Well, I am a betting woman (occasionally).
Sorry, but I would give you odds of about 10:1 against
But, on the other hand, I am an eternal optimist, so I would probably go to the airfield, & hope that the weather is better than forecast.
Looking at the forecasts, I would guess it will be as follows:-
Wait around until about 0900 to 1000Z for mist to clear.
Get airborne ASAP, before the fairly solid 6-8/8 cloud arrives at around lunchtime.
Wait at Sywell or Cambridge, till mid afternoon, when hopefully the cloud should have thined out, to enable a quick dash home.
Stapleford, Sywell & Cambridge all have a choice of runways, but even so check cross-wind limits, as the 18 hour TAF (for Stanstead) gives:-
TEMPO 1217 17016G26KT
OR ..... wait till the weekend, when the weather is forecast to be much better.
BUT ... of course, it won't be, 'cos its a Bank Holiday!
Happy & Safe Flying
