Although most of us will remain mild on Christmas day – with the exception being Scotland & Northern Ireland where it will turn colder with snow above 1,000ft, 300mtrs elevation, it will turn colder nationwide on Boxing day and that cold weather will last into the 27th and 28th of December.
There will be a return of night time frosts, a risk of ice after any day time moisture and yes a risk of some snow – especially but not restricted to hilly areas. It turns colder for all on Boxing day with a patchy frost early on, most areas will be fairly bright however later in the day and into the afternoon some heavy rain will arrive – which could turn to heavy & disruptive snow in places. Again – it’s too far out to suggest where the dividing line between rain/snow will be on Boxing Day evening – however the risk is increased during this time for some heavy, wet snowfall.
Not everywhere will see it of course, it’s most likely that Scotland & Northern Ireland will remain dry and south of the M4 corridor it will remain to warm for snow, however places in between face that snow risk through the afternoon and evening, again exact details will be issued nearer the time regarding the significant snow however
