Uh, sorry to burst your bubble I don't see any precip in the charts anywhere near 15-20cm. I reckon 2-5cm in most places would sound more realistic. If anything the 12z is a downgrade to what we've been looking at earlier. The front is struggling to make headway onto land as it is.

I'd be happy with a few cms of lying snow. Posted this in the other thread earlier.

That's good enough for most, so no bubbles to burst unfortunately. Still more than 24hrs away and still plenty of time for change, for better or for worse.

Mr Cumulonimbus

M2 buoy DP at 4pm was 0.3
Phoenix Park, 0.22
Casement Aerodrome 1.57
Dublin Airport 0.07

Dundalk currently 1.5. Creeping up all afternoon here.

Can anyone point me in the direction of hourly DP readings for Casement please?

xcweather.co.uk, click on Casement Aerodrome and current Dew/Temp is shown in the observation panel on the right hand side (currently dewpoint of 1c and temp of 2c)

Yeah !!!!!!!! Cork !!!! The snow shield is broke (I hope)

Zoom in and hover your mouse over Casement temp.

Well yeah any snow is better than none, but still, 15-20cm gives false hopes!

He wont have enough diesel to make it too far North though so we will send on some photo's:D:D

Why are the Streamers forming in bands along a NW to SE axis rather than a NE to SW axis in snow trains like 2010 even though the wind is coming from the NE. On the one hand it means the showers will last 10 or 15 minutes, gap, 10 or 15 minutes gap etc rather than when the streamers are aligned along the axis of the wind where if one were in the firing line of a streamer one would stay under it for a couple of hours continuosly. However this way it means a wider distribution along the coast North to South so more people in with a shot all at the same time. ie. in 2010 if you weren't in line with a streamer you got nothing until the winds or the streamer train shifted north or south a bit.

ie. if it stays like this and the shower activity peps up a bit more as it gets dark I think most of the East coast will get a light dusting as opposed to a dotted line of places along the coast getting a lot and the places in between getting nothing.

Regardless, its a nice surprise to see the streamers coming from the NE. I thought it was a due East wind progged for today.

Oh yea, another thing. The showers are forming in the lee of the IOM !! Where is the shadow. Does this means its the lack of snow cover on the IOM that did us in in 2010. ie Cold air from UK got warmed up enough passing over the IOM back then to prevent prevent enough convection along that IOM shadow sea track. Is the fact that the IOM got snow cover in last nights event the reason why its not moderating the air from the UK along the IOM shadow track to actually create the shadow. Maybe that explains why the Antrim coast was getting streamers in 2010 with a sea track that was half the length of the IOM shadow. Do you not need as much sea track for convection of the uppers are even colder which they would have been over Scotland and NI back in 2010???

So many questions

Firstly there not streamers, there just showers.

Also, regards to the lack of a shadow, it's most likely these showers are just the remains of yesterdays and today's front, pepping up abit as the front floats back west due to changing winds. Once the front completely passes and dies, then I say the shadow will appear once more. Hopefully convection will become explosive for a time later when it gets much colder, not much on current offerings.

Shouldn't it start falling after 6ish?

Presumably that would be for high altitude areas, like the Kerry Mountains? I seriously doubt he was implying that Cork city centre will be seeing 20 cms. Sure even a cm sends the place into chaos.

Looks like the south and southwest is going to get some overdue snow. How is tomorrow night/Monday looking for the East?

Live on the coast, in dublin and have to say i've given up. Been hoping and praying but this ain't happening. Sickening looking at the uk, the north, cavan, longford etc.

Anyway i'm out:(

On the latest HIRLAM the precip coming in Sunday/Monday is even further west and limited only to the southwest. You wouldn't want to see any further shifts westward there...

Not a drop of precip here.

But increased risk of the frontal feature over England late tomorrow feeding to affect northern parts of Ireland.

Thanks maq, have you a link to that hirlam you mention?

To a question earlier, the atmosphere is now definitely colder, however the action of the development of these showers mixes the air so with intense showers you get a mixing of the warm Irish sea into the air. However when these showers grow intense enough they will will quickly bring down the air temp in precipitation. And i would suspect instead of rain, in this type of cold atmosphere we may see graupel or hail type precip instead. With the cold uppers.

shootie

Woke up this morning to snow showers outside. Didn't last long but left about 1/2cm of snow around my house. I'm about 20/30m ASL in N. Wexford and can see the coast about 10 miles away. Seems as if I was on the boundary for snow as there wasn't any about 2 minutes down the road and none all the way to the east coast. Higher hills to my west had a great bit of cover though. First bit of snow around the house since Jan 2011, delighted. Expected nothing towards the south eastern coasts.

BEASTERLY

So what's your honest feeling? Few showers here and there nothing major going to happen??
