Delight - There is no such thing as too much headwind. But there is such a thing as too much wind to enable ground handling to take place. Most aircraft have limits on cargo and passenger doors, generally in the order of 60 knots or so. That means the plane may be able to fly, but without your bags. Sometimes because the the bags from the previous flight are still on board because the doors could not be opened at the previous destination. There are also wind limits on 'ambu-lifts' and catering trucks and you don't need much imagination to guess the effect of string winds in these vehicles.
With regard to this weather system and the UK, I rethink unless you wish to fly into or out of a northern U.K. airport on Friday pm you will be alright. As for ride quality, this will vary hour by hour and mile by mile. But rest assured, we want a smooth ride just as much as anyone else.
