What would cause my 97 grand cherokee limited to start by its self with no key in ignition after it rains

Welcome to the family and the forum...
You might want to post your question over in the GC section of the forum. Most won't be looking for technical question answering in the introduction section.

Just FYI.... while ALL Jeeps have gremlins and issues.... GC's are also well known for electrical gremlins, even more so than regular XJs.
