SUMMARY...A couple of transient supercells may pose an isolated risk
for a tornado or two through the afternoon. It is uncertain whether
a tornado watch is needed.
DISCUSSION...Radar imagery this afternoon shows developing storms
over central SC to the east and ahead of the center of Claudette.
Additional storms exhibiting supercellular characteristics have been
observed over northeast NC during the past 30 minutes. The airmass
over the Carolina Piedmont/coastal plain has destabilized with
temperatures in the mid 80s and dewpoints in the low to mid 70s.
Based on 88D VAD data, the largest hodograph is observed from the
Morehead City, NC VAD where some veering and strengthening of winds
to 30-35 kt at 2km AGL was noted. Weaker flow was sampled by the
Raleigh, NC and Columbia, SC VADs and their hodographs were much
more limited in size. As it stands, it appears the highest
conditional risk for a tornado is over parts of eastern NC during
the afternoon due to the larger hodographs.
