The effect of dust storms is to loft water vapor into the middle atmosphere, with a significant decrease in absolute humidity near the ground. This reduction in the amount of water vapor means that the formation of films or brines is even less likely during a dust storm despite higher minimum temperature or minor variations in atmospheric pressure.

I am more interested in the aftermath of the dust storm, when (hopefully) Opportunity will be able to observe changes in the resultant dust deposits. Is the above hypothesis still applicable at that point?

I don't think there's really an appreciable pressure signature from dust storms, but this has been measured. Note that some of the graphs below are more about diurnal variation in pressure and less about absolute pressure.
