I have found it to be a good predictor of QRN condx on 160 and 80m.

Pretty strange,  I tried this on two different browsers and I cannot receive the site. I used to be able to do it.  It was a great tool in my view and was introduced to me by W1IA Brent.

 :oops:    :!:  :?:  :cry:    :?

Thanks Don, I just added it to all my other esoteric weather links.

Using Windows IE, site came right up.

I get it using Mozilla Firefox.  IE worked ok too, last time I tried.

That might come in handy when chasing E-openings on 6 in the summer.

I think LightningStorm.com is the best one, but here are some more free lightning map websites.  Some of these are not real-time maps but indicate where the most lightning prone regions are located.

I don't recall seeing any direct connection between lightning and E-openings.

As cold and warm fronts bounce into each other, tropo, or tropo ducting, is common on signals above 100 MHz along the cold/warm boundary.

Pete, I was taught that the resulting wind shear from thunderstorms above a certain height ,  ionize patches of the E-layer ,causing openings called sporadic -E .  I have noticed some tropo on 6 , but  it's much more prevalent on 2 meters and above. On the other hand  the MUF for E-openings rarely makes it to two meters and above.
