None that I am aware of but airlines have preference for where they have staff to assist and/or are sure the right type of equipment for that aircraft type is available.
In true emergencies, the above considerations will have little weight and the "closest" airport capable of handling the aircraft and passengers will be selected. In non-emergencies, the convenience for the carrier will carry more weight.

Weather caused diversions are outside the control of the carrier, so no.
