Temperatures in New South Wales are forecast to exceed November averages by as much as 15 degrees later this week as a heat wave rolls in.
Tomorrow it is expected to reach 35 degrees in west Sydney, and on the weekend it is expected to exceed 40 degrees on both days.
South Australia will be the first to experience the heat wave with conditions possibly reaching severe levels in some inland regions.
The watering holes are bringing rain and storms to Queensland, the Northern Territory and Western Australia, some heavy, while also drawing heat.
A cold front cutting through the southwest corner of WA is generating some rain. The skies are mostly clear in South Australia, Victoria and Tasmania under a wide high pressure system.
After an exceptionally dry November for most of Australia, there are signs that wet weather could increase as we move into December under the influence of the Madden-Julian Oscillation.
The Madden-Julian Oscillation, often referred to as the OMJ, is a region of increased stormy weather that travels around the world every 30-60 days, moving from west to east near the equator. When the OMJ is near the Australian longitudes, it usually causes more rain and storms to develop on our continent. It can also help generate tropical cyclones in Australia’s area of responsibility.
However, when the MJO is near Africa or over the Indian Ocean, we typically see below-average rainfall over large parts of Australia.
During November, the OMJ passed over Africa and the Indian Ocean. As a result, most of Australia has received below-average rainfall this month. The lack of rain and clouds this month has also caused a significant build-up of heat, which will spread across the south and east of the country later this week.
But there is some positive news on the horizon for those who want to see the rain return to Australia.
Forecasting models suggest that the OMJ will move along the Australian longitudes as we move into the first week of December. While the MJO is expected to be relatively weak when it passes near Australia, it should be strong enough to increase rainfall in parts of northern Australia.
It can also help produce the first tropical cyclone of the season in Australian waters.
