Xmas Day Darwin...a little treatise I put together for our local FB weather page.
"OK Pilko - ites, to help take away the guess work, voodooism, witchdoctory, medicine manism, shamanism, tea leaf readers, magic mushroom ingestors AND some BOM employees who lurk around these pages...not to mention the modern model muppets who blindly follow the 'Big Brother' eye-in-the-sky hocus pocus ( you know, the same bastards who think the world is round, and man actually landed on the Moon )
Well here it is, Xmas Day Data ! Darwin Airport since 1941

So will it rain tomorrow ? Probably...
What totals we looking at ? Buggered if I know, ask a witch doctor haha. I do stats, not predictions.
As usual, the timing of the monsoon onset certainly impacts on rain fall and max temps
