air temperature usually changes as a front passes by because they have boundaries between two air masses thus, the boundary is forced to change.

A Cold Front has Cold Air, that means you can expect a Temperature drop from this front. Most of the time, when a Cold Front passes over warm areas, you can expect storms to pop up along this front.A cold front will usually bring cooler weather with a sharp change in wind direction and clearing skies.

The front you are referring to is likely a warm front. When a warm front passes, warm, moist air replaces cooler air, leading to an increase in temperature and humidity levels. As the warm air rises, it can also result in cloud formation and precipitation, often manifesting as steady rain or showers. This transition typically creates a noticeable change in weather conditions.
Fronts bring a change in wind direction and speed. As a front passes an area, the wind will shift in direction, and the speed may increase or decrease depending on the type of front (cold front, warm front, stationary front, or occluded front). These changes in wind are often accompanied by shifts in temperature and precipitation.
Wind direction will usually be backing 30 to 90 degrees when a cold front passes through. So if you have southerly winds before a front, they will back to westerly or south westerly winds after the front.
A barometer reading would change with a cold front because the density of mercury will change with temperature, so a reading must be adjusted for the temperature of the instrument. For this purpose a mercury thermometer is usually mounted on the instrument. Temperature compensation of an aneroid barometer is accomplished by including a bi-metal element in the mechanical linkages. Aneroid barometers sold for domestic use typically have no compensation.
When a cold front passes, it typically brings a sudden drop in temperature and shifts in wind direction. The weather associated with a cold front often includes increased cloudiness, precipitation, and sometimes severe storms, such as thunderstorms. After the front moves through, conditions usually clear up, resulting in cooler and drier air.
The wind will increase and the temperature will drop. In addition, rain will usually fall along or near the front.
drop in wind speed
The air behind a warm front is typically colder than the warm air associated with the front itself. A warm front occurs when warm air rises over colder air, leading to a gradual increase in temperature as the front passes. Once the warm front has moved through, the air that follows is usually cooler, as it comes from a different region that is generally at a lower temperature.
The pressure is always lowest at the frontal boundary, whether warm or cold. ______________________________________________________________________ The pressure would decrease since warm fronts are found at the front of low pressure systems. Pressure can also decrease at the warm and cold frontal boundaries just like the previous answer states, but can only increase when the cold front passes.
