Areas affected…Middle Atlantic
Concerning…Tornado Watch 615…
Valid 090038Z – 090245Z
The severe weather threat for Tornado Watch 615 continues.
SUMMARY…Tornado risk continues with supercells this evening.
DISCUSSION…Remnants of Debby have moved well inland and the center
of circulation is now located over western NC, east of CLT. LLJ is
strengthening across the middle Atlantic with latest model guidance
suggesting this will continue through sunrise as LLJ translates into
northern VA/MD/southern PA. Latest VAD data supports this with 0-3km
SRH now in excess of 300 m2/s2 at LWX. Numerous small supercells are
embedded within a larger precip shield, supported by moist low-level
warm advection. Radar data suggests several of the more robust
circulations have possibly produced tornadoes at times. While strong
shear persists across portions of the Carolinas, with time the
primary focus for organized supercells will begin to shift north
across VA into MD.
