Can anyone determine if a large 36,000 foot ASL convective ash cloud erupted from Mount St. Helens on March 8 at 17:25-18:00 PST produced any lightning that was detectable by the NLDN?

Any lightning in SW Washington State at this time can be attributed with near certainty to the MSH plume and not any meteorological clouds.
 
Glen, there have been numerous reports of lightning associated with
volcanic eruptions.

You might check with the company that records every lightning
strike in the US. I cannot remember their name right now but I
think they used to be called LLP?

Just watched the Forces of Nature IMAX film last Friday. The eruption in that film had lightning popping left and right as the ash cloud billowed from the mouth. It was pretty cool video.
 
The NLDN Glenn mentioned in his first post is Vaisala's U.S. National Lightning Detection Network. The data they have is not freely available to the public. They sell it to places like TV stations, power companies, golf courses, and insurance companies wanting to verify lightning damage claims.
OU keeps 30 days of data on their server, unfortunately this only goes back to March 20, sorry. Perhaps there's someone doing some lightning research that may have some older data.
