.DISCUSSION...
There is a chance (around 20%) of a shower or storm at/near the
site this evening, but the potential for additional wetting rain
is quite low. Expect winds to settle down somewhat in the wake of
a line of showers and storms that moved through earlier this

lower terrain near Centennial, to as high as around 80% at the
ridgeline.
