Barometer

That's where the old term, "a falling glass" was coined.
It referred to the barometer falling. Actually the barometer didn't fall the mercury, other liquid, or in the case of an aneroid barometer the needle fell.
I saw a 'fall' at one of the buoys in the GOM prior to Dennis.
The 3 hour pressure trend was -10.5 millibars.
That's roughly 0.31" of mercury. A third of an inch fall in 3 hours.
That ought to make your ears pop.
