UK Outlook for Sunday 22 Jan 2012 to Tuesday 31 Jan 2012: Sunday is likely to be chilly and windy, with a mixture of sunny spells and scattered showers. Showers should be most frequent in the north, with snow on hills, whilst the south should remain driest. Similar conditions will likely persist through the following days, with further showers and some more persistent rain likely to affect many areas. Temperatures will probably be near average, occasionally mild, but with overnight frosts possible in any quieter interludes. There is considerable uncertainty regarding the weather during the last few days of January. The slightly more probable scenario at present is that conditions will remain similar to those described above. However there is also a significant risk of much colder weather becoming established right across the UK, with snow in places and widespread overnight frosts.
