.DISCUSSION...
A few clouds over the site this morning, but these are expected
to continue to through 0900. Showers and thunderstorms will be
possible again this afternoon, developing by 1400, but will be
more isolated (10 to 30% chance) in nature. Wind gusts over 40 mph
will be the main threat from these storms, but brief heavy rain
cannot be ruled out either. Otherwise, winds are expected to be
light through the day. The threat from these storms will end by
sunset, with clearing skies through midnight. Chances for
showers/thunderstorms are even lower for Wednesday, with most of
the activity occurring to the east.
