I know you shouldn't put too much faith in GRIB quant methods
We've found them remarkably accurate offshore, but of course less so close inshore where there are many other factors.
There are substantial differences in the BBC pressure charts and teh Met Office ones - which is odd, as I assume they comne from same place. Neither look windless to me, but not strong either. However, the inshore forecast disagrees rather alarmingly, the latest for 1300 Thursday - 1300 Friday is suggesting:
Wind Northwest backing south, 5 to 7, perhaps gale 8 later.
Sea state Slight or moderate, becoming rough.
Weather Rain or showers.
Visibility Moderate or good.
If that proves accurate then there is a high percentage chance that will be in the T&T on Thursday night - and Fairwinds will still be in Balvicar Bay! We will then meet up with the Dunstaffnage contingent on Friday. However, all may change - 24 hours is a long time in the current synoptic situation.
