Pressure is merely force per area, so if the force increases but the box stays the same size, the pressure has increased. Air density can decrease with temperature if pressure is also decreasing. If pressure is constant, this cannot happen (they would be inversely related). Any time you specify a relation between any two of pressure, density or temperature you must hold the third constant or specify its behavior.
Barometric Pressure and Weather Conditions. General Observations. Low and High Air Pressure Low air pressure= less weight pushing down= air is rising and cooling which helps form clouds. High air pressure= more weight pushing down= air is sinking and warming with less humidity. Falling or Low Barometric Pressure Deteriorating weather or some form of precipitation such as wet and/or windy conditions and thunder in hot weather are associated with falling barometric pressure. As a storm approaches air pressure begins to fall and this can happen very quickly.
