A sharp rise in atmospheric pressure caused havoc with the fine

more than twice what it was yesterday and this led to an airlock

Here's the "story". However, at Southend the pressure rose 10 mb in
12 hrs 8pm to 8 am, hardly an "extreme change". (Source - METARs).

Indeed; roughly a 1% increase rather than the 100% claimed by c2c.
