How to determine it is snowing or sleeting?

(1/1)

iisfaq:
Right now it is raining, sleeting, and very just snowing....

It changes quite fast from these 3 things - Here is the data I have for 1 minute.

I store this data every minute in my own database from my own software - I am not using Weather Display, VP, just 100% my own code.

Can you see anything that would let me know that it is snowing or sleeting?

I would like to sort of predict that it is snowing or sleeting from my data values.

Any ideas?

cheers

LFWX:
Surface conditions are not really going to indicate which type of precipitation is reaching the ground.
You would need to know the conditions above your station to help determine this.
