Some improvement in local air quality

The concentration of silica nanoparticles has apparently decreased overnight.

Maybe the Saharan sandstorm has blown through, or maybe it's something to do with that great commotion last night and the rain gauge having gone from zero to 1.09" since bedtime.

The forecast calls for more thunderstorms this afternoon, and then pretty much all through the week.  Guess if I'm going to do any gardening, I should do it this morning.

I need some rainy days, to force me to sit at my desk and shuffle papers....
