Potential Snowfall & Cold Spell Discussion (Wednesday/Thursday 30/12/09)

peasant · 30-12-2009 10:09pm

What I don't understand is the following:

On the sat image you see this area north of Ireland where warm and cold air collide (red circle). There are clouds, there must be moisture, there's lots of movement, you'd expect all (snowy) hell breaking loose

Yet look at the same area on the radar and it's dead as a dodo ...nothing happening at all. Even the showers moving in from the NE die a mysterious death in the no-snow-bermuda-triangle

can somebody pleez explain ?

You love rubbing it in our faces don't you! But you do provide us with great pics, so I suppose you have the right.

Those capable of taking a technical stab at it are running for cover - they all face perm bans now for getting this so wrong.

Ah no ! They're good lads really:D

inabina · 30-12-2009 10:14pm

THEORY - is Sellafield keeping the Irish sea artifically warm thereby preventing snow on east coast? Are the brits to blame?

Actually if you check the T&C's of the forecast for 1ft of snow in low lying Dublin you will see the punishment for getting it wrong was a voluntary permanent ban from this site for WC, SC and all the other experts. No doubt they will do the honourable thing here. I mean we could have had the National Guard flown in based on their forecast so I think its fall on the sword time here folks. Sad, but true.

Supercell · 30-12-2009 10:16pm

Pics tomorrow morning , if you think i'm going out into that blizzard and taking pics you is crazy!!

I thought when the rain went up the country it was to come back colder as snow.. Yep? what went rong or am I being premature?? Anyone wanna take a technical stab at it ?

if only forecasting cold weather was that simple;)
not a techincal stab, but from my experience of following weather and hoping for snow, on an island, surrounded by warm seas, from now on bear in mind that 9 times out of 10 widespread snowfall will not occur with a front coming up from the south west.
we always hope that just once it will come off but of course it rarely does because to use a famous phrase: what can go wrong will go wrong- be it dewpoints too high, dam thickness too high, 850 mb temps not cold enough. blah blah.

Hope you're right. In Maynooth, the temperature has popped back up to 2.8C.

Of course, if you ARE right, you can expect to be plagued with questions every time it looks like snow from now until March.

Are you shivering yet? Are you shivering yet?

hummm interesting gothwalk.....I bloody hope i'm right.. it's heavy sleet now.... come on the snow...

Update: Pictures taken 20.50 - 30/12/2009 Galway City !

-

Really Heavy Snowfall cant see it lifting over night or tomorrow as temp are'nt rising above "0"Degrees. Serious size snow flakes + No let down in snow as like hour ago still going strong!!:D

Forcast For Galway City :
Where will the snow get time to melt can't see it here ? Looks like it could be a trouble-some few days:D.

The vast swathe of cloud you highlighted is actually jet fibre, ie. high cirrus formed by the jet stream in the upper troposphere. It is not linked to the precipitation further south.

Here's today's 15Z SATREP

That can be the problem with IR Sat imagery - high cloud can block our view of what's underneath it.

gimpotronitus · 30-12-2009 10:20pm

Since WeatherCheck has presumably taken a voluntary permanent ban from the site due to no snow in Dublin, we need a new mod. I nominate myself. Anyone else?

PS. WC, we will miss you man.

I suspect that the two air flows aren't colliding at that point.
Looking at SAT24, it seems that those two flows are at different levels and the snow is landing some 200 miles out to sea past Galway.

But I'm non-weather-technical...

Hi Su. Im up the road in Lucan. I was wondering if you could tell me two things, one, do you think I might get snow here? also, if so, do you have any idea of the time? is it between now and 3.00? Im not familiar with charts so not sure if thats the time Im reading. Thanks

jenzz · 30-12-2009 10:22pm

Can you get banned for just being an annoying, argumentative Pratt ??

Hey Gracey

you ok up there ?

Min · 30-12-2009 10:22pm

I thought we were finished with the snow here in Kilkenny but not so according to Gerry Murphy.

ragg · 30-12-2009 10:23pm

RTE say definite snow :eek:

Deep Easterly · 30-12-2009 10:23pm

Temps on the rise here once again. Up to 1.4c with mostly rain with any slush melting.

Cosmo Kramer · 30-12-2009 10:23pm

Gerry's just said the word 'wintery' more times in the last three minutes than he's done in the last three years. He looked gutted about the whole thing...
