Small nuances aside the GFS 12z follows much the same theme as earlier, the Atlantic still well in control and with this worrying theme of height rises to the South by mid January


UKMO looks wet and windy all next week with GEM potentially stormy for a time thereafter before pressure builds to the South and SW later in its run.

Interesting as GFS has completely dropped this dartboard offered by GEM on the 11th. EDIT as mentioned already by Fothergill above.

In addition reading between the lines of the Met update today the snapshot that came to mind was a pressure build to the South for a time in the middle of the month bringing possible drier and milder conditions at times in the South and East. The ECM update will be interesting in what it shows at Day 10 tonight in whether there are signs of a pressure build to the South and SW on that run too.

To be fair Martin you actually have to go beyond day 10 to get any notable height rises to the south. This morning's ECM op and to an extent ensemble data, GFS and ensemble data all had some form of ridging/height rise to the west or northwest. What comes beyond that would surely be even more uncertain than what is at 8 to 10 days out?

I still think there too much uncertainty to suggest anything other than an unsettled and possibly mobile picture with milder and colder interludes in the mid-term.

GEFS12 update shows a big spreading developing towards mid month but most runs going average to mild.

I've given up the ghost chasing cold this winter, we had the building blocks in place but heights continue to problematic to our South and any cold remains in the realms of deep FI. The Nino has scuppered winter IMO and February cold rarely floats my boat as 2013 showed around these parts, I do expect a cold spring which again is as much use as a chocolate fire guard. Taking a break from model watching as I can safely say rain will be in the mix on a daily basis for the next few weeks.šŸ˜”

Wednesday not looking a day to be outside on the ECM op. Has the leading low a bit deeper than GFS or UKMO. Rather parky in those winds, with the 528 dam line over the Eng Channel.

Just looked at the ECM 12z run. What seems pretty clear to me about it is that while it doesn't show a freeze or anything approaching it, neither does it suggest a return to the exceptionally mild type of zonality that dominated both November & December. Temps much nearer average I would deduce from that run.

Was thinking the same. Despite the apparent lack of any deep cold on the horizon in most output, predictions of mild well into January seem equally wide of the mark for most. Cooler zonality with some snow looks to be on the menu for some with moderate elevation in the north if some of the current runs are correct.

ECM 12z tonight keeps the Jet flow well South at 10 days so things not too mild and with Low pressure still close by to the South heights to the SW are kept at distance at this time but to me there are signs that the Jet flow will be re- orientating further North in the following days.

Maybe not the most exciting set of 12z runs if it's cold you're after but not without interest - suspect there'll be a few wintry days up North and some pretty windy weather for all at times. Given the regularity that the models keep throwing up nasty LPs there must be a reasonably high possibility of one of these verifying, which will be 'interesting'.


The GFS ens nicely highlight that whilst average to (a bit) mild may be the most likely outcome down South, there is enough uncertainty to suggest a low possibility of a cold spell occurring. 


On the Euro High 'trend' - imo the GFS has had this as a distinct possibility in FI for a while - there's been a few members going for this, a few for HP to the South West/West and a few others going for HP to the North West or indeed the East. Can't see that this has changed tonight, it's just that the Op has picked one of the Euro HP solutions this time round, rather than the West based HP offering from this morning.

After today I'm going to do something I've never done before in January and take a 2 week break from model watching and everything weather .


The combination of endless wind, rain and mediocre temperatures throughout is a tiresome prospect. This is the 3rd consecutive winter now and its wearing.


Time to concentrate on a new hobby..a thing called life.

Does anyone bother looking at the GFS parallel run?

6z certainly has an interesting stonking massive arctic high then scandi high at the tail end of the run.

Look on the bright side.  At least we have TWO to moan and groan with like minded people!
