Narrative:

Inter-hospital transfer. After pick-up and departure weather progressed two hours faster than originally forecast and crew experienced IMC conditions enroute. After coordination with operations; initial divert was made and coordination for a tail-to-ground transfer approximately 10 minutes into flight as weather was still forecast to be VMC at [destination] for another hour and half. [We then] experienced unforecast icing and snow squall line rapidly approaching from the west that made further VMC flight not possible. After discussion with the crew the pilot identified the first safe point of landing and the aircraft was safely landed onto an alternate unprepared zone; a snow-covered road. Aircraft was secured. Patient transfer was safely executed to complete remainder of the medevac with the aid of the fire dept. No injury to personnel; property; or the aircraft was incurred.
