I see! I find Metcheck does often feel gloomier. There's some reason for this (my husband, a sailor, once told me the difference between the models that the two sites use to produce weather reports, and is able to make more sense of it, but I can't remember what that was now). I tend to go with the most positive-looking forecast (and then get rained on!)
I saw you had to postpone your ride, that's a real shame! The CC ride of early January had to be postponed because of the weather too, it's so disappointing when everyone's keen. But I am sure the weather will be lovely on Tuesday for all of us. In fact we'll probably overheat or get sunstroke or something!
