Usually with EMP from lightning strikes, you will see a quick rise and fall in the noise floor that corresponds with strike. I have also heard (and seen) a slow rise in the intensity of QRN over several seconds an then it drops down.

There are some severe storms approaching the area although not very close. My panadapter display looks like the scalloped edge of a table cloth or something. EVERY 10KHz the signal peaks and there is a squawking noise at the peaks. No signals and this is on EVERY HF band. Is it the storm or is there some other creepy thing going on?
