[OT] Remarkably dry air in Sydney
Some hot and remarkably dry air has spread across Sydney, Australia in recent
hours accompanied by WNW winds gusting to 30 knots. As a consequence, the bushfire risk is very high. METARs below. For anyone not familiar with METARs they show that the daytime temp has been 36-37 deg with dew points as low as minus 17 deg.
