MEDIUM TERM FORECAST - SPRING WEATHER STARTING TO GET INTERESTING

After a fairly quiet week of weather, many are wanting rain in SA and QLD, some are wanting no rainfall in NSW and VIC, some want heat and others want the cooler weather. Weather can't be all things to all people at once, so let's see who is getting what and deal with what's ahead.

Rainfall This Week - September 10-17 2021

Lean rainfall chances for the eastern inland, but hints that moisture may run down the spine of a weaker trough over western inland parts of the nation, and lifting into scattered cloud with showers and thunderstorms about. The east coast looks good to receive some reasonable rainfall with onshore winds, mainly over NSW. The tropics turning soupy with build up conditions developing.

Rainfall Next Week - September 18-25 2021

Rainfall chances picking up in the second half of the outlook with moisture content in the atmosphere increasing and pushing south and southeast ahead of cold fronts and troughs. Rainfall totals will increase for some locations as we get better data on frontal weather passing southern areas of the nation.

Rainfall Anomalies - Next 2 weeks - September 10-25 2021

Rainfall anomalies paint the picture of the transportation of moisture from the north via those upper northerly and northwest winds through Central areas of the nation into the southeast of the nation during the coming fortnight, with the first hints of that beginning as early as mid week with outback showers and storms developing for SA and WA, a sign of that moisture running down into a weak inland heat trough. This is what we need to see in the coming weeks to support rainfall chances increasing.

Temperatures This Week - September 10-17 2021

A colder pop of air will ride up the southeast of the nation this weekend with a southerly and southeast flow keeping temperatures near or below average next week over the eastern states. Warmer weather returns to northern and northwest Australia, with build up weather over the NT and western Cape York.

Temperatures Next Week - September 18-25 2021

The warmer northwest flow aloft will drag the central desert air through the south and east of the nation ahead of a long wave in the mid month period, some very warm air may begin to clash with that significant pop of colder air passing over southwest WA. That could see a low form, and if that is the case, some very warm to hot weather is possible for southern and eastern Australia.
