Model Output Discussion - Spring Has Sprung
johnholmes replied to Community Team's topic in Forecast Model Discussion
Not a full post but just showing the latest NOAA 6-14 day charts. Both have a gneral rather cold westerly 500 MB pattern. Not yet showing any signal for deep cold from a northerly point. The contour over southern England on the 6-10 day is 534 DM which is quite cold so even lower further north. Any ppn in the north would likely be snow and over most hills further south possibly lower at times depending on the actual synoptic pattern.

Metwatch Re your comment about heights over Newfoundland. That area is often close to or withing the main major trough so all the heights show is that the trough is not centred over that area. It is shown east of Newfoundland on the 6-10 and west on the 8-14. -
Upper air analysis 26 January 2024 One week on so another update; not done earlier as nothing was showing on any of the 3 charts to suggest anything even slightly different from our weather this past week. NOAA 6-10 has slowly over the past week changed troughs/ridges, or at least, some aspects in the far west. In the UK area/Europe then the European ridging, more especially, the position of the +ve heights has shifted from way east to a more westerly point ( on the 6-10 it is now centred 50N 20W at 210 DM. This movement is not dissimilar to how it developed prior to the last cold spell! I’m not saying this will happen again simply stating facts. The 8-14 edges it a shade further west but, as is almost always the case, with a lower +ve height value. ECMWF shows a general flow just north of west on its output (31/1-4/2) with a flattish upper ridge over central/eastern Europe being replaced by a flattish trough in much the same place. Its 850 temperature values eventually by day 5 the 0C lying from N Wales to the Thames estuary. UK Met on their 3 day charts from T+144 30/1-1/2 a mainly westerly flow with an upper ridge finally settling just west of Portugal So all 3 show a similar upper air pattern developing over the relevant periods of their forecast period. As is often quoted on the model (forecast) thread, more charts are needed to see what is likely to transpire.

I am pretty sure that meteorologists and climatologists will probably already be preparing learned texts explaining why certain meteorological parameters are now different to what we remember, in my case, 60+ years ago. Just whether they will be proved correct is something that will be evident in a decade or several decades time. I'll watch with interest from my 'perch' up above! -
Very well said C, as an ex senior forecaster for the often maligned Met Office much of what you discuss was barely seen in my days, an occasional very complex item in the more learned scientific magazines certainly nothing in practical meteorology. The science of meteorology has come a long way since then but some of you on here, yourself included, absolutely amaze me with your depth of knowledge. Keep going at it you will never, in my view, get a total answer but you will become more accurate as will the professionals. Thanks for all the hard work you and others on here do, way above me much of the time but well done.
