.DISCUSSION...
No issues overnight as winds will diminish and rain chances come
to an end. However, Saturday looks like an active day with the
possibility of multiple rounds of precipitation in the afternoon
with good coverage as a push of monsoonal moisture arrives into
the CWA. With the proper atmospheric parameters in place, strong
to severe wind gusts will be the primary threat in any shower
and/or storm. There will be a second round of showers and storms
with a second wave that pushes through later in the evening, this
will be more stratiform in nature. Moderate to heavy rain can be
expected with the monsoon push, hence around a 25 percent of
wetting rains, with most of the activity dieing down before
midnight. Additional moisture chances are possible Sunday along
with gusty winds.
