Yes. This morning I flagged up the possibility of a very wet Saturday. Definitely something to watch. All in all it continues to be a very interesting period of weather.

From the beginning of November there appears to be a lot of cold weather moving in to Eastern and Northern Europe, hardly surprising for the start of November but was seriously lacking last year.

There will be big issues with flooding around the Midlands, Wales and N England if this turns out to be a wet winter.

This weekend has a well-forecasted pulse of warm air from the south tangling with cold air over Scotland - latest GEFS suggest the heaviest rain will be N Wales & NW England rather than BBC suggesting S Wales/Midlands last night. Some wet snow over Pennines?


Once that's out of the way, HP for most of next week with the possibility of LP encroaching from the west. GEFS op and control runs say generally dry and on the cold side, though it's possible to cherry-pick exceptions. Presumably cold air following this weekend's weather gets established. Inverness has an impressive collection of snow row figures, though very little actual precipitation - just flurries?


GFS has abandoned its end-of-run northerly blast which was showing yesterday and replaced it with a less dramatic one a few days earlier. I'll believe that when I see it in actuality.

The QBO pattern is being compared with 2013/14. Of course it is only one of many factors, but if the winter follows a similar path flooding would be a major problem I think.

I know automatic IMBY weather forecasts are a bit dubious, but I'd like to bank this one for Penrith that predicts an accumulation of 40cm of snow :-)

Well - very cold ensembles for Aberdeen!??


Averaging around -5c @ 850hpa for the next week - maybe a tick up to -2c @ 850hpa in day days time but still well below the seasonal average and of course this is a long way off.


I am keen to know what the CET is for October!? Could be the first colder than average month since..!??


March 2018? - and when did we last have a colder than average October?

The Met office charts have fronts all over the place,


especially the T+24   (0.00 hrs 25th)


Following the sequence through the 36 hour and 48 hour suggests Central and Northern England is going to be very wet, it will also be windy

there are also yellow warnings for rain at the weekend

ECM still going for a developing low atop the UK for this time next week while GFS maintain the settled outlook. 

It's usually GFS that like its lows!

I said earlier on the oct precip watch board that in the last 30 days ive had 140mm of rain. Potentially by the weekend i might see 200mm of rain over a 30 day period.


 


Thats a good explaination of why our ground is so swollen...

GFS and associated GEFS move to a northerly scenario next week, HP to the west of and often close to the UK, temps below average as you might expect and mainly dry, though some GEFS runs have rainfall from (probably) the HP regressing a bit and allowing LP to come down the North Sea.


But ...


BBC last night was talking of a butterfly effect. If the warm air to the SW strays only a LITTLE bit further north, then it interact interacts with the jet stream and spins uo a new depression to move NW across N Britain. ECM 0z has picked up on this idea.

ECM looks Scandinavia high like, good to see early on

GFS 0z has HP over UK slowly subsiding south over next week, to be replaced by cold NW-fed depression, looking quite vicious around Monday 4th; ECM 12z (Fri) and BBC collapse the HP earlier with depression moving in from the SW mid week. ECM looks similar to the GFS by the 4th but with the depression then standing off to the west rather than being over the UK.


GEFS runs generally dry util around 2nd Nov then rain with biggest totals in the south. Cold, too, though Op and control have a brief bit of warmth around the 1st-4th, the majority of runs (and the mean) keep it cold.


Don't see any sign of a Scandi high

Significant shift towards a more unsettled outlook with the Atlantic eventually punching a long way east. Could quickly revert back of course. Perhaps.

The 00z UKMO has us in High Pressure much more - Sunday to Thursday next week from this Sunday W/E.


GFS and ECMWF- are struggling to bring the Low Pressure breakdown - by either Thursday or much more likely by Friday next Week - they expect Wind and rain, areas of dry and bright breaks with Low Pressure wind and rain that could cover the UK N NW Europe and the North Atlantic for at least 5 days.


Climate is warming up, Scotland and N Ireland and North England still often gets some Winter frost, ice and snow, November to March, but the SE and South UK including S Central England and Wales, together with the West and North through the year, they sometimes get more rain than London and S SE England, where some longer dry fine spells without much heavy rain is seen every year.

The North Atlantic Sea often gets some much Colder Wintry conditions from November to March Months, and Mild SW and South winds tend to be more frequent over the East and SE of North Atlantic Sea, as the Azores High tends to stay in charge. 

With this warmth and heat, the Central and South UK has become mostly free of snow and frost.

06z GFS picks up a persistent pattern from 1-11Nov of a tendency for LP to our S and HP over the NE.


The way it's modelled, looks as if the pattern is hard to break. Could be interesting.

Officially cold weather watch starts with the GFS 00z tomorrow as the clocks go back. Good luck everyone if you want cold,mild,wet,snow wind or fog. Just remember don’t get upset, or you will be disappointed. Enjoy the input from everyone and don’t be too critical
