.DISCUSSION...

Showers are developing in the Smokies, to the north and south of the
SAR site at this hour. This will progress in coverage and expect
showers and thunderstorm activity to be ongoing at, or within 5 miles
of the SAR site 230 PM EDT. Expect this to continue off an on through
the evening hours. Overnight, cannot rule out additional thunderstorm
activity, but uncertainty in coverage and location preclude giving
much more than a 30-40 percent chance after midnight. Winds should be
generally light, but winds above 30 mph could occur in any thunderstorms
that pass through the SAR site. Temperatures will remain cool at higher
elevations, generally in the mid to upper 60s today and tomorrow.
Additional shower and thunderstorm activity is expected tomorrow.
