I see the current run now takes it down to 987hPa.Overnight development rather rapid with the messy
baroclinic zone now well organised into a comma shaped mass-

A difficult period for the 'fine-tuning' forecaster this one: the
general forecast looks good, but getting the detail right for such as
Wimbledon is tricky. Note the dark slot on latest WV imagery driving
east across area FitzRoy and the rapidly cooling & expanding tops west
Biscay.

The surface 0600Z analysis gives a hint at just how complex things are!

A GFS forecast run of 310K EPV I saw a couple of days ago-

A second one comes out of the Canadian maritimes to form the weekends 'new' low

Outside of the rain/showers, I was wondering if strong winds alone can stop
play ?

.... Certainly going to be difficult over the next couple of days, but I
can't bring to mind an occasion when that happened - it is usually rain
and/or bad light that will stop things. I think *usually* these other
weather factors will interfere; it may have happened in other
tournaments though. (What will Sue say if 'bad wind stops play!)

Could anyone tell me what it means when the met plot an occluded front as in
the one just SW of Cornwall on the chart above, but it has no line
associated with it, just the symbols?

Thanks,

In this case it indicates the feature in undergoing frontolysis.

Lol ! Must admit I can't think of it happening either.

Already a downed branch in evidence here; doors banging etc - probably
should close the windows a bit
