Well done Terry--congratulations!
The teaching part always seems to stress people out, but remember that it is WHAT YOU DO. Relax and trust yourself. Identify what the student wants and needs, and deliver! Keep it simple. Have good reasons for everything you do--including exercises, progressions, descriptions, focuses, terrain, and teaching styles, based on the individual student. You can't go wrong.
Above all, don't try to figure out--or guess--what the EXAMINER would do with that student. You'll never do it, and there is rarely a single "right answer" anyway. Just explain what YOU would do, why you would do it, and how you would do it.
Glad to hear you got some much-needed snow back there!
