Looks like a shift south to me.

Ensembles for here . The mean is now -2ish here. Very interesting but massive uncertainty as highlighted by the spread.

Every year we get a storm producing wind speeds of at least that strength (74mph) here on the south east coast (as IDJ will attest to).  But for more inland areas its potentially quite notably windy. More runs needed before we know what will transpire, the storm is currently a fledgling on the other side of the pond.

According to the 12z GFS, the snow is the main weather story this week

That said, it'll still be very windy overnight at this end on Wednesday night but not exceptionally so.

Hope it's about 100 miles south, principally so MBY can remain under the colder air.

We are starting to get reasonably good cross model agreement on the intensity and track of this storm. GEM, NAVGEM, JMA and METO all in good agreement with ARPEGE and ICON. Central pressure around 970mb to 974mb at its peak.

GFS is a bit further south and about 10mb higher. It does have some support from the WRF model http://modeles.meteociel.fr/modeles/wrfnmm/nmmuk-2-60-0.png?15-18

and also from ECM. No UK chart for ECM at the key time as it only goes in 24hr increments. But this T72 chart for Germany is not far off what the GFS is showing at the same time.

http://www.meteociel.fr/modeles/ecmwf/runs/2018011512/ECD1-72.GIF

So still time for some changes but the general pattern looks fairly clear now.

We can now start tracking how the actual development of the system compares to the current forecasts. Current central pressure predictions per the fax charts are as follows:

12z Tuesday 1011mb

0z Wednesday 1003mb

12z Wednesday 987mb

0z Thursday 974mb

Solutions now agregating on a less intense system tracking a bit further South. We’ll soon know.

Interesting that the BBC graphics have changed even since the first BBC Breakfast weather at 6.15am, with the low being moved south and the snow looking like affecting N. England (N Yorks northward) and S. Scotland.

Looks like this has now been named Storm Fionn - hopefully it keeps on a more Southerly track to deliver a bit of snow here!:

 

Wind Warning for Donegal, Galway, Leitrim, Mayo, Sligo, Clare, Cork and Kerry

This evening and for a time tonight, storm Fionn will bring very strong westerly winds to Atlantic coastal counties with mean wind speeds of 65 to 80 km/h and gusts of up to 120 km/hr, strongest near coasts with a risk of flooding.

Issued:

Tuesday 16 January 2018 10:00

Valid:

Tuesday 16 January 2018 15:00 to Wednesday 17 January 2018 03:00

The "storm" looking bog standard now, and not quite the story some thought it was.  Head for the snow threads.

Seems to be some confusion in here this evening. Met Eireann have named today’s “storm”  Fionn as gusts of up to 120kph are expected on the Atlantic coasts of Ireland. The 12z fax chart showed a low at 960mb to the north West of the UK with an associated trough and a squeeze in the isobars. I think this is what is driving the orange warning that was issued and resulting in the naming of the system.

This has nothing to do with tomorrow’s storm which is still in the western Atlantic. I disagree that it is a non event. Latest Fax chart shows it at 980mb over the UK which is only slightly above what it showed yesterday. ARPEGE has the system at 975mb as it exits the east coast and wind gusts up to 120-130kph locally in parts of northern England. So it might still get named tomorrow depending on how the models look by then. I agree it is looking less significant than it was but to call it a non event is misleading.

This was definitely not a non-event. The Met Office upgraded their yellow warning overnight to increase the wind speeds. Gusts over 70mph include:

London City AP 73mph

Wittering 74mph

Cranwell 71mph

Aberdaron 78mph

Aberporth 71mph

Capel Curig 81mph

Liverpool AP 73mph

Pembrey Burrows 73mph

Lake Vyrnwy 76mph

Liscombe 74mph

Valley 73mph

Numerous reports of power outages across southern England.

The two main train lines from the south coast to London are blocked by fallen trees this morning. Portsmouth line blocked between Havant and Petersfield and the Southampton line is blocked between Eastleigh and Basingstoke.
