Thanks, sadly that was more of a rain event in my area :sorry:

It was a marginal affair. Some got a couple of feet, other nought.

Widespread snow warnings for Northern Ireland. However North West expected to receive the most and the warning is 1 level off amber where as other areas its a couple off it.

Cold northerly winds will bring frequent snow showers through Thursday and into Friday. Be aware of the potential for disruption to transport networks.

A cold airstream will be in place by Thursday afternoon, bringing frequent snow showers to areas exposed to the northerly wind. A further 2-5 cm of snow is possible, with an additional 10-20 cm above about 200 m. Lightning may be an additional hazard, with possible disruption to power supplies.

Excellent stuff!! So effectively what they are saying is that areas above 200 metres could get close to 40cms of snow!! Thats unreal!

A Scandinavian High means that the winds across the Uk and Ireland would likely be Easterly and continental in origin. The air would therefore be colder than you would get from a Northerly or North Westerly.

 

 

Not always colder than a Northerly. Less chance of modification yes but in 2010 when Northern Ireland's record low temperature was recorded, that came from direct Northerly, then a high moved over us the day after, so  arctic air from the North was sat over us. The day time maximums were extreme too, colder than any Easterly I remember. We often get half baked Northerlys so I see where you are coming from.

I'm going to say 10cm for near Lisburn at 200m

Latest update pretty much the same- 

Outlook for Wednesday to Friday:

Turning much colder during Wednesday and Thursday. Very windy with frequent wintry showers, significant snowfall in places especially from later Wednesday, and drifting over higher ground.

Looking at the UKMO run, this could push into Saturday as well. A 3/4 day cold snowy spell is not to be sniffed at.

Just a heads up that we will be updating our snow warnings this evening. Could be some pretty significant snow for some places along with high winds, blizzards and possible thunder & lightning thrown into the mix. Stay tuned.

Is XC weather a credible weather site?

It uses the latest GFS data(updated 4 times per day) and automates its FC from that. It has lengthened the cold spell for my location. From Wednesday evening onwards the temp remains at 2c or lower until midday Sunday. Last night it had it had the cold spell ending Saturday.

I will go for 1cm if I'm lucky at my location. So miss Dec 2010. Even here we had 8inches and sub zero temps day and night. Barely get a flake now.

A nice easterly to end the ECM!! I really hope this comes off just so everyone is happy. If we can get snow on the ground later this week then god knows how long it could stick around.

Yes. Places with a good covering could have it for a long time if the ECM came off. Of course the upper temperature increases but the surface would be much colder if we had a clear high overhead.

Easterlies pffffftttttttt

Still a hell of a lot better then sw Winds. Ireland is overdue  a good easterly at some point,one where some real proper Cold reaches us from europe before running out of steam before it gets here.
