Obviously there will be some cancellations but it does not look nearly as bad as last time. I hope I won't eat my words of course!

to update based on this mornings TAF.
The “prob 30” stuff forecast yesterday has been "confirmed" and is now forecast to happen. Indeed the wind moving to the north with strong gusts is beginning and sleet is being reported in the actual.
What is interesting is they are now forecasting a Prob 30 of up to an hour at time (and a total of 2.5 hours) of proper snow with 1400 m vis between 0600 and 1100 . (So anytime now ish). The Global Forecast System (GFS) is predicting snow as far south as London so could get a cm or two on top of the sleet.
Conditions are still expected to clear clear up from noon onwards though knock on delays are likely.
Looking at the Eurocontrol tactical page for delays and restrictions:

EGJJ (Jersey) = Northwest strong F7 to gale F8, perhaps occasionally severe gale F9 until mid morning, decreasing strong F6 to 7 by mid afternoon. However, the airport seems to be 'Ops normal'.

Yes so 350 degrees means the wind is coming from the north not the south

KL985 AMS-LCY has gone around 3 times already. BA3281 IOM-LCY just went around as well and a couple of other flights are approaching or holding.
Edit: 4th (!) go around of KL985.

There is a noticeable low over SE UK with gusts of 40+MPH / knots on the Docklands forecast. Heading east pretty soon, but looks like a similarly low pressure are is following for Friday across London (it may shift away of course).

Currently facing a 50 minute slot delay on the BA833 DUB-LHR, with a summary from the captain similar to what was said above. Our itinerary to HNL is looking a little dicey at the moment.
So even if not cancelled, there are delays building up too.
