0750 AM CDT Wed May 08 2024

Areas affected...Southern Kentucky...Tennessee

Concerning...Severe potential...Watch possible

Valid 081250Z - 081515Z

Probability of Watch Issuance...40 percent

SUMMARY...An isolated severe threat is expected to continue this
morning. The stronger storms will have potential for hail, strong
gusts and a brief tornado. Weather watch issuance may become
necessary later this morning.

DISCUSSION...The latest mosaic radar imagery in the Tennessee Valley
shows numerous thunderstorms along an east-to-west outflow boundary,
from southern Kentucky into northern Tennessee. To the south of this
convection, the RAP has moderate instability in place, with MLCAPE
generally in the 2000 to 2500 J/kg range. Forecast soundings in
northern Tennessee this morning suggest the activity is
surface-based. WSR-88D VWPs along and near the outflow boundary have
0-6 km shear in the 45 to 50 knot range, which will continue to be
sufficient for supercells and bowing line segments. Wind damage and
hail the primary threats. However, VWPs also have 0-1 km shear in
the 20 to 25 knot range near this feature, suggesting that a brief
tornado will be possible with embedded supercells.
