happy to admit i got monday wrong.. but i did note at the time that it was 'hard to say' given lack of usual information and difficulty reconciling the sources i did have. if you look back at my comments vs the images houghy and/or i have posted some days i doubt you'll find much to disagree with.

ok.. not a bad suggestion.. i've started being more specific about the sources for what i describe (this gets more time consuming each day!). The webcams and Cairns airport METAR fit pretty easily under the definition of 'observed weather' though.

Yes.. I have commented on this up the thread as well after doing a bit of my own trigonometry . Inland on the visible image it's quite easy as you can often see the displaced shadows of the clouds on the ground. Working out when on the coast you can see the east from under the clouds is quite a bit harder but most days have not had the kind of clear area offshore that Monday had. Going to need some luck!
