Scott,

You might consider viewing a radiosonde flight or aircraft soundings when you see a near-adiabatic saturated layer to see what the sounding really looks like. The chance of seeing such a layer near a radiosonde launch at the right time is probably small, so you might consider looking at the ESRL aircraft data web http://amdar.noaa.gov/java
There are about 50 turboprop aircraft flying around the eastern and central United States with pretty reliable ice sensors (they report ice or no ice, not severity). If you load the above page and click the select button, just choose 'icing' and you will see the flight tracks. The web page has a three year running archive, so you can look through data, find icing reports, and then click on the flight track to see a real sounding generated by the aircraft. One thing to remember is that the data can be intermittent when icing is occurring, as a heater comes on to melt the ice from the unit, corrupting the temperature and relative humidity for a short time. Either way, the web page is a great way of locating icing situations and seeing soundings in that vicinity. If you have trouble accessing the page, send me an email to the address above.
