Just noticed Wednesday's low which might have some interest for some be it heavy rain/snow/wind:

Any significance to it having 180mph jetstream just to the south of it ?

Er that is why it is deepening perhaps?

Dartmoor sticking out here in the maximum wind across the 12Z Euro4 integration with 40 mph sustained winds:

I expected to see the first ring of this low on this 07:00 near realtime
synoptic , this morning, but nothing there.
http://meteocentre.com/analyses/map....eur&size=large
Will this low develop north of the max curvature on the 528 DAM contour?
currently between 20 and 30 deg W

I monitor the met. for the potential of marine flooding, prior to this
big data sea level predictor
http://www.ntslf.org/storm-surges/la...ort=Portsmouth
I've no idea how much account that model can make of upper air effects,
when the sea level isobars have not even formed of this low yet.
ie will that 0.5m or so surge prediction increase over today? At least
the timing is out for high tides coinciding on the central south coast
overnight tonight

I got that totally wrong, the first ring of the low appeared on the
08:00 plot, now to try and see what predicted that position.

I've been watching that for a while, some of west Cornwall's strongest winds come as a NW funnels around Land's End following this sort of feature.

MetO currently forecasting gusts 60mph in sheltered Penzance, with the wind offshore. If that's the case I wouldn't want to be on the north coast, except for extreme windsurfing. https://www.youtube.com/watch?v=Dh4ucQxtKqM

Assuming the loop in the 1016mB will become this explosive cyclogenesis
low of tonight, the geopotential seems to be placing it farther south
than the models including MetO have placed its track. No longer crossing
Ireland so worse for any English channel sea level effect

I would have thought it's too fast moving, as well as not being much of a feature until it gets here (and even then not that deep) to have much effect.. Also, as far as the south coast of England is concerned, the strongest winds will be offshore.

On the north Cornish coast, where the strongest onshore winds could well be, the late development of the feature means no big swell. In fact not much swell at all - http://magicseaweed.com/UK-Ireland-M...ts/1/?size=940 . 10' wind wave forecast for Sennen, it topped 30' of real swell on 8th February, 38' at Sevenstones.

That was the event of the winter by a big margin http://www.sennen-cove.com/8feb16.htm
