  1. That is good news. At least it doesn't look like mild breaks through other than for a day or so towards the SW. ECM 46 dayer seems to show similar pressure pattern to what we currently have. Cold temp anomolies for GB but neutral for us over here.
  2. Anyone know where ECM OP sits with wrt rest of ensembles suite?
  3. John Holmes on model thread has posted one of his NOAA anomoly charts - it shows cut-off high between N Scotland & SW Norway which could facilitate undercutting - John advises with his normal caution to wait a few days to ensure pattern persists. Backs up potentially ECM & GPS good runs tonight over UKMO run as per Mountain Shadow post earlier. Radar app - showers dying out for a time down the east coast (S Down & Leinster) and perhaps pepping up again later in night. Some showers look like making it across Scottish central belt out into Atlantic, so some showers could make it
  4. Weather app - wind shifting slighy north of east. Showers moving into S Scotland & N England from North Sea, managing to stay intact whilst progressing towards west coasts. Perhaps a small chance for E Antrim & E Down to get something out of this
  5. Showers have moved further up Co Down coast - some to hit Downpatrick & lower Ards peninsula. Unfortunately the wind is forecast to swing north east and the sea track becomes too short to generate further showers.
  6. Looking at a precipitation app on my fone, there is a band of snow showers coming out of Liverpool / North Wales, they progress west out over the Irish Sea but turn to rain. They are hitting the east coast from Kilkeel to North County Dublin and travelling onwards west. Away from the coast they revert back to snow. Looks decent intensity and you never know, perhaps form into a proper long lasting streamer.
  7. So anything we might get pre Thursday could be a brucie bonus
  8. That sounds really brilliant if it was to happen - just as i was thinking everything was starting to downgrade slowly day by day.
  9. Great news - which model is that? Do you know if the cold persists through the weekend, or, will we get a thaw and breakthrough of mild temperatures?
  10. For Belfast we need a decent length sea track to generate showers with the wind from east-southeast rather than direct east or north east. Here's hoping.
  11. The armageddon type cold for next week seems to have melted to slightly below average. Still no agreement on the detail for the snow event this Thurs / Fri across models, apps & forecasters.
  12. My memory isn't always the best but i think there were two snowy outbreaks up north in early 2013. One event caused huge snow fall totals - from memory it was a diving low directed south instead of east by a slack wedge of heights over Iceland - not sure what the pattern was out over Europe. The snow was not forecast (very much a now event at the time) but the 850s weren't spectacular. I'm only at 50ft asl and had about 18 hrs heavy precipitation of wet snow resulting in about 2 inches of slushy snow. About 2 miles from me at 200 ft asl had many feet of snow drifting in the high winds - true b
  13. I noticed this also. I know Met Eireaan use ECM for their app. I thought BBC did also through their weather services provuder the UK Met. But the BBC have changed their weather services provider, so maybe they use something else or a mix of models.
  14. I thought most LRFs were toast by New Year every year!!
  15. As well as big slow down in eastward progression & better snowfall prospects for all, Radiohead posted some charts on Model thread:- 1. "Milder" air reaches Ireland on Friday, temps ranging from 9C W Kerry, 2-4C Irish Midlands and 0-1C NI. 2. By Saturday, cold air coming back from east. Upper air 850 Temps ranging from -4C to -6C. 3. By Monday everyone under uppers temps of -10C to -14C. I would post his charts if i could but I can only work out how to post links on my phone. Hopefully all this comes to pass though if the corrections keep happening at this rate the
  16. That sounds really good for your location as the snow shouldn't turn back to rain and the mild air doesn't get in. Up here we will be relying on streamers / showers coming in off the sea - very localised hit & miss stuff. Still looking forward to the cold & frost. It will be difficult watching the news & seeing the various regions get their snow if it is green and not white outside my window! If you get good snow cover, you will get sub -10C overnight lows and barely reaching zero daytime. But you will want too much more corrections south west as it may not reach your locatio
  17. Latest GFS model run has very cold air in Scandanavia dropping into mainland Europe and heading towards SE England next weekend. Mild air gets into most of Ireland by next Friday though we should see some frontal snowfall Thursday night / Friday morning. Through the weekend the cold wants to head back westwards again and on Sunday temperatures for us range from 0 C across the northeast to 9C in southwest. At the same time many parts of England are circa minus 4C daytime and do not see any mild air next week at all. If this goes right, Ireland should be joining in the extreme cold temperatures
  18. Precipitation charts from various models show showers for east & south coasts Tuesday & Wednesday. East coast precip is in the form of showers, south coast in relation to its proximity to a small disturbance from Atlantic headed towards Cornwall & NW France on Tuesday night. Some model indicate modest snow cover from these events, others diddly squat. Still looking good for Friday's snow from Atlantic - lets hope it stays as snow, doesn't turn back to rain and the snow isn't a wet slushy mess.
  19. Just to add a snow cover chart for Friday to back up Summer Snows post. Looks like south & west will do better than north & east so most of the snow must be frontal snow approaching from Atlantic Thursday / Friday. If i was any way tech savvi, id have been able to post the chart instead of everyone having hit the link to download snowdepth_20210206_00_144.webp
  20. Its amazing how every precipitation and snow cover chart shows zip for Ireland with fairly strong winds. As you can see from the attached chart even the Isle of Man has 15cm snow cover. At least tonight Met Eireann is forcasting snow for Belfast this day week & zero temps though other media indicate this to be a snow to rain event. 534EE358-9BF3-47FC-A13B-BD53D40D845C(2).webp
  21. I think the chart shows temperstures are for midnight.
  22. As impressive as it is, the extreme cold has probably powered up the jet at just the wrong time for us. I know that some have said that in February it is possible for NE US/ Canada & ourselves to be cold simultaneously, however it is the depth of cold temperatures as the PV hits the Atlantic that has proven just too strong for heights to hold over here.
  23. In some ways i'm wondering if we would be better off if the major low at the end of next week didn't stall but carried on preferrably east but even northeast would do, so long as it advanced beyond the meridian. What causes this low system to stall - the temporary ridge extending down from Iceland on ECM 168 or the surface high over Scandi? Is this an example of high latitude heights not always assisting the chase for cold. I do of course understand that without the heights around griceland in the first place, we would never be in such an exciting pattern now.
  24. Look closer - there is 10 snowflakes showing for the Sperrins in Tyrone & 6 snowflakes for the Wicklow mountains. It's not all bad!!
  25. Getting this evolution nailed down is worse than getting a tooth pulled. You would like to think it will be sorted by Wed 12z or at worst Thur 0z. Hopefully thereafter we will only have to worry about longtivity and who gets the most snow. The current synoptic pattern does remind me of late 70's and early 80s. Maybe not having access to all the data we now have would be a blessing in scenario's like we have now, poring over every chart since the strat warming event.
