Last night on the AM broadcast band, the stations up and down the
East Coast that traditionally boom in were not so strong.

The Canadian station on 740 which is usually all there is had some
obvious competition from stations in the SW... Texas/Oklahoma? Also
the stations from upstate New York which normally boom in had other
signals fading in and out against them.

And WGN which is not all that reliably received here in Washington
DC was booming in real strong.

Is this possibly related to the strong weather that has been moving
through the midwest (and is due to hit here on the E Coast
tonight)? Or is it just a sign of the end of Winter MW propogation?

It's possible that the presence of strong ionization in the
atmosphere caused by violent winds could steer or even absorb or wipe
out signals. Also, the earth's magnetic field is becoming weaker and
erratic. The field is going to affect how signals propogate, and if
the field changes because of the solar wind, that will also affect
it.

The lower ionosphere goes as low as 50 km to the top of the
stratosphere where it's possible the jet stream could affect it. Our
weather in the troposphere can't though.

My compass is still working so the earths magnetic field is still OK.
