For Research Flight 12 the C-130 flew 7.1 hours in cumulus/stratocumulus
clouds over Lake Huron and Georgian Bay.  These lake-effect clouds were
widespread, and contained mostly ice particles with only occasional liquid
water drops.  The C-130 was able to get a box, such that measurements from
500 ft to 15 kft could be obtained.  Cloud top temperatures were as cold as
-37 degC, and liquid water was observed at temperatures nearly that cold.
As the day progressed, the convective clouds became more organized with
beautiful squal-line like clouds with very distinct gust fronts and with
very dense snow-fall behing the squalls.  Between the clouds were clear
air regions.
