It is absolutely steamy at the moment! Hot with temperatures already into the 30's and dew points in the 20's. According to the GFS model, ti will get hot but a boundary will exist in the Sydney basin. If dew points can maintain aloft allowing for relatively rich moisture, storms will develop again this afternoon. Upper levels are passed the ridge from about Sydney and south so destabilisation is starting to occur. Should be some lightning active storms again this afternoon.
