It will fall.
Barometric pressure falls with the approach of a cold front or occluded front because these fronts bring denser, cooler air that undercuts the warmer, less dense air ahead of them. This lifting of the warmer air decreases the surface pressure, causing the barometric pressure to decrease.
A good time to fish using a barometer is during a stable or rising pressure, which often indicates clear, pleasant weather and active fish. Fish tend to feed more aggressively when the barometric pressure is steady or increasing, as it can signal an approaching weather front. Conversely, fishing tends to be less productive during rapid drops in pressure, often associated with storms. Additionally, many anglers find success during the hours around dawn and dusk, irrespective of barometric conditions.

As a warm front approaches, the pressure typically decreases. This is because warm air is less dense than cold air, and as the warm front moves in, it displaces the cooler, denser air ahead of it. The resulting decrease in atmospheric pressure can lead to the development of clouds and precipitation, as the warm, moist air rises and cools. Overall, the approach of a warm front is often associated with a gradual drop in pressure.
When a cold front displaces an air parcel upwards, the pressure of the air parcel decreases. This occurs because as the parcel rises, it expands due to lower atmospheric pressure at higher altitudes. The decrease in pressure can lead to cooling and condensation, often resulting in cloud formation and precipitation.

As a cold front passes, the barometric pressure typically decreases. This is because the colder, denser air associated with the front is displacing the warmer, less dense air ahead of it, leading to a drop in pressure.
When the barometric pressure rises it means calm fair weather is coming or is already occurring. When the barometric pressure falls it means foul weather is on the way such as rain and storms and clouds.
It is likely that a warm front is moving into the area, causing the temperature to rise and the barometric pressure to decrease. Warm fronts typically bring warmer air and cloudy, potentially rainy weather.
cold. Low pressure indicates hot air. Rapidly dropping pressure indicates high winds and a possible storm front.
Assuming we are using a pressure transducer to measure barometric pressure, I understand that a gauge type transducer would be used. The internal diaphragm would have a fixed pressure behind it (at a guess would be at standard temp/pressure, STP, ie 20 deg C @ 1013mb), so the transducer has a reference to work against. The front of the diaphragm would be exposed to atmosphere. I would assume the reference (gauge) pressure would vary as the barometric pressure varies, as the diaphragm would move towards the side with least pressure, or at 1013mb the diapragm would be in the centre (which could be used as the null output voltage), higher than 1013mb could produce a positive voltage swing, less than 1013mb could go negative. This is all I can think of, please let me know if on the right track.
