1016 PM CDT Sat May 27 2017
Areas affected...Upstate SC...Northeast GA
Concerning...Severe potential...Watch possible
Valid 280316Z - 280445Z
Probability of Watch Issuance...40 percent
SUMMARY...The damaging wind threat will increase later tonight ahead
of a bowing thunderstorm line currently over eastern TN. Downstream
watch issuance is possible.
DISCUSSION...At 03Z, a well-defined QLCS is ongoing across eastern
TN, with the Knoxville ASOS recently reporting a 49 kt wind gust.
There remains some uncertainty as to the intensity of this system as
it crosses the Appalachians, but given its well-organized appearance
and the presence of sufficient buoyancy and shear downstream, some
damaging wind threat is likely to persist into the overnight hours.
Downstream watch issuance into portions of northeast GA and upstate
SC is possible if it appears that sufficient intensity will be
maintained into those areas.
