In the short-term, for Wales and south Pennines expect ongoing flooding from high rainfall on Friday, the rain eases into Saturday here. A lot of dry weather for Scotland this weekend, but some snow flurries move in from the north on Sunday. Areas of showery snow over the hills into next week coming in on often strong northerly winds, gale force into midweek. Snow most frequent toward north of the Highlands with some locally more substantial accumulations over higher terrain; some accumulating upland snow possible more widely during Tuesday as a front drifts southward.
