I'm another that studiously peruses the forecasts from BOM, CFN & Skippy Sky to try and get an idea of what to expect for the nights observing. Local topology can have an effect that the generalised forecasts can't predict. Taking tonight as an example, has been light breezes and mild temperatures all day and the forecast was for clear skies, which we have but the Jetstream was also supposed to be fairly calm along with the low level winds. Instead of steady seeing that I was looking forward to as I wanted to catch the Europa transit on Jupiter, the seeing was terrible. Probably because the light breeze was coming down from the NW, from the centre of the continent, any time the winds come from that direction, no matter how light, the seeing is always compromised.
