circumstances: sub-tropics. 11 pm daylight time. 83 degrees. est. 76% humidity, pressure 30.11 and rising, dew point 74 degrees, light airs [maybe 3 knots] from SSE. visibility 10miles. [data from weather.com]
my altitude about 30 ft. sky clear within visible distance. 15miles + inland.
yet I see repeated lightning in the W and NW, but can not hear the thunder.
How far away is the lightning??

the temperature of the atmosphere affects the thunder sound you hear as well as how far away you can hear it. Sound waves move faster in warm air than they do in cool air. Typically, the air temperature decreases with height. When this occurs, thunder will normally have an audible range up to 10 miles (16 km).
