Speaker Notes:

The net result of considering the pressure advection and the local pressure derivative is the adiabatic omega. Note that two maxima of lift are indicated, one over eastern NY (associated with the pressure advection / WAA) and one of western and central Pa (associated with the local pressure derivative / vorticity advection).
