:40PM

Despite the benign looking cloudscapes here there seems to be heavy showers breaking out at random in my locality. Still raining here but much lighter. 1.2mm so far since it started around 2.25pm. Temp back down to 6.5c at the mo.

Edit: Rain Rate back up to 18.0mm/ph

Edit Edit: Signs of intensification as it moves to my north:

Sharp clearance just to my south. Still stuck under heavy spurts here. Total from shower so far at 3.0mm.

Su Campu · 02-04-2010 03:21PM

Showers are just starting to pop up on the radar now, and should intensify over the next couple of hours. The 12Z sounding shows a cool surface (6.2°C), but further inland temperatures are now up to 10°C and the latest satellite shows the convection nicely. Note the small circulation forming to the southeast of the Wexford coast, it's almost like a pseudo polar low system, but without the weather!

We should see maximum activity up to around 6pm before things start to diminish.

Su Campu · 02-04-2010 03:58PM

That little circulation off the southeast coast seems to be in an area of increased upward motion (cyan) and cold temperature advection (dark blue) at 700hPa. The very steep low level lapse rates cause strong upward motion, which leads to the formation of the small meso low.

Deep Easterly · 02-04-2010 04:14PM

Skies are moderately convective here at the mo but sunny spells are scant and very brief while temp remains stubbornly low. 8.1c currently. All the darker stuff is to my south and west.

Seems to be a few sharp showers bubbling up at the moment over parts of the midwestern region in particular:

Edit: Nice if small looking shower moving over Galway Bay/North Clare at the mo. Current Docks cam grab:

redsteveireland · 02-04-2010 05:08PM

Nice heavy hail shower just passed through here. Bigger hail than I'm used to seeing. Hope there's plenty of that on the way.:D

Deep Easterly · 02-04-2010 05:43PM

Skies are pretty demented looking to my SW now but all it is doing is preventing any sunshine breaking through thus keeping it cool and damp. A definite NE breeze now, so an inflow thing going on at the mo.

Su Campu · 02-04-2010 05:56PM

C'mon c'mon, let's get going! :mad: It's not turning out quite as planned in the east anyway, some shortlived cells alright but I thought there'd be more oomph to them! Galway and Clare seem to be doing the best out of all this though, with some red returns just north of Galway city.

dloob · 02-04-2010 06:09PM

Plenty of hail showers in Galway City over the last few hours.

Deep Easterly · 02-04-2010 06:09PM

Ditto. Mad looking and dark here but shower won't hit me. Looks to be weakening rapidly on its SE flank*..

* the bit that is heading for me

Oscar Bravo · 02-04-2010 06:18PM

Very heavy shower here in Castlebar around 5pm,however theres not much more on the way by the looks of it.

Deep Easterly · 02-04-2010 06:23PM

Shower is just refusing to make it up here. Would go for a drive south but can't be arsed. Ah well, nice to see some half decent convection going on anyways.

Shower made it up after

Heavy hail and rain shower at the mo. Winds have dropped of to calm and shower still looks like it is decaying rapidly. Feeling quite cold.

Su Campu · 02-04-2010 07:04PM

Yeah, it didn't go quite to plan, it seemed as soon as the temperatures were high enough, they got knocked back down by the very showers they were making! :rolleyes: But hey, it's only early April....this was just a taster! And then there's July, with its Spanish plumes. I bet this year we'll get one drag 25°C dewpoints up this way and set off an MCS the width of the country!

And it'll happen just when I'm away on holidays.... :rolleyes:

Was just thinking the same thing myself Su, surface heating just didn't get going. I would estimate about 30mins total sunshine here today due building showers. :mad:
