I think the potential for storms lies in the interaction of cold front and the warm humid air ahead of it in eastern areas

A much warmer and more humid airmass here than out west (26c with 16-18c DPs), so chance for storms to develop ahead or along of this cold front as the warmer/more humid air is forced upwards. I don't think the chances are great however - I suspect an intensification of the cold front to heavy rain rather than a proliferation of storms.
