Perhaps,but there is far more interest in the now and the very soon.  Tally's maps above show snow for millions in the SE for example.


Edit:


Tomorrow morning will bring a fair bit of snow to parts of the south east

The weak band of precipitation getting all the way south this morning, and the potential for another tonight into tomorrow, have only materialised at short notice. Hopefully that will translate into Tuesday's precipitation being upgraded in extent, intensity and persistence, so that it too can make it all the way to the South Coast.


Failing that, localised areas of higher instability look possible over the SE in particular. Coupled with tomorrow's potential, it seems that area might do relatively well for snowfall.


There I go glancing at the details when I'm meant to be taking a break... old habits die hard

NAVGEM still good


GFS has a cold surface high. Better than mild westerlies I suppose

These little troughs/disturbances popping up at short notice are awesome. I love the fact its down to nowcast situations, makes for a far more interesting and exciting outlook. When it snows at my location of course.

The trouble is with temps hovering around zero at night and up to +5 or +6c by day it's only cold enough for transient wet snow at best. Basically a waste of time for southern UK unless you've got some altitude.

NAVGEM upgrades the cold out to day 6 on its 6z run @ 144 with a more potent NE ly and the high nudged NW.  A trend worth looking for on the 12zs


the 0z run had a reload from the N by 180 hours....

Quite possible. Some of the lesser models are hinting at a potent easterly, but until ECM shows any interest I would be very cautious, and the ECM ensembles seem to have backed away this morning.

Definately something interesting on the GEFS ensembles, HP migrating north not south on most.

The EPS has to be fair backed of slightly today, but on the whole the OP has been on the mild side of the cluster.

Actually think there is a lot of promise for the NE in these charts, the point between the axis of the ridge of the HP and the easterly winds often forms a convergence zone, and it looks like the NE is at risk of convergenze zones for several days towards the end of the week, perhaps even besting the SE if we do get them.

Remember the NAO is a meaningless figure. It is derived from the charts, not any sort of driver. If the charts are wrong then the forecast NAO is just as wrong.

Bird table model (BTM) is back in action, having been first used in December 2005.  A jay and yellow wagtail have visited the birdtable this afternoon.  Rare visitors indeed. I think they must have had a look at the 5 consecutive days of snowfall alerts on the Met O website.


The forecast from BTM 12z here is Brrrrr.  Tweet.
