No-one has mentioned the large amounts of rain this will bring
to the south (according to GFS). I think the greatest problem this
could bring would be flooding given that the ground will be saturated
or snow-covered.

The Stour north of Christchurch near here is pretty much ready to spill
its banks. Already large pools of water (ice today!) where the ground
can't absorb any more. Any more significant rainfall could tip the balance.
