It’s only a forecast but if this came anywhere near, I don’t like our chances of any cold weather

 if this was to come to fruition then it would be like majority of the long-range forecast and we can possibly write at least one third of winter off

That appears when you clear the system cache or cookie data. Hope that helps. If you don't clear the cookies and cache data for this site it shouldn't come up again and mods feel free to move my response into the appropriate thread if need be.

Yes @Norrance December 2017 around the 14th (can’t be sure of the exact date) we got a good covering of snow down here (Hertfordshire) and I’m pretty sure that was from N Westerlys or a temporary Northerly. So they can deliver in this set up if it sets up just right . Then there was a repeat on Boxing Day . 
 

Back to here and now and the ECM not looking to bad , seasonal at least after the milder blip .

I would still expect to see a greater chance of blocking returning in the final third and I notice signs of this in the long range clusters tonight.

Shouldn't really comment on such long range output, but an interesting synoptical development, could result in a battleground scenario set up just ahead of christmas with energy perhaps splitting and the trough undercutting - all conjecture..

If above verifies it would also be the 9th year on the trot to feature a predominantly mild/very mild atlantic driven run in to christmas.. but then a possible change come christmas itself as has happened on quite a few occasions after such mild run ins, 2008, 2014 and 2017 good examples.

My main goal is to get some pressure on that PV with some wave 2, to give us hope for the second half of winter, if we can achieve good things in the process of doing so then great.

A pretty severe 6pm run yesterday from the Arpege showed gales widely for many western and southwestern parts that's likely and most models show this but another zone of interest was a zone of 75-85mph heading into Wales and through the Midlands then close to the London region with gusts of 70-80mph that would certainly be very disruptive not to be taken too literally ofcourse. 

Wind gusts from that yesterday evening's chart..

EUROPE_GUST_58.thumb.jpg.0f02709d1d2df8d6b0fed7a6df212c13.jpg

Detailed numbers in mph below..

18_59_ukwindvector_gust.thumb.png.d156871af6563aeb909a161c5adc3658.png

Note there is a small disturbance "kink" in the isobars this is what those very high gusts for more inland regions are in association with ofcourse the behaviour of these little lows within the flow are important as to how things pan out during tomorrow night. 

Worth bearing in mind Arpege does tend to over do wind gusts but nevertheless knock 10mph off those values and some disruptive weather would still be likely for many. 

Anyway in its midnight update a lessening of peak gusts especially for those central regions but still 55-65mph progged.

18_60_ukwindvector_gust.thumb.png.0f689e8a1e0535895ce19a020959560d.png

00_54_ukwindvector_gust.thumb.png.1546f83e6e528f87116fa5329ed0b390.png

Not all models agree however and a less severe scenario is possible but I feel the midnight update from Arpege won't be far off at all although I expect gusts will be higher than Arpege shows for the Irish sea and Ireland. Also potentially very strong winds northerly winds for the far east of England come Monday morning too. 

Looking at Tuesday an incoming frontal system likely brings very strong winds 40-60mph quite widely then a spell of heavy rain with a pronounced and intense squall line indicated by the sudden bend and opening in the isobars to the left of the tightest squeeze. With much colder air tucking behind and wintry showers for the north and west behind this.

The hideous Euro trash high making an unwanted appearance on the GFS this morning.

Seen that wretched high ruin countless winters since the late 80s

Thankfully the ECM has other ideas 240 still to rôle out but hopefully more WAA in towards Greeny

not sure where this is going!! Anywhere but a euro high will do , it does look like heights are pushing up from N Africa though

EC  has potential for those up North and with decent altitude...

I would take a stab at anywhere over 300m in the north west will do quite well , 

And ends a little differently to previous op runs..

Could go either way looking at the Jet, digging south to our West, heights rising to our SSE!!

Interesting to see the orientation of UKMO at T120 is subtly different from GFS, delivering potential for a much more potent north-westerly on Thursday/Friday.

Contrast this with UKMO which is quite juicy:

Rain may turn to snow on its back edge during Tuesday evening for Scotland and perhaps parts of northwest England and wales shown mostly on hills. Don't take the detail too literally at this stage from the chart below but the potential is shown.

The second half? The first half hasn't started yet! Let's get to the 22nd Dec first before writing off half the Winter.

First couple of days coming into view - Miles into FI I know but hardly disastrous charts to see in Winter, they will be different next run but just showing writing off the first half of Winter at this point would be foolish.

With a generally dismal outlook for cold weather fans, let's hope P9 of the GEFS trumps the pack!

You know things are bad when you have to pluck one ensemble member out at 15 days away for a good chart!
