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?
