Where do you draw the line on IMC and weather challenges?

Another neophyte question:

To be sure, every aircraft has its own set of capabilities and limitations, but I wanted to ask you folks about either your own personal boundaries on weather, or those you'd recommend to other Skymaster pilots. Naturally, weather can be avoided by changing plans, but regardless, what are your maximums and minimums for going up or coming down (assuming you have a choice, of course) for the following (with or without de-icing and other weather resilience technology)? For those that are difficult to quantify--perhaps precipitation--how do you make the call?

To keep it honest, assume you are taking along a friend of the family.

• Ceiling
• Ground Temperature
• Dew Point
• Crosswind
• windspeed
• gusts
• precipitation

What else do you consider before going up in your Skymaster?
