Thank you!
I will take a little time to work on the input I have recieved, and post back what I have done, possibly along with a suggestion for some new standard names.

Emne: Re: [CF-metadata] standards for probabilities
Most of the discussion so far has centered on (1). But this raises
some other issues:
> 2) probability that air temperature will be within 2.5 degrees of the forecast
This is clearly trying to get at something akin to what we do with the
"standard_error" standard name modifier and the "standard_error_multiplier"
ancillary variable. The differences are that the units are flipped and
the assumption of a normal distribution is removed.
Can we use something analogous? Maybe a new standard name modifier
like "distribution" or "probability" or "confidence" which requires an ancillary
variable?
The best fit for this particular case is "confidence" with an ancillary variable
"confidence_interval" with value 2.5.
But something more like "distribution" is more general and could be stretched to
handle
> 1) "25th percentile precipitation amount" (based on ensemble data)
Here we might use the "distribution" (or "cumulative_distribution"?)
standard name
modifier, ancillary variable "cumulative_probability", value 0.25.
