Plotting Radial WS with Leading Times
====================================
This script plots the 850 hPa radial wind speed with leading times. The `radialAvg.ncl <https://github.com/E3SM-Project/ACME-ECP/blob/master/components/homme/dcmip_tests/dcmip2016_test2_tropical_cyclone/preqx/radialAvg.ncl>`_ needs to be staged to the same directory as the example ncl script below.
