A developing storm won't necessarily show rain either. Falling rain

This I didn't know.

I agree that his statement might have meant what you said, rather than
what
I thought it meant.

Frankly, I'm not sure how your interpretations of what I wrote are
different. I think you've both a pretty good grasp of my concern.

But I still don't see how it would imply 'spherics
devices are inferior for detecting thunderstorms.

I didn't write this. I'm trying to find out just how well they work as
avoidance tools, true, but that doesn't imply that I don't like the device.
I don't know enough yet.

Also, while I'm not
positive, if I recall correctly lightning is present in any thunderstorm
where turbulence and strong updrafts are present, regardless of the stage
of development.

From my reading - light yet, I admit - it sounded like lightening occurred
only after the developing stage is well along. It takes time for the
difference in potential to grow enough that discharges occur, as I've
understand what I read.

Did I misunderstand?

There are certainly "almost thunderstorms" that it's best to fly around.

No doubt...but I haven't seen anything that would suggest a Stormscope or
Strikefinder wouldn't identify those storms.

Wouldn't a strikefinder, by definition, not see a storm that wasn't yet a
thunderstorm?

I liked your idea, BTW, about trying the strikefinder experimentally. I was
up in poor-but-VFR conditions this weekend, and I was trying to do
something of that sort. Isolated t-storms were predicted, so it seemed a
good opportunity.

Unfortunately, the visibility was sufficiently poor and there were enough
clouds around that I couldn't really see much at a distance. There were
strikes showing, but I couldn't match them with anything visually.

Also, nothing was clustering. There were regions with indicated strikes,
but of no major density. If I had to guess, I'd say that my understanding
about the time it takes for discharges to occur is wrong, and this is a
demonstration of "near t-storms" appearing on the strikefinder. Alas, this
really is just a guess.

I've more reading to do, in the meantime.
