10 days before the great storm, the UK was under high pressure. So some places could have dropped up to 100 millibars in a space of 10 days.

January 1884 was an exceptionally mild month with a CET of 6.5

Remarkably just 3 years after the January 1884 storm, the record came under threat when an exceptional depression tracked across northern parts of the UK  on the 8th of December 1886 bringing with it widespread gales and squalls.

 

 

Belfast recorded a barometer reading of 927mb

 

Those values converted into millibars

Belfast: 927.1mb
Lurgan: 928.9mb
Cronkbourne: 933mb

Here is a graph of very low pressure readings recorded at Camden Square.


It is interesting to note that Camden Square's barometer was below 959mb for just over 10 hours.

A few reports

Stroud: Severe SW gale with thunder, lightning and hail on 8th
Woolstaston: There was a strong gale on the 8th and 9th with lightning and hail and a remarkable and long continued barometric depression, the lowest reading ever observed occurring about 9pm on the 8th.
Orleton: About 7pm, on the 8th, the bar stood at 27.83 inches (uncorrected) which was nearly a tenth of an inch lower than on the 13th January 1843
Haverfordwest: The damage done to forest trees during the great storm of the 7th and 8th perhaps exceeds anything in living memory.
Killaloe: A great storm occurred on the 8th with very low pressure, the period of greatest violence between 10pm and 1am.
Dublin: Pressure exceptionally low on 8th.
Edenful: On the 8th, we were here in the very centre of a barometric depression, lowere even than that of January 26th 1884. The lowest point was touched at 2pm, when a dead calm prevailed, nor was there any atmospheric disturbance till 1am next morning.

Given how deep the models are showing the Christmas Eve low, a reminder.
