I have got a horrible sinking feeling for anyone looking for cold and snow south of Birmingham . . . I expect downgrades over the next few runs 😞

Most definitely yes.  It will be very interesting to see how they treat the ridge, and the associated Azores low.


 



The mean looks solid with regard with that concern the japs played with it last night as mentioned also by Peter last night, but having said that the recent jap run 0z has dropped that idea so jap and ecm run to come will be interesting.

haha its not you guys that we're worried about! (snow-wise, not flooding wise)

Although to be honest I would settle for anything as long as it is drier.

The GEFS12z don't seem a 'downgrade' at a glance. Snowrow is the highest its been for London.

Let's look at a chart that is 10 days away and almost an outlier on the ens and scream downgrade.
Laughable is a word I would use
The gfs has been up and down like a yo-yo.
Ukmo looks good and that will do me

True, although there are a few niggling runs that barely get the cold going at all (although that turquoise one, P7, dips down and goes cold later)...

Points of note:



  • Higher median (and mean, but that's less useful)

  • Far more scatter in the latter stages

  • Milder runs start at 168 at 12z, rather than 240.

There is no question the output is exciting but I think its best to keep our feet firmly on the ground.


The chances for a cold spell look good but a few potential hurdles to surpass first , the further north you are the better. Fingers crossed.

Why are we so desperate to see the negative. See the positive and if the negative happens, shrug your shoulders and move on.

It's the normal for extreme weather to be downgraded the closers you get to the event especially when originaly viewed from a week or further away, and this downgrading happens with all types cold, heat, snow, etc. Though less often downgraded with rain & wind, but that's because we live in mild ocean driven climate.

We rarely get more than a 5 day cold spell in southern England, so its no real surprise. We just have to manage our expectations and hope we get a second bite of the cherry later in the month or February

Anyone living on or near the South Coast will most certainly not be counting any chickens with regard to this pending cold spell...my motto,based over many years is to expect nothing and any snow that falls is a bonus....obviously a different story further north...For my winter snow fix, If I am lucky a trip up onto the Downs might provide some of the whitestuff...or my annual trip to the Alps at end of Jan may weld yield positive results!

This time around it's the entirely typical post-97 situation whereby for most of us it's actually quite marginal. The models wax and wane, then from time to time you get a run which has large amounts of flipping even in the ensembles. The 12z GEFS isn't close to the worst flips (they have been known to happen even as close as 48 hours), but it's a good example of how a rock-solid cold spell (from 168 to 240 on the 6z) can be frittered away.


Sometimes it's the beginning of the end (as in 2009), other times it's just one of many wobbles (2010).


Time will tell in this case, but sufffice to say I've been rather cautious this time round, I've not talked to the local papers (as I did in 2010 to 2013 when snow was on the horizon), nor have I said much to the powers that be at work (which as it's a school is always keen to stay open).


I generally want a minimum of a full day+1 run of solid looking ensembles from ECM and GFS before I'll commit to it looking likely that a snowy spell is on the way - and that's not happened. Not yet, anyway!


It will get much colder than it's been recently, of course, but until I start seeing MOGREPS on board for say, Reading (safely away from any maritime gridpoints), I'll not get too excited.


MOGREPS can be seen here btw:

Yup, that's the MetO site - it uses the MOGREPS median for the longer term bit of its forecasts, as far as I'm aware.
