Wednesday 1st May 10.15a.m. Mostly sunny, sky clearing. Moderate 24.1 / 40.8kph SW, Hg 50%, 17.2C / 63F top of 18C / 64F. Showers all week, apparently.
Moon is 55.1%
Rain could fall for 10 days straight along the New South Wales coast as weather systems over southern Australia grind to a standstill.
The prolonged drenching will result from a "blocking high", the name given to a high-pressure system that stalls from several days to several weeks, and blocks the typical eastward movement of weather.
This stalling of pressure systems removes the standard day-to-day variability typically experienced in mid-latitude climates like Sydney, leading to an extended spell where the weather is almost identical each day.
While some blocks lead to warm and sunny weather, this week's pattern will bring cool and showery weather to the NSW coast, intensifying into areas of heavy rain this weekend which may even culminate in another bout of flooding.
Not good, if it happens.
