No signs of anything remotely cold in the reliable time frame then.


Please keep it succinct and substantiable ..........

Hear a pin drop in here and with this type of output I'm not terribly surprised.

ECM continues to set up a SW-NE Aligned trough with height retrogression in mid Atlantic towards Greenland towards T216-T240. This does not bring anything remotely cold to our shores (for now)..but it has to be said that developments to our N and NE are interesting and certainly sufficient enough for me to keep half an eye on. 


The GFS ensemble suite posted by Brian shows a definite progression to a cooler set up moving into November.


No chart available for the selected hour. Many charts start at 3 hours ahead, so if you have 0 hours selected try stepping forward or selecting a later hour.

Looking at wetterzentrale just noticed that GME has ICON in the same tab.Has it been upgraded ? or does anyone know what ICON stands for.

Read more at this link - see slide 9 onwards 2012 DWD report 


or on the Max Planck website here http://www.mpimet.mpg.de/en/science/models/icon.html


Maybe someone like Stormchaser can explain further what the benefits of the new model are. It is all just gobbledegook to me.

new, very high-res, icosahedral model that the DWD and Max Planck Institute are testing, so I understand

There may be a break in the well above average temperatures on Wednesday next week for Scotland and perhaps Northern England.


Otherwise, little change to report from the 12z models regarding the period Saturday to Friday, beyond which details aren't worth worrying about.


 


Longer term, GFS is consistently showing a displaced PV locating over Siberia, which raises the potential for a major trough east of the UK and a cold northerly airflow, and ECM looks as if it might be headed that way based on the day 8-10 evolution - so a few positive signs for cold weather fans, but very early stages yet and it could be a red herring for all we know.

That is different on Meteociel  that could be handy did not see that there.

Nearly two-thirds the way through Autumn now (how the time flies), and still awaiting my first decent frost or even a foggy morning of note. This must be almost without precedent.

GFS 0z and 6z runs both showing very steep temperature gradients over the UK for a time next week. This pattern has crept in during the last few runs and looks quite well supported by the GEFS.

The most remarkable thing weather wise in coming days would be associated with the amber weather warning for Monday and Tuesday for NW Scotland where up to 200mm is forecast for some of the hillier areas. More widely in the area there is expected to be over 100mm. Even for an area used to heavy rain these totals are very high for a two day period.

I'm seeing something interesting in the models, a significant westward displacement of the Azors high. This could come to nothing, and the arctic isn't playing ball yet; but a calm atlantic is more important than a calm arctic. Let's see how this pans out.


 


2023/2024 Snow days (approx 850hpa temp):
29/11 (-6), 30/11 (-6), 02/12 (-5), 03/12 (-5), 04/12 (-3), 16/01 (-3), 18/01 (-8), 08/02 (-5)

Total: 8 days with snow/sleet falling.

2022/2023 Snow days (approx 850hpa temp):

18/12 (-1), 06/03 (-6), 08/03 (-8), 09/03 (-6), 10/03 (-8), 11/03 (-5), 14/03 (-6)

Total: 7 days with snow/sleet falling.

2021/2022 Snow days (approx 850hpa temp):

26/11 (-5), 27/11 (-7), 28/11 (-6), 02/12 (-6), 06/01 (-5), 07/01 (-6), 06/02 (-5), 19/02 (-5), 24/02 (-7), 30/03 (-7), 31/03 (-8), 01/04 (-8)
Total: 12 days with snow/sleet falling.

Very nice day 10 chart from the ECM this morning. Not cold enough yet probably a month early but good to see.
