Cold Spell & Snowfall Discussion Tuesday/Wednesday (5/6 January 2010)

Was a quick heavy shower here in Gorey that has left a very nice covering, didn't last too long though, hopefully the first of many.

Temps here 0/-3 perfect! Streamers and showers developing and reports of heavy snow in gorey.... But irish weather network has my wind direction at a moderate NW 22Kn and so does irish weather network?? Weird and annoying.

EDIT: The M2 buoy is showing a NE of 44Kn!! Game on

Land readings are at 10m height, but the winds driving the showers are already veering towards NE, so don't be concerned with land wind directions

Looking further to the end of the week, a very potent Easterly to Northeasterly flow is modelled. 850mb temperatures will reach -10 to -11 in Eastern & Southeastern areas into Saturday & with a deep cold pool moving Westward over the Irish Sea, as I said last night, there is bound to be a risk of snowfall.

I may just be imagining this, but everytime Easterly / NE has been forecast during this spell, the actually airflow has tended to be more northerly.

A proper 90deg east flow would be nice, for a change. Probably need a Scandi high for that though.

2-4cm was hardly severe weather, maybe they are gonna replaceit with something more juicy though!

Temp and dew point rising a little here, a sure sign the winds are becoming more maritime, this bodes well.

i'm talking dublin/meath. the wicklow showers are dying out. they have been building up all day and are dying out. There's nothing building up on the irish sea to replace it.

ive said it before,for us in meath to get snow in this setup we need precip to form between the hook of N.I and the isle of man,it is slowly starting and given that met.ie are saying it will be 12ish tonight onwards before this happen's things are looking good for us and the east coast.
ive been waiting 3 week's and im not giveing up yet,patience all if it happen's it happen's if it doesnt i'll be f#####g stone mad :pac:

Ditto - up to -2.0c now, DP -2.9c. Thicker cloud rolling in.

2-4cm is enough to make a very messy commute in morning

Coastal areas of the northside might be about to get hit by a clump of showers. The Irish Sea is springing to life.

Very much agree with you there, it's been the case the last two times unfortunately and a contrast with February 2009.

However, at the end of the week, it does look like we will indeed have a very strong Scandinavian High, with winds backing progressively more due Easterly all of the time, certainly more Easterly in nature than they are now if the current Guidance is correct.

According to this, it should be snowing now but it's not

Thanks for that SA. Been looking at that closely since the weekend. The models are in general agreement that the front will slide down the west coast and will deliver little or no precip. It is such a close run thing at this stage. I would imagine if that High to the NW is affected in any way in the meantime, it will have a bearing on the atlantic system.

No problem.

Indeed, only a very slight shift could well bring the system onshore - significant for Western areas but it only requires a small change in the large scale pattern.

Certainly one to watch.

Snowing heavy right now if the wind stays at that direction NE looking at 6 to 8cm before morning.

I use this for wind forecast for windsurfing. Always fairly accurate.

Winds turning more northeasterly for dublin tom at 12.

Apart from the nice fall on new years eve and a flurry last night I'v been dissapointed we haven't has more snow in the east. Met E have been spot on IMO.

Well it's better than 2-4 They seem to keep upgrading it the closer it gets!

WolfeIRE

the north is certainly springing to life too

with the snow that is falling in parts of SE, is this precip chart not completely wrong?

I could swear I just saw a flash of lightning out the window about a minute ago. Might be imagining it though. If it was, it would be slightly north of east of Howth. Also, i can hear the sea very loudly here and I am the guts of 2kms from where the waves would be crashing. Wind must be going to get bad so.
