It's been pretty uneventful weather-wise the last 2 weeks.
Looks like Christmas Day will be dull and rainy for most of the country with the oncoming set of complex lows off the Atlantic, leading to some possible spot flooding in the SE.
Afterwards, slightly colder air looks to be introduced over the country as the next front moved in. Note number of Isobars on the chart so it'll be quite windy too.
GFS is inline with UKMO and so is ECM with only slight variations.
Current indications suggest wintry showers on the back edge of the system
Snow potential above roughly 200m
One to keep an eye on. Like the system on the 10th, a nudge north or south will make a big difference.
