Bump. A few of the lesser models pushing the storm further South again and UKM hinting that there could be significant changes in track and intensity before Weds night.

Might be worth a decent discussion on a weather forum?

This is a very interesting development indeed because just yesterday, the GFS had downgraded this system a bit, and had it much further south as a weaker disturbance. That might have given a bit of snow to parts of England if that had happened, with Scotland possibly missing out on that altogether.

Now, this system has been upgraded by the models once again, and it will be interesting to see how long it will take for either the Met Office or Met Eireainn to officially name that system as Storm Fionn which of course, is the next name on the list. The BBC's Week Ahead forecast did have this part of the world, getting some snow from that system, especially over high ground and yet, most of the models had the snow risk further to the north on the latest runs that I know of.

This means that we would just end up getting rain from that here in Edinburgh if that came off, although these models did still have the strongest winds being to the south of here. Nevertheless, the position of that low pressure system would then only need to be adjusted a bit further north for the Central Belt of Scotland to then come under the firing line from those high winds and so even at this stage, there is still a lot to play for here, with just about all outcomes in terms of the position of that low pressure system, still possible.


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.

The Big 3 have the centre of the low crossing central/southern Scotland on the 00z output. And as was the case yesterday on the 12z, around 50% of the GEFS show a very brief mild sector affecting Glasgow and about 5 affecting Aberdeen.So it looks like the track is fairly settled on now as somewhere through the southern half of Scotland.

Winds don't look too ferocious either which is good. The VERY good news is that it is looking promising for a notable snow event in central Scotland late Wed/Thur morning.

This definitely looks likely to be the main weather event of the week. Key factors are:

1) Max gusts don't look exceptional but very strong winds are expected over a large area

2) There is the potential for significant disruption during the Thursday am rush hour 

Here's the Arpege 00z view for 03 GMT, Thursday 18th January.

Even though detail and exact location have still to be fine tuned I suspect warnings may be issued for both wind and snow later today*. Midweek certainly looks interesting.

Looks like we'll be pummelled in my location by snow tomorrow and then strong winds from this storm late on Wednesday and I must say - the snow is looking much more appealing to me as it stands. 

Great to have such variety in the weather though this week

Good ole winter storm. Luckily we are not in a sequence of high tides, so prone coastal areas maybe spared somewhat.

Interesting how each run shifts the little zipper slightly. Seems some areas are going to have to huncker down more than other areas, but the effects seem like they maybe felt nationwide.

Posted this in the MOD but probably better here..

The LP looks slightly further South to me on the 6z run. I don't whether it's me over looking but it also looks to have more of a south easterly trajectory as appose to the 0z and previous runs where it barrelled west across Scotland. Maybe me over analysing...

Totally agree with your observations. The Scottish mainland looks relatively unscathed by wind on this run. Strongest winds, at the moment entering the west coast of northern England exiting the Wash area early hours Thursday morning. Still time for changes yet! The only crumb is this thing is moving so quickly.

Although not in the same league (modelled - might change a bit) as the Burns Day storm of 25th Jan 1990 but the general set-up and track is very similar, albeit projected SLP won’t be quite as deep. That storm brought widespread storm force winds to a large area and in many ways had more of an impact than Oct 87 as the worst occurred during the late morning.

I see the blended trend continues to take the centre a little but further south, increasing the risk of a big snowfall in Scotland and reducing the area affected by the strongest wind field.

It was inevitable that it would move south when the Me Office issued a snow warning for here! Sod’s Law and all that.

I’m still not convinced the final track and intensity are nailed down yet. A little strengthening and it may end up further north a little weakening and it may be a bit further south and I feel that may not be known until closer to the time.

Exciting times. North Yorkshire northwards in the firing line for snow on this run.

Max of 2c here, but on the wrong side of marginal for now.

Plenty left in this one yet.

GFSS 12z now showing it will be England (except the far N) and Wales which will see the strongest winds - but much less stormy than what was showing yesterday.

In other words:-

A bog standard wet/windy episode.

Some snow likely to the N of the Low. For us in the S:-
