In reply to Andrew95:
Right now, in the south and west, easterly airflow all day, which is good. Seems to gradually get colder as you go north, so Wales might be ok, esp higher up. Met Office say rain in Dorset, however it's been snowing all night, so I'm thinking they got the boundary wrong between the westerly airflow in the Channel and the easterly flow over the UK.
Looking ahead, Thurs/Fri a big low goes through, so wet and windy. Weekend calm and miserable but could be colder in Wales and further north.
Prepare for an icy mudfest
