There is strange stuff falling on my roof and in my yard. It appears to be a compound of oxygen and hydrogen, but not having seen much of that lately, I can't be sure. Maybe it will settle those fine silicate particle out there in the yard. Fortunately, it's too warm for it to fall in a solid state. However, if the temperature should drop to 0 degrees C or so, maybe the organic debris in the yard will be hidden so I won't have to rake it up.
This has been the warmest and driest November and December that I can remember.
