The mean here is completely pointless. A complete divergence within the ens

Perhaps the GFS computer saw my post lol. Heights building very late stages to the NE.

Is it just me or do you get the feeling it’s going to be a long winter of ups and downs for model watchers? 😎

Is it me or has ECM moved towards UKMO An improving picture for coldies.

cant rule it out for kent wet bulb T would be slumping fast in any heavy showers tough call as ever elevation will help

Interesting to see the raw 12z GFS as per xcweather has snow over parts of southern England tomorrow! I suspect I'll see a few sopping wet flakes in the heavier showers.

It’s certainly a finely balanced situation and I wouldn’t like to forecast the weather for ten days out (not that I would normally risk that anyway!). It could be anything from cold and wintry to mild and very unsettled or almost any other combination!

Would be a mild finish to November if it verifies.

The 12z ECM op and mean once again is pretty close through-out on the 850's

A highly amplified pattern does not guarantee cold for the UK as we all know, but there is no zonal outcome in the model charts I can see.

Pretty good agreement up until around the 27th between the ECM op and ens thereafter we start to see the two differ as the op goes down to around -5 but the mean goes up to around +1

NAVGEM has the low in the Atlantic closest to the UK this morning at D7

As of Saturday 17th NAVGEM was the best performing model

Before the Beast from the East events set in back in February, a lot of people were talking about the death of properly cold mid-winter easterlies and the fact that these don't happen any more in the way that they used to.

However, the last two winters in addition to the summer of 2018 has seen a lack of mobile, zonal westerly patterns for any length of time. With everything looking set for a possible blocked pattern during the coming winter which therefore reduces the chances of an Atlantic-driven winter, I am wondering whether or not, it is too early just now to be talking about the death of the mobile westerly pattern and seeing that as something which used to happen in the past, in the same manner in which we were doing with mid-winter easterlies before the onset of those above mentioned Beast from the East events.


The north of Edinburgh, usually always missing out on snow events which occur not just within the rest of Scotland or the UK, but also within the rest of Edinburgh.

UKMO probably the best still for colder weather as it has what looks to be more of a NE'ly flow at D7

Normality appears to have been restored since then, and over the whole period it still ranks below GFS, GEM, UKMO and ECM.

Off topic I know but our local reservoir is at the lowest level that I have ever seen now. If Nature is to reset the balance we are due a very large amount of ‘precipitation’ in the next six months or so - rain or snow. If not we are in for a serious drought next year (unless the summer is a washout of course).

The unusual weather (imho) continues.

Theres bags of potential for someone to get an absolute snowfest from this

Nothing like traditional zonality at all, still some blocky signatures about but without any meaningful cold. However I wouldn’t bet against a sizeable snow event this side of Christmas.
