The bus is going down because it's just driven over a sinkhole and there's no road underneath it?

Well, that's a bit too much of a hint. It's filled with helium and going up, the hot weather is increasing the effect of the lift enough for the bus to become airborne

The ideal gas law is pV=nRT where:
p is pressure
V is volume
n is the number of moles of gas (how much gas there is)
R is the ideal gas constant (8.314 joules per Kelvin per mole)
T is the temperature
For the inside of the bus, which we assume to be sealed or all the helium would escape, as the temperature increases n and R cannot change (we have not changed the amount of gas and the gas constant is a constant value). Therefore, since the volume cannot change (the bus cannot get noticeably bigger or smaller) the pressure of the helium inside must increase.
Outside there is no constriction on volume and the air outside expands in volume, keeping approximately constant pressure ("atmospheric pressure").
Therefore, because the helium in the bus has increased in pressure relative to the air outside the bus, it can push back harder against the FSM's noodly appendages and rise into the air. QED
