    and the cold is gone on the 6z. No surprises there when the GFS ensembles had no support for cold in the first place. The operational just kept spitting out the coldest most unreliable chart possible over the past few days, it's so bad it makes the CFS extended look good.

    It's away cross the foam Gonzo but it's not completely gone

    Yeah, rather than a total about turn we are seeing downgrades of the cold to a local pool in much of England with the deep cold well to the east . These downgrades will likely continue on the next run. Although I would be amused if it showed another potent easterly moving westwards towards us, but that is highly unlikely now. Still if the scandi high can remain firm we may get another chance after mid month when the mjo is in a more favourable phase for blocking. The danger is the westerlies get back in though and we have a couple of weeks of fully mobile weather. I am still of the view that March could be quite cold.


    Wrong chart posted above - that was the pub run special from last night.

    Gavsweather vids today called out the GFS for what it is, an abysmal run of failures since the update went live at the start of the winter. Just about everything past the 120 hour mark hasn't verified by the GFS since early December.



  • Moderators, Science, Health & Environment Moderators Posts: 17,411 Mod ✭✭✭✭Gonzo


    The Pub run is at it again, lovely easterly and unstable too, and just in time before it's too late. Better keep dreaming.

    If only this could verify, 5 years chasing an easterly.

    Looking at the longer range models both the JMA and CFS are going for a very dry and anticyclonic February so very little measurable rain until at least the 3rd week of February. After this there are hints that northern blocking will get going into week 4 and this may begin a pattern shift as we transition from February into March.

    Looking at the CFS extended a cold to very cold March is looking possible with the type of weather we so desperately wanted in January and early February.



  • Registered Users, Registered Users 2 Posts: 1,541 ✭✭✭esposito


    Always the way. Still, if we get something similar to late Feb to Mid March 2018 I won’t be complaining.



  • Registered Users, Registered Users 2 Posts: 6,467 ✭✭✭highdef


    1 to 5 cm of snow, best case scenario. Yay. Sure I got about 4cm of snow in West Leinster a few weeks back.



  • Registered Users, Registered Users 2 Posts: 2,934 ✭✭✭sparrowcar


    So then you won't begrudge us east coasters who have got very little this year. I'll take a few cms near the coast thanks, better than nothing.



  • Registered Users, Registered Users 2 Posts: 6,467 ✭✭✭highdef


    Too true. I got lucky in my Midlands location. I was only expecting 1 or 2cm from that spell. Having said that, it wasn't a big dumping of snow or anything, far from being snowed in but the local roads required great care.

    ECM for a few runs showing little rain until later next weekend or into Monday 13th, then showing heavy frontal rain around Monday/ Tuesday with possible strong winds and blustery for a few days and introducing colder NW'lys with wintry precipitation along Atlantic coastal counties. That's if that HP can be budged. Better chance of getting the cold form that direction than from the East at this stage, GFS gone right off any source of cold . GEM very like the ECM.

    The Jet looks to sink further S and as the HP slips away may introduce Atlantic weather for a time with some Polar Maritime influence ?

    The last two runs from the ECM backed off the cold, showing to be on the milder side now, some rain at times but not much in general, lots of dry spells.

    Next Mon looks to hold the frontal activity, GFS also showing it , GFS much windier than the ECM. GFS does go on to show it cooler after the front goes through next Mon, GEM has pushed out the cooler air. All very.....you know....Spring like 😁

    A very mild outlook indeed. GFS similar to all other models showing either mild or exceptional mild conditions to dominate our weather over the next few weeks. After a mild January, February is on target to be exceptionally mild so this winter overall is likely to finish up milder than average despite December being slightly cooler than average. Temperatures in the low to mid teens later this week and into next weekend, if this is combined with sunshine then it will certainly deliver a taste of early Spring.

    Looks very dry over the coming week but by mid month we probably will go back to a more unsettled pattern, but nothing too wet showing up on the models at the moment, certainly nowhere near the deluge conditions of the recent autumn and then the second half of December to early January period.

    If we are going to get any cold this month we may have to wait till the final week of the month, however the cold is looking much more likely for March.

    Oh I hope that everything you say is true @DOCARCH ! This drier and generally fairly calm weather is just brilliant. I'm doing outdoor chores in comfort the last few days. I was walking in the lower fields at the house in longford yesterday and there wasn't as much as a squish underfoot. The ground was very walkable. Another month of fairly dry weather would mean that solar radiation would be beginning to kick in, in terms of drying the soils further.



  • Moderators, Science, Health & Environment Moderators Posts: 17,411 Mod ✭✭✭✭Gonzo


    CFS really going to town on delivering a significant pattern change from the final days of February and well into the month of March.

    Untitled Image

    Turning chilly end of February with parts of the UK going into the freezer.

    Chilly opening week of March with north-easterly winds at times but will it be cold enough for snow?

    Untitled Image

    Another blast end of 1st week of March and into the second week, on this chart Ireland narrowly misses out on a direct hit.

    Untitled Image

    After this we go high and dry and staying very chilly.

    Later in the month we get a very cold northerly and go into the freezer in terms of upper air temperatures.

