That's really awful.
In such a case, I would recommend finding an experienced pilot to fly with (in his plane, with you as a passenger) to keep the cobwebs off, until the wx improves enough to resume the "official training".
I've done that with a few people. It's good fun.
There is little point in banging circuits because circuits just make one sweat like a pig and (due to the stress) have minimal learning value, and flying in bad weather is not much good unless it is done in the context of learning radio navigation (GPS/VOR/DME) which is important but is rarely done in the basic PPL except for very basic stuff.
