A severe thunderstorm watch is not expected. DISCUSSION...A cluster of storms over southeast TN is tracking southward along an instability gradient amid moderate mid/upper northerly flow. MLCAPE values around 1000 J/kg and modest effective shear may allow this cluster to persist another couple of hours. Severe potential is expected to remain limited as convection is behind an outflow boundary from early morning storms. Strong boundary-layer inhibition behind the outflow boundary will limit stronger downburst potential. Some gusts around 40-50 mph will be possible over the next 1-2 hours, but severe potential is expected to remain low and a watch is not expected. ...Leitman/Grams.. 06/30/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!7EZ7zdtNTfOlK7EZeVOQTTQ7JZVBIZM6LFTTA6fR-cucR76r0MPX2OdK8iAa8FMQSKAcxPUqX= ypKUZu2z9SK17RDgaQ$ for graphic product...
