.DISCUSSION...Expecting mostly dry conditions during the day
today, outside of a marginal chance of a light shower over the
site. Better chances for precip will occur overnight tonight, with
a rain/snow mix possible as a weather system moves in from the
southwest. Confidence on the site seeing meaningful precip with
this system is only low to moderate, however. Otherwise expect
winds to become on the lighter end mostly out of the west over the
coming days.
