Picked up 0.22 inch of rainfall yesterday evening from a storm on a due south heading. That is the only measurable rainfall for the entire month of September IMBY. It is so dry...

Grabbed what was left over from a similar South moving shower  - 0.04". It dissipated while passing through this area.
