You can view them on Meteociel there's three small links just above the map. 850s are in the middle

The latest Met Eireann monthly predicts Atlantic making a temporary return late next week. They say the last two weeks of Feb will be dominated by easterlies with high pressure not the north.

That would be very good. Is Weathercheck responsible for writing the update;)

It would be in line with what the CFS has been showing for a while too.

Would I be right in saying that GFS 12Z is bit of a downgrade?? The cold only really lasts 2 days, hopefully the ECM one is accurate one and the GFS upgrades to that over the next 24 hours.

Snow showers in to the east Sunday afternoon on the ECM...we are narrowing down the start point.

Yes downdgrade from the downgraded 06z. We are down to a brief cold snap;):p

Very positive start to the ECM but need to watch what it does with next week.

Gonzo

The GFS 12z isn't great. Hopefully an upgrade on the uppers and duration on the pub run and most importantly into tomorrows runs as we get closer. Hopefully the GFS soon backtracks on that big mild low pressure blowing up over us next Wednesday/Thursday. The GFS operational run has a good deal of support for this to happen so it has to be taken onboard.

ECM 144 is crucial

TheMilkyPirate

For people getting confused with talk of downgrades and bad runs. This spell is pretty much locked in for Sunday and lasting a few days now. The downgrades are with regard to the length of the cold spell.

ECM is not going to last much longer than next Tuesday either by the look of it

Gonzo

not liking this ECM, could be a fairly significant downgrade, looks like mild is making inroads at 144 hours.

Longing

The man from Del Monte says No

Snowbiee21

Ecm says NO

Slashermcguirk

It sounded from Met Eireann that this very cold spell is pretty locked in. Would be surprised if that is not the case?? they seemed pretty bullish about it. I havent seen the charts yet but all talk about very cold weather next week.

People getting upset about 6+ days ahead

Really?

Gonzo

at 168 hours the cold spell hangs on for Leinster and Ulster. Could this be a battleground. This run is better than this mornings for the brits.

Okay I’ll take that back, the latter looks good. I was to quick to judge one frame

Kermit.de.frog

Don't take anything beyond 120hrs at face value. Even 96hrs is a push right now. ECM is fine anyhow.

Slashermcguirk

I wouldnt be that bothered about 6 days ahead, lets just get the initial blast of snow for a couple of days, i wouldnt be as concerned about day 6 or 7 this far out.

dexter647

I would not be to worried about anything past 120hrs...Cold weather coming looks farily nailed on so anything after that is still up in the air imo:)

PokeHerKing

-10 uppers for most of the country from Sunday through Thursday on the ECM. Theres no downgrade on this run

Gonzo

just checking back on the 06z and this ECM 12z is a bit colder for Leinster and Ulster overall. A bit of a downgrade for the west and south-west tho.

Kermit, you have taken on the status of a John Giles at half time in a Ireland match in the 90's. We all turn to you to find out how things are going even though we are watching ourselves!

Course that raises the spectre of there being a Bill and a Dunphy on the weather forum too.....

Long time lurker here, and total amateur. Would you mind posting a link to what you just looked at. thanks.

Cant all be good this far out. Its one of the big ones though.
Hopfully ECM sleeps well tonight and wakes up the right side of the bed in the morning.

Not getting near those temps down in these parts but ironically could do very well snow wise nonetheless.

Do look at the sticky at the top of the weather forum for weather links though - lots and lots more out there

TheMilkyPirate

That +168 is much better than expected. As I was saying this is locked in now for Sunday on, longevity is all that's left to iron out.

Surely time for a dedicated technical thread