    Untitled Image

    The above probably doesn't mean much as this is the CFS but it has been sticking to it's guns for quite a while now showing a very chilly March overall. Definitely a trend here for March to be quite different to what we have seen all winter.



  • Registered Users, Registered Users 2 Posts: 12,881 ✭✭✭✭average_runner


    The media are playing up a "beast of the east 2" for end of Feb

    Anything to sell papers



  • Registered Users, Registered Users 2 Posts: 2,420 ✭✭✭Cork2021


    It was just on the news headlines on Newstalk! I’m the most amateurishly weather enthusiast and I bleeding know this is bull



  • Registered Users, Registered Users 2 Posts: 1,705 ✭✭✭Billcarson


    Well there is a ssw likely next week which does increase the chances of a cold spell down the line. It wouldn't be too surprising if we did indeed get a cold spell late feb/ early March. It might lead to something, it might lead to nothing.......



  • Registered Users, Registered Users 2 Posts: 2,420 ✭✭✭Cork2021




  • Registered Users, Registered Users 2 Posts: 7,442 ✭✭✭pauldry


    Frost and Dry weather is what Sligo is getting. East might get snow but too early to be mentioning Beasts. Could be one of the colder Marches. Probably the coldest month of the "Winter". Even though its Spring.

    There is a wide range of possible outcomes with what can be considered a cold spell and there is a heightened risk of cold weather regardless of the major SSW due to MJO. However, the major SSW will still be a key player in possibly getting wave-breaking and anticyclonic conditions building further north compared to previously whereby MJO amplification will have been killed off by an intensified polar vortex. Also there's always an increased chance naturally due to the time of year with spring incoming and everything winding down aloft plus we haven't had a March cold spell since the St. Patrick's Day weekend of 2018 unless you count the low cloud/foggy spell of early March 2021.

    Terms like Beast from the East should be reserved for only the top end of easterlies such as 1956, 1987, 1991 and 2018. Just the usual media spouting bullshit that shouldn't even be getting a mention. Pointless and a waste of time.

    All I want is one more decent cold spell this winter. The weather can do what it likes afterwards........



  • Moderators, Science, Health & Environment Moderators Posts: 17,411 Mod ✭✭✭✭Gonzo


    A few of the GEM runs playing around with things turning colder into the final week of February. There are about 4 members doing this, hopefully more will join over the next couple of days.

    Untitled Image

    GFS ensembles show nothing too cold yet however there is a definite cooling trend now appearing for the final week of February.

    Untitled Image

    We are likely to see an increase in members turning cold from the 24th of February over the next few days. Of course upper air temperatures right now are well above average and will stay that way for another 10 days at least.

    Even if we were to get a beast from the east for a few days in February (very unlikely), this will still finish up a milder than average month as temperatures will be well above average for the first 3 weeks of February. The month is also likely to finish up much dryer than average, however the final week is likely to be somewhat more unsettled.

    Winter 2022/2023 will finish up milder than average yet again after a very mild second half to December, a mostly mild January and very mild February for the most part.

    Can’t believe it was mentioned on Newstalk just heard it on 11 news. Ridiculous.



  • Moderators, Science, Health & Environment Moderators Posts: 17,411 Mod ✭✭✭✭Gonzo


    The media just can't help themselves with rubbish articles relating to the weather and nothing whatsoever to back up their claims. The next 2 weeks is looking mostly dry and mild. What happens after that remains very much to be seen, we may turn cooler in the final days of the month but it could be just temperatures closer to average. No guarantees of anything properly cold on the horizon other than chasing a few cold outliers for the moment.

    Just an observation regarding GFS ensembles. There is a number of colder members cropping up in the final week of February, which may or may not be linked with the SSW. Worth keeping an eye on over subsequent runs. The 06z is top. Yesterday's 12z is bottom

    Irish Times, the self declared paper of record, also climbing on board



  • Registered Users, Registered Users 2 Posts: 1,541 ✭✭✭esposito


    Now Rte radio 1 mentioning it. Discussing it on Drivetime soon 🙈



  • Registered Users, Registered Users 2 Posts: 2,836 ✭✭✭.Donegal.


    Yeah the tabloid nonsense is what it always is. Rte has a piece on it now but it’s saying it “could” bring colder weather but that’s not always the case and explains what it is. Nothing wrong with that IMO

    Paul Moore is a climatologist with Met Eireann and he explains that it usually takes two to three weeks for a sudden stratospheric warming event to have an effect. "Every sudden stratospheric warming is different and not all of them disrupt the tropospheric patterns below. For example, the event in January 2019 did not significantly disrupt the tropospheric patterns below and had no effect on the weather patterns over north-western Europe.

    "The event in February 2018 caused major disruption to the tropospheric patterns below and led directly to the colder than average temperatures in Ireland during February and March 2018, including the very cold outbreak from the east culminating with storm Emma at the end of February and beginning of March 2018."

    Is this the first of the colder charts starting to appear? Not that I would take it seriously as its too far away and it's the gfs but it will be interesting to see what happens in a few weeks time.
