Well really just 3 days away, this time 3 days we will be seeing the cold push in the 850hpa temps dip to -10c and dewpoints drop like stones, then snow showers should begin to be created in the Irish sea. All going well.....

Hope your right.

I'll ask my usual.. Whats the chances of some snow in manky wet Waterford next week?

If all this comes to pass, then there is a very good chance indeed, and it would be more than a short flurry...:pac:

Assuming this comes off, is gonna be the scenario where the east of Ireland will get a lot of snow, whereas wetern areas will get a lot of clear weather?

Great explanations lads very nicely put.
I always look in this forum but have no idea what im looking at in the charts.
So sneachta is on the way !!!!!!!!!

cheers black and dark !

I'm the exact same, read the weather forum loads but don't know how to read the charts.

Snow would be awesome, a lot of you are saying snow in the "East"... I'm in Louth, I suppose it won't come far enough north

expect nothing, that way you can't be disappointed, and anything we do get is then a bonus:)

Depending on which model you choose, the snow chances seem to range from a brief snowfall event Monday-Tuesday (GFS) that would probably amount to 5-10 cms in some parts of eastern Ireland, to a longer period with about the same amounts followed by more 2-5 cm falls each day next week.

So it's definitely better than nothing if you want to see some settling snow, however it would be the southeast and parts of Ulster that stand the best chance of seeing a significant amount.

Charts looking fantastic this morning.

For once we look like being in a good position.

I would probably advise against following the GFS, changing lots on each run now UKM and ECM are less volatile...... in the medium term this is.. towards +120/144.

In the shorter term for Sunday night/ Monday / Tuesday things looking like getting more certain.

An intense cold pool will push in during Sunday afternoon with 850hpa temps touching -12c perhaps at times in the east. Dewpoints will drop rapidly. Snow showers will begin to form during Sunday evening and progressively develop and become heavier and more frequent through the night.

Monday will be a very cold and snowy day in the east with temperatures around 0 or 1c with dewpoints down to -4c or -5c. For once the showers will be snow! The snow will stick readily and most places along the east coast will recieve at least 5cm through the day with places locally recieving upto 15cm's The snow showers will continue through Monday night with troughs and prolonged showers likely.

Tuesday will start icy with showers in the east but a band of sleet and snow will push from the east, things will begin to become slighltly more marginal however ECM/UKM give a period of heavy snow for much of Ireland through Tuesday with SIG accumalations. GFS gives a more sleet/snow mix as DP's rise to 0c-1c.

From Wednesday onwards things are very uncertain, however it is likely to turn slightly less cold, still frosty and maxes of no more than 5c before a possible northerly moves south.

Overall Sunday evening, Monday and Tuesday offer the best chance to see a decent accumalation of snow for Dublin since 2001.

Some Great Looking Charts!!

The UKMO have stepped up their Weather Warnings overnight to include eastern counties of Northern Ireland from Tue onwards, Hopefully that'll be a good indication for those of us on the East Coast!!!
