It does look potentially quite damp with the Thursday looking better than the Friday. We have the added complication of an ex- tropical storm predicted off our shores on the Friday I'm afraid and that makes it very difficult at this point in time to forecast as it depends on how that develops over the next few days.
To my very untrained eye (I'm trying to learn how to read these weather chart thingies but OYBBK is the expert here in the weather department!), I think Thursday (the 13th) looks fairly settled but the Friday, I think there could be some weather systems trying to come in from the west, so that could mean rain. Hopefully OYBBK will be along to add some detail/correct what I've said soon!
