As far as the weather went, Boxing Day was a day of contrasts.
The barometric pressure fell dramatically – dropping 29mb from 8.00am to 11.00pm. This is known to meteorologists as an ‘Explosive Cyclogenisis’ (a fall of at least 24mb in 24 hours) or, as the press headlines have it, a ‘weather bomb’.
An hour before midnight the pressure started to rise, the wind veered into the northwest and the air temperature, which had been rising steadily all day, fell very rapidly from 8c to 2C.
Just before and after midnight the wind strength grew with several gusts reaching 35mph.
Over the course of a very wet day the accumulated rainfall measured 14.8mm, which made it the wettest day so far this month. The rain stopped just before midnight and the strong wind, with reduced humidity, dried up the evidence of this considerable rainfall.
The accumulated precipitation for December is now 60 per cent of the 30-year average for the month.
