I said we've been lucky so far, but I spoke too soon.
The top story in the weather for today is the danger from particles in the air.
Our prevailing wind has shifted overnight from a powerful northern cold front, back to a normal pattern and we are getting north easterly winds bringing some of that wildfire smoke our way.

Still the weather service recommends that any with respiratory conditions remain indoors or wear N95 masks if they must go out.
I have plenty more garage work to do, but I want to invite that 48 degree air inside my space before the heat takes over again.
