They either had another look at the charts, or maybe they are monitoring this tread.

Soooo happy with that - it was really misleading - makes so much more sense now

it seems to have been changed and that line taken out of it now

Saturday night will be cold and frosty again with lowest temperatures of -2 or -3 degrees generally and freezing fog will be widespread. It will be cold and frosty on Sunday morning too, but eventually temperatures will reach 4 or 5 degrees during the afternoon. And when the fog clears on Sunday, the weather will be bright and sunny for the few short hours of the day. The continuing presence of an anticyclone close to Ireland will ensure dry weather for the first half of next week at least. But the nights on Monday and Tuesday will be particularly cold again with temperatures dropping down to -5 and -6 degrees in parts of the country. And daytime temperatures up to Wednesday will also be low.

They have changed it again now
"And daytime temperatures up to Wednesday will also be low. The forecast for the rest of the week is uncertain but latest indications suggest cold possibly wintry conditions returning especially to northern areas "

I was speaking to a person in the south of the country last nite and speaking about the weather the person said " sure all the cold weather is gone for a while" meaning they were thinking for a good while!

It's weird because it was released at 09.30, according to the website, which means they had access to all the 00z runs which unanimously show a cold northerly plunge for the exact time they predict southerly winds and higher temps

That often happens at ME-probably a junior forecaster that was out on the beer last night...

IF this northerly pans out as currently projected,expect a lot of snow in west munster including cork city! as occasionally heavy shower activity spreads in on nnw winds from the atlantic under the influence of an exceptionally cold feed.
The snow shadow in this one will be south and East Wicklow,Wexford and waterford...Except when winds go NNE or NE occasionally

So is MT'S forecast still on track & will we,as Bastardi said,be in for a huge winter event in the next 2/3 weeks?:eek::eek:

Yes.

My email to Met Eireann was very promptly replied to and I was told that the forecast had been changed, as we have seen. I'm unsure if Met Eireann look at boards but I'd imagine they do.

They certainly do access boards, they even have an account and they have posted a few messages in the past. Whether they read the forecast threads and other discussions is another story, I reckon they won't confirm it even if they do.

Going by the gfs, the north, northwest looks spot-on for some fanatic sea effect snow, the east less so for now anyway, but as we know things could and will change as we get the next few runs,

But what a run, you lads in the north might want to keep an eye out for icebergs

I doubt very much if temperatures will get anywhere near -5 on Tue and Wed.
We'll be under a blanket of cloud as the high stagnates resulting in the dreaded anticyclonic gloom, nearer +5. Wait and see.

IF those charts come off, most of Ireland would be likely to see some snow. With uppers at 500 hPa nearing -40 and uppers at 850 hPa dipping to around -12/-13 there definitely would be larger disturbances/troughs/lows that could whiten large swathes of land:D

Never mind the ECM, they bring down a large low pressure in the flow.

Why would they not confirm it if they are already members here?

Just wondering what the abbreviations ECM and also FI stand for???

ECM is actually ECMWF

European Centre for Medium-Range Weather Forecasts

FI is fantasy island.

ECM is one the models that people base there forecast on , not so sure exactly what it stands for .

FI = Fantasy Island ( A chart that is outside of a reliable time frame of 96Hrs + plus usually)

Its lake effect snow but when it happens over the sea its called sea effect snow, its what caused most of the snow the east got the last week

Was talking to my friend from my old course in Ucd doin climate science , he said the lecturer who's a climatologist was saying that we could be seeing some new records set on snowfall by the new year!

RTE just said they are not expecting snow during the first half of next
