Radiosonde is launched into deep layer of precipitation, rain at surface
Temperature will be near dewpoint in all layers
There will not be much further
evaporative cooling since air is already or nearly saturated
Temperature and dewpoint may slightly diverge with height. Dewpoint becomes more difficult to calculate
at low pressures and low temperatures
(at temperatures below freezing frost point is higher than dewpoint also).
