Weekly Update: 13th December 2024

Highlights:

• Rainfall over the past week has reached nearly every part of the country, just as the forecast indicated.
• Now we still have plenty of moisture, but the pressure pattern has changed - keeping the heavier falls in the west and northeast - but not through much of the southeast.
• Instead heat will surge into the southeast in a big way early next week, potentially challenging records.
• We take a look at week 2 - Christmas week - where larger areas of the country are looking drier than average... and that also leads to the potential for heat.
• Today's update is located in a slightly different spot at Jane's Weather - we have a new look for all of our blog and help centre content, that we will add lots of helpful articles to over the next few months. You can find my weekly updates here.

In this series I'll take you through the drivers of our weather, highlighting any changes over time and things to watch out for (generally every Friday). It covers weather elements like temperature and rainfall, and how they are driven by moisture from the Pacific and Indian Oceans, as well as bursts of energy from low pressure (SAM and MJO).

See and hear my commentary as I take you through the weather pattern's effects on our rain and temperatures in detail over the next week, with a brief look at week 2 and beyond as well.

Plus what is driving our weather in the weeks and months ahead, with the latest on El Nino/La Nina, the Indian Ocean Dipole (IOD), the Southern Annular Mode (SAM controls our weather systems), and the Madden Julian Oscillation (MJO connects tropical moisture to our weather systems).

I update this commentary each week, generally on Friday's. Make sure you are signed up (free or a subscription) so you don't miss an update.
