Areas affected...Central and Eastern North Carolina

Concerning...Severe Thunderstorm Watch 228...

Valid 162212Z - 162315Z

The severe weather threat for Severe Thunderstorm Watch 228
continues.

SUMMARY...The severe weather threat will continue for a few more
hours.

DISCUSSION...A few supercells and multicell clusters continue within
watch 228. The strongest storms are in eastern portions of the watch
where the greatest instability is present. Farther west, the airmass
ahead of these storms has cooled as an outflow boundary has surged
ahead. Therefore, enough instability exists in a moderate shear
environment (30-35 knots) to support some severe weather threat, but
the greater threat remains farther east. The severe weather threat
remains more questionable in southern portions of watch 228. A few
weak storms have developed in northern South Carolina, but have
remained sub-severe thus far. This airmass has not been impacted by
earlier convection, but dewpoints have mixed into the low 60s.
Therefore, some strong to severe storms are possible, especially
near the sea breeze boundary where greater low-level moisture is
present, but the lesser instability may also preclude more robust
thunderstorm development.
