Hi,
Earlier I pointed out "there is an expectation that a band of strong breeze with massive gusts will stretch from somewhere a bit south of Carsington and Derby to the South Coast (and beyond?)". This hasn't changed much.
I guess that the variations in wind forecast at Carsington are due to small changes in the estimated timing of the rate at which this wind band moves southerly - especially as Carsington seems to be around what is expected to be its northerly edge on Saturday - maybe in it, just in it, coming out of it, just out of it or out of it!!
The Met Office only shows 3 hourly forecasts a day in advance, so Saturday forecasts at this level of detail have just come available. The nearest locale is Derby - see

Ignoring one of the 3 readily available Windguru forecasts, but using the other 2, xcweather and Met Office we may have a window in which to sail.
Still watching.......
