Well, if I was you I would put my money on Tuesday.
Today poor until the afternoon when it should be flyable
Tuesday, light southwesterly, day of the week (probably)
Wednesday, still ok, a bit more wind, a bit more moisture about
Thursday, brisk WSW with more moisture than Wednesday, however if a little more round to the west and less moisture could be worth keeping an eye on
Friday very brisk, very moist.
