Operational RAP/HRRR update for wind gusts

As a note to myself:

AUTHOR:   Stan Benjamin
  DATE:     3-November-16 1459Z

A change was made in the wind gust diagnostic calculation for the operational
RAP and HRRR yesterday (2 Nov 2016) starting with the 14z run. This change
reverted to use of a theta-v profile PBL depth for the wind gust diagnostic
instead of using an alternative hybrid PBL-depth. Use of the hybrid PBL was
resulting in too-strong wind gust fields at nighttime. More information is
available in
